LPN Pharmacology Practice Questions Questions
Question 1 of 5
Reasons for restricted distribution of drugs include:
Correct Answer: B
Rationale:
Choice B is correct because restricted distribution (e.g., REMS) is primarily for drugs with serious safety risks (e.g., thalidomide), not cost or supply alone.
Choice A is incorrect as cost doesn't mandate restriction—insurance handles that.
Choice C is wrong because limited supply isn't a REMS trigger.
Choice D is incorrect since only B is the core reason.
Question 2 of 5
A client with chronic obstructive pulmonary disease (COPD) is prescribed theophylline. Which adverse effect should the nurse monitor for that indicates toxicity?
Correct Answer: A
Rationale: The correct answer is A: Tachycardia. Tachycardia is a common sign of theophylline toxicity. The nurse should monitor the client for an increased heart rate, as it can indicate a dangerous level of theophylline in the body. Prompt medical attention is required if tachycardia is observed to prevent further complications.
Choices B, C, and D are incorrect because constipation, drowsiness, and tremors are not typically associated with theophylline toxicity. While theophylline can cause gastrointestinal upset or central nervous system effects, tachycardia is a more specific and serious indicator of toxicity that requires immediate attention.
Question 3 of 5
A woman who is pregnant develops gestational diabetes. The NP's initial action is to:
Correct Answer: B
Rationale: The correct answer is B because diet and exercise are the initial management for gestational diabetes.
Choice A is incorrect (oral agents lack sufficient safety data).
Choice C is wrong (insulin isn’t first-line).
Choice D is inaccurate (reassurance alone doesn’t address current needs).
Question 4 of 5
When determining drug treatment, the NP prescriber should:
Correct Answer: B
Rationale:
Choice B is correct because tailoring treatment to the patient's unique factors—age, comorbidities, preferences—optimizes efficacy and safety.
Choice A is incorrect as guidelines inform but don't dictate every case.
Choice C is wrong because experience alone may lack evidence support.
Choice D is incorrect since newest drugs aren't always best—evidence and patient fit matter more.
Question 5 of 5
Phase IV clinical trials in the United States are also known as:
Correct Answer: B
Rationale:
Choice B is correct because phase IV trials occur after drug approval, monitoring long-term effects and safety in the general population, known as post-marketing research.
Choice A is incorrect as bioavailability is studied earlier, like phase I.
Choice C is wrong because safety and efficacy are pre-approval (phases I-III).
Choice D is incorrect since phase IV isn't animal-based—it's post-approval human study.
