Questions with Correct Answers and Detailed
Rationales
Question 1
A 65-year-old male with a history of hypertension and type 2 diabetes presents
with complaints of chest tightness and shortness of breath when walking up stairs.
The symptoms are relieved with rest. Which of the following is the most likely
diagnosis?
A) Unstable angina
B) Stable angina
C) Myocardial infarction
D) Pericarditis
Answer: B
Rationale: Stable angina is characterized by chest discomfort that occurs
predictably with exertion or emotional stress and is relieved by rest or
nitroglycerin. The symptoms are typically reproducible with a consistent level of
activity. Unstable angina occurs at rest or with minimal exertion and represents an
acute coronary syndrome requiring immediate intervention. Myocardial infarction
presents with more severe symptoms that are not relieved by rest. Pericarditis pain
is typically sharp, pleuritic, and positional.
Question 2
A 72-year-old patient with heart failure with reduced ejection fraction (HFrEF) is
prescribed sacubitril/valsartan (Entresto). The nurse practitioner understands that
this medication works by:
pg. 1
,2
A) Blocking angiotensin II receptors and inhibiting neprilysin
B) Blocking beta-adrenergic receptors
C) Inhibiting calcium channel receptors
D) Increasing cardiac contractility through phosphodiesterase inhibition
Answer: A
Rationale: Sacubitril/valsartan is an angiotensin receptor-neprilysin inhibitor
(ARNI). Valsartan blocks angiotensin II receptors, while sacubitril inhibits
neprilysin, an enzyme that breaks down natriuretic peptides. This leads to
vasodilation, natriuresis, and reduced cardiac remodeling. The medication has been
shown to reduce mortality and hospitalizations in HFrEF patients. Beta-blockers,
calcium channel blockers, and phosphodiesterase inhibitors work through different
mechanisms.
Question 3
A 68-year-old patient with a history of atrial fibrillation is taking warfarin. The
nurse practitioner should monitor which laboratory value to assess the therapeutic
effectiveness of this medication?
A) Activated partial thromboplastin time (aPTT)
B) International normalized ratio (INR)
C) Platelet count
D) Prothrombin time (PT) alone
Answer: B
Rationale: Warfarin therapy is monitored using the International Normalized
Ratio (INR), which standardizes prothrombin time (PT) across different
laboratories. The therapeutic INR for atrial fibrillation is typically 2.0-3.0. aPTT is
used to monitor heparin therapy. Platelet count is monitored for heparin-induced
thrombocytopenia. PT alone is less reliable due to variability in reagents between
laboratories.

Question 4
A patient with acute coronary syndrome is prescribed clopidogrel (Plavix) in
addition to aspirin. The nurse practitioner understands that the purpose of dual
antiplatelet therapy is to:
A) Reduce the risk of bleeding
B) Prevent stent thrombosis and reduce cardiovascular events
C) Dissolve existing coronary artery thrombi
D) Reduce the need for coronary artery bypass surgery
Answer: B
Rationale: Dual antiplatelet therapy (aspirin plus a P2Y12 inhibitor such as
clopidogrel) is used to prevent stent thrombosis and reduce the risk of recurrent
cardiovascular events in patients with acute coronary syndrome and those
undergoing percutaneous coronary intervention with stent placement. This therapy
does not reduce bleeding risk; in fact, it increases it. Thrombolytics dissolve
thrombi. The therapy does not directly reduce the need for bypass surgery.
Question 5
A 55-year-old patient with hypertension is prescribed amlodipine. The nurse
practitioner should educate the patient about which common side effect of this
medication?
A) Cough
B) Peripheral edema
C) Bradycardia
D) Hyperkalemia
Answer: B
Rationale: Amlodipine is a dihydropyridine calcium channel blocker that causes
peripheral vasodilation. The most common side effect is peripheral edema due to
increased capillary hydrostatic pressure. Cough is more common with ACE
inhibitors. Bradycardia is more common with non-dihydropyridine calcium

, 4
channel blockers (e.g., verapamil, diltiazem) and beta-blockers. Hyperkalemia is
more common with ACE inhibitors and potassium-sparing diuretics.
Question 6
A patient with heart failure is prescribed furosemide (Lasix). The nurse practitioner
should monitor for which electrolyte imbalance?
A) Hyperkalemia
B) Hypokalemia
C) Hypernatremia
D) Hypercalcemia
Answer: B
Rationale: Furosemide is a loop diuretic that inhibits sodium and chloride
reabsorption in the ascending loop of Henle. This leads to increased excretion of
potassium, magnesium, and calcium, resulting in hypokalemia, hypomagnesemia,
and hypocalcemia. Hypokalemia can precipitate cardiac arrhythmias, especially in
patients taking digoxin. Potassium-sparing diuretics cause hyperkalemia.
Question 7
A 60-year-old patient with a history of smoking and hyperlipidemia presents with
intermittent claudication. The nurse practitioner recognizes this as a symptom of:
A) Venous insufficiency
B) Peripheral arterial disease
C) Deep vein thrombosis
D) Lymphedema
Answer: B
Rationale: Intermittent claudication is the classic symptom of peripheral arterial
disease (PAD). It is characterized by muscle pain (typically in the calf, thigh, or
buttock) that occurs with exercise and is relieved by rest. This occurs due to
