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. While a home health nurse visit is important, it is not an immediate safety concern for the client's discharge.
B. The need for assistance when transferring is critical information as it directly impacts the client's safety during discharge; the oncoming nurse must ensure proper support is arranged.
C. The fact that the client's partner will bring clothes is relevant but does not affect the immediate care of the client.
D. Encouragement for personal hygiene is important but is not as urgent as ensuring the client can safely transfer without risk of falls or injury.
Correct Answer is B
Explanation
Rationale:
A. While assessing pain level is important for comfort management, it is not the highest priority in the immediate postpartum period.
B. The amount of vaginal bleeding is critical to assess during the fourth stage of labor to identify potential postpartum hemorrhage, especially with oxytocin administration.
C. Although urinary output is important to monitor for bladder distension, it does not take precedence over bleeding assessment.
D. Fundal height assessment is necessary to ensure the uterus is contracting effectively, but again, it is secondary to monitoring for bleeding.
