A postpartum nurse is assessing a client who delivered vaginally 3 days ago and reports leg pain. Which assessment finding would be most indicative of thrombophlebitis?
1Bilateral leg edema with pitting
2Cramping pain that improves with walking
3Coolness and pallor of the affected extremity
4Unilateral leg pain with positive Homans' sign✓ 정답
해설
Thrombophlebitis typically presents with unilateral leg pain, warmth, redness, and a positive Homans' sign. Bilateral edema suggests other causes, cramping pain improves with walking in muscle cramps, and coolness/pallor indicate arterial issues.
Core Nursing ExplanationKey Concept Analysis: This question assesses the ability to identify the classic signs of Deep Vein Thrombosis (DVT) or thrombophlebitis in a postpartum patient. The postpartum period is a high-risk time for DVT due to hypercoagulability, venous stasis, and potential vessel injury during delivery (Virchow's triad). The core concept is differentiating venous (DVT) from arterial problems or other common postpartum complaints like muscle cramps or dependent edema.
Answer Rationale: Key Point! The correct answer is option 4. Thrombophlebitis (inflammation of a vein with clot formation) in the deep veins (DVT) classically presents with unilateral symptoms. A positive Homans' sign (pain in the calf upon forceful dorsiflexion of the foot) is a classic, though not definitive, assessment finding for DVT. In a postpartum patient reporting leg pain, this combination is a major red flag requiring immediate further evaluation (e.g., Doppler ultrasound) to prevent a potentially fatal Pulmonary Embolism (PE).
Distractor Analysis:
Watch out for confusion! Option 1: Bilateral leg edema with pitting is more suggestive of dependent edema (common postpartum due to fluid shifts), Preeclampsia, or systemic conditions like heart failure, not an acute unilateral DVT.
Option 2: Cramping pain that improves with walking is characteristic of muscular cramps or discomfort from inactivity, not thrombophlebitis. DVT pain is often a persistent ache or cramp that does not reliably improve with walking and may worsen.
Option 3: Coolness and pallor of the affected extremity are hallmarks of arterial insufficiency (e.g., acute arterial occlusion), where blood flow *into* the limb is blocked. DVT is a venous problem where blood return *from* the limb is impaired, typically leading to warmth, redness, and swelling.
Related Concepts: Postpartum nurses must vigilantly assess for signs of thromboembolism, a leading cause of maternal mortality. Other signs of DVT include localized warmth, erythema (redness), swelling, and palpable cord-like vein. Never massage a limb suspected of having a DVT. The nursing priority is to maintain the patient on bedrest, notify the provider, and anticipate orders for anticoagulant therapy (e.g., heparin, enoxaparin).
Concept Summary
Condition
Key Features
Pathophysiology
Deep Vein Thrombosis (DVT) / Thrombophlebitis
Unilateral leg pain/swelling, warmth, redness, positive Homans' sign, palpable cord
Clot formation in deep veins (often calf) due to Virchow's Triad: stasis, hypercoagulability, endothelial injury.
Postpartum Dependent Edema
Bilateral pitting edema, improves with elevation, no significant pain or warmth
Normal fluid mobilization and shifts after delivery; increased venous pressure in pelvis.
Muscle Cramp/Strain
Cramping pain, may improve with movement/stretching, no swelling or warmth
Present (may be difficult to palpate due to edema)
Diminished or absent
Pain
Aching, cramping, worse with dependency
Intermittent claudication or severe rest pain
Anatomy, Physiology & Pharmacology Points
Virchow's Triad: The three factors contributing to thrombosis: 1) Venous Stasis (e.g., bed rest postpartum), 2) Hypercoagulability (e.g., postpartum state, inherited disorders), 3) Endothelial Injury (e.g., trauma during delivery).
Homans' Sign: Calf pain on dorsiflexion. Note: This sign is neither highly sensitive nor specific. Its absence does not rule out DVT, and it should be performed cautiously to avoid dislodging a clot.
Anticoagulant Therapy: First-line treatment for DVT. Nurses must understand drugs like enoxaparin (Lovenox) - subcutaneous injection, monitoring for bleeding, and avoiding IM injections.
Postpartum Risk: Remember the "W" rule for postpartum DVT risk factors: Weight (obesity), Wound (C-section), Weeks on bedrest, With clotting disorder.
High-Frequency NCLEX Topics
This is a High Yield topic. The NCLEX frequently tests:
Identifying signs of postpartum complications (hemorrhage, infection, thromboembolism).
Differentiating assessment findings for venous vs. arterial disorders.
Knowing priority actions for a suspected DVT (e.g., bedrest, do not massage, notify provider).
Understanding patient safety with anticoagulant therapy.
Watch Out for Question Variations!
Symptom Identification → Priority Intervention: "The nurse assesses a positive Homans' sign in a postpartum client. Which action should the nurse take first?" (Answer: Notify the healthcare provider and keep the client on bedrest).
Medication Focus: "A client with postpartum DVT is prescribed enoxaparin. Which client statement indicates understanding of teaching?" (Answer: "I will use a soft toothbrush to prevent gum bleeding.").
Risk Factor Recognition: "Which postpartum client is at greatest risk for developing a DVT?" (Answer: A client with a history of thrombophilia who had an emergency cesarean section).
Nursing Clinical Practice GuideClinical Scenario: You are a nurse on the mother-baby unit. Mrs. Johnson, a 28-year-old G1P1 who had a vaginal delivery 3 days ago, calls you to her room. She states, "My left calf really hurts, and it feels tight when I walk." You immediately think of DVT.
Nursing Intervention Strategy:
Assessment:
Inspect & Palpate: Compare both legs. Look for unilateral swelling, redness, warmth. Gently palpate the calf for tenderness and a cord-like vein. Key Point! Measure calf circumference at a marked point (e.g., 10 cm below tibial tuberosity) for objective comparison.
Vital Signs: Check for tachycardia, tachypnea, or decreased oxygen saturation—potential signs of PE.
Homans' Sign: Perform cautiously. With the client's knee slightly flexed, gently dorsiflex the foot. Ask, "Does this cause pain in your calf?" A positive sign increases suspicion but is not diagnostic.
Immediate Actions (Priority!):
Instruct the client to stay in bed with the affected leg elevated (unless contraindicated). Absolutely do not massage the leg!
Notify the healthcare provider immediately with your assessment findings.
Diagnostic: Doppler ultrasound of the lower extremity.
Pharmacological: Initiation of anticoagulant (e.g., subcutaneous enoxaparin or IV heparin drip).
Monitoring: Frequent vital signs, assessment for bleeding (gums, urine, injection sites), and signs of PE (sudden chest pain, dyspnea).
Education: Teach signs of bleeding and PE, importance of compliance with anticoagulants, and avoidance of NSAIDs (e.g., ibuprofen).
Patient Safety and Precautions:
Contraindication: Never apply heat or vigorously massage a limb suspected of DVT due to risk of embolization.
Medication Caution: When administering anticoagulants, use appropriate needle length for subcutaneous injection (e.g., insulin syringe or pre-filled syringe), inject into abdomen (at least 2 inches from umbilicus), and do not aspirate or rub the site.
Key Monitoring: For patients on heparin, monitor aPTT (activated Partial Thromboplastin Time); for warfarin, monitor INR (International Normalized Ratio). Know the therapeutic ranges.
Clean site with alcohol. Pinch a skin fold. Hold syringe like a pencil.
Insert needle at a 90-degree angle into the skin fold. Do not aspirate.
Inject medication slowly. Wait 10 seconds before withdrawing needle.
Release skin fold. Do not massage the area. Apply gentle pressure if needed.

A Word from Your Senior Nurse
"Postpartum nursing is joyful but requires a vigilant eye. That 'simple leg cramp' a new mom mentions could be a life-threatening clot. Your assessment skills are her first line of defense. Always think 'Could this be a DVT?' when you hear 'leg pain.' By connecting the pathophysiology (Virchow's triad in the postpartum period) to your clinical assessment (unilateral signs, Homans'), you move from task-oriented care to true patient advocacy and safety. This critical thinking is exactly what the NCLEX tests and what makes an excellent nurse."
