Correct Answer is A
Explanation
A. Respiratory acidosis: The pH is low (indicating acidosis), and the Paco₂ is elevated, which signifies that carbon dioxide retention is causing the acidosis. This pattern indicates respiratory acidosis, as the elevated HCO₃ suggests a compensatory response.
B. Respiratory alkalosis: Respiratory alkalosis would show a high pH with a low Paco₂. This is not consistent with the client’s lab results.
C. Metabolic acidosis: Metabolic acidosis would show a low pH with a low HCO₃. In this case, the HCO₃ is slightly elevated, ruling out metabolic acidosis.
D. Metabolic alkalosis: Metabolic alkalosis would show a high pH with an elevated HCO₃, which does not match the client’s results.
