A 45-year-old construction worker is brought to the emergency department after falling from scaffolding and landing on his right side. He reports severe pain in his right hip, is unable to bear weight, and presents with obvious distress while holding his right leg in a specific position on the stretcher. Which assessment finding would be most indicative of a hip fracture?

Hip fractures typically cause the affected leg to appear shorter with external rotation due to muscle spasm and bone displacement. Other positions like internal rotation or leg lengthening are not characteristic of hip fractures.

Core Nursing Explanation Key Concept Analysis: This question assesses the classic clinical sign of a hip fracture, specifically a femoral neck or intertrochanteric fracture. The mechanism involves the pull of powerful hip muscles after the bone breaks. The iliopsoas muscle, which flexes and externally rotates the hip, goes into spasm, pulling the distal fragment (the leg) into external rotation. Furthermore, the proximal fragment (the femoral head/neck) can be displaced, causing the leg to appear shorter due to the overriding of bone fragments or muscle pull. This combination is a hallmark finding.

Answer Rationale: Key Point! The correct answer is Right leg appears shorter than the left leg with external rotation. This is the classic presentation for a displaced hip fracture. The shortening occurs due to bone displacement and muscle spasm, and the external rotation is caused by the unopposed pull of the iliopsoas and other external rotator muscles. This finding, combined with the mechanism of injury (fall from height), inability to bear weight, and severe pain, strongly confirms the diagnosis.

Distractor Analysis:
Watch out for confusion! Option ① (longer with external rotation) is incorrect. While external rotation is correct, a hip fracture does not cause true leg lengthening. Apparent lengthening is more characteristic of a posterior hip dislocation, where the femoral head is displaced posteriorly.
Option ② (normal length with internal rotation) is incorrect. Internal rotation is not typical for a hip fracture. A normal leg length would be unlikely with a displaced fracture causing significant pain and deformity.
Option ④ (longer with internal rotation) is incorrect for both reasons. Internal rotation is atypical, and lengthening is associated with dislocations, not fractures.

Related Concepts: This assessment is part of the neurovascular check for extremity injuries. For any suspected fracture, nurses must also assess for the "6 Ps" (Pain, Pallor, Pulselessness, Paresthesia, Paralysis, Poikilothermia) to monitor for compartment syndrome or neurovascular compromise. Hip fractures are common in the elderly from low-energy falls (osteoporosis) but can occur in any age group from high-energy trauma, as in this case.
Concept Summary Hip Fracture Classic Signs: Shortening + External Rotation of the affected limb.
Mechanism: Muscle spasm (iliopsoas) and bone displacement.
Key Assessment: Neurovascular status (6 Ps), pain management, and pre-operative care.
Side-by-Side Comparison!

Condition	Leg Position	Mechanism/Key Feature
Hip Fracture (Femoral Neck)	Shortened, Externally Rotated	Muscle spasm (iliopsoas) pulls distal fragment. Bone fragments override.
Posterior Hip Dislocation	Shortened, Internally Rotated	Femoral head is forced out of the acetabulum posteriorly (common in car accidents).
Anterior Hip Dislocation	Lengthened, Externally Rotated	Femoral head is displaced anteriorly, causing apparent lengthening.

Anatomy, Physiology & Pharmacology Points Anatomy: The hip is a ball-and-socket joint. Fractures often occur at the femoral neck or intertrochanteric region. The iliopsoas muscle inserts on the lesser trochanter.
Physiology: Muscle spasm is a protective reflex following fracture, but it causes deformity.
Pharmacology: Pain management is critical. Opioids (e.g., morphine) are often used initially, but NSAIDs may be contraindicated due to bleeding risk. Prophylactic anticoagulants (e.g., enoxaparin) are standard to prevent DVT (Deep Vein Thrombosis) post-fracture.
Memory Tips Mnemonic for Hip Fracture: "Short and Extraverted" (Shortened, Externally Rotated).
Association: Think of the leg "rolling out" (external rotation) and "pulling up" (shortening) due to the powerful hip flexor muscles going into spasm.
High-Frequency NCLEX Topics Hip fracture assessment and post-operative care are high-yield. The NCLEX loves to test the classic signs (shortening/external rotation), priority nursing interventions (pain management, neurovascular checks, turning/positioning), and major complications (DVT, infection, dislocation post-arthroplasty, confusion in elderly).
Watch Out for Question Variations! The same concept can be tested as:
1. Priority Action: "The nurse's first action after finding a post-op total hip replacement patient with a shortened, internally rotated leg is?" (Answer: Suspect dislocation, notify surgeon, prevent further movement).
2. Patient Education: "Which instruction is most important for a patient with a new hip fracture to prevent complications?" (Answer: Use incentive spirometer to prevent atelectasis/pneumonia, or perform ankle pumps to prevent DVT).
3. Complication Identification: Linking the mechanism (fall) to potential associated injuries (e.g., head injury, other fractures).

Nursing Clinical Practice Guide Clinical Scenario: You are the triage nurse in the ED. A 45-year-old male is brought in via ambulance after a 10-foot fall at a construction site. He is alert, yelling in pain, and holding his right leg which is visibly deformed—appearing shorter and turned outward compared to the left.

Nursing Intervention Strategy:
1. Primary Survey (ABCs): Ensure airway, breathing, and circulation are intact. A high-energy fall can cause multi-system trauma.
2. Immediate Stabilization: Do not attempt to "straighten" the leg. Immobilize it in the position of comfort to prevent further neurovascular injury or displacement.
3. Comprehensive Assessment:
- Pain: Assess using a pain scale. Administer prescribed analgesics promptly.
- Neurovascular Status: Perform a systematic check of the "6 Ps" on the affected limb. Compare to the unaffected side.
- Skin: Check for open wounds (open fracture) or bruising.
- Other Injuries: Perform a full head-to-toe assessment. Check spine, pelvis, and contralateral limb.
4. Diagnostic Support: Prepare for X-rays (AP pelvis and cross-table lateral hip views). Anticipate the need for IV access, labs, and possibly a CT scan.
5. Pre-operative Care: If surgery is planned (common for displaced fractures), initiate pre-op protocols: NPO (Nothing by Mouth) status, skin prep, education, and DVT prophylaxis as ordered.

Patient Safety and Precautions:
- Movement: Use log-rolling technique if the patient needs to be moved for bedpan or linen changes to maintain alignment.
- Medication: Be cautious with sedating analgesics until a full neurological assessment is complete. Monitor for respiratory depression.
- Complication Vigilance: Monitor closely for signs of Fat Embolism Syndrome (FES)—a risk with long bone fractures. Key early signs include hypoxemia, confusion, and petechial rash.
Nursing Procedure & Medication Flow Neurovascular Assessment (6 Ps) Procedure:
1. Pain: Location, severity (0-10 scale), quality.
2. Pallor: Compare skin color. Capillary refill > 3 seconds is abnormal.
3. Pulselessness: Palpate distal pulses (dorsalis pedis, posterior tibial). Use Doppler if needed.
4. Paresthesia: "Can you feel me touching your toes?" Check light touch sensation.
5. Paralysis: "Can you wiggle your toes?" Assess motor function.
6. Poikilothermia: Compare skin temperature. Coolness may indicate circulatory compromise.

Medication Administration:
- Analgesia: IV opioids (e.g., morphine) are first-line for severe pain. Titrate slowly to effect while monitoring respirations.
- Anticoagulation: Subcutaneous low-molecular-weight heparin (e.g., enoxaparin) is often started pre-op. Administer in the abdomen, rotating sites. Monitor for bleeding.
A Word from Your Senior Nurse "In trauma, what you see is just the tip of the iceberg. That shortened, externally rotated leg screams 'hip fracture,' but your nursing brain must immediately jump to 'what else could be wrong?' Did he hit his head? Is his pelvis stable? Is he bleeding internally? Your focused assessment on the obvious injury is crucial, but never let it blind you to the rest of the patient. And remember, your calm, efficient care in those first chaotic minutes in the ED—managing pain, protecting the injury, and thoroughly assessing—sets the stage for everything that follows. That's the art and science of nursing."
