A nurse is triaging in the emergency room when a client enters complaining of muscle cramps and a feeling of exhaustion after a running competition. Which of the following would the nurse suspect?
Correct answer
B
Rationale
Muscle cramps and exhaustion after intense exercise suggest hyponatremia due to excessive sweating and water intake, diluting sodium levels. Hypernatremia (A) causes neurological symptoms, hyperkalemia (C) causes arrhythmias, and hypokalemia (D) causes weakness but is less likely without diuretic use.
