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","D","E"]
Explanation
Rationale:
A. Polyuria is not typically associated with immobility; instead, immobility can lead to urinary retention.
B. Contractures of the extremities occur due to prolonged immobility, leading to shortening of muscles and tendons.
C. Diarrhea is not a common complication of immobility; constipation is more frequently seen due to decreased mobility.
D. Crackles in the lungs can develop due to stasis of secretions and respiratory complications related to immobility.
E. Pressure ulcers develop from prolonged pressure on the skin due to immobility, especially over bony prominences.
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.
