Patients with a crush injury should be monitored for which condition?

Hypernatremia
Hypercalcemia
Dysrhythmias
Polyuria

The correct answer is: Dysrhythmias

Monitoring patients with a crush injury for dysrhythmias is essential because crush injuries can lead to significant muscle damage and subsequent release of intracellular potassium into the bloodstream. This condition, known as rhabdomyolysis, can result in hyperkalemia, which is an elevated level of potassium in the blood. Hyperkalemia is particularly dangerous because it can disrupt the electrical activity of the heart, leading to life-threatening arrhythmias or dysrhythmias. Additionally, the potential for renal impairment or acute kidney injury secondary to the crush injury and the release of myoglobin into the blood can exacerbate the risk of dysrhythmias. Therefore, close monitoring of heart rhythm and electrolyte levels is crucial in these patients to prevent serious complications.
