A patient with acute gastroenteritis has frequent vomiting and diarrhoea. Which laboratory finding is most consistent with loss of gastric acid from prolonged vomiting?
Correct answer: A. Metabolic alkalosis
- A. Metabolic alkalosis
- B. Respiratory alkalosis
- C. Metabolic acidosis
- D. Respiratory acidosis
Explanation
Vomiting removes hydrochloric acid and may produce metabolic alkalosis, especially when fluid and chloride losses are prolonged. Diarrhoea more commonly causes metabolic acidosis through bicarbonate loss.
