MSN Exam for Parkinson’s Disease

EXPLANATION

 

✔Correct answer:

Placing the patient in a chair without using a transfer belt. Placing a patient with Parkinson’s disease in a chair without using a transfer belt is a safety risk and should prompt immediate intervention. A transfer belt, or gait belt, is an essential tool for safely moving patients with impaired mobility. It provides better control and support during transfers, helping to prevent falls and injuries to both the patient and the caregiver.

Patients with Parkinson’s disease often experience muscle rigidity, bradykinesia (slowness of movement), and balance issues, making them more prone to falls. Proper use of a transfer belt ensures stability and reduces the risk of accidents during transfers from bed to chair or vice versa.

Think of the transfer belt like a safety harness used in rock climbing. Just as a harness provides support and prevents falls during a climb, a transfer belt offers crucial support and stability when moving a patient, reducing the risk of falls and injuries.

To ensure patient safety and enhance mobility, Nurse Thompson should prioritize the use of appropriate transfer techniques and tools.

• Ensure all staff are trained in the proper use of transfer belts and the importance of using them during patient transfers.
• Monitor and reinforce the correct techniques for transferring patients to prevent falls and injuries.
• Encourage the use of assistive devices, such as walkers or wheelchairs, as needed for additional support.
• Educate patients and their families about safe transfer techniques and the use of mobility aids.
• Regularly assess the patient's mobility status and adjust care plans as needed to maintain safety and promote independence.

 

✘Incorrect answer options:

Assisting the patient in ambulating with a gait belt. This action is appropriate and safe. Using a gait belt for ambulation provides support and helps prevent falls, which is crucial for patients with impaired physical mobility.

Encouraging the patient to perform active range of motion exercises. Encouraging active range of motion exercises is beneficial for maintaining muscle strength, flexibility, and mobility in patients with Parkinson’s disease. It is an appropriate intervention and does not require immediate intervention.

Helping the patient with feeding using adaptive utensils. Using adaptive utensils helps patients with Parkinson’s disease maintain independence during meals. This action is appropriate and supports the patient’s ability to feed themselves effectively.

EXPLANATION

 

✔Correct answer:

Dysfunction of dopamine-producing cells in the brain. Parkinson’s disease is primarily caused by the dysfunction and degeneration of dopamine-producing cells in a region of the brain called the substantia nigra. Dopamine is a neurotransmitter essential for coordinating smooth and controlled movements. When dopamine levels decrease due to the death of these cells, it leads to the motor symptoms characteristic of Parkinson's disease, such as tremors, rigidity, bradykinesia (slowness of movement), and postural instability.

The substantia nigra is part of the basal ganglia, which play a crucial role in motor control. In Parkinson’s disease, the progressive loss of dopaminergic neurons results in an imbalance between dopamine and acetylcholine, another neurotransmitter involved in movement. This imbalance disrupts the normal communication within the brain’s motor circuits, leading to the symptoms observed in Parkinson’s disease.

Imagine the brain's motor control system as a car engine that requires oil (dopamine) to run smoothly. If the oil runs low due to a leak (death of dopamine-producing cells), the engine starts to malfunction, causing jerky or sluggish movements.

Nurses should focus on managing symptoms, enhancing quality of life, and providing education and support for patients with Parkinson’s disease.

• Administer medications such as levodopa and dopamine agonists to help replenish dopamine levels and improve motor function.
• Encourage regular physical activity and exercises to maintain mobility and muscle strength.
• Provide education on safety measures to prevent falls and injuries.
• Offer support for non-motor symptoms such as depression, sleep disturbances, and autonomic dysfunction.
• Collaborate with multidisciplinary teams, including physical therapists, occupational therapists, and speech therapists, to provide comprehensive care.

 

✘Incorrect answer options:

The natural death of brain cells due to aging. While aging is a risk factor for Parkinson’s disease, it is not the primary cause. The disease specifically involves the selective loss of dopamine-producing neurons in the substantia nigra, not just a general age-related decline in brain cells.

Exposure to injurious chemical substances. Although certain environmental factors and toxins (e.g., pesticides, herbicides) have been associated with an increased risk of developing Parkinson’s disease, they are not considered the primary cause. The core pathology involves the dysfunction of dopamine-producing cells.

Genetic or hereditary factors. Genetic factors can play a role in the development of Parkinson’s disease, especially in cases with a family history of the condition. However, most cases are sporadic and not directly linked to inherited genetic mutations. The primary cause remains the dysfunction of dopamine-producing cells.

EXPLANATION

 

✔Correct answer:

Postural hypotension. Postural hypotension, also known as orthostatic hypotension, is a common side effect of levodopa, a medication used to treat Parkinson’s disease. Postural hypotension occurs when there is a significant drop in blood pressure upon standing up from a sitting or lying position, leading to dizziness, lightheadedness, or even fainting. This happens because levodopa can affect the autonomic regulation of blood pressure.

Levodopa increases dopamine levels in the brain to help control movement symptoms in Parkinson's disease. However, dopamine also influences blood pressure regulation. As dopamine levels fluctuate with levodopa administration, it can impair the body's ability to maintain stable blood pressure when changing positions.

Imagine a well-regulated irrigation system (blood pressure) in a garden that suddenly starts malfunctioning, causing water pressure to drop dramatically when it’s turned on quickly. This sudden drop is akin to the way postural hypotension causes blood pressure to fall when standing up too quickly, leading to dizziness and instability.

To help manage and educate patients about postural hypotension, Nurse Cooper should:

• Teach the client to rise slowly from sitting or lying positions to reduce the risk of dizziness or fainting.
• Encourage adequate hydration to help maintain blood pressure.
• Advise the client to avoid sudden movements and to sit or lie down if they feel dizzy.
• Suggest wearing compression stockings to help improve blood circulation and reduce pooling in the legs.
• Monitor blood pressure regularly and report any significant drops to the healthcare provider for further management.

 

✘Incorrect answer options:

Development of a peptic ulcer While gastrointestinal side effects like nausea and vomiting can occur with levodopa, the development of peptic ulcers is not a common side effect specifically associated with this medication.

Experiencing significant weight loss Weight loss is not a typical side effect of levodopa. Although some patients may experience changes in appetite or weight, significant weight loss is not a primary concern with this medication.

Occurrence of pancytopenia Pancytopenia, a condition characterized by the reduction of red and white blood cells and platelets, is not a known side effect of levodopa. This condition is more commonly associated with bone marrow suppression, which is not related to levodopa therapy.

EXPLANATION

 

✔Correct answer:

Food rich in Vitamin B6. For patients taking levodopa, it is important to monitor and potentially limit foods rich in Vitamin B6 (pyridoxine). High levels of Vitamin B6 can increase the metabolism of levodopa in the peripheral tissues, reducing its availability to cross the blood-brain barrier and reach the brain, where it is needed to exert its therapeutic effects. This can diminish the effectiveness of the medication in managing the symptoms of Parkinson’s disease.

Levodopa is a precursor to dopamine, which is deficient in Parkinson's disease. When taken orally, levodopa needs to cross the blood-brain barrier to be converted into dopamine in the brain. Vitamin B6 can increase the activity of the enzyme aromatic L-amino acid decarboxylase in the peripheral tissues, which converts levodopa to dopamine before it crosses the blood-brain barrier, thus reducing the amount of levodopa that reaches the brain.

Think of levodopa as a special delivery package that needs to get to a particular address (the brain). Vitamin B6 acts like an overzealous mail sorter in the sorting facility (peripheral tissues) that opens the package prematurely, preventing it from reaching its intended destination intact.

Nurse Anderson and the dietician should educate Mrs. Green about dietary considerations to enhance the effectiveness of her medication.

• Advise on limiting foods high in Vitamin B6, such as certain cereals, bananas, potatoes, and meat.
• Ensure Mrs. Green takes levodopa at times separate from high-protein meals, as proteins can also interfere with the absorption of levodopa.
• Monitor Mrs. Green’s response to the medication and adjust dietary recommendations as needed to optimize the therapeutic effects.
• Provide education about the importance of medication adherence and potential dietary interactions with her treatment regimen.
• Encourage regular follow-ups with the healthcare team to assess and manage any side effects or changes in symptoms.

 

✘Incorrect answer options:

Food rich in Thiamine. Thiamine (Vitamin B1) is important for nerve function but does not have a direct interaction with levodopa. There is no need to limit foods high in thiamine for patients on levodopa.

Food rich in Vitamin C. Vitamin C (ascorbic acid) is crucial for immune function and overall health, but it does not interfere with levodopa metabolism. Patients taking levodopa do not need to avoid foods rich in Vitamin C.

Food rich in Vitamin E. Vitamin E is an antioxidant important for protecting cells from damage. It does not have a direct impact on the metabolism or effectiveness of levodopa. Therefore, there is no need to limit Vitamin E-rich foods for patients on levodopa.

EXPLANATION

 

✔Correct answer:

Grasp an object in his hand. One effective strategy to manage a resting tremor in Parkinson's disease is to grasp an object in the hand. Resting tremors occur when the muscles are relaxed and at rest, often diminishing with purposeful movement. By holding or manipulating an object, such as a stress ball, Mr. Parker can engage his muscles in purposeful activity, which can help reduce the tremor.

In Parkinson's disease, tremors are caused by the dysfunction of the basal ganglia and the resultant imbalance of neurotransmitters, particularly dopamine. Tremors at rest are a hallmark symptom of this condition. Engaging the hand in activity can temporarily stabilize the neural circuits involved in movement, thereby reducing the tremor.

Imagine a flag fluttering wildly in the wind when it's left alone (the hand experiencing a tremor). If you grab the flagpole and hold it steady (grasp an object), the flag stops flapping so wildly. Similarly, when Mr. Parker holds an object in his hand, it helps stabilize the movement and reduces the tremor.

Nurses should provide practical tips and support to help patients manage symptoms of Parkinson's disease in their daily lives.

• Encourage the patient to keep small objects like stress balls, worry stones, or hand grips nearby to grasp during periods of rest.
• Suggest engaging in activities that involve fine motor skills, such as knitting, drawing, or using tools, which can help distract from the tremor.
• Teach the patient relaxation techniques and stress management, as anxiety can exacerbate tremors.
• Collaborate with occupational therapists to develop tailored exercises and activities that support motor function and reduce tremors.

 

✘Incorrect answer options:

Immerse in a warm bath. While a warm bath may help relax muscles and reduce overall tension, it is not specifically effective for managing resting tremors. The effect of warmth is more generalized and temporary, and it does not address the tremor directly.

Use diazepam when necessary. Diazepam is a benzodiazepine used primarily for anxiety, muscle spasms, and seizures. It is not typically used to manage Parkinson's tremors and can cause sedation and other side effects that might not be beneficial for Parkinson's patients.

Engage in deep breathing exercises. Deep breathing exercises are beneficial for reducing stress and promoting relaxation but do not directly target the neuromuscular causes of resting tremors. While helpful for overall well-being, they are not a primary intervention for tremor management.

EXPLANATION

 

✔Correct answer:

Levodopa has the potential to induce side effects such as orthostatic hypotension. One of the important side effects of levodopa, a primary treatment for Parkinson’s disease, is orthostatic hypotension. Orthostatic hypotension is a form of low blood pressure that happens when standing up from sitting or lying down, leading to dizziness or fainting. This is particularly relevant in Parkinson’s patients, who may already be at a higher risk of falls due to motor symptoms.

Levodopa is converted to dopamine in the brain, helping to replenish the diminished levels of this neurotransmitter in Parkinson’s disease. However, dopamine also plays a role in regulating blood pressure. As levodopa increases dopamine levels, it can disrupt the body's ability to manage blood pressure, leading to orthostatic hypotension.

Think of the blood pressure system in your body like a well-calibrated thermostat that keeps the temperature (blood pressure) stable. When taking levodopa, it’s as if the thermostat suddenly becomes unpredictable, causing abrupt drops in temperature when you stand up. This instability, much like the sudden drop in blood pressure, can make you feel dizzy or faint, emphasizing the importance of monitoring and managing this side effect.

To manage and monitor for orthostatic hypotension in patients taking levodopa, Nurse Allen should:

• Monitor blood pressure regularly, especially when the patient changes positions.
• Educate the patient to rise slowly from sitting or lying positions to minimize dizziness and prevent falls.
• Advise the patient to stay hydrated and possibly wear compression stockings to help maintain blood pressure.
• Assess for other symptoms of low blood pressure, such as lightheadedness or blurred vision, and report any significant changes to the healthcare provider.

 

✘Incorrect answer options:

Levodopa can lead to an initial feeling of euphoria, which is then followed by a phase of depression. While levodopa can affect mood, it is not commonly associated with an initial feeling of euphoria followed by depression. Mood changes may occur, but this is not a typical pattern related to levodopa use.

Levodopa's absorption can be insufficient if it is administered alongside meals. While it is true that high-protein meals can interfere with levodopa absorption, this is not the most crucial piece of information compared to the risk of orthostatic hypotension. Patients are often advised to take levodopa 30 minutes before or one hour after meals.

Levodopa administration requires consistent monitoring through weekly laboratory tests. Regular weekly laboratory tests are not typically required for patients on levodopa. Monitoring focuses more on clinical assessments of symptoms and side effects rather than frequent lab tests.

EXPLANATION

 

✔Correct answer:

Walking on uneven terrain alone. Walking on uneven terrain alone poses a significant risk to patients with Parkinson’s disease due to their impaired balance, coordination, and potential for freezing episodes (sudden inability to move). These factors increase the risk of falls and subsequent injuries. It is crucial for Mr. Baker to avoid walking alone on uneven surfaces to prevent accidents and ensure safety.

Parkinson’s disease affects the motor system, leading to symptoms such as tremors, rigidity, bradykinesia (slowness of movement), and postural instability. These symptoms can compromise Mr. Baker’s ability to navigate uneven terrain safely. Walking on such surfaces without assistance increases the likelihood of tripping, falling, and sustaining injuries.

Think of Mr. Baker's condition like walking on a tightrope with a wobbly balance pole. Navigating a smooth, level surface is already challenging, but walking on a rocky path (uneven terrain) alone makes it far riskier, increasing the chances of falling.

To ensure Mr. Baker’s safety and help manage his Parkinson’s disease, Nurse Harris should provide comprehensive advice on lifestyle adjustments and safety measures.

• Encourage Mr. Baker to walk on flat, even surfaces and use assistive devices like canes or walkers when necessary.
• Advise him to have a companion or caregiver present when walking outdoors or on uneven terrain.
• Suggest home modifications to reduce fall risks, such as removing tripping hazards and installing grab bars and handrails.
• Provide information on community resources, such as local support groups and exercise programs tailored for Parkinson’s patients.

 

✘Incorrect answer options:

Participating in seated yoga classes. Seated yoga classes are beneficial for patients with Parkinson’s disease as they can improve flexibility, strength, and relaxation without putting the patient at high risk of falling.

Eating a balanced diet rich in fiber. A balanced diet rich in fiber is important for overall health and can help manage some symptoms of Parkinson’s disease, such as constipation, which is common in these patients.

Engaging in mild stretching exercises. Mild stretching exercises are beneficial for maintaining flexibility and reducing muscle stiffness in Parkinson’s patients. They are safe and helpful in managing symptoms.

EXPLANATION

 

✔Correct answer:

A noticeable reduction in voluntary movements. Bradykinesia is a hallmark symptom of Parkinson’s disease, characterized by a noticeable reduction in voluntary movements. This condition involves the slowing down and loss of spontaneous and voluntary movement, making everyday tasks more difficult for the affected individual. Nurse Hernandez’s observation of reduced voluntary movements aligns with the clinical presentation of bradykinesia.

Bradykinesia occurs due to the degeneration of dopaminergic neurons in the substantia nigra, a part of the brain that plays a critical role in regulating movement. The deficiency of dopamine, a neurotransmitter essential for smooth and coordinated muscle movements, leads to the characteristic slowing of movements seen in Parkinson’s disease.

Imagine trying to walk through a pool of thick mud. Every step is slow and takes extra effort, similar to how someone with bradykinesia feels when trying to move their limbs.

When caring for a patient with bradykinesia, nurses should implement interventions that support mobility and daily functioning.

• Encourage the patient to perform physical therapy exercises designed to maintain muscle strength and flexibility.
• Provide assistance with activities of daily living (ADLs) as needed, ensuring the patient maintains as much independence as possible.
• Monitor the patient's medication regimen, particularly their levodopa/carbidopa treatment, to optimize the control of symptoms.
• Educate the patient and family about strategies to cope with bradykinesia, such as breaking tasks into smaller steps and allowing extra time to complete activities.
• Ensure a safe environment to prevent falls, which can occur due to the slow and stiff movements associated with bradykinesia.

 

✘Incorrect answer options:

Inability to move the limbs. This describes akinesia, which is the absence of movement. While akinesia can occur in advanced Parkinson's disease, bradykinesia specifically refers to slowness and a reduction in the amplitude of movements rather than a complete inability to move.

Tremor that occurs with purposeful movement. This describes intention tremor, which is not typical in Parkinson's disease. The tremor associated with Parkinson's is usually a resting tremor, which occurs when the muscles are relaxed and not engaged in purposeful movement.

Sudden, involuntary muscle contraction. This describes dystonia, which involves sustained or repetitive muscle contractions causing twisting and repetitive movements or abnormal postures. Dystonia can be a symptom of Parkinson’s but is not the same as bradykinesia.

✔Correct answer:

Alzheimer’s disease. Alzheimer’s disease is the most common cause of dementia among elderly individuals. Dementia is a general term for a decline in mental ability severe enough to interfere with daily life, and Alzheimer’s disease accounts for approximately 60-80% of dementia cases. It is a progressive disease that causes brain cells to degenerate and die, leading to a continuous decline in thinking, behavioral, and social skills.

Alzheimer’s disease is characterized by the accumulation of amyloid plaques and tau tangles in the brain. These abnormal protein structures disrupt neuron function and lead to cell death. The disease typically begins with mild memory loss and progresses to severe cognitive impairment, affecting memory, language, and reasoning.

Think of the brain as a city where neurons are buildings and streets. In Alzheimer’s disease, it’s as if debris (plaques and tangles) is blocking the streets and causing buildings to collapse, making it difficult for the city to function properly.

To support patients with Alzheimer’s disease, nurses should focus on maintaining safety, managing symptoms, and providing support for both patients and their families.

• Implement safety measures to prevent falls and injuries.
• Promote a structured and predictable environment to reduce confusion and anxiety.
• Encourage cognitive and social activities to stimulate the brain.
• Administer medications as prescribed to manage symptoms and slow disease progression.
• Provide education and resources to caregivers to help them cope with the demands of caregiving.

 

✘Incorrect answer options:

Multiple sclerosis Multiple sclerosis (MS) is a chronic disease that affects the central nervous system, leading to symptoms such as muscle weakness, coordination problems, and visual disturbances. While MS can cause cognitive impairment, it is not a common cause of dementia in the elderly.

Parkinson’s disease Parkinson’s disease is a neurodegenerative disorder that primarily affects movement. It can lead to Parkinson’s disease dementia, but it is not the most common cause of dementia. Cognitive decline typically occurs later in the disease progression and is less prevalent than Alzheimer’s disease.

Amyotrophic lateral sclerosis Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s disease, is a progressive neurodegenerative disease that affects motor neurons. While some individuals with ALS may experience cognitive changes, it is not a common cause of dementia. ALS primarily affects muscle control and physical function.

EXPLANATION

 

✔Correct answer:

Meningitis. Brudzinski's sign and Kernig’s sign are classic clinical indicators associated with meningitis. Meningitis is an inflammation of the meninges, the membranes that cover the brain and spinal cord, often due to an infection. These signs are used to help diagnose the condition.

Brudzinski's sign is observed when the patient's neck is passively flexed. A positive Brudzinski's sign occurs if this maneuver causes involuntary flexion of the hips and knees, indicating meningeal irritation.

Kernig’s sign is assessed by having the patient lie flat on their back, then flexing the hip and knee at a 90-degree angle. A positive Kernig’s sign is present if there is resistance to straightening the leg or if this action causes pain in the hamstrings, also indicating meningeal irritation.

Meningitis causes inflammation and irritation of the meninges, which can increase intracranial pressure and affect the nerves and spinal cord. The positive Brudzinski’s and Kernig’s signs result from this irritation, reflecting the sensitivity of the inflamed meninges to movement.

Imagine the meninges as a protective covering around the brain and spinal cord. In meningitis, this covering becomes inflamed and irritated, similar to how inflamed skin becomes painful and sensitive to touch. Movements that stretch or put pressure on the meninges can cause discomfort or pain, much like touching inflamed skin.

If meningitis is suspected, it is critical to act promptly due to the potential for severe complications.

• Perform a thorough neurological assessment, including checking for other signs of meningeal irritation and increased intracranial pressure.
• Administer prescribed antibiotics or antiviral medications immediately, as meningitis can be life-threatening.
• Monitor vital signs and neurological status closely to detect any changes or deterioration.
• Ensure the patient is comfortable and minimize stimuli that could exacerbate symptoms, such as bright lights or loud noises.
• Educate the patient and family about the importance of completing the full course of prescribed medications and follow-up care.

 

✘Incorrect answer options:

Cerebrovascular accident (CVA) A cerebrovascular accident, or stroke, typically presents with sudden neurological deficits such as weakness, speech difficulties, and facial droop. It is not characterized by Brudzinski's or Kernig’s signs, which are specific to meningeal irritation.

Parkinson’s disease Parkinson’s disease is a neurodegenerative disorder characterized by tremors, rigidity, bradykinesia, and postural instability. It does not cause meningeal irritation and thus does not present with Brudzinski's or Kernig’s signs.

Seizure disorder Seizure disorders involve abnormal electrical activity in the brain, leading to convulsions or other neurological symptoms. While seizures can occur in meningitis, the presence of Brudzinski's and Kernig’s signs specifically indicates meningeal irritation rather than a primary seizure disorder.

EXPLANATION

 

✔Correct answer:

Parkinson’s disease.  The symptoms of tremors and slow movements (bradykinesia) that Mr. Johnson exhibits are characteristic of Parkinson's disease. This neurological disorder is associated with the degeneration of dopamine-producing neurons in the substantia nigra, a region of the basal ganglia. The loss of these pigmented neurons leads to a reduction in dopamine levels, which is crucial for regulating smooth and coordinated muscle movements. Consequently, patients with Parkinson's disease often present with tremors, bradykinesia, rigidity, and postural instability.

Dopamine is a neurotransmitter that facilitates communication between the substantia nigra and other parts of the brain involved in movement control. In Parkinson’s disease, the progressive loss of dopaminergic neurons disrupts this communication, resulting in the motor symptoms observed. The substantia nigra, located in the midbrain, plays a key role in movement and coordination, and its degeneration is a hallmark of Parkinson’s disease.

Imagine a factory where dopamine acts as a lubricant for the machinery. When the lubricant runs out due to the degeneration of the machinery's supply system (the substantia nigra), the machines (muscles) move slowly, become stiff, and tremble.

Nurses managing patients with Parkinson's disease should focus on symptom management and maintaining the patient's quality of life.

• Monitor the patient's medication regimen, especially the administration of levodopa/carbidopa, which helps replenish dopamine levels and improve motor symptoms.
• Encourage regular physical activity and physical therapy to maintain muscle strength, flexibility, and balance.
• Provide education on safety measures to prevent falls, such as removing tripping hazards and using assistive devices as needed.
• Support the patient and family with resources and information on managing daily activities and coping with the disease's progression.
• Regularly assess the patient for non-motor symptoms, such as depression, sleep disturbances, and autonomic dysfunction, and coordinate appropriate interventions.

 

✘Incorrect answer options:

Multiple sclerosis. Multiple sclerosis (MS) is an autoimmune disorder that affects the central nervous system by damaging the myelin sheath of nerve fibers. While MS can cause a variety of neurological symptoms, including motor weakness and spasticity, it is not primarily associated with the specific combination of tremors, bradykinesia, and dopamine deficiency seen in Parkinson's disease.

Creutzfeldt-Jakob’s disease. Creutzfeldt-Jakob disease (CJD) is a rare, degenerative, and fatal brain disorder caused by prions. Symptoms include rapid mental deterioration, myoclonus (sudden muscle jerks), and ataxia (loss of coordination), but it does not typically involve the progressive loss of dopaminergic neurons characteristic of Parkinson's disease.

Huntington’s disease. Huntington's disease is a genetic disorder that causes the progressive breakdown of nerve cells in the brain. Symptoms include chorea (involuntary jerking or writhing movements), cognitive decline, and psychiatric symptoms. Unlike Parkinson's disease, Huntington's is not primarily associated with the loss of dopaminergic neurons in the substantia nigra.

EXPLANATION

 

✔Correct answer:

Parkinson’s disease. Parkinson’s disease is a progressive neurological disorder characterized by a variety of motor symptoms, including tremors, rigidity, bradykinesia (slowness of movement), and postural instability. One of the hallmark features of Parkinson’s disease is a shuffling gait, which is often described as short, dragging steps with reduced arm swing. This gait disturbance is due to the degeneration of dopamine-producing neurons in the substantia nigra, a part of the brain that plays a crucial role in movement control.

In Parkinson’s disease, the loss of dopamine-producing neurons leads to an imbalance between dopamine and acetylcholine in the basal ganglia. This imbalance disrupts the normal communication pathways that control and coordinate movement. As a result, individuals with Parkinson’s experience difficulty initiating and controlling voluntary movements, leading to the characteristic shuffling gait.

Imagine walking with heavy weights attached to your legs, making each step feel labored and causing you to take short, dragging steps. This simulates the difficulty that Parkinson’s patients face in initiating and sustaining smooth movements.

Nurses should focus on interventions that improve mobility and safety for patients with Parkinson’s disease.

• Encourage regular physical therapy and exercises designed to improve gait and balance.
• Assist patients with strategies such as using visual or auditory cues to initiate movement.
• Ensure the environment is free of obstacles and provide assistive devices as needed to prevent falls.
• Monitor for medication side effects and ensure adherence to prescribed dopaminergic therapies.
• Provide education and support to the patient and family about the progressive nature of the disease and available resources.

 

✘Incorrect answer options:

Multiple sclerosis Multiple sclerosis (MS) can cause a wide range of neurological symptoms, including muscle weakness, spasticity, and balance issues, but it does not typically present with a shuffling gait. Instead, MS gait disturbances are often characterized by spastic or ataxic movements due to demyelination in the central nervous system.

Raynaud’s disease Raynaud’s disease is a vascular condition that affects blood flow to extremities (usually fingers and toes), causing color changes, numbness, and pain in response to cold or stress. It is not associated with gait disturbances, as it primarily affects peripheral circulation rather than the central nervous system or musculoskeletal function.

Myasthenia gravis Myasthenia gravis is an autoimmune disorder that affects the neuromuscular junction, leading to muscle weakness and fatigue. While it can cause difficulty with movement and general muscle weakness, it does not typically result in a shuffling gait. Instead, symptoms are often characterized by fluctuating muscle strength, particularly in the eyes, face, and throat.

Occasionally lie in a prone position without using a neck pillow. For patients with Parkinson’s disease, maintaining a prone position (lying face down) without using a neck pillow can help counteract the forward flexion of the spine, which is commonly associated with the condition. This position encourages spinal extension and can help prevent the development of spinal curvatures and kyphosis (excessive curvature of the spine).

Parkinson’s disease often leads to postural changes, including a forward tilt of the trunk and a tendency to lean forward, which can contribute to spinal flexion deformities. By lying in a prone position, the spine is encouraged to extend, counteracting these flexion tendencies and helping to maintain a more natural alignment of the spine.

Imagine bending a flexible rod (your spine) forward consistently. Over time, it may stay bent. Occasionally laying it flat and gently pressing it backward can help it regain a straighter form.

Nurses should provide guidance on proper positioning and exercises to support spinal health and prevent deformities in patients with Parkinson’s disease.

• Encourage the patient to lie in a prone position periodically to stretch and extend the spine.
• Advise against using a neck pillow while in the prone position to avoid unnecessary neck flexion.
• Teach the patient about the importance of good posture and regular exercise to strengthen back muscles.
• Recommend physical therapy to develop a tailored exercise program that supports spinal health.
• Monitor for signs of spinal deformities and intervene early with appropriate strategies.

 

✘Incorrect answer options:

Rest in a supine position with his head elevated. Resting in a supine position with the head elevated may provide comfort but does not address spinal extension. In fact, it may promote forward flexion, contributing to spinal curvature over time.

Only sleep in the dorsal recumbent position. The dorsal recumbent position (lying on the back with the knees bent) does not specifically promote spinal extension and may not effectively counteract the flexion tendencies seen in Parkinson’s disease.

Sleep on either side but maintain a straight back. While sleeping on the side with a straight back can help maintain a neutral spine position, it does not actively promote spinal extension, which is necessary to counteract the forward flexion commonly seen in Parkinson’s disease.

✔Correct answer:

Mask-like facial expression.  In advanced Parkinson’s disease, patients often develop a mask-like facial expression. This is due to bradykinesia and rigidity affecting the muscles of the face, leading to a reduced ability to make facial expressions. The lack of facial expression, or hypomimia, is a hallmark sign of Parkinson's disease, especially in its later stages. This symptom results from the same underlying pathophysiology that affects other muscle groups in Parkinson’s disease—namely, the loss of dopamine-producing neurons in the substantia nigra and subsequent impaired motor control.

The facial muscles are affected by the same dopaminergic deficits that impact other muscles in the body in Parkinson's disease. Dopamine is crucial for smooth, coordinated muscle movements. When dopamine levels are low, as in Parkinson’s disease, muscle movements become slow and rigid, leading to the characteristic mask-like facial expression.

Imagine a puppet with strings that control its facial movements. If the strings are too tight or tangled, the puppet’s face can't move freely, resulting in a fixed expression. This is similar to how the facial muscles in a person with Parkinson's disease become rigid and slow-moving, leading to a mask-like appearance.

Nurses should be aware of the impact of mask-like facial expressions on communication and emotional expression in patients with advanced Parkinson’s disease.

• Use alternative communication methods, such as written or picture boards, if verbal communication becomes difficult.
• Be attentive to non-verbal cues and changes in the patient's condition that may not be easily expressed facially.
• Encourage facial exercises to maintain muscle tone and mobility.
• Provide emotional support and reassurance to patients and their families about the nature of the disease and its symptoms.
• Collaborate with speech and occupational therapists to develop strategies to improve communication and daily functioning.

 

✘Incorrect answer options:

Muscle atrophy. While muscle rigidity and bradykinesia are common in Parkinson’s disease, muscle atrophy is not a primary characteristic. Muscle atrophy typically results from disuse or neurological conditions that directly damage muscle tissue, which is not the case in Parkinson's disease.

Disturbed vision. Vision problems are not a primary symptom of Parkinson’s disease. Although some patients may experience visual disturbances due to other related conditions or side effects of medications, disturbed vision is not a defining feature of advanced Parkinson’s disease.

Forgetfulness. Cognitive impairment, including forgetfulness, can occur in Parkinson’s disease, particularly in its later stages, but it is not as distinctive a feature as the motor symptoms. Additionally, forgetfulness is more characteristic of conditions like Alzheimer’s disease. The motor symptoms, such as a mask-like facial expression, are more directly associated with Parkinson’s disease.

EXPLANATION

 

✔Correct answer:

Checking for orthostatic changes in pulse and blood pressure. Checking for orthostatic changes in pulse and blood pressure is a task that can be safely delegated to a nursing assistant (NA). This task involves measuring the patient's pulse and blood pressure while the patient is lying down, sitting, and standing. Nursing assistants are trained to perform these basic vital sign measurements, and this task does not require the advanced clinical judgment that is needed to interpret the results or make adjustments to the patient's care plan.

Think of a nursing assistant as a technician who can collect important data, like taking measurements and recording numbers, while the nurse is like an engineer who analyzes the data and makes decisions based on it.

Nurses can delegate the task of checking orthostatic vital signs to NAs, but they should ensure that NAs understand the procedure and the importance of accurately recording the measurements. The nurse should then review the data to interpret the findings and make clinical decisions.

• Provide clear instructions to the NA on how to properly measure and record orthostatic vital signs.
• Ensure the NA understands the importance of reporting any significant changes or symptoms experienced by the patient during the procedure.
• Review and interpret the measurements to assess for orthostatic hypotension or other issues.
• Educate the patient on how to safely change positions to minimize the risk of falls due to orthostatic hypotension.

 

✘Incorrect answer options:

Monitoring for improvement in tremor after levodopa (L-dopa) is given. Monitoring for changes in tremor after medication administration requires clinical judgment to assess the effectiveness of the medication and the patient's response. This task is within the scope of practice for a licensed nurse, not a nursing assistant.

Monitoring for abnormal involuntary jerky movements of extremities. Monitoring for abnormal involuntary movements, such as dyskinesias, also requires clinical assessment and judgment. Recognizing and interpreting these symptoms is a responsibility that falls under the purview of a licensed nurse.

Adjusting the dosage of levodopa (L-dopa) based on the patient’s response. Adjusting medication dosages is a complex task that requires advanced clinical knowledge and the authority to prescribe or alter medication regimens. This task is strictly within the domain of licensed healthcare providers, such as physicians or advanced practice nurses, and cannot be delegated to a nursing assistant.

EXPLANATION

 

✔Correct answer:

The occurrence of dyskinesia. Dyskinesia is a common adverse reaction associated with long-term use of carbidopa/levodopa (Sinemet) in patients with Parkinson’s disease. Dyskinesia refers to involuntary, erratic, and often excessive movements that can affect various parts of the body, such as the arms, legs, and face. This reaction occurs because levodopa, which converts to dopamine in the brain, can cause fluctuations in dopamine levels, leading to abnormal motor activity.

Carbidopa/levodopa is a combination medication where levodopa serves as a precursor to dopamine, and carbidopa inhibits the breakdown of levodopa before it reaches the brain, enhancing its effectiveness. Over time, as Parkinson’s disease progresses and the brain’s ability to regulate dopamine fluctuates, patients can develop dyskinesia as a side effect of the treatment.

Imagine a car with a fuel injection system (dopamine delivery in the brain) that needs precise amounts of fuel (levodopa) to run smoothly. Initially, the fuel is injected at the right intervals, and the car runs well. Over time, the system becomes erratic, sometimes injecting too much or too little fuel, causing the car to jerk and sputter unpredictably (dyskinesia). This irregularity in fuel delivery is similar to how fluctuating dopamine levels from long-term levodopa use can lead to involuntary movements in Parkinson’s patients.

To manage and monitor for dyskinesia, Nurse Parker should take the following steps:

• Regularly assess the patient’s motor function and document any involuntary movements.
• Educate the patient and caregivers about recognizing dyskinesia and its potential impact on daily activities.
• Collaborate with the healthcare provider to adjust the medication dosage or schedule if dyskinesia becomes problematic.
• Consider other therapeutic options, such as deep brain stimulation or alternative medications, if dyskinesia significantly impacts quality of life.
• Encourage the patient to maintain a log of symptoms and medication effects to assist in fine-tuning the treatment plan.

 

✘Incorrect answer options:

The onset of glaucoma. While levodopa/carbidopa can potentially increase intraocular pressure, it is not a common or primary adverse effect. Monitoring for glaucoma is essential, but it is not as directly related to the medication as dyskinesia.

The development of a rash or other signs of an allergic reaction. Allergic reactions are possible with any medication, but they are not a common or specific concern with carbidopa/levodopa. Dyskinesia is a more prevalent and significant side effect for this medication.

The emergence of respiratory depression. Respiratory depression is not typically associated with carbidopa/levodopa. This adverse effect is more commonly linked to opioid medications or sedatives, not Parkinson’s disease treatments.

EXPLANATION

 

✔Correct answer:

Ensuring the client sits in an upright position while eating. For clients with Parkinson’s disease, sitting in an upright position while eating is crucial for safe swallowing and effective nutrition. This position helps prevent aspiration, which is the inhalation of food or liquids into the lungs, and facilitates the natural movement of food through the esophagus into the stomach.

Parkinson’s disease often affects muscle control, including the muscles involved in swallowing (dysphagia). An upright position allows gravity to assist with the passage of food and liquids, reduces the risk of choking, and helps maintain an open airway, thereby minimizing the risk of aspiration pneumonia, a common complication in Parkinson’s patients.

Think of trying to pour water through a tilted funnel versus one held straight up. The straight funnel (upright position) allows the water to flow smoothly without spilling (aspiration), while the tilted funnel (reclined position) causes the water to spill out the sides.

To support effective swallowing and proper nutrition in Parkinson’s disease patients, nurses should implement specific strategies tailored to their needs.

• Ensure the client is seated upright, preferably at a 90-degree angle, during meals and for at least 30 minutes afterward.
• Provide small, frequent meals that are easier to manage and less tiring for the client to eat.
• Encourage thorough chewing and slower eating to prevent choking and improve digestion.
• Modify food textures to soft or pureed if necessary, to facilitate easier swallowing.
• Collaborate with a speech therapist for a swallowing evaluation and additional techniques to enhance safe eating.

 

✘Incorrect answer options:

Personally feeding the client. While assisting the client with feeding may be necessary in advanced stages or if the client has significant motor impairments, it is more beneficial to promote independence as much as possible. Ensuring the correct posture is more crucial for safe swallowing than feeding the client directly.

Encouraging the intake of solid foods. Solid foods can pose a choking hazard for individuals with dysphagia. It is important to assess the client’s ability to chew and swallow different food textures and modify the diet accordingly to ensure safety and nutritional adequacy.

Providing liquids during meals. Providing liquids during meals can sometimes increase the risk of aspiration, especially if the client has difficulty coordinating swallowing with breathing. Thickened liquids or careful monitoring of liquid intake may be necessary, depending on the severity of the dysphagia.

EXPLANATION

 

✔Correct answer:

It increases the availability of dopamine. Levodopa is a precursor to dopamine and is the most effective medication for managing the symptoms of Parkinson’s Disease. Once administered, levodopa crosses the blood-brain barrier and is converted into dopamine in the brain. This conversion helps replenish the diminished dopamine levels, thereby improving the motor symptoms associated with Parkinson’s Disease, such as tremors, bradykinesia, rigidity, and postural instability.

Parkinson’s Disease is characterized by the degeneration of dopamine-producing neurons in the substantia nigra, leading to a significant reduction in dopamine levels in the brain. Dopamine is essential for coordinating smooth and voluntary muscle movements. By increasing the availability of dopamine through the administration of levodopa, the medication helps restore more normal function to the basal ganglia, thereby improving motor control.

Imagine a car with a nearly empty gas tank struggling to move smoothly. Levodopa acts like a fuel refill for the car (brain), allowing it to run more efficiently and perform its functions better.

Nurses managing patients on levodopa should monitor for both the therapeutic effects and potential side effects of the medication.

• Assess the patient’s motor symptoms regularly to evaluate the effectiveness of the medication.
• Monitor for common side effects of levodopa, such as nausea, dizziness, orthostatic hypotension, and dyskinesias (involuntary movements).
• Educate the patient on the importance of taking the medication on a consistent schedule and not with high-protein meals, which can interfere with the absorption of levodopa.
• Encourage the patient to report any new or worsening symptoms, as the medication regimen may need adjustment.
• Support the patient with strategies to manage any side effects and ensure they understand the role of levodopa in managing their condition.

 

✘Incorrect answer options:

It decreases the availability of acetylcholine. While the balance between dopamine and acetylcholine is important in Parkinson’s Disease, levodopa specifically increases dopamine levels rather than directly affecting acetylcholine availability.

It activates dopaminergic receptors in the basal ganglia. Levodopa itself does not directly activate dopaminergic receptors. Instead, it is converted into dopamine in the brain, which then activates these receptors. Dopamine agonists, such as pramipexole or ropinirole, directly stimulate dopaminergic receptors.

It releases dopamine and other catecholamines from neurological storage sites. Levodopa does not release dopamine from storage sites; it is a precursor that is converted into dopamine after crossing the blood-brain barrier. The primary goal is to increase dopamine synthesis rather than release stored dopamine.

EXPLANATION

 

✔Correct answer:

"Using a cane might provide you with the additional support you need while walking." For a 66-year-old woman with Parkinson's Disease experiencing difficulty walking, the use of a cane is a practical and effective suggestion. Parkinson's Disease often leads to symptoms such as bradykinesia (slowness of movement), rigidity, and balance issues, which can make walking challenging and increase the risk of falls. A cane can provide additional support and stability, helping to reduce these risks and promote safer mobility.

Parkinson's Disease affects the basal ganglia in the brain, which play a critical role in coordinating movement. The loss of dopamine-producing neurons in this area leads to motor symptoms such as tremors, rigidity, and bradykinesia. These symptoms can significantly impair a person's ability to walk and maintain balance.

Think of walking with Parkinson's Disease like trying to walk on a very slippery surface. A cane acts like a safety rail, giving you something to hold onto for extra support and helping prevent you from slipping and falling.

When advising the use of a cane, nurses should ensure the patient is properly educated on how to use it correctly to maximize its benefits.

• Ensure the cane is adjusted to the correct height for the patient to avoid strain.
• Instruct the patient on how to hold the cane on the stronger side of their body and move it simultaneously with the weaker leg.
• Encourage practice in a safe environment to build confidence in using the cane.
• Monitor the patient for any signs of discomfort or improper use, and provide feedback as needed.
• Reassure the patient that using a cane is a positive step towards maintaining their independence and safety.

 

✘Incorrect answer options:

"Focus on walking at a steady, comfortable pace to maintain your mobility." While maintaining a steady pace is generally good advice, it does not address the immediate need for support in a patient with Parkinson's Disease who is already experiencing difficulty walking. This suggestion alone might not be sufficient to ensure her safety and could lead to falls if additional support is not provided.

"I can arrange for a wheelchair to help ensure your safety and comfort." Offering a wheelchair might be necessary in some cases, but it could be premature and might reduce the patient's mobility and independence unnecessarily. A cane or walker is often a more appropriate first step in providing support while still encouraging the patient to walk.

"If walking becomes too challenging, it's important not to push yourself too hard." Advising the patient not to push herself too hard is valid, but it lacks a practical solution to her current mobility issue. Encouraging the use of a cane provides a proactive approach to improve her walking ability safely.

EXPLANATION

 

✔Correct answer:

Multiple sclerosis. Multiple sclerosis (MS) is a chronic, degenerative, and progressive disease of the central nervous system (CNS) characterized by the presence of small patches of demyelination in the brain and spinal cord. Demyelination refers to the damage or loss of the myelin sheath, which is the protective covering that surrounds nerve fibers. This disruption in myelin impairs the ability of nerves to conduct electrical impulses, leading to a wide range of neurological symptoms.

In multiple sclerosis, the immune system mistakenly attacks the myelin sheath in the CNS. This leads to the formation of scar tissue (sclerosis) and disrupts communication between the brain and the rest of the body. Symptoms of MS can include fatigue, difficulty walking, numbness or tingling, muscle weakness, and problems with coordination and balance.

Think of the myelin sheath as the insulation around electrical wires. In multiple sclerosis, this insulation is damaged, causing short circuits in the electrical system (nervous system), leading to various malfunctions (symptoms).

Managing MS involves addressing symptoms, preventing relapses, and maintaining quality of life. Nurses play a key role in providing care and support to patients with MS.

• Administer disease-modifying therapies (DMTs) to slow disease progression and reduce relapse frequency.
• Implement strategies to manage symptoms such as fatigue, spasticity, and pain.
• Encourage regular physical activity and rehabilitation exercises to maintain mobility and function.
• Provide education and support to help patients cope with the emotional and psychological impact of MS.
• Monitor for potential complications such as infections or pressure ulcers due to immobility.

 

✘Incorrect answer options:

Creutzfeldt-Jakob’s disease Creutzfeldt-Jakob’s disease (CJD) is a rare, degenerative, and fatal brain disorder caused by prion proteins. It leads to rapid mental deterioration, movement problems, and dementia, but it is not characterized by demyelination.

Huntington’s disease Huntington’s disease is a genetic disorder that causes the progressive breakdown of nerve cells in the brain. It leads to movement, cognitive, and psychiatric disorders. Huntington’s disease does not involve demyelination; instead, it is characterized by the loss of neurons in certain areas of the brain.

Parkinson’s disease Parkinson’s disease is a neurodegenerative disorder that primarily affects movement. It is caused by the degeneration of dopamine-producing neurons in the brain. Symptoms include tremors, stiffness, and bradykinesia (slowness of movement), but it does not involve demyelination of the CNS.
