## **Core Concept**
Amphotericin B is an antifungal medication used to treat serious fungal infections. It works by binding to fungal cell membranes, creating pores that lead to cell death. However, its use is associated with several side effects, including nephrotoxicity.

## **Why the Correct Answer is Right**
The correct answer, , is associated with Amphotericin B due to its nephrotoxic effects. Amphotericin B can cause renal vasoconstriction, leading to decreased renal blood flow and glomerular filtration rate (GFR). This results in **hypokalemia** (low potassium levels) and **magnesemia** (normal or sometimes low magnesium levels), but more notably, it causes **hyperkalemia** is not typically a concern; instead, **hypokalemia** is a concern. However, the hallmark is the risk of **renal failure** and electrolyte imbalances, particularly **hypokalemia**.

## **Why Each Wrong Option is Incorrect**
- **Option A:**
- **Option B:**
- **Option C:**

## **Clinical Pearl / High-Yield Fact**
A key clinical pearl is that Amphotericin B-induced nephrotoxicity can be mitigated by using **liposomal formulations** of Amphotericin B, which reduce the drug's accumulation in renal tissues. Additionally, monitoring electrolytes, especially potassium, and renal function is crucial during Amphotericin B therapy.

## **Correct Answer:** .
