Which of the following is not a risk factor for accidental hypothermia?
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 A
Explanation
A. Chloride level would be decreased: Metabolic alkalosis is often associated with hypochloremia, especially when caused by vomiting or diuretics. However, hypokalemia is more clinically significant.
B. Sodium level would be elevated: Sodium levels are not directly affected by metabolic alkalosis.
C. Magnesium level would be elevated: Magnesium levels are not significantly altered in metabolic alkalosis.
D. Potassium level would be decreased: A bicarbonate level of 30 mEq/L indicates metabolic alkalosis. In alkalosis, hydrogen ions shift out of the cells, and potassium moves into the cells, leading to hypokalemia.
Correct Answer is B
Explanation
A. Respiratory Alkalosis: Would have low PaCO2 (<35 mmHg), not high.
B. Partially Compensated Metabolic Alkalosis: The pH is high (alkalosis), and the HCO3 is elevated, which indicates metabolic alkalosis. The PaCO2 is high, meaning the lungs are attempting to compensate by retaining CO₂ to lower the pH. Because the pH is still abnormal, this is partial compensation.
C. Metabolic Acidosis: Would have low pH and low HCO3 (<22 mEq/L).
D. Fully Compensated Respiratory Acidosis: The primary problem is metabolic, not respiratory.
