What is the common side effect of hyperkalemia in surgical patients?

Bradycardia
Severe headaches
Shortness of breath
Increased blood pressure

The correct answer is: Bradycardia

Hyperkalemia, or elevated potassium levels in the blood, can significantly impact cardiac function, making bradycardia a common side effect in surgical patients. High potassium levels can disrupt the normal electrical conduction in the heart, leading to slower heart rates. This is particularly concerning during and after surgical procedures, where monitoring of electrolytes is crucial due to the potential for shifts in potassium levels. Bradycardia associated with hyperkalemia can manifest as a decrease in heart rate, potentially causing inadequate blood circulation and compromising cardiac output. In surgical patients, this effect can lead to serious complications if not recognized and managed promptly. Thus, monitoring potassium levels and heart rate is essential in the perioperative setting to prevent adverse outcomes related to hyperkalemia.
