The nurse reviews the arterial blood gas results of a client and notes the following:
pH 7.45, [normal range: 7.35-7.45]
Paco2 of 30 mm Hg (30 mmol/L), [normal range: 35-45]
HCO3- of 20 mEq/L (20 mmol/L), [normal range: 22-26]
Which condition would the nurse analyze these results to indicate?
Metabolic alkalosis
Metabolic acidosis
Respiratory alkalosis
Respiratory acidosis
Metabolic acidosis
The Correct Answer is C
A. Metabolic alkalosis is characterized by a high pH and a high HCO3- level; this does not match the provided values.
B. Metabolic acidosis would show a low pH and a low HCO3-, which does not match the findings.
C. The pH is high (7.45) while the Paco2 is low (30 mm Hg), indicating respiratory alkalosis. The low HCO3- could be a compensatory mechanism but does not change the primary interpretation of respiratory alkalosis.
D. Respiratory acidosis would be indicated by a low pH and a high Paco2, which is not the case here.
