A 65-year-old client with a fractured hip is scheduled for surgery in the morning. Which nursing action is the highest priority to prevent complications during the preoperative period?

Maintaining proper alignment and immobilization of the fractured hip is the highest priority to prevent further displacement, neurovascular compromise, and additional tissue damage before surgery.

Hip fractures in elderly patients require immediate and careful management before surgery to prevent serious complications. The highest priority nursing action is maintaining proper alignment and immobilization of the affected leg. This is crucial because movement or displacement of fracture fragments can lead to serious complications such as neurovascular injury, fat embolism, bleeding, and increased pain.

Proper alignment prevents further damage to surrounding tissues, blood vessels, and nerves. Hip fractures, especially intracapsular fractures, can disrupt blood supply to the femoral head, potentially causing avascular necrosis if not managed properly. Immobilization also reduces the risk of fat embolism syndrome, a potentially life-threatening complication where fat globules from the bone marrow enter the circulation.

The affected leg should be maintained in slight abduction and external rotation, often using traction or special positioning devices. Unnecessary movement should be avoided, and the patient should be educated not to bend the hip or bear weight on the affected side. This positioning helps maintain circulation and prevents further displacement of fracture fragments.

While pain management, respiratory care, and vital sign monitoring are also important aspects of preoperative nursing care, preventing mechanical complications through proper positioning and immobilization takes priority. Maintaining the integrity of the fracture site and preventing displacement takes precedence over other interventions in the immediate preoperative period.

Understanding the Priority: Why Immobilization Comes First

For a client with a fractured hip awaiting surgery, the highest priority nursing action is to maintain the affected leg in proper alignment and immobilization. While all listed interventions are important aspects of preoperative care, this action directly prevents the most immediate and severe complications. A hip fracture is inherently unstable; movement of the bone fragments can injure surrounding neurovascular structures, increase bleeding, and intensify pain. The primary, non-negotiable goal is to stabilize the fracture site to prevent further injury.

Connecting the Evidence to Clinical Practice

The provided evidence underscores why this mechanical stabilization is the foundation of care. A prospective cohort study on perioperative complications in lower extremity fractures highlights a critical insight: the risk for serious events like deep vein thrombosis (DVT) begins to evolve not just after surgery, but during the preoperative waiting period ^[2]. Improper alignment and lack of immobilization can cause direct trauma to the venous endothelium from bone fragments and lead to venous stasis, two key factors in Virchow's triad for thrombus formation. By ensuring proper alignment and immobilization, the nurse actively mitigates this early risk.

Furthermore, this foundational action creates a platform for the success of other interventions. A narrative review on hip fracture management in patients with cognitive impairment emphasizes that early mobilization and rehabilitation are critical yet often hindered by complications like pain and delirium . Effective immobilization and alignment of the fracture are prerequisites for pain control. When bone fragments are not grating against each other, pain is significantly reduced, which in turn can decrease the physiological stress response and lower the risk for postoperative delirium (POD), a common and serious neuropsychiatric complication in elderly orthopedic patients . A client in less pain is also more capable of participating in essential preoperative activities, such as deep breathing and coughing exercises, making those interventions more effective.

Analyzing the Other Options

The other nursing actions, while important, address secondary priorities that are dependent on or less urgent than fracture stabilization.

- Administering prescribed pain medication (Option 2): Pain management is crucial, but it is a symptomatic treatment. Without proper alignment, the source of the pain is unaddressed, and analgesia alone may be insufficient. The priority is to first eliminate the mechanical cause of the pain through proper positioning.
- Encouraging deep breathing and coughing exercises (Option 3): This intervention is vital for preventing postoperative respiratory complications like atelectasis and pneumonia. However, its impact is more long-term and is not the most immediate physiological threat in the acute preoperative phase. A client in severe pain from an unstabilized fracture will not be able to perform these exercises effectively.
- Monitoring vital signs (Option 4): This is a core nursing assessment function. Monitoring every 2 hours is appropriate, but it is a passive surveillance measure. It detects a complication like hemorrhage or embolism after it has occurred. In contrast, maintaining alignment and immobilization is an active, preventive measure that stops a primary cause of such complications from developing in the first place. The nursing process prioritizes interventions that prevent harm over assessments that detect it.
