A nurse is caring for a 35-year-old construction worker with a compound fracture of the right tibia who underwent open reduction and internal fixation (ORIF) 48 hours ago. The client reports severe pain (8/10) despite receiving prescribed analgesics, and the nurse observes swelling, pallor, decreased sensation, weak pedal pulses, and capillary refill of 4 seconds in the affected extremity. What is the nurse's priority action?
1Administer an additional dose of prescribed pain medication
2Notify the physician immediately about possible compartment syndrome✓ 정답
3Elevate the affected extremity above heart level
4Apply ice packs to reduce swelling and inflammation
해설
The client shows signs of compartment syndrome (severe pain, swelling, pallor, decreased sensation), a surgical emergency requiring immediate physician notification to prevent permanent tissue damage. Other interventions like pain meds, elevation, or ice are inappropriate as initial actions.
Core Nursing ExplanationKey Concept Analysis: This question assesses the nurse's ability to recognize and prioritize care for Compartment Syndrome, a limb-threatening surgical emergency. It occurs when increased pressure within a closed fascial compartment compromises blood flow to the muscles and nerves. The classic presentation is the "6 Ps": Pain (out of proportion, unrelieved by opioids), Pallor, Paresthesia (or decreased sensation), Paralysis (or weakness), Pulselessness (or diminished pulses), and Poikilothermia (coolness). The patient's history of a tibia fracture and recent ORIF is a classic risk factor.
Answer Rationale: Key Point! The nurse's priority action is to notify the physician immediately. Compartment syndrome is a time-sensitive condition where irreversible muscle and nerve ischemia can occur within 4-6 hours. The primary treatment is an emergency surgical fasciotomy to relieve the pressure. The nurse must act as the patient's advocate to escalate care without delay. The described symptoms (severe pain unrelieved by meds, pallor, decreased sensation, weak pulses, capillary refill > Normal Value 2 seconds) are hallmark signs.
Distractor Analysis:
① Watch out for confusion! Administering more pain medication masks the cardinal symptom (pain out of proportion) and delays critical intervention. Pain in compartment syndrome is caused by ischemia, not just inflammation.
③ Elevating the extremity above heart level is contraindicated in suspected compartment syndrome. Elevation can reduce arterial perfusion pressure, worsening ischemia.
④ Applying ice can cause vasoconstriction, further reducing blood flow to the already compromised compartment.
Related Concepts: This scenario integrates knowledge of post-operative orthopedic care, neurovascular assessment, and emergency response. Understanding the pathophysiology of ischemia and the "6 Ps" is crucial for rapid identification.Nursing Clinical Practice GuideClinical Scenario: You are the day-shift nurse for Mr. Johnson, a construction worker who had surgery for a broken leg two days ago. He's restless, rates his pain an 8/10 despite his scheduled oxycodone, and says his leg feels "tight and numb." On assessment, his right foot is pale and cool to touch, the dorsalis pedis pulse is faint, and capillary refill is sluggish.
Nursing Intervention Strategy:
1. Immediate Assessment & Communication: Do not leave the patient. Use the call bell to have another nurse immediately page the orthopedic surgeon or trauma team. State clearly: "Suspected compartment syndrome in room 402, post-op day 2 ORIF right tibia. Patient has unrelenting pain, pallor, paresthesia, and diminished pulses."
2. Concurrent Actions: While awaiting the physician, do not elevate the limb. Keep it level with the heart. Loosen any constrictive dressings or casts, but do not remove them (this is typically a physician's order). Document a thorough neurovascular assessment with exact times.
3. Prepare for Intervention: Anticipate orders for stat compartment pressure measurement or direct transfer to the OR for fasciotomy. Ensure IV access is patent for possible fluid resuscitation or medications.
Patient Safety and Precautions: The biggest mistake is delaying notification. Never assume pain is "normal" post-op pain after an orthopedic procedure, especially when accompanied by neurovascular changes. Continuous monitoring of the "6 Ps" is essential.
Circulation: Check pulse (dorsalis pedis, posterior tibial), capillary refill (Normal Value ≤ 2 seconds), color, temperature, and edema.
Motor: Ask patient to wiggle toes ("dorsiflex and plantarflex"). Note any weakness or inability.
Sensation: Check light touch sensation on the top and bottom of the foot. Ask about numbness or tingling (paresthesia).
Pain Management Note: Pain from compartment syndrome is often described as deep, burning, and unrelenting. It typically does not improve with opioid analgesics, which is a critical red flag.
A Word from Your Senior Nurse
"Compartment syndrome is a true 'time is tissue' emergency. As a nurse, your sharp assessment skills and confidence to escalate care immediately can save a patient's limb. In orthopedics, never become complacent about pain. Always ask yourself: 'Is this pain expected, or is it telling me something is dangerously wrong?' Trust your gut when the assessment findings don't add up. On the NCLEX, they love to test your ability to prioritize in emergencies—knowing when to call for help is often the highest-priority answer."
Compartment Syndrome — A condition where increased pressure within a closed fascial compartment compromises blood flow, leading to muscle and nerve ischemia. A surgical emergency.
Neurovascular Assessment (CMS Checks) — Systematic assessment of Circulation (pulses, color, temperature, capillary refill), Motor function, and Sensation in an extremity.
The 6 Ps — Mnemonic for signs of acute compartment syndrome: Pain (out of proportion), Pallor, Paresthesia, Paralysis, Pulselessness, Poikilothermia (coolness).
Fasciotomy — Emergency surgical procedure to cut the fascia and relieve pressure within a muscle compartment to treat compartment syndrome.
Open Reduction and Internal Fixation — A surgical procedure to realign (reduce) and stabilize a fractured bone using implants like plates, screws, or rods.
