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 B
Explanation
Rationale:
A. Taking the medication 2 hours apart from calcium supplements is important, but the timing is not the primary instruction; the focus should be on the medication itself.
B. Levothyroxine should be taken on an empty stomach, ideally 30 to 60 minutes before breakfast, to enhance absorption.
C. Taking a double dose if a dose is missed can lead to toxicity; patients should be instructed to skip the missed dose and resume the regular schedule.
D. While taking the medication with a small sip of water is acceptable, it is not the most critical instruction for ensuring proper absorption and effectiveness of levothyroxine.
Correct Answer is A
Explanation
Rationale:
A. Initiating the process to review the medical record is appropriate; clients have the right to access their medical information under HIPAA regulations, and the nurse can assist in starting that process.
B. While there are restricted parts of a medical record, the response lacks a proactive approach to assisting the client in accessing the information they have the right to view.
C. This response is dismissive of the client's request and does not provide an avenue for understanding the medical record better.
D. Although the provider can provide more detailed information about treatment, it does not address the client's right to review their own medical record.
