LPN Pharmacology Practice Questions Questions
Question 1 of 5
A client has a new prescription for docusate sodium. Which of the following instructions should be included in the discharge teaching?
Correct Answer: A
Rationale: Corrected Rationale: When taking docusate sodium, it is important to take the medication with a full glass of water to help ensure its proper effectiveness. This helps prevent the stool from hardening and makes it easier to pass, especially for individuals experiencing constipation. Choice B is incorrect because there is no specific instruction to take docusate sodium at bedtime. Choice C is incorrect because docusate sodium does not need to be taken on an empty stomach. Choice D is incorrect because there is no need to avoid taking docusate sodium with antacids.
Question 2 of 5
While assessing a client taking propranolol, which finding should the nurse report to the provider?
Correct Answer: A
Rationale: Bradycardia is a significant side effect of propranolol, a beta-blocker that slows the heart rate. It indicates potential cardiovascular complications and should be reported promptly to the healthcare provider for further evaluation and management. Dry mouth, constipation, and increased appetite are common side effects of various medications but are not directly associated with propranolol's mechanism of action.
Question 3 of 5
A nurse is assessing a client who has been taking lithium carbonate. Which of the following findings should the nurse report to the provider?
Correct Answer: B
Rationale: The correct answer is B: Tremors. Tremors are a sign of lithium toxicity and should be reported immediately. Increased urination is a common side effect of lithium but not an urgent concern requiring immediate reporting. Weight gain is also a common side effect of lithium but does not indicate toxicity. Blurred vision is not typically associated with lithium toxicity; therefore, it is not the priority finding to report.
Question 4 of 5
Nurse practitioner prescriptive authority is regulated by:
Correct Answer: C
Rationale: The correct answer is choice C, the State Board of Nursing for each state, because these boards establish the legal scope of practice for nurse practitioners, including prescriptive authority, which varies by state due to differing regulations. Choice A, the National Council of State Boards of Nursing, is incorrect as it provides guidelines and licensure standards but doesn't directly regulate state-specific authority. Choice B, the U.S. Drug Enforcement Administration, is wrong because it oversees controlled substances, not general prescribing rights. Choice D, the State Board of Pharmacy, is also incorrect since it governs pharmacists, not NPs, and has no jurisdiction over their prescriptive authority.
Question 5 of 5
The NP chooses to give cephalexin every 8 hours based on knowledge of the drug's:
Correct Answer: B
Rationale: Choice B is correct because dosing cephalexin every 8 hours aligns with its biological half-life, the time it takes for half the drug to be eliminated, ensuring steady therapeutic levels. Choice A is incorrect as ‘propensity to target receptor' isn't a standard pharmacokinetic term for dosing decisions. Choice C is wrong because pharmacodynamics (drug effects) informs efficacy, not timing. Choice D is incorrect since safety and side effects influence drug choice, not specifically the 8-hour interval.
