What is the action of the thiazide diuretic?
Blocks the sodium pump.
Block the chloride pump.
Blocks the carbonic anhydrase pump.
Blocks the potassium pump.
The Correct Answer is B
Choice A rationale
Thiazide diuretics do not block the sodium pump. They act primarily on the distal convoluted tubule in the kidneys.
Choice B rationale
Thiazide diuretics block the chloride pump in the distal convoluted tubule, preventing the reabsorption of sodium and chloride, leading to increased urine output and decreased blood pressure.
Choice C rationale
Thiazide diuretics do not block the carbonic anhydrase pump. This action is associated with carbonic anhydrase inhibitors.
Choice D rationale
Thiazide diuretics do not block the potassium pump. They can cause potassium loss as a side effect, but this is not their primary mechanism of action.
