A 78-year-old patient with a fractured hip is scheduled for surgery tomorrow morning. Which nursing intervention is the HIGHEST priority to prevent complications during the preoperative period?

Strict bed rest prevents fracture displacement, which could cause severe vascular or nerve damage. Other interventions (position changes, ice, ambulation) are important but secondary to immobilization.

Understanding the Preoperative Priority
For a 78-year-old patient with a fractured hip awaiting surgery, the highest priority nursing intervention is to maintain strict bed rest and avoid moving the affected leg. This is not merely about comfort; it is a critical safety measure to prevent further injury and a cascade of life-threatening complications before the fracture is surgically stabilized.

Pathophysiology and Rationale for Immobilization
A hip fracture creates an inherently unstable skeletal structure. Any movement of the affected leg—whether active by the patient or passive during repositioning—can displace the fractured bone fragments. This displacement can damage the surrounding richly vascularized tissues, leading to increased hemorrhage and hematoma formation. More critically, the sharp edges of the displaced bone pose a direct threat to the nearby femoral neurovascular bundle, which includes the femoral nerve, artery, and vein. Injury to these structures can result in severe bleeding, nerve damage, or compromised distal circulation. Therefore, preoperatively, the limb must be stabilized, often with temporary traction or by maintaining the leg in a neutral alignment with pillows, to minimize these risks. This intervention directly addresses the immediate physical integrity of the limb and prevents an acute preoperative crisis.

Connecting Immobilization to DVT Risk: A Clinical Paradox
While strict bed rest is the immediate priority, it creates a significant secondary risk: venous stasis, a major component of Virchow's triad for thrombus formation. The research you've provided illuminates this critical perioperative challenge. The study by Hu et al. specifically highlights that the risk of deep venous thrombosis (DVT) evolves dynamically and is often overlooked during the "preoperative waiting period" ^[2]. This means the very intervention required to protect the fracture site simultaneously places the patient on a trajectory toward a potential DVT. The Liu et al. study further validates that older adults with hip fractures are a particularly high-risk group, and their nutritional status can influence DVT incidence ^[1]. This evidence underscores that the preoperative phase is not a passive waiting time but an active period of risk evolution that demands vigilant assessment and prophylactic planning, even while the patient remains on strict bed rest. The nurse's role is to understand this paradox: you must enforce the immobility that prevents acute injury while simultaneously initiating other passive interventions, such as anti-embolism stockings or sequential compression devices, to counteract the resulting venous stasis.

Why the Other Options Are Not the Highest Priority
The other interventions are important but are secondary to preventing further injury from an unstable fracture.
- Encouraging frequent position changes (Option 1) is contraindicated because the movement required to reposition the patient can cause fracture displacement and the complications described above. Pressure ulcer prevention is achieved through other means, such as a specialized mattress and meticulous skin care, without moving the affected hip.
- Applying ice packs (Option 3) is a supportive measure for pain and swelling but does not address the primary threat of neurovascular injury from an unstable fracture. Pain management is crucial but is a lower priority than maintaining skeletal and vascular integrity.
- Assisting the patient to ambulate (Option 4) is absolutely contraindicated before surgery. Weight-bearing on an un-repaired hip fracture would cause severe displacement, pain, and soft tissue damage. Ambulation for DVT prevention is a postoperative goal, not a preoperative one.
