A nurse is caring for a client with a stage 3 pressure ulcer on the sacrum that is in the proliferative phase of wound healing. Which nursing intervention is most appropriate to promote optimal healing during this phase?

해설
Maintaining a moist wound environment supports granulation tissue formation and epithelial migration during the proliferative phase. Other options (dry dressing, aggressive irrigation, keeping dry) can damage new tissue or impede healing.

심화 해설

Core Nursing Explanation Key Concept Analysis: This question tests the application of Evidence-Based Wound Care principles, specifically for managing a Stage 3 pressure ulcer during the Proliferative Phase of healing. The proliferative phase is characterized by the growth of Granulation tissue (new connective tissue and capillaries) and Epithelialization (migration of epithelial cells across the wound bed). The core nursing goal during this phase is to protect this fragile new tissue and create an environment that supports cellular growth and movement.

Answer Rationale: Key Point! The principle of Moist Wound Healing is fundamental to modern wound management. A moist environment facilitates the migration of epithelial cells, promotes angiogenesis (formation of new blood vessels), and supports the activity of growth factors and enzymes essential for tissue repair. Keeping the wound bed moist prevents the formation of a dry scab, which acts as a physical barrier to cell migration and delays healing. Therefore, the most appropriate intervention is to Maintain a moist wound environment and protect the granulation tissue.

Distractor Analysis:
Watch out for confusion! Option ①, "Apply a dry sterile dressing to absorb excess drainage," is incorrect because a dry dressing can adhere to the wound bed. When removed, it can cause Mechanical Debridement, tearing away the delicate new granulation tissue and setting back the healing process. Dry dressings are generally not recommended for wounds in the proliferative phase.
Option ②, "Perform aggressive wound irrigation with normal saline," is incorrect. While gentle irrigation with normal saline is a standard part of wound cleansing to remove debris and reduce bacterial load, aggressive irrigation implies using high pressure. This high pressure can be traumatic to the fragile new capillaries and granulation tissue, damaging the very structures the body is trying to build.
Option ③, "Keep the wound bed completely dry to prevent bacterial growth," is a common misconception. A dry environment does not necessarily prevent bacterial growth and, more importantly, it severely impedes the cellular processes of healing. Modern wound care science has conclusively shown that a Moist, clean environment optimizes healing while managing bacterial burden through appropriate dressings and topical agents, not by desiccation.

Related Concepts: The choice of a specific dressing (e.g., hydrocolloid, foam, alginate, hydrogel) depends on the amount of exudate, wound depth, and presence of infection. The goal is to manage moisture balance—not too wet (to avoid maceration of surrounding skin) and not too dry. Protecting granulation tissue also involves minimizing pressure and shear forces on the wound site, which is why repositioning and pressure redistribution surfaces remain critical concurrent interventions.

ConceptDescriptionNursing Implication
Proliferative PhasePhase of wound healing involving granulation tissue formation, angiogenesis, and epithelialization.Protect new tissue. Maintain a moist, clean environment to support cell migration and growth.
Granulation TissueNew connective tissue and microscopic blood vessels that fill a wound. Appears red, moist, and bumpy.Handle gently. Avoid dressings that adhere. Signs of healthy healing.
Moist Wound HealingEvidence-based principle that a moist environment accelerates epithelialization and reduces pain.Select dressings that maintain optimal moisture (e.g., hydrocolloids, foams, hydrogels).
Stage 3 Pressure UlcerFull-thickness tissue loss with damage or necrosis of subcutaneous tissue that may extend to, but not through, underlying fascia.Requires moist wound healing principles, possible debridement, offloading pressure, and nutritional support.

Anatomy, Physiology & Pharmacology Points
  • Physiology: Epithelial cells require a moist, electrolyte-rich environment to migrate across a wound surface. They cannot move under a dry scab; they must burrow underneath it, which takes longer.
  • Pathophysiology: A Stage 3 ulcer involves the Dermis and Subcutaneous tissue. Healing requires filling this depth with granulation tissue before epithelialization can cover it.
  • Pharmacology (Related): Topical growth factors (e.g., becaplermin gel) may be used in chronic wounds to stimulate the proliferative phase. Antimicrobial dressings (e.g., silver, iodine) are used to control critical colonization or infection, which can stall the proliferative phase.
Memory Tips
  • Mnemonic for Phases: Inflame, Proliferate, Mature (IPM). For Proliferative, think "Protect the Pink, Perfectly moist" (pink granulation tissue).
  • Clinical Pearl: "If it's dry, we want to wet it; if it's wet, we want to dry it." This oversimplified saying highlights moisture balance. A dry wound needs hydration (hydrogel); a heavily exuding wound needs absorption (alginate, foam).
High-Frequency NCLEX Topics The NCLEX frequently tests the principle of moist wound healing and the characteristics of different wound healing phases. You may be asked to:
  1. Select the appropriate dressing type based on wound description (exudate amount, tissue type).
  2. Identify the phase of healing based on clinical findings (e.g., "red, bumpy tissue" = proliferative).
  3. Prioritize nursing actions for a patient with a pressure ulcer (e.g., offloading pressure is always a priority alongside local wound care).
Watch Out for Question Variations!
  • Variation 1 (Priority): "The nurse notes healthy, red granulation tissue in a wound. Which action should the nurse take first?" Correct answer would focus on protecting that tissue (e.g., apply a non-adherent dressing) rather than cleansing it aggressively.
  • Variation 2 (Dressing Selection): Instead of a general intervention, you might be given a list of specific dressings (Transparent film, Hydrocolloid, Alginate, Gauze) and asked to choose the best one for a moist, granulating wound with minimal exudate (Answer: Hydrocolloid).
  • Variation 3 (Patient Education): "Which statement by a family member caring for a patient with a healing wound indicates understanding?" Correct response would be something like, "I will make sure the dressing keeps the wound moist."

임상 시나리오

Nursing Clinical Practice Guide Clinical Scenario: You are assigned to Mr. Johnson, a 78-year-old immobile patient with a history of a CVA (Cerebrovascular Accident). During your shift assessment, you find a stage 3 pressure ulcer on his sacrum. The wound bed is 80% covered with beefy red, moist granulation tissue, with minimal yellow slough at the edges and scant serous drainage.

Nursing Intervention Strategy:
  1. Assessment: Document wound characteristics using the TIME framework: Tissue (non-viable vs. viable), Infection/Inflammation, Moisture imbalance, Edge of wound. Measure size, note color of tissue (red/granulating, yellow/slough, black/eschar), amount and type of exudate, and condition of periwound skin.
  2. Cleansing: Use gentle irrigation with a syringe and angiocath (not a needle) with warmed normal saline. The goal is to cleanse without damaging tissue. Avoid cytotoxic agents like hydrogen peroxide or povidone-iodine on granulating tissue.
  3. Dressing Selection & Application: Based on the assessment (minimal exudate, mostly granulation tissue), a Hydrocolloid dressing or a Foam dressing would be appropriate to maintain a moist environment. Gently place the dressing without packing it tightly. Secure it well to prevent shearing but avoid tape on fragile skin (use a skin barrier or tubular netting).
  4. Concurrent Care: Implement a strict Turning and Repositioning schedule (every 2 hours) using a turn clock. Use a pressure-redistributing mattress. Collaborate with the dietitian to ensure adequate protein, calories, vitamin C, and zinc intake to support healing.
  5. Evaluation: Reassess the wound with each dressing change. Positive signs include increasing amount of granulation tissue, decreasing wound size, and clean edges. Report signs of infection (increased pain, erythema, warmth, purulent drainage, foul odor) or failure to progress.
Patient Safety and Precautions:
  • Contraindication: Do not use dry gauze directly on a granulating wound bed, as it will cause trauma on removal.
  • Medication Caution: If a topical enzymatic debriding agent is ordered for the remaining slough, apply it only to the non-viable tissue, protecting the surrounding granulation tissue and skin.
  • Key Monitoring: Monitor for periwound Maceration (white, soggy skin) caused by excessive moisture, which indicates the need for a more absorbent dressing.
Nursing Procedure & Medication Flow Procedure: Applying a Moist Wound Dressing
  1. Perform hand hygiene and don clean gloves.
  2. Remove old dressing gently. If it adheres, moisten with saline to loosen.
  3. Discard dressing and gloves in biohazard waste. Perform hand hygiene again.
  4. Don new sterile gloves.
  5. Cleanse wound with sterile normal saline using gentle irrigation or patting.
  6. Pat periwound skin dry.
  7. Apply selected moisture-retentive dressing according to manufacturer's instructions.
  8. Secure dressing. Label with date, time, and your initials.
  9. Document wound assessment and intervention.
A Word from Your Senior Nurse "Remember, wound care is both a science and an art. The science tells us to keep it moist. The art is in your careful assessment and gentle touch. When you see that beautiful pink granulation tissue growing, you're seeing the direct result of your skilled care. On the NCLEX, they want to know you understand the 'why' behind the moist wound principle. In clinical practice, your vigilant monitoring for subtle changes—a slight increase in drainage, a new area of redness—is what makes you your patient's advocate and prevents a simple wound from becoming a life-threatening complication. Think like a detective and a healer combined!"
