Cardiac arrest
Falling through the ice
Head trauma
Drug use
The Correct Answer is A
A. Cardiac arrest: Cardiac arrest is a complication of severe hypothermia, not a risk factor.
B. Falling through the ice: Major risk factor for accidental hypothermia due to immersion in cold water.
C. Head trauma: Impaired thermoregulation in the brainstem can cause hypothermia.
D. Drug use: Certain drugs (e.g., alcohol, sedatives) impair the body’s ability to regulate temperature, increasing hypothermia risk.

Correct Answer is C
Explanation
A. Administer supplemental oxygen: Hypokalemia primarily affects cardiac and neuromuscular function, not oxygenation. Oxygen may be needed if dysrhythmias develop but is not the highest priority.
B. Seizure precautions: While severe hypokalemia can cause muscle weakness, seizures are not the primary concern. Cardiac effects take priority.
C. Cardiac monitoring: A potassium level of 2.2 mEq/L is critically low, increasing the risk of life-threatening cardiac arrhythmias. Continuous cardiac monitoring helps detect dangerous dysrhythmias like ventricular tachycardia.
D. Initiating a fluid restriction: Fluid restriction is more relevant for hyperkalemia or fluid overload, not hypokalemia.
