A client who has been experiencing prolonged vomiting has the following ABG results: pH 7.48;
pCO2 40 mm Hg; HCO3 34 mEq/L; pO2 85 mm Hg. The nurse determines that the client is
experiencing which of the following imbalance?
Select one:
a. Respiratory Alkalosis
b. Metabolic Alkalosis
c. Respiratory Acidosis
d. Metabolic Acidosis answer- b. Metabolic Alkalosis
Alkalosis is reflected by an arterial pH greater than 7.45. Because this client has an increase in
the base component, HCO3, this is a metabolic alkalosis.
Metabolic alkalosis results from:
• Base excess
- Oral ingestion of bases (antacids)
- Venous administration of bases (blood transfusions, TPN, or sodium bicarbonate)
- Acid deficit
- Loss of gastric secretions (through prolonged vomiting, NG suction)
- Potassium depletion (due to thiazide diuretics, laxative abuse, Cushing's syndrome)
- Metabolic alkalosis results in:
- Increased HCO3
