A nurse is reviewing the diagnostic test results of a female client who is about to undergo knee arthroplasty. Which of the following data collection findings should the nurse identify as the priority?

Creatinine 0.9 mg/dL

WBC count 20,000/mm3

Potassium 3.8 mEq/L

Hematocrit 40%

Answer and Explanation

The Correct Answer is B

a. Creatinine 0.9 mg/dL: This creatinine level is within the normal range and is not an immediate priority for knee arthroplasty.

b. WBC count 20,000/mm3: An elevated white blood cell count suggests the presence of

infection or inflammation. In the context of knee arthroplasty, infection is a significant concern and requires immediate attention to prevent complications.

c. Potassium 3.8 mEq/L: This potassium level is within the normal range and is not an immediate priority for knee arthroplasty.

d. Hematocrit 40%: This hematocrit level is within the normal range and is not an immediate priority for knee arthroplasty. The elevated WBC count takes precedence as it suggests a

potential infectious process.
