,300 Exam-Style Questions with Verified Answers
and Rationales
Qn 1. Which statement, if made by a patient, reflects the need for further education
regarding a new prescription of warfarin (Coumadin)?
A A. I should avoid eating large amounts of leafy green vegetables.
B B. I should report any unusual bleeding or bruising to my doctor.
C C. If I get headaches, aspirin is my best option for pain.
D D. I should take my warfarin at the same time every day.
Correct Answer: C. If I get headaches, aspirin is my best option for pain.
Rationale: Aspirin should be avoided in patients taking warfarin because it increases the
risk of bleeding. Patients taking warfarin should be taught to avoid aspirin and other
NSAIDs due to the increased bleeding risk. Acetaminophen is a safer option for pain relief.
[citation:2][citation:5]
Why Wrong:
A. A: This is correct; patients should maintain consistent vitamin K intake from leafy
greens.
B. B: This is correct; patients should monitor for signs of bleeding.
C. D: This is correct; consistent timing is important for maintaining therapeutic INR levels.

Care; Saunders Comprehensive Review; McCuistion's Pharmacology.
Qn 2. Sildenafil (Viagra) is prescribed to treat a patient with erectile dysfunction. A
nurse reviews the patient's medical record and would question the prescription if which
of the following is noted in the history?
A A. Hypertension controlled with lisinopril
B B. Nitroglycerin use for angina
C C. Type 2 diabetes mellitus
D D. Benign prostatic hyperplasia
Correct Answer: B. Nitroglycerin use for angina
, Rationale: Sildenafil is contraindicated with nitrates because the combination can cause
severe hypotension due to synergistic vasodilation. Patients taking nitroglycerin or other
nitrates should not receive sildenafil.[citation:5][citation:8]
Why Wrong:
A. A: Lisinopril is an ACE inhibitor and does not have a significant interaction with
sildenafil.
B. C: Diabetes is not a contraindication to sildenafil, though it may be a risk factor for
erectile dysfunction.
C. D: BPH is not a contraindication to sildenafil.

Care; Saunders Comprehensive Review; McCuistion's Pharmacology.
Qn 3. A patient on simvastatin regularly consumes grapefruit juice. What is the primary
concern?
A A. Decreased statin efficacy
B B. Increased risk of rhabdomyolysis
C C. No significant interaction
D D. Reduced simvastatin metabolism
Correct Answer: B. Increased risk of rhabdomyolysis
Rationale: Grapefruit juice inhibits CYP3A4 in the gut wall, increasing simvastatin
bioavailability. Elevated simvastatin levels increase the risk of rhabdomyolysis and
hepatotoxicity. Patients should avoid grapefruit juice while taking simvastatin.[citation:1]
Why Wrong:
A. A: Grapefruit juice increases statin levels, not decreases efficacy.
B. C: There is a significant and potentially dangerous interaction.
C. D: Grapefruit juice inhibits metabolism, increasing drug levels, but the primary concern
is toxicity.

Care; Saunders Comprehensive Review; McCuistion's Pharmacology.
Qn 4. A patient has been prescribed nitrofurantoin (Furadantin) for a urinary tract
infection. What education would you provide to them?
A A. Take with milk to reduce GI upset.
B B. Wash your mouth out after taking this medicine to avoid staining of the teeth.
C C. Take on an empty stomach for better absorption.
