A nurse is reviewing the ABG results of a client who has COPD. The results include a pH of 7.3 (7.35 to 7.45), PaO2 56 mm Hg (80 to 100 mm Hg), PaCO2 54 mm Hg (35 to 45 mm Hg), HCO3- 26 mEq/L (21 to 28 mEq/L), and SaO2 87%. Which of the following is the correct interpretation of these values?
Compensated metabolic acidosis
Compensated respiratory acidosis
Uncompensated respiratory acidosis
Uncompensated metabolic acidosis
The Correct Answer is C
Rationale:
A. Compensated metabolic acidosis would show a normal pH with a decrease in HCO3- and a decrease in PaCO2.
B. Compensated respiratory acidosis would show a normal pH with an elevated PaCO2 and a compensatory increase in HCO3-.
C. The low pH indicates acidosis, and the elevated PaCO2 suggests that it is respiratory in origin, with the HCO3- remaining normal, indicating no compensation has occurred yet.
D. Uncompensated metabolic acidosis would present with a low pH, low HCO3-, and normal PaCO2.

B. Asking the client's partner to choose their meal removes the client's autonomy and does not facilitate direct communication.
C. While expecting extended time for verbal responses is considerate, it does not provide a practical solution for meal selection.
D. Asking the client to point to items on a picture menu is an effective way to facilitate communication, allowing the client to express their preferences without relying on verbal communication alone.
