A 55-year-old patient with a history of osteoporosis is admitted after a motor vehicle accident and sustaining a displaced intertrochanteric hip fracture. The patient is scheduled for emergency surgery within 3 hours, reports moderate pain (6/10), and is restless. What is the nurse's highest priority intervention in the immediate preoperative period?

Frequent neurovascular assessment every 15 minutes is the highest priority to detect early signs of complications like compartment syndrome or avascular necrosis that can lead to permanent disability. Other interventions are important but do not address this immediate threat.

Understanding the Priority: Immediate Preoperative Care for Hip Fracture

In the immediate preoperative period for a patient with a displaced hip fracture, the nurse's highest priority is to prevent complications that can directly impact surgical and overall outcomes. While pain management and patient education are essential, the risk of neurovascular compromise due to the displacement of the fracture and associated muscle spasm is an immediate physiological threat. The primary goal is to preserve the limb's viability and function by ensuring adequate blood flow and nerve function.

Why Assessing Neurovascular Status is the Priority

A displaced intertrochanteric or femoral neck fracture involves a break in the continuity of the bone, often with sharp, mobile fragments. These fragments, combined with the significant force from the injury and subsequent muscle spasm, can compress, kink, or lacerate adjacent blood vessels and nerves. The primary concern is compromise to the profunda femoris artery and its branches, which supply the femoral head and neck, as well as the sciatic and femoral nerves. Compromised circulation can rapidly lead to tissue ischemia, avascular necrosis of the femoral head, and potential limb loss. Neurological injury can result in permanent motor and sensory deficits. Frequent neurovascular assessments, as often as every 15 minutes for an acutely injured limb with a displaced fracture, allow the nurse to detect early, subtle changes such as diminished pulses, pallor, paresthesia, or increasing pain, which would necessitate immediate escalation to the surgical team .

The Role of Pain and Delirium Prevention

The patient's reported pain (6/10 to 8/10) and restlessness are significant findings that must be addressed, but they are secondary to a primary neurovascular assessment. Uncontrolled pain is not just a comfort issue; it is a physiological stressor that can increase the risk of postoperative delirium (POD), a serious complication that is a predictor of mortality in hip fracture patients [1,2]. The use of opioid medications, while common for pain relief, paradoxically increases the incidence of delirium in the pre- and postoperative periods ^[1]. This creates a clinical challenge. The evidence strongly supports the use of regional nerve blocks, such as a fascia iliaca compartment block, as an effective opioid-sparing strategy for acute pain management in hip fractures [1,4]. A study by Duan et al. demonstrated that combining general anesthesia with an ultrasound-guided iliac fascia compartment nerve block improved hemodynamic stability and recovery in elderly hip surgery patients . While administering prescribed pain medication (option 2) is important, the nurse must first establish a baseline neurovascular status and ensure no acute compartment syndrome or vascular injury is masked by the analgesia. The priority remains the neurovascular assessment, after which pain interventions, ideally including a regional block, can be safely implemented.

Analysis of Other Options

- Option 2: Administer prescribed pain medication to achieve comfort. This is a high priority but not the highest. Pain management is critical to reduce the stress response and delirium risk, but a thorough assessment must precede the administration of analgesics to avoid masking a deteriorating neurovascular condition. The optimal pain strategy, supported by evidence, would be a regional nerve block to minimize opioid use and its associated delirium risk [1,2].
- Option 3: Provide detailed preoperative teaching about the surgical procedure. While patient education is a core nursing responsibility, it is not the immediate priority for a restless patient in acute pain who is facing emergency surgery in 2-3 hours. The patient's anxiety and pain will severely limit their ability to process detailed information. A brief, focused explanation and emotional support are more appropriate at this moment.
- Option 4: Position the patient in high Fowler's position to prevent aspiration. This position is contraindicated for a patient with an acute, displaced hip fracture. High Fowler's position places excessive hip flexion and stress on the fracture site, potentially worsening displacement, increasing pain, and further compromising neurovascular status. The patient should be maintained in the position of most comfort, typically supine with the affected limb in neutral alignment, often with a pillow or splint for immobilization. Pre-operative traction, while historically used, has not been shown to provide superior pain relief compared to simple splinting and positioning, as indicated by a meta-analysis on the subject .
