A nurse is assessing a surgical wound on postoperative day 5 and observes granulation tissue formation with wound edges approximating well. Which finding would indicate that the wound is progressing normally through the proliferative phase of healing?

해설
Pink, granular tissue with new capillary formation is characteristic of the proliferative phase, indicating normal healing. Other options describe inflammatory phase, infection, or maturation phase.

Core Nursing Explanation Key Concept Analysis: This question tests your understanding of the normal progression of wound healing, specifically the characteristics of the Proliferative phase. Wound healing occurs in four overlapping phases: Hemostasis, Inflammatory, Proliferative, and Maturation/Remodeling. The proliferative phase, which typically begins around day 3-5 post-injury, is marked by the growth of new tissue to fill the wound defect.

Answer Rationale: Key Point! The hallmark of the proliferative phase is the development of Granulation tissue. This tissue is pink or red, moist, and has a granular or "bumpy" appearance because it is rich in newly formed capillaries (angiogenesis) and fibroblasts that are producing collagen. The description "pink, granular tissue filling the wound bed with new capillary formation" is the textbook definition of healthy granulation tissue, directly indicating normal progression through the proliferative phase.

Distractor Analysis:
Watch out for confusion! Option ① describes Hemostasis, the immediate first phase of healing involving clot formation, not the proliferative phase seen on day 5.
Option ② describes classic signs of Infection (redness, swelling, warmth, purulent drainage) or an exaggerated inflammatory response, which is abnormal and indicates impaired healing.
Option ④ describes the final Maturation or Remodeling phase, where collagen is reorganized and strengthened, and re-epithelialization is complete. This phase lasts for months to years, not days.

Related Concepts: Understanding wound healing phases is crucial for accurate assessment. A nurse must differentiate between normal healing signs (like healthy granulation) and signs of complications (like infection, dehiscence, or poor granulation). This knowledge directly informs wound care interventions, such as selecting appropriate dressings to maintain a moist wound environment conducive to proliferation.

Anatomy, Physiology & Pharmacology Points
  • Granulation Tissue Components: Composed of Fibroblasts (produce collagen Type III), New Capillaries (Angiogenesis), and inflammatory cells in a matrix. It is the foundation for new skin growth.
  • Collagen Types: Type III collagen is laid down in the proliferative phase. It is later replaced by stronger Type I collagen during the maturation phase.
  • Factors Affecting Proliferation: Adequate oxygenation (for angiogenesis), nutrition (protein, Vitamin C, zinc), moisture, and absence of infection are critical.

Memory Tips
  • Pink & Bumpy = Proliferating: Associate the pink, bumpy look of granulation tissue with the "Proliferative" phase.
  • Phase Timeline Mnemonic: "Help! It's Painful, Make it better!" (Hemostasis, Inflammatory, Proliferative, Maturation).
  • Granulation vs. Infection: Healthy granulation is moist and pink/red. Infection often presents with excess moisture (purulent drainage), increased redness, and heat.

High-Frequency NCLEX Topics Wound healing is a Core topic. The NCLEX-RN frequently tests:
  1. Identifying the phase of healing based on assessment findings.
  2. Differentiating signs of normal healing from signs of infection or complication (e.g., dehiscence, evisceration).
  3. Selecting appropriate nursing interventions or dressings for each phase (e.g., dry vs. moist environment).
  4. Understanding patient factors that impair healing (diabetes, malnutrition, steroids).

Watch Out for Question Variations! The same concept can be tested in multiple ways:
  • From Symptom to Phase: "A nurse observes beefy red, moist tissue in a wound. The nurse documents this as which phase of healing?" (Answer: Proliferative).
  • From Phase to Intervention: "For a patient in the proliferative phase of wound healing, which dressing is most appropriate?" (Answer: A dressing that maintains a moist environment, like a hydrocolloid or foam).
  • Priority Recognition: "On postoperative day 5, a nurse assesses a wound and finds it swollen, warm, with yellow drainage. What is the nurse's priority action?" (Answer: Notify the provider of possible infection, may obtain a wound culture).

임상 시나리오

Nursing Clinical Practice Guide Clinical Scenario: You are caring for Mr. Johnson, a 68-year-old with a history of Type 2 Diabetes Mellitus (DM), who underwent an appendectomy 5 days ago. During your morning assessment, you remove the dressing from his midline abdominal incision to inspect it.

Nursing Intervention Strategy:
  1. Assessment: Perform hand hygiene and don gloves. Observe the wound for location, size, and characteristics of the wound bed. You note the edges are well-approximated (closed together) with staples intact. The wound bed is filled with pink, moist, granular tissue—no exposed bone or tendon. There is a small amount of serosanguinous drainage on the old dressing. The surrounding skin is intact, without redness, warmth, or induration. This is a normal finding for the proliferative phase.
  2. Nursing Diagnosis & Planning: Based on your assessment, a potential nursing diagnosis is "Risk for Impaired Skin Integrity" related to surgical incision. The plan is to protect the granulation tissue, prevent infection, and promote continued healing.
  3. Implementation:
    • Wound Care: Cleanse the wound per protocol (often with normal saline). Apply a moisture-retentive dressing like a hydrocolloid or thin foam. This protects the fragile new capillaries and creates an optimal environment for healing.
    • Patient Education: Teach Mr. Johnson to report any increase in pain, redness, swelling, or foul-smelling drainage. Reinforce the importance of good nutrition (high protein, Vitamin C) and blood glucose control for healing.
    • Collaboration: Document your findings accurately: "Incision midline abdomen, staples intact, edges well-approximated. Wound bed filled with pink granulation tissue, minimal serosanguinous drainage on old dressing. No signs of infection."
Patient Safety and Precautions:
  • Aseptic Technique: Always use sterile or clean technique (as per facility policy and wound type) during dressing changes to prevent introducing pathogens.
  • Diabetic Patients: Be extra vigilant. Hyperglycemia impairs neutrophil function and angiogenesis, delaying the proliferative phase and increasing infection risk. Monitor blood glucose closely.
  • Never Use Dry Gauze on a granulating wound. It can stick to the new tissue, causing trauma and pain upon removal (this is why we use non-adherent or moist dressings).

Nursing Procedure & Medication Flow Wound Dressing Change (Clean Technique for Closed Surgical Incision): 1. Gather supplies: Clean gloves, sterile saline, gauze, appropriate primary dressing (e.g., hydrocolloid), tape, biohazard bag. 2. Explain procedure to patient. Provide privacy. 3. Perform hand hygiene. Don clean gloves. 4. Remove old dressing gently. Discard in biohazard bag. 5. Inspect wound (as described above). 6. Cleanse wound from center outward using sterile saline and gauze, using a new piece for each stroke. 7. Allow area to air dry or pat dry with sterile gauze. 8. Apply new dressing. Secure. 9. Remove gloves, perform hand hygiene. 10. Document.

A Word from Your Senior Nurse: "Assessing a wound is like reading a story. The color, moisture, and tissue type tell you exactly what chapter of healing the patient is in. Seeing that beautiful pink granulation tissue is one of the most satisfying signs that your care is working. But remember, if the story changes—if pink turns to red and swollen, or moist turns to purulent—you are the first to know. Your sharp assessment skills are the early warning system that prevents a simple delay from becoming a major complication. On the NCLEX and at the bedside, think phases, think tissue types, and always connect your findings to the 'why' of physiology."
