LPN Pharmacology Questions Questions
Question 1 of 5
Drugs that should be avoided in men with a history of prostate cancer include:
Correct Answer: A
Rationale:
Choice A is correct because testosterone can fuel prostate cancer growth, so it's avoided in men with that history, per oncology standards.
Choice B is incorrect as estrogen isn't typically contraindicated here.
Choice C is wrong because progesterone lacks a strong link.
Choice D is incorrect since only testosterone is key.
Question 2 of 5
A client is taking levothyroxine for hypothyroidism. Which of the following findings should indicate to the healthcare provider that the client is experiencing levothyroxine toxicity?
Correct Answer: C
Rationale: Heat intolerance is a hallmark sign of levothyroxine toxicity. It indicates that the client may be receiving an excessive dose of levothyroxine, leading to hyperthyroid symptoms. This can happen when the dosage is too high, causing the body to have an excess of thyroid hormone. Weight loss is a common symptom of hyperthyroidism but alone does not specifically indicate levothyroxine toxicity. Insomnia can be related to hyperthyroidism but is not a specific sign of levothyroxine toxicity. Dry skin is more commonly associated with hypothyroidism rather than levothyroxine toxicity.
Question 3 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 4 of 5
Which of the following statements about bioavailability is true?
Correct Answer: A
Rationale:
Choice A is correct because bioavailability—the fraction of drug reaching systemic circulation—is critical for drugs with narrow therapeutic ranges (where small changes risk toxicity or inefficacy) and sustained-release forms (where release rate affects duration).
Choice B is incorrect as bioavailability varies by formulation, not all brands are identical.
Choice C is wrong because dosing frequency doesn't inherently increase bioavailability.
Choice D is incorrect since inert substances can alter absorption, impacting bioavailability.
Question 5 of 5
A healthcare professional is assessing a client who has a new prescription for warfarin. Which of the following findings should the healthcare professional report to the provider?
Correct Answer: D
Rationale: Bleeding gums are a sign of excessive anticoagulation with warfarin, indicating a potential risk of bleeding complications. It is crucial to report this finding promptly to the provider for further assessment and adjustment of the medication regimen to prevent serious bleeding events. Weight gain, frequent urination, and hypokalemia are not typically associated with warfarin use and are not immediate concerns that require urgent reporting to the provider.
