Study Guide 2026
This professional clinical resource is a premier test bank explicitly engineered for
graduate nursing students preparing for the high-stakes NU 641 Advanced Clinical
Pharmacology Examination 2. It delivers a high-yield collection of board-style practice
questions, 100% verified correct answers, and comprehensive prescriptive
rationales tailored for advanced practice providers. Reviewing these premium testing
parameters ensures absolute competence across the mechanisms of action,
pharmacokinetics, adverse effect profiles, and black box warnings of major therapeutic
classes—including advanced cardiovascular, renal, respiratory, and central nervous
system medications—to guarantee an A grade on your proctored university
assessment.
1. A patient with acute decompensated heart failure is started on IV furosemide. Which
assessment finding best indicates effective diuresis?
A. Weight loss of 0.5 kg in 24 hours
B. Urine output of 30 mL/hr
C. Decreased jugular venous distention and improved dyspnea
D. Blood pressure increase of 10 mm Hg
Answer: C. Decreased jugular venous distention and improved dyspnea
Rationale: In acute decompensated heart failure, the goal of diuresis is decongestion.
Improvement in JVD, dyspnea, and orthopnea reflects successful volume removal more
directly than a single urine output or weight value.
2. A patient on digoxin has a serum digoxin level of 2.8 ng/mL. Which finding is most
consistent with toxicity?
A. Blood pressure 120/80 mm Hg
B. Visual disturbances with yellow-green halos
C. Heart rate 72 bpm
D. Mild fatigue
Answer: B. Visual disturbances with yellow-green halos
,Rationale: Digoxin toxicity commonly causes visual disturbances (yellow-green halos,
blurred vision), nausea, and arrhythmias. Therapeutic range is 0.5–2.0 ng/mL.
3. Which medication should be avoided in a patient taking sacubitril/valsartan due to a
serious drug interaction?
A. Metformin
B. Enalapril
C. Amlodipine
D. Furosemide
Answer: B. Enalapril
Rationale: Combining sacubitril/valsartan with an ACE inhibitor increases bradykinin
levels and the risk of angioedema. A 36-hour washout is required when switching.
4. A patient with hypertension and gout should avoid which class of antihypertensives?
A. ACE inhibitors
B. Thiazide diuretics
C. Calcium channel blockers
D. ARBs
Answer: B. Thiazide diuretics
Rationale: Thiazide diuretics reduce uric acid excretion and can precipitate gout flares.
They should be avoided in patients with a history of gout.
5. A patient on spironolactone develops a potassium level of 6.0 mEq/L. Which action
should the nurse practitioner take first?
A. Continue the medication
B. Discontinue spironolactone and obtain an ECG
C. Increase the dose
D. Add potassium supplements
,Answer: B. Discontinue spironolactone and obtain an ECG
Rationale: Spironolactone is a potassium-sparing diuretic that can cause hyperkalemia. A
potassium of 6.0 mEq/L is dangerous and requires immediate discontinuation and cardiac
monitoring.
6. Which medication is a selective aldosterone antagonist that reduces mortality in
HFrEF?
A. Furosemide
B. Eplerenone
C. Hydrochlorothiazide
D. Mannitol
Answer: B. Eplerenone
Rationale: Eplerenone is a selective aldosterone antagonist with fewer antiandrogenic
effects than spironolactone and has mortality benefit in HFrEF.
7. A patient on lisinopril develops swelling of the lips and tongue. What is the priority
action?
A. Continue the medication and monitor
B. Discontinue lisinopril immediately and secure the airway
C. Add an antihistamine and continue
D. Switch to an ARB without stopping lisinopril
Answer: B. Discontinue lisinopril immediately and secure the airway
Rationale: Angioedema is a life-threatening adverse effect of ACE inhibitors. The drug
must be stopped immediately, and airway management is the priority.
8. Which medication is a beta blocker with alpha-blocking properties that is used for
hypertension and heart failure?
A. Metoprolol
, B. Carvedilol
C. Atenolol
D. Esmolol
Answer: B. Carvedilol
Rationale: Carvedilol blocks beta-1, beta-2, and alpha-1 receptors, providing vasodilation
in addition to heart rate reduction.
9. A patient with type 2 diabetes on metformin has an HbA1c of 7.8%. Which
medication class should be added for cardiovascular and renal benefit?
A. Sulfonylurea
B. SGLT2 inhibitor
C. Insulin
D. DPP-4 inhibitor
Answer: B. SGLT2 inhibitor
Rationale: SGLT2 inhibitors provide cardiovascular and renal protection in patients with
type 2 diabetes and are recommended when additional therapy is needed.
10. Which medication is a GLP-1 receptor agonist that requires weekly dosing?
A. Exenatide
B. Liraglutide
C. Semaglutide
D. Dulaglutide
Answer: C. Semaglutide
Rationale: Semaglutide is available in weekly injectable and oral formulations. Exenatide is
twice daily or weekly, liraglutide is daily, and dulaglutide is weekly but the question asks
specifically for semaglutide.
