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. Early decelerations are typically benign and often associated with head compression, not necessitating an emergency cesarean birth.
B. A knee-chest position is generally used for variable decelerations but is not indicated for early decelerations.
C. Continuous internal monitoring may be necessary in certain situations, but in the case of early decelerations, it is not an immediate intervention.
D. Early decelerations usually require continued monitoring without immediate intervention as they typically resolve spontaneously with contractions.
Correct Answer is B
Explanation
Rationale:
A. Surgical asepsis (sterile technique) should be used for suctioning to prevent infection, not medical asepsis.
B. Applying suction for no longer than 10 seconds is appropriate to prevent hypoxia and trauma to the airway.
C. Advancing the catheter 2 cm after resistance is met is not advised; the catheter should not be forced beyond resistance to avoid injury.
D. The catheter should not be withdrawn if the client begins coughing; instead, it indicates the need for suctioning. If coughing occurs, the nurse should ensure the patient can breathe and may need to suction carefully.
