Quizlet Pharmacology Questions for LPN Questions
Question 1 of 9
A nurse practitioner (NP) is preparing to prescribe a medication for a 5-year-old child. To determine the correct dose for this child, the NP should:
Correct Answer: D
Rationale: The correct answer is D because manufacturer recommendations are the safest and most accurate for pediatric dosing. Choice A is incorrect as one-third is arbitrary. Choice B is wrong since BSA is less reliable than weight-based dosing. Choice C is inaccurate as dividing by weight alone isn’t standard.
Question 2 of 9
Components of a REMS program may include:
Correct Answer: D
Rationale: Choice D is correct because REMS programs can include medication guides (patient education), communication plans (provider awareness), and restricted distribution (controlled access), per FDA guidelines. Choice A is incorrect alone as it's one component. Choice B is wrong by itself because communication is just part. Choice C is incorrect solo since restriction is only one element.
Question 3 of 9
Drugs that are contraindicated in the elderly include:
Correct Answer: B
Rationale: Choice B is correct because diphenhydramine (per Beers Criteria) is contraindicated in the elderly due to anticholinergic effects risking delirium and urinary retention. Choice A is incorrect as acetaminophen is safe. Choice C is wrong because amoxicillin is not contraindicated. Choice D is incorrect since only diphenhydramine applies.
Question 4 of 9
A primary care NP prescribes TMP/SMX for a patient who is experiencing an exacerbation of COPD. The patient calls the NP 2 days later to report increased fever, cough, and shortness of breath. The NP should tell the patient:
Correct Answer: A
Rationale: The correct answer is A because fever, cough, and shortness of breath may signal a serious reaction to TMP/SMX, warranting discontinuation. Choice B is incorrect (these symptoms are also serious). Choice C is wrong (not just disease progression). Choice D is inaccurate (switching not advised).
Question 5 of 9
A patient who has HIV frequently expresses concerns about the costs of treatment. The primary care NP should:
Correct Answer: A
Rationale: The correct answer is A because underdosing risks resistance, worse than no treatment. Choice B is incorrect (half doses dangerous). Choice C is wrong (three agents needed). Choice D is inaccurate (holidays not recommended).
Question 6 of 9
A nurse practitioner (NP) is preparing to prescribe a medication for a 5-year-old child. To determine the correct dose for this child, the NP should:
Correct Answer: D
Rationale: The correct answer is D because manufacturer recommendations are the safest and most accurate for pediatric dosing. Choice A is incorrect as one-third is arbitrary. Choice B is wrong since BSA is less reliable than weight-based dosing. Choice C is inaccurate as dividing by weight alone isn’t standard.
Question 7 of 9
The primary care NP sees a 2-month-old infant for a well-baby examination in late November. The infant was born at 34 weeks' gestation, does not have underlying cardiac or pulmonary conditions, and does not attend daycare. The NP should recommend:
Correct Answer: C
Rationale: The correct answer is C because preterm infants (32-35 weeks) under 3 months at RSV season start need three Synagis doses. Choice A is incorrect (one dose insufficient). Choice B is wrong (prophylaxis indicated). Choice D is inaccurate (three doses, not until April).
Question 8 of 9
Once they have been metabolized by the liver, the metabolites may be:
Correct Answer: D
Rationale: Choice D is correct because liver metabolism can produce metabolites that are more active (e.g., prodrugs like codeine to morphine), less active, or inactive, depending on the drug, making all options possible. Choice A is incorrect as it's only one scenario, not the full range. Choice B is wrong because it excludes cases where metabolites are more active. Choice C is incorrect since not all metabolites are deactivated—some retain or gain activity.
Question 9 of 9
Pharmacokinetic changes in children that affect drug dosing include:
Correct Answer: D
Rationale: Choice D is correct because children have higher gastric pH (affects absorption), slower liver metabolism (prolongs drug action), and more body water (alters distribution), all impacting dosing per pediatric pharmacology. Choice A is incorrect alone as pH is one factor. Choice B is wrong by itself because metabolism is just part. Choice C is incorrect solo since body water is only one aspect.
