LPN Pharmacology Multiple Choice Questions Questions
Question 1 of 9
Drugs that are contraindicated in men with benign prostatic hyperplasia include:
Correct Answer: B
Rationale: Choice B is correct because anticholinergics worsen urinary retention in BPH by relaxing bladder muscles, contraindicated per urology guidelines. Choice A is incorrect as testosterone's role is debated, not absolute. Choice C is wrong because alpha blockers treat BPH. Choice D is incorrect since only anticholinergics apply.
Question 2 of 9
Michael has Gilbert syndrome with a genetic variation of UGT1A1. Drugs that could be affected include:
Correct Answer: B
Rationale: Choice B is correct because Gilbert syndrome's UGT1A1 variation impairs irinotecan metabolism, increasing toxicity risk, unlike the others. Choice A is incorrect as warfarin isn't UGT1A1-dependent—it's CYP2C9-related. Choice C is wrong because acetaminophen's glucuronidation isn't significantly UGT1A1-specific in this context. Choice D is incorrect since ibuprofen doesn't rely on UGT1A1.
Question 3 of 9
A patient with chronic back pain that is unrelieved by prescription analgesic medications asks a primary care nurse practitioner (NP) about acupuncture treatments. The NP should tell this patient:
Correct Answer: D
Rationale: The correct answer is D because CAM efficacy, including acupuncture, is often based on observational data rather than definitive trials. Choice A is incorrect (biofield not proven superior). Choice B is wrong (creatine is for muscle, not pain). Choice C is inaccurate (some research exists, though limited).
Question 4 of 9
Examples of Schedule II drugs include:
Correct Answer: A
Rationale: Choice A is correct because oxycodone is a Schedule II drug due to its opioid properties and abuse risk, per DEA. Choice B is incorrect as lorazepam is Schedule IV. Choice C is wrong because marijuana is Schedule I. Choice D is incorrect since only oxycodone fits.
Question 5 of 9
Drugs that are listed as Pregnancy Category X should be:
Correct Answer: A
Rationale: Choice A is correct because Category X drugs have proven fetal risks outweighing benefits, so they're avoided in women of childbearing age unless contraception ensures no pregnancy, per FDA guidelines. Choice B is incorrect as caution alone isn't enough—avoidance is key. Choice C is wrong because use in any trimester is contraindicated. Choice D is incorrect since only A addresses the specific precaution.
Question 6 of 9
A 6-month-old infant has a temperature of 99°F to 100°F and two to three loose stools per day. Other family members have similar symptoms. The infant has had two sets of immunizations at 2 and 4 months of age. The NP should:
Correct Answer: A
Rationale: The correct answer is A because minor illness isn’t a contraindication for vaccines. Choice B is incorrect (delays protection). Choice C is wrong (splitting unnecessary). Choice D is inaccurate (withholding not justified).
Question 7 of 9
Reasons for medication nonadherence include:
Correct Answer: D
Rationale: Choice D is correct because all listed reasons—lack of understanding purpose, cost barriers, and unclear instructions—are common, well-documented causes of nonadherence. Choice A is incorrect alone as it's one factor. Choice B is wrong by itself because cost is just one issue. Choice C is incorrect solo since misunderstanding administration is only part.
Question 8 of 9
Drugs that are prone to cause adverse drug effects include:
Correct Answer: C
Rationale: Choice C is correct because insulins have a narrow therapeutic index, making ADRs like hypoglycemia common if dosing is off, a high-risk profile. Choice A is incorrect as diuretics' ADRs (e.g., electrolyte imbalance) are manageable, less prone. Choice B is wrong because inhaled anticholinergics have fewer systemic effects. Choice D is incorrect since stimulants' ADRs are notable but less frequent than insulin's.
Question 9 of 9
An NP would prescribe the liquid form of ibuprofen for a 6-year-old child because:
Correct Answer: B
Rationale: Choice B is correct because a 6-year-old may struggle to swallow pills, making liquid ibuprofen easier to administer and ensuring compliance. Choice A is incorrect as liquid forms aren't inherently less irritating—irritation depends on the drug. Choice C is wrong because liquids still undergo first-pass metabolism when swallowed. Choice D is incorrect since dosing frequency depends on pharmacokinetics, not form.
