Answers and Rationale

1. Answer: C. Viral load test. A viral load test helps provide information on the health status and how well antiretroviral therapy (ART – treatment with HIV medicines) is controlling the virus.

  • Options A and B monitors the presence of antibodies to HIV, so these tests will yield a positive result after the patient is infected with HIV even if the drug therapy is effective.
  • Option D will be used to assess the impact of HIV on immune function but will not directly measure the effectiveness of the medicines.

2. Answer: B. Complete blood count. Zidovudine may decrease the number of a certain type of white blood cell in the blood and cause anemia and muscle disorders.

  • Options A, C, and D are not related to the medication.

3. Answer: D. Avoid being exposed to sunlight. Saquinavir (Invirase) is an antiviral medicine that prevents human immunodeficiency virus (HIV) from multiplying in the body. This can cause photosensitivity so the nurse should instruct the client to avoid sun exposure.

  • Option A: The medicine is taken with food or within 2 hours after eating a full meal.
  • Option B: The medicine is best absorbed with a high-fat meal.
  • Option C: Weight loss instead is expected.

4. Answer: D. Gait. One of the most serious side effects of Stavudine (Zerit) is peripheral neuropathy so the nurse should monitor the client’s gait while taking this medication.

  • Options A, B, and C are not related to the use of the medication.

5. Answer: C. Sudden sweating and hunger. Pentamidine can cause fatal hypoglycemia, so symptoms such as sudden sweating and hunger are indicative of a low blood sugar indicates a need for change in the treatment.

  • Option A: A low blood pressure may indicate the need of a slower infusion.
  • Option B: Redness and Pain is a sign for the nurse to establish a new IV line.
  • Option D: Dryness and unusual taste may happen at the start but do not need for an immediate notification of the physician.

6. Answer: C. The client has developed another infection. Pentamidine can cause low white blood cells or low platelets in your blood, so the client is most likely developed another infection brought about these side effects.

  • Options A, B, and D are inappropriate interpretation.

7. Answer: A. Do a 12-lead ECG. Pentamidine may cause a condition that affects the heart rhythm (QT prolongation). QT prolongation can rarely cause serious fast/irregular heartbeat and other symptoms (such as severe dizziness, fainting) that need an urgent medical attention.

  • Options B and D are not related to the use of the medication.
  • Option C: Low levels of potassium in the blood can increase the risk of QT prolongation.

8. Answer: D. Blood pressure. Hypertension is one of the side effects of taking cyclosporine (Neoral) and since the client is also complaining of sweating and headache, the blood pressure is the important sign to be monitored closely.

9. Answer: A. The client has a soft non-tender lump in the shoulder. A client taking immunosuppressive medications are at risk for development of cancer. A soft non-tender lump will indicate that the patient has lymphoma.

  • Options B, C, and D are common side effects of the immunosuppressive medications.

10. Answer: B. Albuterol (Ventolin HFA). Albuterol (Ventolin HFA) is the most rapidly acting of the medications among the choices.

  • Option A is not the first line treatment for a bronchospasm.
  • Options C and D are corticosteroids that are used during allergic reaction but are not rapidly acting.

11. Answer: D. Serum sodium. Renal impairment is the major toxicity involve in Foscarnet (Foscavir); This medicine also may cause decreased levels of calcium, magnesium, phosphorous, and potassium.

12. Answer: B. Efavirenz. Efavirenz is a non-nucleoside reverse transcriptase inhibitor. Side effects include rash, dizziness, confusion, headache, and nightmares.

  • Options A and C: Lamivudine and Tenofovir side effects includes headache, dizziness, nausea, diarrhea, or trouble sleeping.
  • Option D: Saquinavir can cause headache, nausea, diarrhea, and photosensitivity.

13. Answer: D. Elevated triglyceride level. Sirolimus (Rapamune) raises cholesterol and triglyceride levels. This medication also causes a decrease in potassium and platelet count.

14. Answer: D. “Do not receive any live vaccinations while on this treatment”. Tacrolimus may lower your body’s resistance and the vaccine may not work as well or the client may get the infection the vaccine is meant to prevent.

15. Answer: A. Insomnia. These medications can cause diarrhea, vomiting, sepsis, back pain, neutropenia and hypertension.

16. Answer: D. Hearing loss. Amikacin is an aminoglycoside. Side effects of this medication includes ototoxicity (Hearing loss), confusion, disorientation, gastrointestinal irritation, palpitations, blood pressure changes and nephrotoxicity.

  • Options A, B, and C are not related with the medication.

17. Answer: D. Pseudomembranous colitis. Pseudomembranous colitis also called antibiotic-associated colitis or C. difficile colitis, is the inflammation of the colon associated with an overgrowth of the bacterium Clostridium difficile. This overgrowth of C. difficile is most often related to recent antibiotic use such as ampicillin, clindamycin, fluoroquinolones, and cephalosporins.

  • Options A, B, and C may have the symptoms of the client but are not likely due to this case.

18. Answer: B. Ketoconazole. Azole antifungals (eg, ketoconazole) decreases the effectiveness of amphotericin b.

  • Options A and C: Fever, shaking, chills, flushing, loss of appetite, dizziness, nausea, vomiting, headache, shortness of breath, or fast breathing may occur 1 to 3 hours after the infusion is started. Medications such as acetaminophen, diphenhydramine, corticosteroids such as hydrocortisone) may be necessary to prevent these side effects.
  • Option D: Meperidine (25 to 50 mg IV) has been shown in some patients to decrease the duration of shaking chills and fever that may accompany the infusion of amphotericin B.

19. Answer: A. Report any history of tendon problems. Ciprofloxacin may cause swelling or tearing of a tendon (the fiber that connects bones to muscles in the body), especially in the Achilles’ tendon of the heel. This can happen during treatment or up to several months after the client stop taking ciprofloxacin

  • Option B: This medication can cause dizziness so avoid any activity that requires alertness until the client is sure to perform such activities safely.
  • Option C: Take ciprofloxacin at least 2 hours before or 6 hours after taking an antacid.
  • Option D: Eating dairy products such as yogurt will impair the effectiveness of ciprofloxacin.

20. Answer: A. Glossitis., D. Discoloration of the nails., E. Photosensitivity. Side effects of tetracycline include glossitis, discoloration of the nails, photosensitivity,  anorexia, nausea, vomiting, diarrhea, bulky loose stools, stomatitis, sore throat, black hairy tongue,dysphagia,and hoarseness.
