Pharmacology NCLEX PN Questions Questions
Question 1 of 9
Food or drink that should be avoided when taking a prescription for doxycycline includes:
Correct Answer: A
Rationale: Choice A is correct because milk's calcium chelates doxycycline, decreasing absorption and antibiotic effectiveness, a well-known interaction to avoid. Choice B is incorrect as orange juice doesn't significantly impair doxycycline. Choice C is wrong because grapefruit juice's CYP3A4 effect isn't relevant here. Choice D is incorrect since tomato juice doesn't interact notably.
Question 2 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 3 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 4 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.
Question 5 of 9
Transgender men who are receiving testosterone therapy should have monitoring of:
Correct Answer: D
Rationale: Choice D is correct because testosterone therapy in transgender men can raise lipids (CVD risk), increase hemoglobin/hematocrit (polycythemia), and affect liver function, requiring monitoring per guidelines. Choice A is incorrect alone as lipids are one aspect. Choice B is wrong by itself because hematocrit is just part. Choice C is incorrect solo since liver is only one factor.
Question 6 of 9
Strategies to prevent dependence include:
Correct Answer: D
Rationale: Choice D is correct because short-term use (limits exposure), education (informs patients), and monitoring (early detection) all prevent dependence, per clinical guidelines. Choice A is incorrect alone as it's one strategy. Choice B is wrong by itself because education is just part. Choice C is incorrect solo since monitoring is only one approach.
Question 7 of 9
Two different pain medications are given together for pain relief. The drug-drug interaction is:
Correct Answer: D
Rationale: Choice D is correct because giving two pain medications together typically results in an additive effect, where their combined relief equals the sum of their individual effects, a common strategy in pain management. Choice A is incorrect as synergy implies a greater-than-sum effect, not specified here. Choice B is wrong because antagonism reduces effects, opposite to the goal. Choice C is incorrect since potentiation enhances one drug's effect by another, not necessarily equal summing.
Question 8 of 9
The parent of a 2-month-old infant who will soon begin daycare refuses the rotavirus vaccine (RV) because of fears of intussusception. The parent tells the primary care NP that the daycare is strict about preventing infants who have fever or gastrointestinal symptoms from attending. The NP should tell the parent that:
Correct Answer: B
Rationale: The correct answer is B because asymptomatic rotavirus spread is possible, bypassing daycare rules. Choice A is incorrect (herd immunity unreliable here). Choice C is wrong (intussusception risk reduced, not absent). Choice D is inaccurate (antibiotics ineffective).
Question 9 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.
