Core Nursing Explanation
Key Concept Analysis: This question assesses the priority nursing intervention for a patient with a
displaced femoral neck fracture awaiting surgery. The core principle is
preventing further injury and complications. A displaced fracture means the bone fragments are not aligned, and any movement can cause further displacement, damage surrounding blood vessels, or increase the risk of
avascular necrosis (AVN) of the femoral head. The priority is to
Key Point! immobilize the affected limb and maintain the patient on strict bed rest until definitive surgical stabilization is performed.
Answer Rationale: Option ④ is correct because it directly addresses the primary safety concern: preventing further harm.
Key Point! "Maintain strict bed rest and provide toileting assistance" ensures the fractured hip is immobilized. The nurse should provide a bedpan or urinal and assist the patient with all activities of daily living (ADLs) to eliminate any weight-bearing or significant movement of the affected limb.
Distractor Analysis:
Watch out for confusion! Option ① (ambulate with a walker) is contraindicated. For a displaced fracture, the patient is typically non-weight-bearing (NWB) on the affected leg. Ambulation could cause severe pain, further displacement, and vascular injury.
Option ② (use bedpan while lying flat) is partially correct in using a bedpan but incorrect in encouraging voiding while lying flat. For many patients, especially older adults, voiding in a supine position is difficult and can lead to urinary retention. The nurse should assist the patient into a slight side-lying position (with proper support to the affected leg) to facilitate voiding, if possible, while still maintaining bed rest.
Option ③ (sit up and use commode) involves sitting up and transferring, which requires significant hip flexion and movement. This action could displace the fracture fragments and is not safe pre-operatively for a displaced fracture.
Related Concepts: The management of a hip fracture involves the
RICE principle (Rest, Ice, Compression, Elevation) in the acute phase, with Rest being paramount. Pre-operative care focuses on pain management, prevention of complications (e.g., deep vein thrombosis (DVT), skin breakdown), and preparing the patient physically and psychologically for surgery. Post-operative care will then focus on early mobilization
after the joint is surgically stabilized.
Concept Summary
| Concept | Key Takeaway |
|---|
| Displaced Fracture | Bone fragments are out of alignment. Movement can worsen displacement and cause complications. |
| Pre-op Hip Fracture Care | Priority is immobilization (traction, strict bed rest) to prevent further injury until surgery. |
| Avascular Necrosis (AVN) | A major complication of femoral neck fractures due to disrupted blood supply to the femoral head. |
| Nursing Priority (Safety) | Always prioritize interventions that prevent harm. Do not move a fractured limb before stabilization. |
Side-by-Side Comparison!
| Scenario | Priority Intervention | Rationale |
|---|
| Displaced Femoral Neck Fracture (Pre-op) | Strict bed rest, immobilization, provide bedpan/urinal. | Prevent further displacement, vascular injury, and AVN. |
| Post-op Total Hip Replacement (Day 1) | Ambulate with physical therapy (PT), adhering to hip precautions (e.g., no flexion >90°). | Prevent DVT, pneumonia, and promote healing. The joint is now surgically stabilized. |
| Patient with Severe Pain & Urge to Void (General) | Address pain first (medicate), then assist with toileting. | Pain can inhibit voiding. However, in this fracture case, safety (immobilization) overrides the typical sequence. |
Anatomy, Physiology & Pharmacology Points
The
femoral neck is a common fracture site in older adults, especially those with osteoporosis. Its blood supply is tenuous; the
medial femoral circumflex artery is the primary source for the femoral head. A displaced fracture can tear this artery, leading to
avascular necrosis. Pharmacologically, pain management is crucial. The nurse would anticipate administering IV opioids (e.g., morphine) pre-operatively, while monitoring for respiratory depression.
Memory Tips
FRACTURE Priority Pre-Op: Fix the limb (immobilize),
Restrict movement,
Assess neurovascular status,
Control pain,
Toileting in bed,
Urgent surgery prep,
Risk reduction (DVT prophylaxis),
Educate on bed rest.
Think: "
Don't Move the Broken Bone!" Before surgery, the bone is unstable. After surgery, the new joint is stable, so you move.
High-Frequency NCLEX Topics
This integrates
prioritization (safety first),
musculoskeletal nursing, and
pre-operative care. NCLEX loves to test when to mobilize vs. when to immobilize. Remember:
Key Point! For acute, unstable injuries (displaced fractures, spinal cord injury risk), immobilize. For post-op or chronic conditions (COPD, post-op), mobilize to prevent complications.
Watch Out for Question Variations!
* Instead of toileting, the question could ask about
pain management: "The patient reports severe pain. Which action should the nurse take first?" Answer:
Medicate for pain as ordered (while maintaining bed rest).
* The scenario could shift to
post-operative day 1: "What is the priority intervention?" Answer would then focus on
ambulation and DVT prevention.
* It could test
complication recognition: "Which finding requires immediate notification?" Answer: Signs of
compartment syndrome (e.g., severe pain, pallor, paresthesia) or
fat embolism syndrome (e.g., dyspnea, confusion, petechiae).
