해설
Preventing hip flexion contractures is the priority to ensure future prosthetic use and mobility. Pain management and edema control are important but do not prevent this serious, irreversible complication.
Core Nursing Explanation
This question tests the priority nursing intervention for a patient in the early postoperative phase following a Below-Knee Amputation (BKA). The key is understanding the timeline of care and the hierarchy of complications, where preventing a permanent, mobility-limiting issue takes precedence over managing temporary symptoms.
Key Concept Analysis
The core theme is Postoperative positioning and contracture prevention. After an amputation, the body's natural tendency is to assume a position of comfort, which for the lower limb is hip and knee flexion. If not actively prevented, this can lead to Flexion contractures—a permanent shortening of muscles and tendons that makes fitting a prosthesis impossible and severely limits mobility. This complication is irreversible once established, making its prevention the highest nursing priority in the early postoperative period (beyond the first 24 hours).
Answer RationaleKey Point! Positioning the client prone for 30 minutes several times a day is the priority intervention. This position actively extends the hip joint, counteracting the tendency for hip flexion. It is a proactive, non-invasive measure that directly addresses the most serious long-term threat to the patient's functional recovery and future independence with a prosthetic limb.
Distractor AnalysisWatch out for confusion! Let's analyze why the other options, while relevant, are not the priority at this specific time (48 hours post-op):
① Administer analgesics for phantom limb pain: While pain management is a core nursing responsibility, phantom limb pain often develops later (days to weeks). At 48 hours, incisional pain is more likely. Furthermore, managing pain, though crucial for comfort, does not prevent the physical complication of a contracture.
② Elevate the residual limb on pillows: This is a classic distractor. Elevation is standard in the first 24 hours to control edema and promote venous return. However, beyond 24 hours, continuous elevation with pillows under the knee or residual limb is contraindicated because it promotes hip and knee flexion, directly leading to the contracture we are trying to prevent.
④ Apply ice packs to control swelling: Cryotherapy is typically used in the immediate postoperative period (first 12-24 hours) to reduce swelling and pain. By 48 hours, its benefit diminishes, and it is not a standard, priority intervention for promoting long-term healing or preventing major complications like contractures.
Related Concepts
Post-amputation care follows a phased approach: Immediate (0-24 hrs: hemorrhage control, edema management), Early (24-72 hrs: contracture prevention, wound assessment), and Rehabilitation (prosthetic fitting, gait training). Understanding this timeline is critical for prioritizing interventions on the NCLEX.

Side-by-Side Comparison!
Intervention
Purpose & Rationale
When to Use / When to Avoid
Prone Positioning
Prevents hip flexion contracture by stretching hip flexors.
USE: Start after first 24h, several times daily. AVOID: If contraindicated by other injuries or unstable vital signs.
Elevating Limb on Pillows
Reduces edema and promotes venous return.
USE:First 24 hours only.AVOID: After 24h, as it promotes flexion contracture.
Stump Wrapping (Elastic Bandage)
Shapes the residual limb, controls edema, prepares for prosthesis.
USE: Typically started once drains are removed and wound is stable. AVOID: If causing circulatory compromise (check for numbness, pallor).
Anatomy, Physiology & Pharmacology Points
Pathophysiology of Contracture: Prolonged positioning in flexion causes adaptive shortening of the Iliopsoas (primary hip flexor) and hamstring muscles. The joint capsule and ligaments also tighten, leading to a fixed deformity.
Phantom Limb Sensation vs. Pain: Sensation (feeling the limb is still there) is almost universal and not painful. Phantom pain is a neuropathic pain syndrome. First-line pharmacological management often includes medications like Gabapentin or Pregabalin.
Neurovascular Assessment (CMS): Post-amputation, frequent checks for Circulation (color, temperature, capillary refill), Movement (ability to move joints above amputation), and Sensation (in the remaining limb) are essential to detect complications like hemorrhage or infection.
Memory Tips
"Prone Prevents the Permanent Problem": A simple alliteration to remember the priority intervention (Prone positioning) for preventing the permanent problem (flexion contracture).
Timeline Rule for Elevation: "Pillows for the first day, then put them away." Elevation is only for the initial 24-hour period.
Contracture Consequence: Think "No contracture, yes prosthesis." A flexion contracture of the hip >15-20 degrees typically makes prosthetic fitting and walking impossible.
High-Frequency NCLEX Topics
NCLEX frequently tests the shift in priority from the immediate postoperative period to the early recovery phase. You must recognize that what is correct in the first 24 hours (elevation) becomes incorrect later. The exam also emphasizes nursing actions that promote long-term independence and prevent disability, making contracture prevention a classic high-yield topic.
Watch Out for Question Variations!
Shift in Time: The same scenario set "6 hours post-op" would make elevating the limb a correct priority. Always note the time!
Shift in Focus: A question might ask: "The nurse is teaching a client about residual limb care. Which client statement indicates a need for further teaching?" A correct wrong answer could be: "I will keep my leg elevated on two pillows when I sleep."
Integrated with Pain: A question could present a client with severe phantom pain and a visibly flexed hip, asking for the priority action. The answer would still involve addressing the contracture risk (e.g., implementing prone positioning) while also medicating for pain, as the physical complication is irreversible.
Nursing Clinical Practice GuideClinical Scenario: Mr. Johnson, a 68-year-old with a history of peripheral arterial disease (PAD) and diabetes, is on your medical-surgical unit post left BKA. It is post-op day 2. You notice he is consistently lying with a pillow under his knee and his hip slightly flexed. He mentions his hip is a little sore.
Nursing Intervention Strategy
Assessment: Perform a focused assessment. Check the incision site for signs of infection (redness, warmth, drainage). Perform a neurovascular check (CMS) on the residual limb. Assess the Range of Motion (ROM) of his hip and knee on the unaffected side for baseline, and gently assess for any limitation or pain with passive extension of the operative hip.
Nursing Diagnosis: Risk for impaired physical mobility related to musculoskeletal impairment and pain.
Planning & Implementation:
Priority Action: Educate Mr. Johnson on the importance of preventing hip contractures. Remove the pillow from under his knee. Explain the "why" simply: "Keeping your hip straight now will make it much easier to walk with an artificial leg later."
Implement Prone Positioning: Assist him into a prone position. Place a small pillow under his chest and ankles for comfort. Initially aim for 15-20 minutes, 2-3 times per day, gradually increasing to 30 minutes. Schedule this after pain medication for better tolerance.
Complementary Interventions: Teach and encourage isometric exercises (gluteal and quadriceps sets) to maintain muscle strength. Begin gentle, supervised ROM exercises for the hip into extension and abduction, as ordered.
Pain Management: Administer prescribed analgesics on a schedule (not just PRN) to keep him comfortable enough to participate in positioning and exercises.
Evaluation: Monitor tolerance to prone positioning. Reassess hip extension ROM daily. Evaluate his understanding by asking him to teach back the reason for avoiding pillows under the knee.
Patient Safety and Precautions
Contraindication for Prone Positioning: Do not place a patient prone if they have unstable vital signs, an unsecured airway, recent spinal surgery, or certain abdominal wounds. Always assess the patient's overall condition first.
Monitor for Pressure Injuries: The anterior surface of the body (chin, chest, iliac crests, knees) is now at risk during prone positioning. Use appropriate pressure-relieving padding and perform skin assessments.
Fall Risk: The patient's balance and mobility are altered. Ensure the bed is in the lowest position, call bell is within reach, and non-slip footwear is used when transferring.
Nursing Procedure & Medication FlowProcedure: Assisting with Prone Positioning Post-Amputation
Explain the procedure and its purpose to the patient.
Administer prescribed analgesic 30 minutes prior if needed for comfort.
Raise the bed to a comfortable working height. Lower the side rail on the working side.
With assistance if needed, help the patient roll onto their side, then onto their abdomen.
Position the head turned to one side on a small pillow for airway patency. Place a thin pillow under the chest/shoulders and under the ankles to keep toes off the bed.
Ensure the residual limb is in a neutral, extended position. The hip should not be rotated.
Set a timer for the prescribed duration (start with 15-20 min). Stay with the patient initially to assess tolerance.
After the time is up, assist the patient back to a supine or side-lying position.
Perform a skin assessment on pressure points. Document the procedure, duration, and patient tolerance.
Medication Note: For neuropathic phantom limb pain, medications like Gabapentin are often used. Nursing considerations include starting at a low dose, titrating up slowly, monitoring for side effects (dizziness, drowsiness, peripheral edema), and educating the patient that it may take weeks for full effect.
A Word from Your Senior Nurse
"Nursing is not just about carrying out physician orders — it's about being the frontline guardian for your patients! In the case of an amputation, you are the key to bridging the gap between a life-altering surgery and a future of regained independence. That pillow under the knee might seem like a small act of comfort, but you now understand it's a step toward a permanent disability. Your knowledge and proactive intervention—teaching, repositioning, encouraging—directly shape your patient's outcome. When studying for your boards, don't just memorize 'prone positioning' — connect it to Mr. Johnson's future ability to walk his daughter down the aisle. That mindset will not only earn you a great score on the NCLEX but will make you a truly confident, professional nurse!"
Flexion Contracture — A permanent shortening of muscles, tendons, or other soft tissues around a joint, resulting in the inability to fully extend the joint. After a BKA, a hip flexion contracture prevents prosthetic use.
Phantom Limb Sensation — The non-painful perception that the amputated limb is still present. It is a common neurological phenomenon and differs from phantom limb pain.
Neurovascular Assessment — A systematic check of Circulation (color, temperature, capillary refill, pulses), Movement (motor function), and Sensation (sensory function). Critical post-amputation to monitor for ischemia or nerve damage.
Range of Motion — The full movement potential of a joint. After amputation, maintaining ROM in the proximal joints (hip, knee) is essential for future mobility and ADLs.
Residual Limb — The remaining portion of the limb after amputation. Also called a stump. Care involves shaping, protecting, and preparing it for a prosthesis.
