1. A client has a new prescription for a combination of oral NRTIs (abacavir, lamivudine, and zidovudine) for the treatment of HIV. Which of the following statements should the nurse include in teaching the client?
- A. These medications work by blocking HIV entry into cells.
- B. These medications work by weakening the cell wall of the HIV virus.
- C. These medications work by inhibiting enzymes to prevent HIV replication.
- D. These medications work by preventing protein synthesis within the HIV cell.
Correct answer: C
Rationale: The NRTI antiretroviral medications this client is prescribed work by inhibiting the enzyme reverse transcriptase, thus preventing HIV replication. By inhibiting this crucial enzyme, the drug interferes with the virus's ability to replicate and spread in the body. Choice A is incorrect because NRTIs do not block HIV entry into cells. Choice B is incorrect as NRTIs do not weaken the cell wall of the virus. Choice D is incorrect as NRTIs do not prevent protein synthesis within the HIV cell.
2. Which medication is contraindicated with Nitroglycerin?
- A. Hydrochloroquine
- B. Methylprednisolone
- C. Phenazopyridine
- D. Erectile dysfunction drugs
Correct answer: D
Rationale: The correct answer is D: Erectile dysfunction drugs. Erectile dysfunction drugs are contraindicated with Nitroglycerin because they can potentiate the hypotensive effects of Nitroglycerin, leading to severe hypotension. Choices A, B, and C are incorrect because they are not known to have significant interactions with Nitroglycerin.
3. A healthcare provider is caring for a client who is prescribed Furosemide. Which of the following laboratory values should the healthcare provider monitor?
- A. Serum potassium
- B. Serum calcium
- C. Serum sodium
- D. Serum magnesium
Correct answer: A
Rationale: Furosemide is a loop diuretic that can cause hypokalemia (low potassium levels) due to increased potassium excretion in the urine. Monitoring serum potassium levels is crucial to prevent complications such as cardiac arrhythmias. Therefore, the healthcare provider should closely monitor the client's serum potassium levels when they are prescribed Furosemide. While monitoring other electrolytes like sodium and magnesium may also be important in certain situations, the priority for a client prescribed Furosemide is to monitor serum potassium levels due to the risk of hypokalemia.
4. A nurse is assessing a client who is receiving IV vancomycin. The nurse notes a flushing of the neck and tachycardia. Which of the following actions should the nurse take?
- A. Document that the client experienced an anaphylactic reaction to the medication.
- B. Change the IV infusion site.
- C. Decrease the infusion rate on the IV.
- D. Apply cold compresses to the neck area.
Correct answer: C
Rationale: Flushing and tachycardia are signs of Red Man Syndrome, which can be mitigated by decreasing the infusion rate.
5. A client is undergoing preparation for extensive colorectal surgery. Which of the following oral antibiotics should be administered to suppress normal flora in the GI tract?
- A. Kanamycin
- B. Gentamicin
- C. Neomycin
- D. Tobramycin
Correct answer: C
Rationale: The correct answer is C: Neomycin. Neomycin, an aminoglycoside antibiotic, is administered orally before GI surgery to eliminate the normal flora in the large intestine. This helps reduce the risk of postoperative infections by decreasing the bacterial load in the gut. Choices A, B, and D (Kanamycin, Gentamicin, Tobramycin) are not typically used to suppress normal flora in the GI tract before colorectal surgery.
