Question 1 of 5
Which of the following actions most likely contributed to the thiazide-induced increase in renal excretion of potassium?
Correct Answer: B
Rationale: The thiazide-induced increase in renal excretion of potassium is most likely due to the blockade of the Na+/K+/2Cl− cotransporter. Thiazide diuretics inhibit the reabsorption of sodium in the distal convoluted tubule which leads to increased sodium and water excretion, as well as potassium excretion. By blocking the Na+/K+/2Cl− cotransporter, thiazides disrupt the normal electrolyte balance in the kidney, resulting in increased potassium excretion.
