1. A nursing student is learning about the effects of bactericidal agents. How does rifampin (Rifadin) achieve a therapeutic action against both intracellular and extracellular tuberculosis organisms?

Correct answer: C

Rationale: Rifampin (Rifadin) achieves a therapeutic action against both intracellular and extracellular tuberculosis organisms by inhibiting the synthesis of RNA. This action interferes with bacterial RNA synthesis, leading to the suppression of protein synthesis in the bacteria, ultimately causing their death. Option A is incorrect because rifampin is primarily metabolized in the liver, but this is not how it exerts its bactericidal effects. Option B is incorrect as rifampin does not bind to acetylcholine. Option D is also incorrect as rifampin does not cause phagocytosis.

2. A patient began antiretroviral therapy several weeks ago for the treatment of HIV, and he has now presented to the clinic for a scheduled follow-up appointment. He states to the nurse, “I've been pretty good about taking all my pills on time, though it was a bit hit and miss over the holiday weekend.” How should the nurse best respond to this patient's statement?

Correct answer: C

Rationale: The correct response is to remind the patient that antiretroviral drugs are most effective when taken consistently and as prescribed. Choice A is incorrect because taking a double dose after missing a dose is not recommended, as it can lead to medication toxicity. Choice B is incorrect as it may give the impression that missing doses is acceptable, which can reduce the effectiveness of the treatment. Choice D is incorrect because while consistency is important, the focus should be on treatment effectiveness rather than side effects.

3. If the client's dorsal columns are not functioning, the nurse will observe which response during neuro testing, where the nurse asks the client to close his eyes and then proceeds to touch corresponding parts of the body on each side simultaneously with two sharp points?

Correct answer: A

Rationale: If the client's dorsal columns are not functioning, the ability to distinguish between two closely spaced points is impaired. This results in the client not being able to differentiate between the two points when touched simultaneously. Choice B is incorrect because the client feeling only one point suggests an intact dorsal column function. Choice C is incorrect as accurately identifying both points indicates normal discrimination ability. Choice D is incorrect as reporting no sensation does not correspond to the specific impairment related to dorsal column dysfunction.

4. On the advice of his brother, a 53-year-old man has made an appointment to request a prescription for Viagra. The nurse who works at the clinic is reviewing the man's medical history and would recognize what health problem as being prohibitive to this treatment?

Correct answer: C

Rationale: Nitroglycerin is contraindicated with Viagra due to their combined effects on lowering blood pressure, which can result in a severe drop and potentially life-threatening complications. Using both medications together can lead to hypotension, putting the patient at risk. Therefore, the presence of angina treated with nitroglycerin would make prescribing Viagra unsafe. Choices A, B, and D are not directly contraindicated with Viagra and can be managed concurrently with this treatment.

5. A patient is receiving epoetin alfa (Epogen) for anemia. Which of the following adjunctive therapies is imperative with epoetin alfa?

Correct answer: C

Rationale: The correct answer is C: Iron supplement. When a patient is receiving epoetin alfa for anemia, it is imperative to provide iron supplementation as epoetin alfa works by stimulating the production of red blood cells, which require iron for hemoglobin synthesis. Therefore, iron supplementation is crucial to support the increased erythropoiesis. Choices A, B, and D are incorrect because potassium supplements, sodium restriction, and renal dialysis are not typically indicated as adjunctive therapies with epoetin alfa for anemia.
