Final answer:
The priority nursing intervention for a patient with a fractured femur in skeletal traction is frequent neurovascular assessments of the affected leg to prevent serious and immediate complications such as tissue necrosis and thrombosis.
Step-by-step explanation:
A client who has been admitted with a fractured femur and is in skeletal traction requires comprehensive nursing care. Among the interventions listed, the priority should be given to B) frequent neurovascular assessments of the affected leg. Regular neurovascular checks are critical to detect signs of compromised blood flow or nerve function, which can have serious and immediate consequences, including the risk of tissue necrosis, deep vein thrombosis, and pulmonary embolism, among other complications.
Meanwhile, maintaining proper body alignment, inspecting pin sites, and applying an over-bed trapeze are also important but come after ensuring the neurovascular status is stable and intact. Each aspect of care is significant; however, in the acute phase following a femoral fracture and the placement of skeletal traction, monitoring for circulation, sensation, and movement can prevent life-threatening complications.
