WBC count 15,000/mm3

Sodium 130 mg/dL

BUN 8 mg/dL

Hematocrit 35%

Answer and Explanation

The Correct Answer is A

A high WBC count (leukocytosis) indicates an inflammatory response to an infection, such as pneumonia. The nurse should expect to see this value in a client who has pneumonia and monitor the client for signs and symptoms of sepsis or systemic inflammatory response syndrome (SIRS). The other values are within normal or expected ranges for a client who has pneumonia.
