Quizlet Pharmacology Questions for LPN Questions
Question 1 of 9
Patients may prefer brand-name drugs over generics due to:
Correct Answer: A
Rationale: Choice A is correct because some patients perceive brand-name drugs as higher quality due to marketing or familiarity, despite bioequivalence. Choice B is incorrect as generics are cheaper, not brand-name. Choice C is wrong because side effects are equivalent. Choice D is incorrect since only A applies.
Question 2 of 9
A primary care nurse practitioner (NP) prescribes a drug to an 80-year-old African-American woman. When selecting a drug and determining the correct dose, the NP should understand that the knowledge of how age, race, and gender may affect drug excretion is based on an understanding of:
Correct Answer: B
Rationale: The correct answer is B because pharmacokinetics studies how the body processes drugs, including excretion affected by age, race, and gender. Choice A is incorrect as bioavailability focuses on drug availability, not excretion. Choice C is wrong since pharmacodynamics studies drug effects, not excretion. Choice D is inaccurate as it’s too broad and not specific to drug processing.
Question 3 of 9
Medication errors can occur due to:
Correct Answer: D
Rationale: Choice D is correct because poor handwriting, sound-alike names (e.g., Celebrex vs. Celexa), and look-alike packaging all contribute to medication errors, per safety studies. Choice A is incorrect alone as it's one cause. Choice B is wrong by itself because sound-alikes are just one risk. Choice C is incorrect solo since packaging is only part of the problem.
Question 4 of 9
Which of the following has influenced an emphasis on primary care education in medical schools?
Correct Answer: A
Rationale: The correct answer is A because the Physician Payment Review Commission in 1992 increased financial reimbursement for primary care providers, incentivizing medical schools to focus on training more primary care physicians to address shortages. Choice B is incorrect as competition from nonphysicians rose coincidentally, not as a primary driver. Choice C is wrong because monopolistic control isn’t a goal of medical education. Choice D is inaccurate since nonphysicians have shown increasing success in primary care, not variable success, but this wasn’t the main influence.
Question 5 of 9
Drugs that may cause increased risk of osteoporosis include:
Correct Answer: C
Rationale: Choice C is correct because corticosteroids (e.g., prednisone) increase bone resorption, raising osteoporosis risk, unlike the others. Choice A is incorrect as testosterone supports bone density. Choice B is wrong because estrogen prevents osteoporosis. Choice D is incorrect since only corticosteroids fit.
Question 6 of 9
Drugs that are safe for breastfeeding include:
Correct Answer: B
Rationale: Choice B is correct because acetaminophen is safe for breastfeeding, with low milk levels and no significant infant effects, per AAP guidelines. Choice A is incorrect as fluoxetine's milk transfer risks infant exposure. Choice C is wrong because isotretinoin isn't safe—it's contraindicated in breastfeeding due to toxicity. Choice D is incorrect since only acetaminophen is safe.
Question 7 of 9
Over-the-counter drugs that should be avoided in patients with liver disease include:
Correct Answer: A
Rationale: Choice A is correct because acetaminophen is hepatotoxic in high doses, especially risky in liver disease, per hepatology guidelines. Choice B is incorrect as aspirin's liver impact is minimal. Choice C is wrong because ibuprofen is metabolized renally, less liver-dependent. Choice D is incorrect since only acetaminophen fits.
Question 8 of 9
A primary care nurse practitioner (NP) prescribes a drug to an 80-year-old African-American woman. When selecting a drug and determining the correct dose, the NP should understand that the knowledge of how age, race, and gender may affect drug excretion is based on an understanding of:
Correct Answer: B
Rationale: The correct answer is B because pharmacokinetics studies how the body processes drugs, including excretion affected by age, race, and gender. Choice A is incorrect as bioavailability focuses on drug availability, not excretion. Choice C is wrong since pharmacodynamics studies drug effects, not excretion. Choice D is inaccurate as it’s too broad and not specific to drug processing.
Question 9 of 9
Drugs that may cause renal impairment in the elderly include:
Correct Answer: D
Rationale: Choice D is correct because acetaminophen (high doses), NSAIDs (e.g., ibuprofen), and aminoglycosides (e.g., gentamicin) can impair renal function, worsened by age-related decline, per nephrology data. Choice A is incorrect alone as it's one risk. Choice B is wrong by itself because NSAIDs are just part. Choice C is incorrect solo since aminoglycosides are only one class.
