A 2-year-old toddler diagnosed with developmental dysplasia of the hip (DDH) is being treated with a Pavlik harness. The parents express concern about caring for their child at home. Which instruction should the nurse prioritize when teaching the parents?
1Remove the harness daily for bathing and skin inspection
2Adjust the harness straps if the infant appears uncomfortable
3Place the infant in a prone position during sleep to prevent hip displacement
4Maintain the harness continuously except during diaper changes as prescribed✓ 정답
해설
Continuous harness wear as prescribed maintains proper hip positioning for effective DDH treatment. Daily removal or prone positioning can disrupt reduction and increase risk of displacement.
Core Nursing ExplanationKey Concept Analysis: This question tests the essential principles of caring for an infant in a Pavlik harness for Developmental Dysplasia of the Hip (DDH). The Pavlik harness is a dynamic splint that holds the infant's hips in a flexed and abducted ("frog-leg") position. This position centers the femoral head within the acetabulum, allowing for proper development. The core principle is continuous wear to maintain this crucial positioning until the hip joint stabilizes.
Answer Rationale: Key Point! The correct answer is to maintain the harness continuously except during diaper changes as prescribed. This is the cornerstone of Pavlik harness therapy. The harness must be worn 23-24 hours a day to be effective. The only exception typically allowed is for brief diaper changes, where the straps at the front may be loosened while keeping the infant's legs in the abducted position. Any unnecessary removal increases the risk of the hip dislocating again, which can lead to treatment failure and the need for more invasive procedures like casting or surgery.
Distractor Analysis: Watch out for confusion! Option ① is incorrect because the Pavlik harness is not to be removed for bathing. The infant is typically sponge-bathed while the harness remains on. Daily removal disrupts the constant corrective force and jeopardizes the treatment's success.
Option ② is incorrect because parents should never adjust the harness straps themselves. The harness is meticulously fitted and adjusted by an orthopedist or trained clinician. Adjusting it based on perceived discomfort can lead to improper positioning, skin breakdown from pressure, or even a dangerous condition like Femoral nerve palsy. Parents should report any signs of discomfort or redness to the healthcare provider.
Option ③ is incorrect and potentially harmful. Placing an infant in a prone position (on the stomach) while in a Pavlik harness can force the hips into an adducted (brought together) position, which is the opposite of the desired abduction. This can displace the hip. Infants in a Pavlik harness should sleep supine (on the back) to maintain safe hip positioning and align with safe sleep practices to prevent SIDS (Sudden Infant Death Syndrome).
Related Concepts: Successful DDH treatment with a Pavlik harness requires a partnership between the healthcare team and the parents. Parental education focuses on three pillars: 1) Harness Integrity (continuous wear, no adjustments), 2) Skin Integrity (checking for redness or breakdown under straps daily during diaper changes), and 3) Proper Positioning (supine sleep, proper car seat use). Non-compliance is a major cause of treatment failure.

Anatomy, Physiology & Pharmacology Points
Anatomy: DDH involves a shallow acetabulum (hip socket) and/or a displaced femoral head. The Pavlik harness positions the hip in flexion (bent) and abduction (spread apart), which is the most stable position for the joint.
Pathophysiology: Without treatment, the malformed joint leads to abnormal wear, early osteoarthritis, leg length discrepancy, and a limp (Trendelenburg gait).
Developmental Window: Treatment is most effective in early infancy due to rapid bone and cartilage growth and plasticity.
Memory Tips
ABCs of Pavlik Harness Care:Always on, Back to sleep, Check skin (don't Change straps!).
Think "Frog": The desired position is like a frog's legs—flexed and abducted. Anything that brings the legs together (adduction) is bad.
Harness Rule: "If it comes off, the treatment is a fail." Emphasize continuity to parents.
High-Frequency NCLEX Topics
DDH and Pavlik harness care is a Core pediatric orthopedic topic. The NCLEX-RN loves to test on parent education and safety. You must know: 1) The principle of continuous wear, 2) That parents should NOT adjust the device, 3) Correct sleeping position (supine), and 4) Key monitoring points (skin integrity, neurovascular checks of feet).
Watch Out for Question Variations!
Instead of asking for teaching, a question might ask: "The nurse observes redness under the strap of a Pavlik harness. What is the priority action?" (Answer: Assess the area, document, and notify the provider. Do NOT remove the harness.)
A question could test on assessment findings of DDH: Asymmetric thigh/gluteal folds, limited hip abduction, Ortolani/Barlow signs (click/clunk).
A question might present a scenario where a parent adjusted the straps and the infant now has a foot drop. This points to femoral nerve palsy from excessive flexion.
Nursing Clinical Practice GuideClinical Scenario: You are a pediatric nurse in an orthopedic clinic. Mrs. Jones brings in her 3-month-old daughter, Mia, who was diagnosed with DDH and fitted with a Pavlik harness one week ago. Mrs. Jones appears anxious and says, "It's so hard to see her in this thing. Her skin looks a little red under one strap, and I just want to take it off to give her a proper bath."
Nursing Intervention Strategy:
1. Assessment & Empathy: First, acknowledge the parent's feelings: "It's completely understandable to feel this way. This is a big adjustment for both of you." Then, perform a focused assessment. With the parent present, carefully check the skin under all harness straps during a diaper change.
2. Education & Re-teaching: Use this as a teachable moment. Reinforce the "why": "The harness needs to stay on constantly to guide Mia's hip socket to grow correctly. Think of it as gently holding her hip in the perfect spot all day and night." Demonstrate sponge bathing techniques around the harness.
3. Skin Care Management: For the red area, instruct the parent to keep the skin clean and dry. A small amount of cornstarch can be used to reduce moisture, but avoid lotions or powders that could cake. Show how to gently shift the skin under the strap (without moving the harness position) to relieve pressure. Emphasize that significant redness, blistering, or skin breakdown must be reported immediately.
4. Evaluation & Support: Ask the parent to demonstrate a diaper change with the harness on. Provide positive feedback. Schedule a follow-up call in 2-3 days to check on skin status and compliance. Connect them with support resources if needed.
Patient Safety and Precautions:
Absolute Contraindication: Never place the infant prone to sleep. This is a dual safety issue (hip displacement and SIDS risk).
Medication/Device Caution: The harness is a medical device. Only the prescribing orthopedic team should adjust it. Tight straps can cause nerve injury; loose straps render treatment ineffective.
Key Monitoring Points: Daily: Skin integrity. At each visit: Hip stability (via exam), harness fit, and neurovascular status of the lower extremities (check for warmth, color, movement, sensation, and pulses in the feet).
Nursing Procedure & Medication FlowProcedure: Performing a Skin Check & Diaper Change with Pavlik Harness
1. Gather supplies: Clean diaper, wipes, washcloth, towel.
2. Position infant supine on a safe, flat surface.
3. Only unfasten the front chest strap and the leg strap connections as per the specific harness design instructions. The shoulder straps and foot pieces often remain fastened.
4. Change the diaper, thoroughly cleaning and drying the skin.
5. Systematically inspect the skin under each strap (chest, shoulders, thighs, calves) for redness, irritation, or breakdown.
6. Re-fasten the straps exactly as they were, ensuring the infant's legs remain in the proper flexed and abducted position.
7. Document findings and any parent education provided.
A Word from Your Senior Nurse
Caring for a baby in a Pavlik harness is one of those times where nursing empathy meets strict clinical science. Your role is to be the bridge between the anxious parents and the rigid requirements of the treatment. Remember, your calm, confident teaching can make all the difference in compliance. When you explain why the harness must stay on, you're not just giving an order—you're empowering parents to be partners in their child's care. That trust and understanding you build is what turns a stressful treatment into a successful outcome. On the NCLEX, they're testing if you know the non-negotiable rules (continuous wear, no adjustments) and the compassionate way to enforce them.
