, Q1. A research study examines a novel drug that inhibits the Na+/K+-ATPase pump
in renal tubular cells. Which of the following intracellular changes would most
directly result from this inhibition?
A. Increased intracellular sodium and decreased intracellular potassium
B. Decreased intracellular sodium and increased intracellular potassium
C. Increased intracellular calcium due to enhanced Na+/Ca2+ exchange
D. Decreased intracellular pH due to reduced H+ excretion
Correct Answer: A. Increased intracellular sodium and decreased intracellular
potassium
Rationale: Na+/K+-ATPase pumps 3 Na+ out and 2 K+ in, maintaining low intracellular
Na+ and high intracellular K+. Inhibition leads to accumulation of Na+ and loss of K+.
The secondary effect on Na+/Ca2+ exchange would actually increase intracellular
calcium, but the direct effect is on Na+ and K+ gradients.
Why Wrong:
B - This is the opposite of what occurs; inhibition leads to increased intracellular Na+
and decreased K+.
C - While inhibition can affect Na+/Ca2+ exchange, the direct effect is on Na+ and
K+ gradients, not calcium.
D - Na+/K+-ATPase does not directly transport H+; this is not the most direct
consequence.

Q2. In a patient with chronic heart failure, which compensatory mechanism initially
maintains cardiac output but ultimately contributes to disease progression via
ventricular remodeling?
A. Activation of the renin-angiotensin-aldosterone system (RAAS)
B. Increased atrial natriuretic peptide (ANP) secretion
C. Downregulation of beta-adrenergic receptors
D. Enhanced parasympathetic tone
Correct Answer: A. Activation of the renin-angiotensin-aldosterone system (RAAS)
Rationale: RAAS activation increases preload and afterload via angiotensin II and
aldosterone, initially supporting cardiac output. However, chronic activation leads to
fibrosis, hypertrophy, and remodeling, worsening heart failure. ANP opposes RAAS but is
overwhelmed. Beta-receptor downregulation is a consequence, not a compensatory
mechanism that maintains output. Parasympathetic tone is not increased in heart failure.
Why Wrong:
B - ANP is released in response to atrial stretch and causes vasodilation and
natriuresis, but it is a counter-regulatory mechanism, not the primary compensatory
one that maintains output.
