Hypokalemia is seen in therapy with
**Core Concept**
Hypokalemia refers to a state of abnormally low potassium levels in the blood, often resulting from excessive potassium loss or inadequate potassium intake. This condition can be caused by various factors, including medications that promote potassium excretion.
**Why the Correct Answer is Right**
The correct answer involves a medication that acts by increasing the secretion of potassium ions into the urine, thereby leading to hypokalemia. This process is mediated by the sodium-potassium pump in the renal tubules, which is inhibited by certain medications. The inhibition of the sodium-potassium pump leads to a decrease in the reabsorption of potassium ions, resulting in increased potassium excretion.
**Why Each Wrong Option is Incorrect**
* **Option A:** This medication is not typically associated with hypokalemia as a side effect.
* **Option B:** This medication works by inhibiting the reabsorption of sodium ions, which actually increases potassium reabsorption.
* **Option C:** This medication does not have a significant effect on potassium levels.
**Clinical Pearl / High-Yield Fact**
The most common medications associated with hypokalemia are diuretics, particularly loop diuretics and thiazide diuretics. These medications increase potassium excretion by inhibiting the sodium-potassium pump in the renal tubules.
**Correct Answer:** D. Digitalis.
