After a total knee arthroplasty, what neurovascular parameters should the nurse monitor?

Monitoring neurovascular parameters after a total knee arthroplasty is crucial to ensure the proper circulation and function of the leg. The correct answer emphasizes the importance of capillary refill, sensation, color, and pulse.

Capillary refill assesses the perfusion of the tissues and the circulation integrity. Sensation is vital to determine if there is any nerve impairment following the surgery. Observing the color of the limb can reveal any signs of compromised blood flow, while checking the pulse helps in assessing the vascular supply to the leg. Together, these parameters provide a comprehensive overview of the neurovascular status, allowing for early detection of complications such as infection, thrombosis, or other circulatory issues that may arise post-operatively.

Monitoring mobility and strength, while significant for rehabilitation, is not primarily focused on neurovascular status. Observing temperature and color of the other leg does not directly inform the nurse about the surgical leg's condition. Blood pressure and respiratory rate are important vital signs but do not address the specific neurovascular concerns following knee surgery. Therefore, the first option aligns best with the critical aspects of care following total knee arthroplasty.
