LPN Pharmacology Questions Questions
Question 1 of 5
A patient will begin taking two drugs that are both protein-bound. The primary care NP should:
Correct Answer: B
Rationale: The correct answer is B because protein-bound drugs compete for albumin, requiring monitoring to adjust dosing.
Choice A is incorrect as increasing doses without monitoring is risky.
Choice C is wrong since dietary protein doesn’t affect this.
Choice D is inaccurate as staggering doesn’t resolve binding issues.
Question 2 of 5
A patient has been taking trimethoprim-sulfamethoxazole (TMP/SMX) for 14 days. The patient calls the primary care nurse practitioner (NP) to report fever, rash, and enlarged lymph nodes. The NP should suspect:
Correct Answer: A
Rationale: The correct answer is A because serum sickness (fever, rash, lymphadenopathy) occurs days to weeks after TMP/SMX.
Choice B is incorrect (immediate within 30 minutes).
Choice C is wrong (blood-related, 7-14 days).
Choice D is inaccurate (rash syndromes, 48-72 hours).
Question 3 of 5
An NP learns that a 90-year-old patient is chronically constipated and has frequent problems with acid reflux. The NP notes a weight loss of 20 pounds in the previous 6 months. Which of the following drugs that this patient is taking is cause for concern?
Correct Answer: B
Rationale: The correct answer is B because naproxen, highly protein-bound, can become toxic with low albumin from malnutrition, as seen in this patient’s weight loss.
Choice A is incorrect as quinidine isn’t primarily protein-bound related.
Choice C is wrong since calcium citrate isn’t affected this way.
Choice D is inaccurate as calcium channel blockers have different concerns.
Question 4 of 5
A client has a new prescription for enalapril. Which of the following instructions should the nurse include?
Correct Answer: A
Rationale: The correct answer is A: Monitor for a dry cough. When a client is prescribed enalapril, it is important to monitor for a dry cough because it can be a side effect that indicates a potential issue like angioedema. This side effect needs close attention as it may require discontinuation of the medication to prevent further complications.
Choices B, C, and D are incorrect because enalapril does not need to be taken at bedtime, does not interact with grapefruit juice, and can be taken without regard to meals.
Question 5 of 5
Strategies to prevent drug abuse include:
Correct Answer: D
Rationale:
Choice D is correct because education (awareness), access limits (e.g., PDMPs), and screening (early intervention) all prevent abuse, per public health strategies.
Choice A is incorrect alone as it's one method.
Choice B is wrong by itself because access is just part.
Choice C is incorrect solo since screening is only one approach.
