This practice exam contains 100 multiple-choice questions divided into 6 sections. You have 120 minutes to
complete the entire exam. Each question has four answer choices; select the one best answer. A passing
score of 80% (80/100 correct) is required. Read each scenario carefully before selecting your response.

, Cardiovascular Disorders -- 2026/2027 Edition
Q1 Question 1 of 100
Q1. A 62-year-old male with a 10-year history of hypertension presents with a blood pressure of
162/98 mmHg despite being on lisinopril 20 mg daily. His BMI is 31 and his creatinine is 1.4 mg/dL.
The nurse practitioner adds amlodipine 5 mg daily to his regimen. This combination is appropriate
because ACE inhibitors and calcium channel blockers have which effect when used together?
A. They both reduce heart rate additively
B. They lower blood pressure through complementary mechanisms
C. They both cause significant diuresis
D. They reduce ACE inhibitor-induced cough
Correct Answer: B
Rationale:
ACE inhibitors reduce angiotensin II-mediated vasoconstriction and decrease aldosterone, while calcium
channel blockers cause arterial vasodilation. These complementary mechanisms produce an additive
antihypertensive effect. Neither combination reduces heart rate additively or causes diuresis.
Q2 Question 2 of 100
Q2. A 55-year-old female presents with exertional chest pressure that resolves with rest. Her ECG
shows ST-segment depression of 1 mm in leads V3-V6 during an exercise stress test. The nurse
practitioner interprets these findings as consistent with stable angina and should initiate which
first-line medication class?
A. Calcium channel blockers
B. Beta-blockers
C. Nitrates only
D. Alpha-blockers
Correct Answer: B
Rationale:
Beta-blockers are first-line therapy for stable angina because they reduce myocardial oxygen demand by
decreasing heart rate, contractility, and blood pressure. Calcium channel blockers are second-line or used
when beta-blockers are contraindicated. Nitrates are used for symptom relief but not as first-line monotherapy.

,Q3 Question 3 of 100
Q3. A 71-year-old male with a history of atrial fibrillation on warfarin presents with an INR of 5.2. He
reports no signs of active bleeding. The nurse practitioner should manage this by which approach?
A. Hold warfarin and recheck INR in 24-48 hours
B. Administer vitamin K intravenously
C. Administer fresh frozen plasma immediately
D. Increase the warfarin dose to overcome resistance
Correct Answer: A
Rationale:
An INR above 5 without active bleeding is managed by holding warfarin and monitoring the INR, which
typically normalizes within 24-48 hours. IV vitamin K and fresh frozen plasma are reserved for serious
bleeding. Increasing warfarin would worsen the supratherapeutic state.
Q4 Question 4 of 100
Q4. A 48-year-old African American male with newly diagnosed hypertension has a blood pressure of
148/94 mmHg. He has no comorbidities. Based on current guidelines, the nurse practitioner should
prescribe which class of medication as first-line therapy?
A. Thiazide diuretic or calcium channel blocker
B. ACE inhibitor
C. Beta-blocker
D. Alpha-blocker
Correct Answer: A
Rationale:
In African American patients without comorbidities, thiazide diuretics or calcium channel blockers are
recommended as first-line antihypertensive therapy because they are more effective in this population. ACE
inhibitors are less effective as monotherapy in Black patients and may increase angioedema risk.

, Q5 Question 5 of 100
Q5. A 67-year-old female presents with acute onset of severe tearing chest pain radiating to her back.
Her blood pressure is 180/110 mmHg in the right arm and 142/88 mmHg in the left arm. The nurse
practitioner suspects an aortic dissection and should order which diagnostic study first?
A. Chest X-ray
B. Exercise stress test
C. Transthoracic echocardiography
D. CT angiography of the chest
Correct Answer: D
Rationale:
CT angiography is the preferred initial diagnostic study for suspected aortic dissection because it provides
rapid, high-resolution imaging of the aorta and can identify the dissection flap and extent. A chest X-ray may
show a widened mediastinum but is not definitive. Stress testing is contraindicated in acute dissection.
Q6 Question 6 of 100
Q6. A 58-year-old male with heart failure with reduced ejection fraction (HFrEF) is currently taking
lisinopril, carvedilol, and furosemide. His ejection fraction is 30% and he still has moderate symptoms.
The nurse practitioner should add which medication that has been shown to reduce mortality in
HFrEF?
A. Amlodipine
B. Hydralazine alone
C. Digoxin
D. Spironolactone
Correct Answer: D
Rationale:
Spironolactone, a mineralocorticoid receptor antagonist, has been shown to reduce mortality and
hospitalizations in patients with HFrEF who remain symptomatic despite ACE inhibitor and beta-blocker
therapy. Digoxin reduces hospitalizations but not mortality, and amlodipine does not improve outcomes in
HFrEF.
