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?

A.

Compensated metabolic acidosis

B.

Compensated respiratory acidosis

C.

Uncompensated respiratory acidosis

D.

Uncompensated metabolic acidosis

Answer and Explanation

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 C

Explanation

Rationale:

A. Applying a cold compress is not recommended for DVT; instead, heat may be more appropriate to alleviate discomfort and improve circulation.

B. Massaging the affected extremity is contraindicated as it can dislodge the clot and lead to complications such as pulmonary embolism.

C. Instructing the client to elevate the affected extremity helps reduce swelling and promote venous return, making it the best action.

D. Assessing pulses proximal to the affected area is important for monitoring circulation, but it is not the primary intervention for managing DVT.

Correct Answer is D

Explanation

Rationale:

A. Decreased heart rate is not typical; children with Kawasaki disease often experience tachycardia.

B. Peeling of the soles of the feet is more commonly observed in the convalescent phase of Kawasaki disease rather than the acute phase.

C. Pain in weight-bearing joints can occur in Kawasaki disease but is not the hallmark symptom during the acute phase.

D. Fever unresponsive to antipyretics is a classic finding in the acute phase of Kawasaki disease, indicating ongoing inflammation and a need for further intervention.
