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 D
Explanation
A. Respiratory Acidosis: Respiratory acidosis results from inadequate ventilation leading to CO₂ retention, which is unrelated to kidney failure.
B. Metabolic Alkalosis: Metabolic alkalosis occurs due to excessive loss of acids (e.g., vomiting) or excess bicarbonate intake. Acute renal failure causes acid retention, not loss.
C. Respiratory Alkalosis: Respiratory alkalosis is caused by hyperventilation and excessive CO₂ loss, not renal dysfunction.
D. Metabolic acidosis: The kidneys play a vital role in acid-base balance by excreting hydrogen ions and reabsorbing bicarbonate. Acute renal failure impairs these functions, leading to acid retention and metabolic acidosis.
Correct Answer is B
Explanation
A. ST depression: ST depression is associated with hypokalemia or ischemia.
B. Tall peaked T waves: Hyperkalemia (K+ > 5.0 mEq/L) causes tall, peaked T waves due to abnormal repolarization. Severe hyperkalemia (>6.5 mEq/L) can lead to cardiac arrest.
C. Prolonged ST segment: Not a characteristic of hyperkalemia.
D. Prominent U wave: A U wave is seen in hypokalemia, not hyperkalemia.
