, Q1. In a patient with chronic heart failure, which compensatory neurohormonal
mechanism initially maintains cardiac output but ultimately contributes to disease
progression through adverse ventricular remodeling?
A. Activation of the renin-angiotensin-aldosterone system (RAAS)
B. Increased release of atrial natriuretic peptide (ANP)
C. Upregulation of beta-2 adrenergic receptors on cardiomyocytes
D. Enhanced parasympathetic tone to the sinoatrial node
Correct Answer: A. Activation of the renin-angiotensin-aldosterone system (RAAS)
Rationale: Chronic activation of RAAS increases afterload and sodium retention,
promoting fibrosis and remodeling. ANP is compensatory but counteracts RAAS; beta-2
upregulation is not typical (beta-1 downregulation occurs); parasympathetic tone is
reduced in heart failure.
Why Wrong:
B - ANP is a counter-regulatory hormone that opposes RAAS and does not promote
remodeling.
C - Chronic heart failure is characterized by downregulation, not upregulation, of
beta-1 receptors; beta-2 changes are less significant.
D - Parasympathetic tone is typically decreased in heart failure, not enhanced.

Q2. A 45-year-old individual with a history of metabolic syndrome presents with
hypertension and hypokalemia. Laboratory findings show low plasma renin activity
and elevated aldosterone levels. Which of the following mechanisms best explains the
hypertension?
A. Autonomous aldosterone secretion from an adrenal adenoma
B. Renal artery stenosis causing secondary hyperaldosteronism
C. Overactivation of the sympathetic nervous system
D. Cushing syndrome due to ectopic ACTH production
Correct Answer: A. Autonomous aldosterone secretion from an adrenal adenoma
Rationale: Primary aldosteronism (Conn syndrome) is characterized by low renin and
high aldosterone, leading to sodium retention and hypertension. Renal artery stenosis
causes high renin; sympathetic overactivation is not the primary cause; Cushing syndrome
would present with cortisol excess.
Why Wrong:
B - Renal artery stenosis leads to high renin, not low renin.
C - Sympathetic overactivity is not the primary mechanism in primary aldosteronism.
D - Cushing syndrome would have elevated cortisol, not isolated aldosterone excess.
