Answer Choices:
Metabolic alkalosis
🤮Vomiting causes loss of gastric hydrogen ions, reducing acid and elevating serum bicarbonate levels.
🫁The body compensates through hypoventilation, slowing respirations to retain CO₂ and lower pH toward normal.
⚖️Elevated bicarbonate with respiratory compensation is diagnostic of metabolic alkalosis, not acidosis or primary respiratory disorders.
💡 Neuromuscular irritability—numbness and tingling around the mouth and in extremities—occurs as ionized calcium binding increases in an alkalotic state.
📌Core Message
Excessive gastric acid loss leads to metabolic alkalosis, with hypoventilation as the respiratory compensatory mechanism.
