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.

Correct Answer is D
Explanation
Rationale:
A. Decreased cholesterol is not a primary effect of chlorpromazine; the medication is primarily used for psychiatric conditions, not lipid management.
B. While chlorpromazine may have sedative effects that could impact blood pressure, decreased blood pressure is not a direct indicator of its effectiveness in treating psychiatric symptoms.
C. Decreased esophageal reflux is not a relevant effect of chlorpromazine, as it is primarily used for managing psychotic symptoms.
D. Decreased hallucinations is a direct indication of the medication's effectiveness in treating conditions such as schizophrenia or other psychotic disorders, as chlorpromazine is an antipsychotic medication.
