A nurse is caring for a client who is experiencing severe nausea and vomiting after a course of chemotherapy. The nurse should monitor the client for which of the following clinical manifestations?

A. Respiratory acidosis is caused by hypoventilation and CO₂ retention, not by nausea and vomiting. B. Respiratory alkalosis results from hyperventilation, which is unrelated to vomiting. C. Metabolic alkalosis occurs when there is a loss of gastric acid from severe vomiting, leading to an increase in blood pH due to decreased hydrogen ions. This is a common acid-base imbalance in clients with prolonged vomiting. D. Metabolic acidosis is usually caused by diarrhea, renal failure, or diabetic ketoacidosis, not vomiting.
