Practice Question
The client presents to the emergency department (ED) with a 24-hour history of excessive vomiting. What is most concerning for the ED nurse?
Answer Choices:
Correct Answer:
Metabolic alkalosis
Rationale:
🔶 Prolonged vomiting causes loss of gastric acid (HCl) leading to an alkaline state
🔶 The pH increases while bicarbonate levels rise, producing metabolic alkalosis
🔶 The body compensates by slowing respirations to retain CO₂
🔶 Hypokalemia commonly accompanies this due to hydrogen–potassium ion exchange
🔶 Treatment includes fluid and electrolyte replacement and antiemetic administration
