, Q1. A researcher identifies a mutation in the gene encoding the regulatory subunit of
protein kinase A (PKA) that prevents cAMP from binding. In a cell type where PKA
phosphorylates a transcription factor that drives expression of a pro-inflammatory
cytokine, what is the most immediate consequence?
A. Constitutive activation of the transcription factor
B. Failure to activate the transcription factor despite elevated cAMP
C. Increased cAMP degradation by phosphodiesterase
D. Uncontrolled cell proliferation
Correct Answer: B. Failure to activate the transcription factor despite elevated cAMP
Rationale: cAMP normally binds the regulatory subunit of PKA, releasing the catalytic
subunit to phosphorylate targets. If the regulatory subunit cannot bind cAMP, PKA
remains inactive, so even high cAMP levels cannot activate the transcription factor.
Constitutive activation would require a different mutation, and increased cAMP
degradation or proliferation are not direct consequences of this specific defect.
Why Wrong:
A - Constitutive activation would require a mutation that keeps PKA active without
cAMP, not one that prevents cAMP binding.
C - cAMP degradation is controlled by phosphodiesterases, not by PKA's regulatory
subunit.
D - Uncontrolled proliferation is not a direct effect of impaired PKA signaling in this
context.

for Disease in Adults and Children, 9th ed., Ch. 2.
Q2. In a patient with chronic heart failure, which compensatory mechanism initially
preserves cardiac output but ultimately contributes to worsening myocardial oxygen
demand and remodeling?
A. Downregulation of beta-adrenergic receptors
B. Activation of the renin-angiotensin-aldosterone system
C. Increased atrial natriuretic peptide secretion
D. Peripheral vasodilation
Correct Answer: B. Activation of the renin-angiotensin-aldosterone system
Rationale: RAAS activation increases preload and afterload via angiotensin II and
aldosterone, initially supporting cardiac output but later increasing wall stress, promoting
fibrosis, and worsening heart failure. Beta-receptor downregulation is a maladaptive
response, not a compensatory mechanism that preserves output. ANP and vasodilation are
counter-regulatory, not primary compensations.
Why Wrong:
A - Beta-receptor downregulation reduces sympathetic responsiveness and is
