Question

A client scheduled for an arthroscopic knee replacement has a serum potassium of 5.9 mEq/L. The physical assessment does not show any alterations in status. What is the nurse's best action?

a. Call the doctor; the lab is abnormal.
b. Ask the lab to re-draw the potassium level.
c. Call the operating room, and alert the charge nurse.
d. Continue with the current plan of care.

Answer 1

The nurse should call the doctor to report the abnormal serum potassium level, request a re-draw to confirm hyperkalemia, and follow the doctor's orders regarding the surgery.

Step-by-step explanation:

A serum potassium level of 5.9 mEq/L is considered higher than normal and falls under the condition known as hyperkalemia. Although the patient does not present with physical signs of hyperkalemia, which can impair the function of skeletal muscles, the nervous system, and be particularly dangerous for the heart, it is important to ensure the accuracy of lab results before proceeding with an invasive procedure such as a knee replacement. Therefore, the nurse's best action would be to:

Call the doctor; report the abnormal lab value immediately.

Request a re-draw of the potassium level to confirm hyperkalemia.

Based on physician's orders, implement any necessary interventions, such as holding or delaying the surgery if verified.

Following these steps helps ensure patient safety and optimizes care outcomes.
