A nurse is caring for a 70-year-old patient with diabetes and a stage 3 pressure injury on the sacrum. Which nursing intervention should be the highest priority?

An 82-year-old patient has been bedridden for 3 weeks following hip fracture surgery and has developed a stage 3 pressure injury on the sacrum measuring 4 cm × 3 cm with visible subcutaneous tissue and moderate exudate.

Implementing a turning schedule every 2 hours is the highest priority to relieve pressure and prevent further tissue damage in a stage 3 pressure injury. Other options (dressing application, wound cleansing with hydrogen peroxide, skin massage) are secondary or potentially harmful interventions.

Core Nursing Explanation Key Concept Analysis: This question assesses the priority nursing intervention for managing a Pressure injury (Pressure ulcer). The core principle is that the primary cause of pressure injury development and progression is unrelieved pressure. Therefore, the most fundamental and highest-priority intervention is always pressure redistribution. The patient is elderly, has diabetes (which impairs healing), and is bedridden post-surgery, placing them at very high risk. The wound is already at Stage 3, involving full-thickness skin loss with damage to subcutaneous tissue.

Answer Rationale: Key Point! The single most effective intervention to halt the progression of a pressure injury and allow for healing is to remove the source of the damage. A turning schedule every 2 hours is the standard of care for pressure relief in bedridden patients. This directly addresses the pathophysiological cause (ischemia from pressure) and is the foundation upon which all other wound care (dressings, cleansing) is built. Without pressure relief, other interventions are futile.

Distractor Analysis:
Watch out for confusion! Option ① (Apply a hydrocolloid dressing): While appropriate for some wounds, selecting a specific dressing is a secondary intervention. The priority is to first ensure pressure is relieved. Dressing selection comes after the cause is managed.
Watch out for confusion! Option ③ (Cleanse the wound with hydrogen peroxide): This is an incorrect and potentially harmful intervention. Hydrogen peroxide is cytotoxic and can damage healthy granulation tissue, delaying wound healing. Normal saline is the preferred solution for cleansing most pressure injuries.
Watch out for confusion! Option ④ (Massage the surrounding skin): This is a contraindicated action. Massaging over or around a pressure injury, especially over bony prominences, can cause shear and friction, further damaging delicate tissue and microvasculature.

Related Concepts: Nursing care for pressure injuries follows a systematic approach: Pressure Relief (P) → Moisture Management (M) → Nutrition (N) → Debridement/Treatment (T). This question tests the first and most critical "P". Remember, in the nursing process, addressing the etiology of the problem takes priority over treating its manifestations. Concept Summary The management of pressure injuries is rooted in the Braden Scale risk factors: Pressure, Shear/Friction, Moisture, Nutrition, Mobility, Sensory Perception. The priority interventions always target the primary causative factors.

Side-by-Side Comparison!
InterventionRationale & PriorityCommon Error
Turning Schedule (Q2h)Highest Priority. Addresses the root cause (pressure).Thinking a special mattress alone is sufficient without repositioning.
Appropriate DressingSecondary Priority. Manages moisture, protects, promotes healing.Choosing the wrong dressing type for the wound stage/exudate.
Proper Cleansing (Normal Saline)Essential but not the first priority. Removes debris without harming tissue.Using cytotoxic agents like hydrogen peroxide, povidone-iodine.
Skin Care (No Massage)Important for prevention. Keep clean and dry, use moisture barriers.Massaging reddened areas or bony prominences.

Anatomy, Physiology & Pharmacology Points
  • Pathophysiology: Sustained pressure > capillary closing pressure (approx. 32 mmHg) causes ischemia → tissue necrosis → ulceration. Shear forces (sliding) stretch and tear blood vessels.
  • Staging: Stage 3: Full-thickness skin loss with damage to/necrosis of subcutaneous tissue that may extend to but not through underlying fascia. Undermining and tunneling may be present.
  • Pharmacology Note: Patients with diabetes require meticulous glucose control (HbA1c < 7% is a common target) to optimize leukocyte function and healing.

Memory Tips
  • Priority Acronym: "Pressure Off First!" (P.O.F.).
  • Cleansing Rule: "Saline is Safe." Avoid harsh chemicals.
  • Massage Mnemonic: "Don't Rub a Reddened Bump" (DRRB).

High-Frequency NCLEX Topics Pressure injury prevention and staging is a Core NCLEX topic. Expect questions on: 1. Identifying the correct stage from a description or image. 2. Selecting the priority intervention (always pressure relief first). 3. Recognizing incorrect/harmful interventions (e.g., massage, donut rings, harsh antiseptics). 4. Calculating repositioning frequency (every 2 hours for bed, every 1 hour for chair).

Watch Out for Question Variations!
  • Variation 1: Post-operative patient: "A patient 2 days post-abdominal surgery is reluctant to turn due to pain. What is the nurse's best action?" (Answer: Administer prescribed analgesia before the scheduled turn to facilitate compliance with pressure relief).
  • Variation 2: Prevention focus: "For a high-risk patient on bed rest, which intervention is most effective for preventing pressure injuries?" (Answer: A structured repositioning/turning schedule).
  • Variation 3: Wound assessment: The question may ask you to stage the ulcer based on a description, then ask for the corresponding care.

임상 시나리오

Nursing Clinical Practice Guide Clinical Scenario: You are assigned to Mr. Johnson, an 82-year-old with a history of type 2 diabetes and a recent hip fracture repair. During your shift assessment, you discover a full-thickness wound on his sacrum with yellowish slough and moderate drainage. The wound team has staged it as a Stage 3 pressure injury.

Nursing Intervention Strategy: 1. Immediate Action (Priority): Document the wound findings thoroughly (using the TIME framework: Tissue, Infection/Inflammation, Moisture, Edge). Then, initiate/enforce a strict turning schedule. Log the turns. Use pillows and positioning devices to keep pressure off the sacrum (e.g., 30-degree lateral oblique positions). 2. Pressure Redistribution: Ensure the patient is on an appropriate pressure-redistributing support surface (e.g., low-air-loss or alternating pressure mattress). A standard hospital mattress is inadequate. 3. Wound Care: After ensuring pressure relief, cleanse the wound at each dressing change with warm normal saline using gentle irrigation. Apply a dressing appropriate for Stage 3 with moderate exudate (e.g., a calcium alginate or foam dressing). Collaborate with the wound care nurse. 4. Holistic Management: Work with dietary services to ensure high-protein, high-calorie nutrition with vitamin C and zinc supplementation to support healing. Meticulously manage blood glucose levels.

Patient Safety and Precautions:
  • NEVER use donut-shaped cushions or rubber rings. They increase pressure on surrounding tissue and impair circulation.
  • NEVER massage reddened or bony areas.
  • AVOID harsh cleansing agents (hydrogen peroxide, povidone-iodine, Dakin's solution) on granulating tissue.
  • When turning, use a draw sheet or lift sheet to minimize shear and friction. Do not drag the patient across the sheets.
  • Monitor for signs of infection: increased exudate, foul odor, fever, increased pain, or worsening erythema around the wound.

Nursing Procedure & Medication Flow Turning & Repositioning Procedure: 1. Explain the procedure to the patient. Pre-medicate for pain if needed. 2. Gather assistance if required. Lower the head of the bed. 3. Use a draw sheet to lift, not drag, the patient. 4. Reposition into a 30-degree side-lying position (alternating right, back, left). 5. Support with pillows behind the back, between knees/ankles, and under arms to maintain position and off-load the sacrum. 6. Document position and time. Set a timer for 2 hours.
Medication/Dressing Note: If a topical antimicrobial (e.g., silver sulfadiazine) is ordered, apply a thin layer to the wound bed per protocol after cleansing. Dressing changes are typically daily or as dictated by the amount of exudate.

A Word from Your Senior Nurse "In the real world, pressure injuries are often called a 'nurse-sensitive indicator' because our vigilance and consistent care directly prevent them. Finding a Stage 3 ulcer can feel discouraging, but your response is critical. Remember the mantra: Offload, Cleanse, Dress, Nourish, Repeat. Your first and most powerful tool is your hands and your watch—turning that patient every two hours, without fail, day and night. It's simple but non-negotiable. On the NCLEX, they are testing your clinical judgment to see if you know where to start. Always start by stopping the cause. That mindset will guide you to the right answer every time."
