**Question:** Malignant hyperthermia is associated with all of the following except?

A. Hypothermia
B. Hyperkalemia
C. Acidosis
D. Bradycardia

**Core Concept:** Malignant hyperthermia (MH) is a rare, life-threatening iatrogenic crisis triggered by exposure to certain medications, typically during general anesthesia or muscle relaxant administration. It is characterized by hypermetabolic state, hyperthermia, and often rapid progression to respiratory distress and cardiovascular collapse.

**Why the Correct Answer is Right:** The correct answer, D - Bradycardia, is incorrect because bradycardia refers to a decrease in heart rate, which is not a typical feature of malignant hyperthermia. Instead, MH patients present with tachycardia (rapid heart rate) during the crisis.

**Why Each Wrong Option is Incorrect:**
A. Hypothermia: While MH patients may experience a decrease in body temperature, hypothermia refers to a state of low body temperature, which is not directly associated with MH.
B. Hyperkalemia: Hyperkalemia is defined as elevated potassium levels in the blood, which is not a primary feature of MH. MH patients exhibit hypermetabolic state, hyperthermia, and tachycardia, rather than hyperkalemia.
C. Acidosis: Although MH patients might experience acidemia (acidosis) due to the release of lactic acid, the correct answer (Bradycardia) is more closely related to the hypermetabolic state and tachycardia seen in MH patients.
