SECTION 1: HEART FAILURE PATHOPHYSIOLOGY &
NEUROHORMONAL ACTIVATION (Questions 1-40)
1. A 62-year-old male with chronic heart failure is found to have elevated plasma levels of
norepinephrine. This finding is MOST directly related to which compensatory mechanism? Correct
Answer: B) Activation of the sympathetic nervous system
A) Activation of the renin-angiotensin-aldosterone system (RAAS)
B) Activation of the sympathetic nervous system
C) Release of atrial natriuretic peptide (ANP)
D) Endothelial dysfunction
Rationale: In heart failure, decreased cardiac output triggers baroreceptor-mediated activation of the
sympathetic nervous system, leading to increased release of norepinephrine. While this initially supports
cardiac function, chronic sympathetic activation contributes to myocardial toxicity, arrhythmias, and disease
progression. ---
2. A patient with heart failure with reduced ejection fraction (HFrEF) has chronic activation of the
renin-angiotensin-aldosterone system (RAAS). Which of the following is the PRIMARY detrimental
,effect of sustained RAAS activation? Correct Answer: C) Sodium and water retention with
vasoconstriction
A) Increased myocardial contractility
B) Vasodilation and afterload reduction
C) Sodium and water retention with vasoconstriction
D) Increased heart rate
Rationale: Sustained RAAS activation in HFrEF leads to sodium and water retention (via aldosterone),
vasoconstriction (via angiotensin II), and increased cardiac workload. These effects contribute to volume
overload, increased afterload, and progression of ventricular remodeling. ---
3. Which of the following is the primary pathophysiologic mechanism underlying the progressive
ventricular remodeling observed in chronic heart failure with reduced ejection fraction? Correct
Answer: B) Sustained activation of the renin-angiotensin-aldosterone and sympathetic nervous
systems
A) Isolated diastolic dysfunction without neurohormonal activation
B) Sustained activation of the renin-angiotensin-aldosterone and sympathetic nervous systems
C) Primary mitochondrial dysfunction independent of hemodynamic stress
D) Acute coronary plaque rupture leading to irreversible myocyte loss
Rationale: Chronic neurohormonal activation drives myocyte hypertrophy, interstitial fibrosis, and
progressive chamber dilation, which are central to adverse ventricular remodeling in HFrEF. Blocking these
pathways forms the foundation of guideline-directed medical therapy. ---
4. A patient with heart failure with reduced ejection fraction (HFrEF) has chronic activation of the
renin-angiotensin-aldosterone system (RAAS). Which of the following is the PRIMARY detrimental
effect of sustained RAAS activation? Correct Answer: C) Sodium and water retention with
vasoconstriction
A) Increased myocardial contractility
B) Vasodilation and afterload reduction
C) Sodium and water retention with vasoconstriction
D) Increased heart rate
Rationale: Sustained RAAS activation in HFrEF leads to sodium and water retention (via aldosterone),
vasoconstriction (via angiotensin II), and increased cardiac workload. ---
,5. Which statements accurately describe heart failure (HF)? (Select all that apply) E) Hypervolemia
precipitates HF by decreasing cardiac output and increasing oxygen consumption Correct Answer: A
and B
A) A common cause of HF with preserved ejection fraction (HFpEF) is left ventricular dysfunction
B) A primary risk factor for HF is coronary artery disease (CAD)
C) Systolic failure results in a normal left ventricular ejection fraction
D) HF with reduced ejection fraction (HFrEF) is characterized by abnormal resistance to ventricular filling
Rationale: HFpEF (diastolic failure) is characterized by abnormal resistance to ventricular filling.
Hypertension, CAD, advanced age, and diabetes are all risk factors for HF. Ejection fraction (EF) is decreased
in systolic HF (HFrEF), not normal. ---
6. What is the most common cause of heart failure in developed countries? Correct Answer: B)
Coronary artery disease (CAD)
A) Hypertension
B) Coronary artery disease
C) Valvular heart disease
D) Viral myocarditis
Rationale: CAD is the leading cause of heart failure in developed countries due to ischemic injury to the
myocardium, which impairs cardiac function. ---
7. A patient presents with dyspnea on exertion, orthopnea, and paroxysmal nocturnal dyspnea.
Which type of heart failure is most likely? Correct Answer: B) Left-sided heart failure
A) Right-sided heart failure
B) Left-sided heart failure
C) High-output heart failure
D) Constrictive pericarditis
Rationale: 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. ---
8. Which assessment finding may indicate right-sided heart failure? Correct Answer: B) Distended
neck veins
A) Pulmonary edema
B) Distended neck veins
, C) Dry cough
D) Orthopnea
Rationale: Right-sided heart failure may manifest by distended neck veins, dependent edema, hepatomegaly,
weight gain, ascites, anorexia, nausea, nocturia, and weakness. ---
9. A patient with chronic biventricular HF is assessed for paroxysmal nocturnal dyspnea (PND).
Which question is most appropriate? Correct Answer: D) "Do you wake in a panic with a feeling of
suffocation?"
A) "Are you experiencing restlessness and confusion?"
B) "Do you frequently awaken to void during the night?"
C) "Do you have swelling in dependent body areas?"
D) "Do you wake in a panic with a feeling of suffocation?"
Rationale: PND is awakening from sleep with a feeling of suffocation and a need to sit up to be able to
breathe. Patients learn that sleeping with the upper body elevated on several pillows helps prevent PND. ---
10. What signs and symptoms would a patient with left HF present with? (Select all that apply) E)
Shortness of breath Correct Answer: A, B, and E
A) Bilateral crackles
B) Tachycardia
C) Chest pain
D) Wheeze
Rationale: Left-sided heart failure presents with bilateral crackles (pulmonary congestion), tachycardia
(compensatory mechanism), and shortness of breath (dyspnea). Chest pain and wheezing are not primary
signs of left HF. ---
11. The nurse auscultates an S3 heart sound in a patient with heart failure. This finding indicates:
Correct Answer: B) The heart is beginning to fail
A) The heart is compensating well
B) The heart is beginning to fail
C) The patient has valvular disease
D) The patient has pulmonary hypertension
