Question 1. A patient scenario highlights Na+-K+ ATPase. Which statement best
explains the expected physiologic response?
A. Na+-K+ ATPase is driven mainly by passive structural changes and is largely
independent of receptor or transporter activity.
B. The primary mechanism in Na+-K+ ATPase is a regulated physiologic process
that preserves homeostasis under changing conditions.
C. Na+-K+ ATPase typically causes the opposite directional change from what is
observed clinically in normal compensation.
D. Na+-K+ ATPase has minimal influence on organ-level function and rarely
contributes to measurable clinical findings.
✅ Correct Answer: B
Rationale: The primary mechanism in Na+-K+ ATPase is a regulated physiologic
process that preserves homeostasis under changing conditions. This aligns with
core cellular physiology principles and predicts exam-style findings. Option A
overstates passive effects, option C reverses the expected direction of response,
and option D underestimates clinical relevance.
