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.

A. Overusing a muscle while jogging B. Twisting a ligament while walking C. Impact injury on a joint from a fall D. Crush injury to a bone from blunt trauma

Correct Answer is B

Explanation

a. Overusing a muscle while jogging: Overuse injuries are more commonly associated with strains, not sprains. Strains involve the muscles or tendons.

b. Twisting a ligament while walking: This is an example of a mechanism that can lead to a sprain. A sprain involves the stretching or tearing of ligaments, which connect bone to bone.

c. Impact injury on a joint from a fall: This is more likely to result in a sprain, as it can cause damage to ligaments.

d. Crush injury to a bone from blunt trauma: This type of injury is more likely to affect bones rather than ligaments or tendons, and it would not be considered a sprain or strain.
