NSG 6001 EXAM 200 ACTUAL QUESTIONS AND CORRECT
ANSWERS WITH RATIONALE LATEST 2026 ALREADY
GRADED A+
This comprehensive 200-question bank for NSG 6001 (Advanced
Pharmacology) is designed to cover the core competencies expected of
advanced practice nursing students. The questions are meticulously crafted to
be 100% unique, with no repetition of clinical scenarios, drug mechanisms,
adverse effects, or drug-drug interactions. Each question includes four
plausible multiple-choice options, a clearly identified correct answer, and a
detailed rationale that explains the pharmacological principle, mechanism of
action, clinical application, or monitoring parameter. The content spans
major drug classes, including antihypertensives, anticoagulants, antibiotics,
antidepressants, anticonvulsants, antipsychotics, and medications for diabetes,
heart failure, pain, and endocrine disorders. Special attention is given to high-
yield topics such as renal/hepatic dose adjustments, QT prolongation, black
box warnings, pregnancy categories, CYP450 interactions, and management
of toxicity. This resource is ideal for exam preparation, clinical reasoning
practice, and reinforcement of evidence-based prescribing principles for the
FNP, AGNP, or other advanced practice roles.
1. A patient with heart failure and reduced ejection fraction is started on
sacubitril/valsartan. Which adverse effect requires the most immediate monitoring?
A) Hyperkalemia
B) Angioedema
C) Hypotension
D) Cough
Correct Answer: C
Rationale: Sacubitril/valsartan causes significant vasodilation, and hypotension is
the most common dose-limiting adverse effect, especially within the first 3 weeks
of therapy. Hyperkalemia and angioedema are possible but less immediate. Cough
is more associated with ACE inhibitors alone.
2. A 72-year-old patient with chronic kidney disease stage 3 is prescribed
gabapentin for neuropathic pain. What dose adjustment is required?
A) No adjustment needed
B) Reduce dose by 25%
C) Reduce dose by 50%
,D) Increase dose due to decreased protein binding
Correct Answer: C
Rationale: Gabapentin is renally excreted unchanged. In CKD stage 3 (GFR 30–
59), a 50% dose reduction is recommended to avoid toxicity such as sedation and
confusion.
3. Which antibiotic is contraindicated in a patient with a history of prolonged QT
interval?
A) Azithromycin
B) Doxycycline
C) Metronidazole
D) Amoxicillin
Correct Answer: A
Rationale: Azithromycin prolongs the QT interval and can precipitate torsades de
pointes. Doxycycline, metronidazole, and amoxicillin have minimal QT effects.
4. A patient on lithium therapy develops coarse tremors, nausea, and diarrhea.
Serum lithium level is 2.1 mEq/L. What is the next step?
A) Increase fluid intake
B) Hold lithium and check renal function
C) Add a beta-blocker for tremors
D) Reduce dose by 25%
Correct Answer: B
Rationale: Lithium levels above 2.0 mEq/L indicate toxicity. The drug should be
held immediately, and renal function should be assessed. Fluid intake alone is
insufficient, and adding medications does not address toxicity.
5. Which statin has the greatest potential for drug-drug interactions via CYP3A4
inhibition?
A) Pravastatin
B) Rosuvastatin
C) Atorvastatin
D) Fluvastatin
Correct Answer: C
Rationale: Atorvastatin is metabolized by CYP3A4 and has significant interactions
with azole antifungals, macrolides, and grapefruit juice. Pravastatin and
rosuvastatin are minimally metabolized by CYP; fluvastatin uses CYP2C9.
6. A 55-year-old female with osteoporosis is prescribed alendronate. What
instruction is most important?
,A) Take with orange juice
B) Take with a full glass of water and remain upright for 30 minutes
C) Take at bedtime to reduce side effects
D) Crush the tablet for easier absorption
Correct Answer: B
Rationale: Alendronate must be taken with plain water and the patient must stay
upright for at least 30 minutes to prevent esophageal irritation and ulceration.
Orange juice reduces absorption, and crushing alters the formulation.
7. A patient on metformin is scheduled for an IV contrast study. What should be
done prior to the procedure?
A) Continue metformin as usual
B) Hold metformin 48 hours before and after
C) Hold metformin on the day of procedure and restart 48 hours after
D) Double the dose to prevent hyperglycemia
Correct Answer: C
Rationale: Metformin should be held on the day of IV contrast and restarted 48
hours after if renal function is stable to prevent lactic acidosis. Holding 48 hours
before is excessive.
8. Which class of antidepressants is most dangerous in overdose?
A) SSRIs
B) SNRIs
C) Tricyclic antidepressants
D) MAO inhibitors
Correct Answer: C
Rationale: Tricyclic antidepressants cause fatal arrhythmias, seizures, and coma in
overdose due to sodium channel blockade. SSRIs and SNRIs are safer; MAOIs
have fewer cardiac effects in overdose.
9. A patient with gout is started on allopurinol. Which lab value should be
monitored closely?
A) Serum potassium
B) Serum creatinine
C) Hemoglobin A1c
D) Liver transaminases
Correct Answer: B
Rationale: Allopurinol is renally excreted and can cause nephrotoxicity. Serum
creatinine should be monitored, especially in patients with pre-existing renal
disease. Liver enzymes are less commonly affected.
, 10. Which medication is preferred for acute migraine with aura?
A) Naproxen
B) Sumatriptan
C) Propranolol
D) Amitriptyline
Correct Answer: B
Rationale: Sumatriptan is a triptan that constricts cranial vessels and is first-line for
acute migraine with or without aura. Naproxen is less effective. Propranolol and
amitriptyline are prophylactic, not acute.
11. A patient with type 2 diabetes and heart failure is started on empagliflozin.
What is the primary benefit of this medication beyond glycemic control?
A) Weight loss
B) Reduction in cardiovascular mortality
C) Increase in HDL cholesterol
D) Decrease in blood pressure
Correct Answer: B
Rationale: Empagliflozin, an SGLT2 inhibitor, has shown a significant reduction in
cardiovascular mortality and hospitalizations for heart failure in clinical trials,
independent of its glucose-lowering effects. While weight loss and blood pressure
reduction occur, they are not the primary cardiovascular benefit.
12. Which opioid is preferred for patients with renal impairment due to fewer
active metabolites?
A) Morphine
B) Codeine
C) Fentanyl
D) Hydrocodone
Correct Answer: C
Rationale: Fentanyl is metabolized in the liver to inactive metabolites and is safer
in renal impairment. Morphine and codeine accumulate active metabolites that can
cause toxicity; hydrocodone also relies on renal excretion.
13. A patient on digoxin presents with nausea, vomiting, and yellow vision. What
electrolyte imbalance most likely precipitated this toxicity?
A) Hyperkalemia
B) Hypokalemia
C) Hypercalcemia
D) Hypermagnesemia
