Correct Answer is A

Explanation

A. The low pH (below the normal range of 7.35-7.45) indicates acidosis. The elevated PaCO2 (above the normal range of 35-45 mm Hg) suggests respiratory involvement, indicating respiratory acidosis.
B. Metabolic acidosis is characterized by a low pH and low HCO3, not an elevated PaCO2.
C. Respiratory alkalosis is characterized by a high pH and low PaCO2.
D. Metabolic alkalosis is characterized by a high pH and high HCO3.

A. Metabolic acidosis B. Metabolic alkalosis C. Respiratory alkalosis D. Respiratory acidosis

Correct Answer is B

Explanation

A. Severe vomiting can lead to a loss of gastric acid, resulting in metabolic alkalosis and not acidosis.
B. A client who is experiencing severe nausea and vomiting may lose gastric acid through vomitus and develop metabolic alkalosis, which is a condition characterized by a high pH (greater than 7.45) and a high bicarbonate (greater than 26 mEq/L). Metabolic alkalosis can cause confusion, tremors, tetany, and hypokalemia.
C. Respiratory alkalosis is not typically associated with vomiting; it is more often seen in conditions with hyperventilation.
D. Respiratory acidosis is not the primary acid-base imbalance associated with vomiting; it is more commonly associated with conditions affecting lung function.
