Question 1 of 5
Which of the following actions best explains the potassium-sparing effect of this drug?
Correct Answer: B
Rationale: The correct answer is B: Blockade of Na+ channels in the collecting duct. This action prevents Na+ reabsorption, leading to increased Na+ in the urine and decreased K+ secretion. This mechanism is seen in potassium-sparing diuretics like amiloride and triamterene. Choices A and C do not directly impact potassium sparing. Choice D is incorrect as aldosterone receptor blockade would lead to increased K+ excretion.
