Section 1: Assessment & Diagnosis
1. A 47-year-old Black woman with a history of an inferior MI and PCI 6 weeks ago
has a current LVEF of 45%. She reports no shortness of breath, orthopnea, or
dyspnea on exertion. Which stage of heart failure best describes her condition?
A) Stage A (At Risk for HF)
B) Stage B (Pre-HF)
C) Stage C (Symptomatic HF)
D) Stage D (Advanced HF)
Answer: B
The correct answer is Stage B (Pre-HF). This patient has structural heart disease (SHD), as
demonstrated by her LVEF of <50%, but she does not yet demonstrate HF symptoms .
Stage A describes patients who are at risk of HF but do not have symptoms, SHD, or
cardiac biomarkers of stretch or injury. Because she had SHD, she does not meet the
definition for Stage A HF. Stage C describes patients with SHD and current or previous
symptoms of HF; Stage D describes patients with marked HF symptoms that interfere with
daily life .
2. A patient presents with dyspnea on exertion, orthopnea, and paroxysmal
nocturnal dyspnea. These symptoms are most characteristic of:
A) Right-sided heart failure
B) Left-sided heart failure
C) High-output heart failure
D) Constrictive pericarditis
,Answer: B
Left-sided heart failure often leads to pulmonary congestion, causing dyspnea on exertion,
orthopnea, and paroxysmal nocturnal dyspnea, as fluid backs up into the lungs . Right-
sided heart failure leads to systemic venous congestion, causing peripheral edema, ascites,
and hepatomegaly .
3. Which biomarker is most useful for diagnosing and prognosticating heart
failure?
A) Troponin I
B) CK-MB
C) B-type natriuretic peptide (BNP)
D) C-reactive protein
Answer: C
BNP and NT-proBNP levels correlate with ventricular wall stress, helping to diagnose and
assess the severity of heart failure . They are the most useful biomarkers for both diagnosis
and prognosis .
4. Which of the following is the most common cause of heart failure in developed
countries?
A) Hypertension
B) Coronary artery disease
C) Valvular heart disease
D) Viral myocarditis
Answer: B
Coronary artery disease (CAD) is the leading cause of heart failure in developed countries
due to ischemic injury to the myocardium, which impairs cardiac function .
5. What is the mechanism of action of ACE inhibitors in heart failure?
A) Increase heart rate
B) Decrease afterload and preload by inhibiting angiotensin II formation
,C) Block beta-adrenergic receptors
D) Promote sodium retention
Answer: B
ACE inhibitors decrease afterload and preload by inhibiting the formation of angiotensin
II, a potent vasoconstrictor. This reduces systemic vascular resistance and lowers cardiac
filling pressures .
6. Which electrolyte abnormality is commonly associated with loop diuretic
therapy in heart failure?
A) Hyperkalemia
B) Hypermagnesemia
C) Hypokalemia
D) Hypercalcemia
Answer: C
Loop diuretics increase renal excretion of potassium, leading to hypokalemia, which can
increase the risk of arrhythmias .
7. Which of the following is a typical finding on a chest X-ray of a patient with
left-sided heart failure?
A) Cardiomegaly and pulmonary congestion
B) Pleural effusion only
C) Cardiomegaly, pulmonary venous congestion, and interstitial edema
D) Normal findings
Answer: C
Left-sided heart failure leads to pulmonary venous congestion and interstitial edema, often
seen as Kerley B lines on a chest X-ray .
8. The NYHA functional classification is primarily based on:
A) Ejection fraction
, B) BNP levels
C) Patient's symptoms and functional limitation
D) Echocardiographic findings
Answer: C
NYHA class I-IV is determined by the degree of symptoms and activity limitation, not
imaging or lab values .
9. Which medication class should be avoided in acute decompensated heart failure
due to negative inotropic effects?
A) ACE inhibitors
B) Beta-blockers
C) Non-dihydropyridine calcium channel blockers (verapamil, diltiazem)
D) ARBs
Answer: C
Non-dihydropyridine calcium channel blockers (e.g., verapamil, diltiazem) have negative
inotropic effects and can worsen systolic function, making them unsuitable for acute
decompensated heart failure .
10. What is the primary underlying pathophysiology of heart failure with
preserved ejection fraction (HFpEF)?
A) Systolic dysfunction
B) Diastolic dysfunction
C) Valvular regurgitation
D) Arrhythmogenic cardiomyopathy
Answer: B
HFpEF is characterized by impaired ventricular relaxation and stiffening, causing diastolic
dysfunction while the EF remains normal or near-normal .
