Answers and Rationale
  1. Answer: A. Cholinergic agents. Cholinergic drugs mimic the effects of the parasympathetic nervous system. Anticholinergic agents antagonize the parasympathetic nervous system. Adrenergic agents stimulate sympathetic nervous system. Antiadrenergic agents block the effect of the sympathetic nervous system.
  2. Answer: A. Produce miosis. Miosis is a parasympathetic activity and is therefore the correct choice. B, C and D are incorrect because cholinergic agents are antidotes to neuromuscular blockers and tricyclic antidepressants.
  3. Answer: D. Asthma. Bronchial asthma is a contraindication of cholinergics because administration of cholinergics will cause bronchoconstriction.
  4. Answer: C. Adrenergics. Drugs that mimic the effects of sympathetic activity are known as adrenergics.
  5. Answer: C. Hyperglycemia. A, B, and D are incorrect because the effects of insulin are antagonized by adrenaline or adrenergic agents.
  6. Answer: D. Obstructive airway disease. Adrenergic blockers tend to cause bronchoconstriction, so are therefore contraindicated in obstructive pulmonary disease.
  7. Answer: D. All of the above. Cholinergic drugs increase GI activity, causing all of these side effects.
  8. Answer: A. methylphenidate (Ritalin). Methylphenidate (Ritalin) is the drug of choice for attention deficit disorder. B and C are commonly used for exogenous obesity. Caffeine is a mild CNS stimulant that is not used for attention deficit disorder.
  9. Answer: D. Enhance performance. Drugs that produce a desired effect, such as feelings of euphoria and improved performance, tend to be overused and abused. Nervousness, decreased weight, and increased blood pressure are all effects of amphetamine. However, they are considered drugs of abuse because of their ability to enhance performance and produce a euphoric effect.
  10. Answer: B. Antidiabetic agents. Antidiabetic agents tend to decrease the effectiveness of amphetamines. A and C increase the effects of amphetamines.
  11. Answer: C. MAO inhibitors. MAO inhibitors must never be given with drugs affecting the CNS because hypertension can occur. Amphetamines can be given with oral hypoglycemics and insulin as long as blood sugar levels are monitored because these can decrease antidiabetic requirements.
  12. Answer: D. A and B. Use of Ritalin does not cause a growth spurt. Instead, it can cause Tourette’s syndrome and growth suppression in children.
  13. Answer: D. All of the above. The most common uses of amphetamines and amphetamine-like compounds are narcolepsy, exogenous obesity, and attention deficit disorder.
  14. Answer: D. Mix the drug in saline solution. Phenytoin must be mixed in saline solution only. Phenytoin should be administered at a rate of 50 mg/min. There is no need to protect phenytoin from light because it does not destabilize with light exposure. Phenytoin will precipitate when mixed with a dextrose solution.
  15. Answer: A. Decreased effectiveness of warfarin. The interaction will reduce the effectiveness of warfarin.
  16. Answer: C. Activating dopamine receptors in the brain. Bromocriptine is a dopaminergic agent, and this response refers to its action. Choice A refers to the action of levodopa. Choice B refers to the action of carbidopa and levodopa. Choice D refers to the action of selegiline.
  17. Answer: B. “I had to take Dilantin 6 months ago.”. Amantadine is used cautiously in clients with a history of seizures. A and D are clinical manifestations of Parkinson’s disease. Amantadine does not interact negatively with aspirin.
  18. Answer: A. Monitor the pulse for rate and regularity. Dopaminergic agents can cause heart rate changes and cardiac arrhythmias. Choice B is incorrect because amantadine can cause insomnia. Choice C is incorrect because an adverse effect of amantadine is a mottled discoloration of the skin. Choice D is incorrect because dry mouth is an expected side effect and not an indication to discontinue amantadine.
  19. Answer: A. Date of birth. Antimuscarinic agents are contraindicated in elderly patients.
  20. Answer: C. Decreased tremors at rest. Carbidopa and levodopa help restore the balance between dopamine and acetylcholine, thereby controlling the responses of Parkinson’s disease.
  21. Answer: C. Parkinson’s disease. Benzodiazepines may exacerbate the symptoms of Parkinson’s disease.
  22. Answer: D. Implement a fall prevention protocol. Increased sedation, dizziness, and hypotension are side effects that place the elderly at high risk for falls. All clients need to have vital signs monitored periodically when taking these medications. Geriatric clients may require reduced doses, but the risk for falls is still present. Dose tapering is not related to age.
  23. Answer: C. Ataxia, sedation, dizziness. These are common side effects. Anorexia is a GI effect. Choice B are the result of acute withdrawal. Libido and edema are not CNS-related side effects.
  24. Answer: D. Changing the availability of select neurotransmitters. This choice best describes the effect of antidepressants in general.
  25. Answer: D. Inform the physician of the client’s history before administering the TCA. Narrow-angle glaucoma is a contraindication for use of TCAs; therefore, the physician should be informed so that an alternative category can be used.
  26. Answer: A. For treatment of Tourette’s syndrome. Haloperidol (Haldol) is used for this syndrome. Major depression is an affective disorder. When psychotic symptoms accompany depression, antipsychotics may be used to manage the symptoms. However, this choice does not address that situation. Antipsychotics are used with caution in the presence of a history of seizures. Generally, the antipsychotics decrease the seizure threshold. Antipsychotics are used to ameliorate, reduce, or manage psychotic symptoms; they do not provide a cure.
  27. Answer: C. It is too early to see a full therapeutic response. The initial response may be seen 1 to 2 days after initiation of treatment, with full therapeutic response in approximately 6 to 8 weeks.
  28. Answer: B. Encourage the client to follow a healthy diet and use diet soda to help stabilize her weight. These agents have a known side effect of weight gain. Managing dietary intake can assist in the management of the potentially distressing effect.
  29. Answer: A. Spasm due to trauma or inflammation. Centrally acting skeletal muscle relaxants are most effective in relieving spasm due to trauma or inflammation.
  30. Answer: D. As adjuncts to general anesthesia. Peripherally acting skeletal muscle relaxants are used as an adjunct to general anesthesia.
  31. Answer: A. Early in the morning. Fluoxetine is used to treat major depressive disorder, bulimia nervosa  obsessive-compulsive disorder, panic disorder, and premenstrual dysphoric disorder (PMDD). It is taken early in the morning to prevent interference with sleep.
  32. Answer: B. Muscle rigidity and high fever. Serotonin syndrome symptoms include high body temperature, agitation, muscle rigidity, tremor, sweating, dilated pupils, and diarrhea.
  33. Answer: A. Suicidal thoughts. Clients may have thoughts about suicide when taking an antidepressant such as amitriptyline, especially clients younger than 24 years old.
    • Options B, C, and D are signs of depressions but are most likely improved as the treatment goes on.
  34. Answer: D. At bedtime. Sertraline (Zoloft) is an antidepressant. It may be administered in the morning or evening, but giving it in the evening is more favored since drowsiness is one of the side effects.
  35. Answer: E. Administration of an antipyretic. One of the signs and symptoms of a tricyclic antidepressant overdose is hypothermia, so an administration of an antipyretic will not help in the treatment.

    • Options A, B, and D are not side effects related to the medication.
  38. Answer: D. Yogurt. Phenelzine (Nardil) is a monoamine oxidase (MAO) inhibitor. The client should avoid eating tyramine-rich foods such as chocolate, alcoholic beverages, aged cheese, yogurt, processed meats, and fruits such as raisins, avocados, bananas, or figs.
  39. Answer: B. Diplopia. Monoamine Oxidase Inhibitor Toxicity symptoms include hypertension, tachycardia, diplopia, nausea, dilated pupils, palpitations, constricting chest pain and altered mental status.
    • Options A and C are a common side effect of monoamine oxidase inhibitor.
    • Option D is not a related symptoms of hypertensive crisis.
  40. Answer: C. Phentolamine. In a hypertensive emergency, the first goal is to bring down the blood pressure as quickly as possible with intravenous (IV) blood pressure medications to prevent further organ damage. Phentolamine Mesylate (phentolamine mesylate) is used as an antidote for a hypertensive crisis.
    • Option A: Lithium citrate is a mood stabilizer.
    • Option C: Diazepam is a benzodiazpepines.
