Domain Percentage
Assessment 32%
Diagnosis 27%
Plan 27%
Evaluation 15%
The actual FNP exam consists of 150 questions (135 scored) with a 3-hour time limit .
SECTION 1: CARDIOLOGY & VASCULAR DISORDERS
(Questions 1-25)
Question 1
A 45-year-old male with a history of hypertension presents with a blood pressure of
,148/92 mmHg on two separate occasions. He has no other comorbidities. According to
current guidelines, what is the most appropriate initial management?
A) Begin antihypertensive medication immediately
B) Recommend lifestyle modification and recheck in 3-6 months
C) Refer to cardiology for further evaluation
D) Order an echocardiogram to assess for target organ damage
Answer: B) Recommend lifestyle modification and recheck in 3-6 months
Rationale: For patients with Stage 1 hypertension who have no other comorbidities or
evidence of target organ damage, lifestyle modification is recommended for 3-6 months
before initiating pharmacotherapy. If blood pressure remains elevated after this period,
medication would be indicated .
Question 2
A patient with a history of heart failure presents with shortness of breath, orthopnea,
and an S3 gallop on auscultation. What is the most likely diagnosis?
A) Aortic stenosis
B) Mitral regurgitation
C) Heart failure exacerbation
D) Atrial fibrillation
Answer: C) Heart failure exacerbation
Rationale: An S3 gallop is a low-pitched, early diastolic sound that occurs in patients
with heart failure due to rapid ventricular filling in a dilated ventricle. It is associated with
volume overload and reduced ejection fraction. Orthopnea and dyspnea are classic
heart failure symptoms.
,Question 3
Which ECG change is most characteristic of hyperkalemia?
A) Peaked T waves
B) ST elevation
C) U waves
D) Prolonged QT interval
Answer: A) Peaked T waves
Rationale: Hyperkalemia produces tall, peaked ("tented") T waves on ECG, particularly in
the precordial leads. As hyperkalemia worsens, ECG changes progress to prolonged PR
interval, widened QRS, and ultimately sine wave pattern. U waves are seen in
hypokalemia.
Question 4
A 65-year-old male presents with syncope, dyspnea on exertion, and chest pain. On
physical exam, you note a systolic ejection murmur that increases with squatting. What
is the most likely diagnosis?
A) Aortic stenosis
B) Hypertrophic cardiomyopathy
C) Mitral valve prolapse
D) Pulmonary stenosis
Answer: A) Aortic stenosis
Rationale: Aortic stenosis presents with the classic triad of syncope, dyspnea, and chest
pain (angina). The murmur is a systolic ejection murmur heard best at the right upper
, sternal border, radiating to the carotids. It increases with squatting (increases preload)
and decreases with Valsalva .
Question 5
A patient with atrial fibrillation is at increased risk for which of the following?
A) Stroke
B) Heart failure
C) Embolic events
D) All of the above
Answer: D) All of the above
Rationale: Atrial fibrillation increases the risk of stroke (due to thromboembolism from
the left atrium), heart failure (due to loss of atrial kick and rapid ventricular response),
and systemic embolic events. Anticoagulation is indicated based on CHA₂DS₂-VASc
score.
Question 6
A patient is prescribed a beta-blocker for hypertension. What is the mechanism of
action for beta-blockers?
A) Blockade of alpha-adrenergic receptors
B) Blockade of beta-adrenergic receptors
C) Inhibition of angiotensin-converting enzyme
D) Blockade of calcium channels
Answer: B) Blockade of beta-adrenergic receptors
