ACTUAL EXAM PREP BANK 2026-2027
QUESTIONS WITH VERIFIED ANSWERS &
RATIONALES (PASS GUARANTEED)
This premium study bank features highly specific, multiple-
choice questions mapping directly to the 2026/2027 WGU
D116 Advanced Pharmacology curriculum. Every question
includes a verified correct answer paired with a bold,
italicized clinical rationale to maximize retention and boost
test-day confidence. Perfect for busy MSN and APRN
students, this comprehensive document is optimized for
quick scanning and guaranteed exam success.
Question 1
An Advanced Practice Registered Nurse (APRN) is reviewing the
medication list of a patient diagnosed with chronic open-angle
glaucoma. The patient's history is notable for severe bradycardia
and a second-degree AV block. Which of the following ophthalmic
drops should the APRN avoid prescribing?
A. Latanoprost
B. Timolol
C. Brimonidine
D. Dorzolamide
,Answer: B. Timolol
Rationale: Timolol is a non-selective beta-blocker applied
topically for glaucoma but can undergo significant systemic
absorption. It is strictly contraindicated in patients with
bradycardia, AV blocks, or severe asthma due to the risk of
worsening cardiac conduction and inducing
bronchoconstriction.
Question 2
A patient with a history of severe seasonal allergies requested an
antihistamine that will not interfere with their performance as a
commercial truck driver. Which medication is most appropriate?
A. Diphenhydramine
B. Hydroxyzine
C. Fexofenadine
D. Chlorpheniramine
Answer: C. Fexofenadine
Rationale: Fexofenadine is a second-generation
antihistamine that does not readily cross the blood-brain
barrier. It is considered a true non-drowsy antihistamine,
making it safe for individuals whose occupations require
high levels of alertness, unlike first-generation agents like
diphenhydramine.
Question 3
An APRN is preparing to order an outpatient contrast-enhanced
CT scan for a diabetic patient taking metformin. What clinical
directive must the clinician provide regarding this medication?
A. Double the dose of metformin on the day of the procedure.
B. Discontinue metformin temporarily prior to or at the time of the
,procedure and hold it for 48 hours post-procedure until renal
function is verified.
C. Administer metformin with a high-protein breakfast before the
scan.
D. Switch the patient to an oral sulfonylurea 24 hours prior to
imaging.
Answer: B. Discontinue metformin temporarily prior to or at the
time of the procedure and hold it for 48 hours post-procedure until
renal function is verified.
Rationale: Iodinated contrast media can induce acute renal
impairment, which reduces the excretion of metformin. High
systemic levels of metformin drastically increase the
patient's risk of developing a potentially fatal lactic acidosis.
Question 4
A 64-year-old male with erectile dysfunction is seeking a
prescription for sildenafil. During the history, he mentions taking
sublingual nitroglycerin as needed for stable angina. What is the
correct clinical choice?
A. Prescribe sildenafil at the lowest starting dose.
B. Advise the patient to take sildenafil at least 2 hours after
nitroglycerin.
C. Avoid prescribing sildenafil due to a life-threatening drug-drug
interaction.
D. Switch the patient's nitroglycerin to a long-acting nitrate before
prescribing sildenafil.
Answer: C. Avoid prescribing sildenafil due to a life-threatening
drug-drug interaction.
Rationale: Sildenafil is a PDE-5 inhibitor that potentiates the
vasodilatory actions of organic nitrates like nitroglycerin. Co-
, administration can prompt profound, life-threatening
hypotension and cardiovascular collapse.
Question 5
A patient diagnosed with acute pulmonary edema is admitted to
the emergency department. Which diuretic class and specific
agent is the primary drug of choice to rapidly relieve vascular
congestion?
A. Spironolactone (Potassium-sparing)
B. Hydrochlorothiazide (Thiazide)
C. Furosemide (Loop diuretic)
D. Acetazolamide (Carbonic anhydrase inhibitor)
Answer: C. Furosemide (Loop diuretic)
Rationale: Furosemide is a potent loop diuretic that acts on
the thick ascending limb of the loop of Henle. When
administered intravenously, it provides rapid venodilation
and diuresis, making it the gold standard for acute
pulmonary edema relief.
Question 6
A patient newly diagnosed with postmenopausal osteoporosis is
prescribed oral alendronate. Which administration instruction
must the APRN deliver to ensure safety and prevent esophageal
ulceration?
A. Take the tablet with a full glass of milk right before bedtime.
B. Crush the medication and mix it with food to facilitate
swallowing.
C. Take the medication first thing in the morning with a full glass
of plain water and remain completely upright for at least 30
minutes.
