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 restricting visits from young children may help reduce infection risk, it is not a sufficient or specific intervention for neutropenic precautions.
B. Avoiding raw fruits is critical because they can harbor bacteria and increase the risk of infection in neutropenic clients. Cooked fruits are safer options.
C. Measuring temperature should occur more frequently than every 8 hours, ideally every 4 hours or more, to quickly identify fever, a sign of infection.
D. Disposable gloves should be used from within the client's room to maintain strict infection control measures; using gloves from outside could introduce contaminants.
Correct Answer is A
Explanation
Rationale:
A. Assisting with deep breathing and coughing is the priority action. This is crucial in preventing respiratory complications, such as atelectasis or pneumonia, especially following abdominal surgery. Deep breathing exercises can help expand the lungs and promote ventilation.
B. Monitoring the incision site for signs of infection is important, but it is not the immediate priority. The client’s respiratory function takes precedence in the early postoperative period.
C. Assessing fluid intake is important for overall recovery, but it is not as critical as ensuring the client can breathe effectively and prevent complications.
D. While ambulation is beneficial for recovery and preventing complications such as deep vein thrombosis, the nurse must first ensure the client can manage their airway and breathing.
