A 7-year-old child with Legg-Calvé-Perthes disease is being discharged home after initial treatment. Which instruction should the nurse prioritize when teaching the parents about home care management?
1Encourage high-impact activities like running and jumping to strengthen the hip muscles
2Apply heat packs to the affected hip for 30 minutes three times daily to reduce pain
3Maintain activity restrictions and use assistive devices as prescribed to protect the hip joint✓ 정답
4Administer aspirin regularly for anti-inflammatory effects and pain management
해설
Activity restriction and assistive device use are prioritized to protect the femoral head during healing in Legg-Calvé-Perthes disease. Other options (high-impact activities, heat application, aspirin) are contraindicated or less critical.
Core Nursing ExplanationKey Concept Analysis: This question assesses your understanding of the core management principles for Legg-Calvé-Perthes disease (LCPD). LCPD is an idiopathic avascular necrosis (AVN) of the femoral head in children. The primary pathophysiological problem is a temporary loss of blood supply to the femoral head epiphysis, leading to bone death, collapse, and potential deformity during the healing process. The overarching goal of treatment is to Key Point!contain the femoral head within the acetabulum to allow for revascularization and remodeling into a spherical shape, thereby preventing long-term osteoarthritis.
Answer Rationale: The correct answer is to Maintain activity restrictions and use assistive devices as prescribed to protect the hip joint. This is the cornerstone of conservative management. Containment is achieved by limiting weight-bearing forces and shear stress on the fragile femoral head. This often involves the use of crutches, a walker, or braces (e.g., an abduction brace) to keep the hip in an abducted and internally rotated position, ensuring the acetabulum acts as a mold for the healing bone. This instruction is the priority because it directly addresses the disease's pathophysiology and prevents the most significant complication: permanent deformity.
Distractor Analysis:
Watch out for confusion! Option ①, encouraging high-impact activities, is contraindicated. Activities like running and jumping increase mechanical stress and compression on the avascular femoral head, which can worsen collapse and deformity.
Option ②, applying heat packs, is generally not recommended for managing LCPD pain. While warmth might provide temporary comfort, it does not address the underlying ischemia. More importantly, heat can increase blood flow to the surrounding tissues but not necessarily to the necrotic area, and it is not a standard of care. Pain management is secondary to joint protection.
Option ④, administering aspirin regularly, is contraindicated due to the risk of Reye's syndrome, a rare but severe condition causing swelling in the liver and brain, which is associated with aspirin use in children and adolescents recovering from viral illnesses. Non-aspirin analgesics like acetaminophen are preferred for pain management.
Related Concepts: Nursing care for LCPD focuses on containment, pain management, maintaining mobility within limits, and supporting the child's psychosocial and developmental needs during a prolonged treatment period (often 2-4 years). Physical therapy is crucial for maintaining range of motion and muscle strength without bearing weight.

Primary Goal
Containment of the femoral head within the acetabulum to allow spherical remodeling.
Core Intervention
Activity restriction & use of assistive devices (crutches, braces) to minimize weight-bearing.
Pain Management
Use acetaminophen or ibuprofen (NSAID). Avoid aspirin in children.
Nursing Focus
Family education, safety, promoting normal development, and adherence to activity limits.
Side-by-Side Comparison!
Condition
Legg-Calvé-Perthes Disease
Slipped Capital Femoral Epiphysis (SCFE)
Age Group
Younger children (4-8 years)
Older children/adolescents (10-16 years), often obese
Pathophysiology
Avascular necrosis (ischemia) of the femoral head.
Displacement (slippage) of the femoral head epiphysis off the metaphysis.
Immediate surgical stabilization (pinning) to prevent further slippage.
Nursing Priority
Educate on long-term activity restriction and device use.
Prepare for urgent surgery, post-op neurovascular checks, non-weight-bearing.
Anatomy, Physiology & Pharmacology PointsAnatomy: The femoral head epiphysis is the growing end of the thigh bone that fits into the hip socket (acetabulum). Its blood supply is vulnerable to interruption. Physiology: The disease progresses through stages: ischemia/necrosis → fragmentation/collapse → reossification/healing → remodeling. Protection is critical during the fragmentation stage. Pharmacology: Key Point! Avoid aspirin in children due to Reye's syndrome risk. Use acetaminophen or other NSAIDs like ibuprofen for pain/inflammation.
Memory TipsLCPD = "Let Child's Pelvis Develop" (emphasizes containment for proper development). The 4 A's of Contraindications in LCPD: Avoid Aspirin, Avoid Activity (high-impact), Avoid Axial loading (weight-bearing), Avoid missing appointments.
High-Frequency NCLEX Topics
NCLEX often tests the priority intervention for chronic pediatric orthopedic conditions. For LCPD, the focus is always on joint protection and containment, not aggressive exercise or inappropriate medications. Be ready to identify contraindicated actions.
Watch Out for Question Variations!
* Instead of discharge teaching, the question might ask: "The nurse is developing a care plan. Which nursing diagnosis is priority?" (Answer: Risk for injury related to impaired bone integrity).
* It could present a scenario where the child wants to play sports: "Which response by the nurse is best?" (Answer: Explain the need to avoid high-impact activities to protect the hip).
* It might combine with medication knowledge: "Which analgesic is contraindicated for this child?" (Answer: Aspirin).
Nursing Clinical Practice GuideClinical Scenario: You are the pediatric nurse preparing for the discharge of 7-year-old Liam, diagnosed with Legg-Calvé-Perthes disease affecting his right hip. He has been fitted for an abduction brace and will be using forearm crutches. His parents are anxious about keeping him safe and engaged at home.
Nursing Intervention Strategy:
1AssessmentAssess the family's home environment (stairs, tripping hazards), their understanding of the disease, and Liam's ability to use crutches. Evaluate his pain level using a pediatric pain scale.
2Education & Implementation* Brace/Crutch Care: Demonstrate proper application of the abduction brace. Teach crutch walking (non-weight-bearing on the right leg). Emphasize never walking without devices.
* Activity Modification: Collaborate to identify safe activities (swimming with supervision once cleared, board games, reading). Explicitly prohibit running, jumping, contact sports, and trampolines.
* Pain Management: Instruct on administering acetaminophen or ibuprofen as ordered for pain. Reinforce the aspirin warning.
* Skin Care: Teach daily skin checks under brace straps for redness or breakdown.
* Follow-up: Stress the importance of all orthopedic follow-up appointments to monitor healing via X-ray.
3EvaluationFollow-up call to assess adherence, device use, pain control, and identify any problems like skin issues or frustration.
Nursing Procedure & Medication FlowAssistive Device Education:
* Crutch Fitting: Ensure 2-3 finger widths between armpit and crutch pad when standing.
* Gait Training: Teach the "swing-through" gait for non-weight-bearing. Practice on level ground and stairs (up with the good leg first, down with the bad leg first).
* Safety: Remove throw rugs, ensure good lighting, and use a backpack for carrying items.Medication Administration:
* Drug of Choice: Ibuprofen 5-10 mg/kg/dose every 6-8 hours PRN pain (max daily dose 40 mg/kg).Contraindication: Aspirin.
* Administration Tip: Give with food or milk to minimize GI upset from ibuprofen.
A Word from Your Senior Nurse
"Managing a chronic condition like Perthes disease is a marathon, not a sprint, for the child and the family. Your role is to be their coach and cheerleader. Empowering the parents with clear, practical 'do's and don'ts' is what will keep that femoral head safe for the next two years. Remember, you're not just teaching about a brace; you're helping a kid navigate childhood without being able to run with his friends. Your empathy and creative ideas for safe play are just as important as your clinical knowledge. On the NCLEX, they're testing that you know the 'why' behind the restriction—protect the bone to prevent a lifetime of hip problems. In real life, you're the one who makes that restriction manageable."
