A patient's blood gases show a pH of 7.53 and bicarbonate level of 36 mEq/L. The nurse realizes that the patient is demonstrating which acid?base disorder?
1. respiratory acidosis
2. metabolic acidosis
3. respiratory alkalosis
4. metabolic alkalosis
Correct Answer: 4
Arterial blood gases (ABGs) show a pH greater than 7.45 and bicarbonate level greater than 26 mEq/L when the patient is in metabolic alkalosis. Respiratory and metabolic acidosis are both consistent with pH less than 7.35. Respiratory alkalosis is associated with a pH greater than 7.45 and a PaCO2 of less than 35 mmHG. It is caused by respiratory related conditions.
