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. A report of chest pain is an adverse effect of epinephrine, which can increase myocardial oxygen demand and cause angina or myocardial ischemia.
B. Hypotension is not a common effect after administering epinephrine; it typically causes hypertension due to vasoconstriction.
C. Ecchymosis is not a known adverse effect of epinephrine and may be related to other factors.
D. Tinnitus is not a recognized adverse effect of epinephrine and does not commonly occur after administration.
