Furosemide causes all except –
**Core Concept**
Furosemide is a **loop diuretic** that acts on the ascending limb of the loop of Henle to inhibit the **Na+-K+-2Cl- cotransporter**, leading to increased excretion of sodium, chloride, and water. This results in a decrease in blood volume and subsequently reduces blood pressure.
**Why the Correct Answer is Right**
The correct answer choice is not provided, however, furosemide's mechanism of action typically leads to increased urine production, hypokalemia due to increased potassium excretion, and can cause dehydration if not properly managed.
**Why Each Wrong Option is Incorrect**
**Option A:** Not provided, but typically furosemide would cause an increase in urine output due to its diuretic effect.
**Option B:** Not provided, but furosemide can lead to hypokalemia.
**Option C:** Not provided, but it can cause dehydration.
**Option D:** Not provided, but furosemide increases calcium excretion.
**Clinical Pearl / High-Yield Fact**
A key point to remember is that furosemide can lead to **hypokalemia** due to increased potassium excretion in the urine, necessitating monitoring and possible potassium supplementation.
**Correct Answer:** Not provided in the query.
