A.

Temperature

B.

Respirations

C.

Blood pressure

D.

Heart rate

Answer and Explanation

The Correct Answer is D

A. The tympanic temperature of 37.1° C (98.8° F) is within normal limits and does not require re-measurement.  

 

B. The respiratory rate of 14/min is also within the normal range (12-20 breaths per minute).

Correct Answer is A

Explanation

A. Respiratory acidosis: The pH is low (indicating acidosis), and the Paco₂ is elevated, which signifies that carbon dioxide retention is causing the acidosis. This pattern indicates respiratory acidosis, as the elevated HCO₃ suggests a compensatory response.

B. Respiratory alkalosis: Respiratory alkalosis would show a high pH with a low Paco₂. This is not consistent with the client’s lab results.

C. Metabolic acidosis: Metabolic acidosis would show a low pH with a low HCO₃. In this case, the HCO₃ is slightly elevated, ruling out metabolic acidosis.

D. Metabolic alkalosis: Metabolic alkalosis would show a high pH with an elevated HCO₃, which does not match the client’s results.

Correct Answer is D

Explanation

A. Rounded describes a normal abdomen but does not convey the greater extent of fullness seen in this case.

B. Scaphoid describes a concave abdomen, which does not apply to this situation.

C. Flat indicates no significant contour changes, which does not apply here.

D. Protuberant is the correct term, as it describes an abdomen that is significantly distended and is characteristic of conditions like pregnancy, ascites, or obesity.
