Pharmacology NCLEX PN Questions Questions
Question 1 of 9
Women who are pregnant should avoid taking:
Correct Answer: B
Rationale: Choice B is correct because Category X drugs (e.g., isotretinoin) have proven fetal harm outweighing benefits, so pregnant women must avoid them, per FDA classification. Choice A is incorrect as Category C drugs (e.g., fluoxetine) are used if benefits outweigh risks. Choice C is wrong because Category B drugs (e.g., acetaminophen) are generally safe. Choice D is incorrect since only Category X is universally avoided.
Question 2 of 9
A 13-month-old child drinks 40 to 48 ounces of milk every day. The parents report that the toddler eats a variety of baby fruits and vegetables but refuses meats and cereals. The primary care NP should order a:
Correct Answer: A
Rationale: The correct answer is A because a milk-heavy, low-iron diet risks anemia, checked via CBC. Choice B is incorrect (ferritin secondary). Choice C is wrong (vitamin D not primary). Choice D is inaccurate (calcium not the issue).
Question 3 of 9
A 75-year-old patient who lives alone will begin taking a narcotic analgesic for pain. To help ensure patient safety, the NP prescribing this medication should:
Correct Answer: D
Rationale: The correct answer is D because narcotics affect the CNS, increasing fall risk in the elderly, necessitating cognitive and motor evaluation. Choice A is incorrect as sleep patterns are less critical for safety. Choice B is wrong since constipation isn’t the primary safety concern. Choice C is inaccurate as renal function isn’t the main focus here.
Question 4 of 9
A patient is diagnosed with lupus and reports occasional use of herbal supplements. The primary care NP should caution this patient to avoid:
Correct Answer: B
Rationale: The correct answer is B because echinacea can worsen lupus symptoms, even with immunosuppressants. Choices A, C, and D are incorrect as they don’t specifically exacerbate lupus.
Question 5 of 9
A 75-year-old patient who lives alone will begin taking a narcotic analgesic for pain. To help ensure patient safety, the NP prescribing this medication should:
Correct Answer: D
Rationale: The correct answer is D because narcotics affect the CNS, increasing fall risk in the elderly, necessitating cognitive and motor evaluation. Choice A is incorrect as sleep patterns are less critical for safety. Choice B is wrong since constipation isn’t the primary safety concern. Choice C is inaccurate as renal function isn’t the main focus here.
Question 6 of 9
Drugs that are commonly counterfeited include:
Correct Answer: D
Rationale: Choice D is correct because sildenafil (Viagra), oxycodone (opioid), and atorvastatin (statin) are high-demand drugs often counterfeited due to cost and abuse potential, per FDA reports. Choice A is incorrect alone as it's one drug. Choice B is wrong by itself because oxycodone is just part. Choice C is incorrect solo since atorvastatin is only one example.
Question 7 of 9
Treatment goals in prescribing should:
Correct Answer: B
Rationale: Choice B is correct because treatment goals should prioritize the patient's needs, preferences, and outcomes, aligning with patient-centered care principles. Choice A is incorrect as not all conditions are curable—some require management. Choice C is wrong because provider convenience isn't the goal; patient benefit is. Choice D is incorrect since cost is a factor, not the primary focus.
Question 8 of 9
Infant factors that affect intake of drugs via breast milk include:
Correct Answer: D
Rationale: Choice D is correct because infant age (newborns metabolize slower), milk volume (more intake, more drug), and weight (affects dose per kg) all influence drug intake from milk, per pediatric pharmacology. Choice A is incorrect alone as age is one factor. Choice B is wrong by itself because volume is just part. Choice C is incorrect solo since weight is only one element.
Question 9 of 9
Alterations in drug metabolism among Asians may lead to:
Correct Answer: A
Rationale: Choice A is correct because genetic polymorphisms, like reduced CYP2D6 activity in some Asians, slow antidepressant metabolism, necessitating lower doses to avoid toxicity. Choice B is incorrect as neuroleptic metabolism isn't universally faster—data varies by drug and enzyme. Choice C is wrong because alcohol metabolism (via ADH/ALDH) may be faster in some Asians, not increased requiring higher doses. Choice D is incorrect since slower alcohol metabolism is less common and not the primary focus here.
