Correct Answer is B

Explanation

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. Apply a warm cloth over the client's eyes. B. Place the client in a supine position. C. Maintain seizure precautions. D. Obtain a prescription for an opioid medication for pain.

Correct Answer is C

Explanation

a. Apply a warm cloth over the client's eyes: This intervention is not typically indicated for a client who had a craniotomy. It is important to monitor for signs of increased intracranial pressure, but a warm cloth over the eyes is not a standard intervention.

b. Place the client in a supine position: The position of the client after a craniotomy will depend on the surgeon's preference. It is important to follow specific postoperative positioning

instructions, which may or may not include supine positioning.

c. Maintain seizure precautions: Seizure precautions are crucial for clients who have had a craniotomy, as they are at an increased risk of seizures postoperatively.

d. Obtain a prescription for an opioid medication for pain: Pain management is important, but opioid medications may be carefully titrated due to the potential for respiratory depression and other side effects. It is not the primary intervention in the immediate postoperative period.
