A nurse is assessing a 78-year-old patient who has been bedridden for 5 days following hip fracture surgery. Which assessment finding would be the MOST concerning for pressure injury development?
1Skin temperature that is slightly cooler than surrounding tissue over the sacral area
2Non-blanchable erythema over the coccyx that persists after position change✓ 정답
3Mild skin dryness and flaking noted on bilateral lower extremities
4Temporary redness over bony prominences that disappears within 30 minutes of repositioning
해설
Non-blanchable erythema over the coccyx that persists after position change indicates Stage 1 pressure injury, requiring immediate intervention. Other findings like cool skin, dryness, or temporary redness are less concerning as they represent normal variations or early reversible changes.
Core Nursing ExplanationKey Concept Analysis: This question tests the nurse's ability to identify the earliest clinical sign of a pressure injury (also known as a pressure ulcer or bedsore) in a high-risk patient. The core pathophysiology involves unrelieved pressure causing localized tissue ischemia and damage. A 78-year-old, bedridden, post-surgical patient is at extremely high risk due to immobility, potential poor nutrition, and age-related skin changes.
Answer Rationale: Key Point! The correct answer is Non-blanchable erythema over the coccyx that persists after position change. This is the hallmark sign of a Stage 1 pressure injury according to the NPUAP (National Pressure Ulcer Advisory Panel) classification. "Non-blanchable" means the redness does not fade when you press on it with a finger, indicating that capillary blood flow is not returning, a sign of underlying tissue damage. The coccyx (tailbone) is a high-risk bony prominence. This finding requires immediate intervention (e.g., pressure redistribution, frequent repositioning, skin protection) to prevent progression to more severe stages.
Distractor Analysis:
Watch out for confusion!
Option 1 (Skin temperature that is slightly cooler): Cool skin can indicate poor circulation, which is a risk factor, but it is not a definitive sign of active pressure injury development. It is a less specific finding.
Option 3 (Mild skin dryness and flaking): This indicates xerosis (dry skin), which can make skin more fragile and susceptible to breakdown, but it is not an indicator of actual tissue damage or ischemia. It requires moisturizing but is not the *most* concerning finding.
Option 4 (Temporary redness that disappears): This describes reactive hyperemia, a normal physiological response where blood rushes back to an area after pressure is relieved. It is a protective mechanism and blanches (fades) with pressure. This is a positive sign that tissues are still viable and is not classified as a pressure injury.
Related Concepts: Understanding the pressure injury staging system (Stages 1-4, Unstageable, Deep Tissue Pressure Injury) is critical. The nursing process mandates proactive skin assessments using tools like the Braden Scale to predict risk. Core preventive interventions include the "Q2 hour turn" schedule, use of pressure-redistributing support surfaces, managing moisture, and optimizing nutrition.
Concept Summary
Concept
Description
Clinical Significance
Stage 1 Pressure Injury
Intact skin with non-blanchable redness.
Earliest sign; reversible with prompt intervention.
Reactive Hyperemia
Blanchable redness that fades after pressure relief.
Normal, healthy response; not tissue damage.
Non-blanchable Erythema
Redness that does NOT fade when pressed.
Indicates capillary occlusion and tissue ischemia.
Pharmacology: No direct drugs treat pressure injuries. Prevention is key. Nutritional supplements (Protein, Vitamin C, Zinc) support healing. Topical barriers protect skin from moisture.
Memory Tips
Blanch vs. Non-Blanch: Think of your finger as a "tissue vitality test." If the color goes away (blanches), tissue is alive. If it stays red, it's a "red flag" for damage.
Stage 1 Mnemonic: "Red and Remains" (non-blanchable).
High-Frequency NCLEX Topics
Pressure injury prevention and staging is a Core and frequently tested topic. NCLEX loves to test:
Identifying Stage 1 vs. reactive hyperemia.
Selecting the priority nursing intervention for a patient at risk.
Understanding the rationale behind turning schedules and support surfaces.
Watch Out for Question Variations!
Symptom ID → Priority Action: "The nurse identifies non-blanchable erythema on a patient's sacrum. What is the nurse's priority action?" (Answer: Reposition the patient to relieve pressure on the area).
Risk Factor Analysis: "Which patient is at greatest risk for pressure injury development?" (Look for immobility, incontinence, malnutrition, altered consciousness).
Teaching Focus: "Which statement by a family caregiver indicates understanding of pressure injury prevention?" (e.g., "I will help her change position every 2 hours.").
Nursing Clinical Practice GuideClinical Scenario: You are caring for Mr. Johnson, a 78-year-old man who is 5 days post-op from a hip pinning. He is on bedrest, has occasional urinary incontinence, and his appetite has been poor. During your morning assessment, you note a persistent red area over his coccyx that does not fade when you press it.
Nursing Intervention Strategy:
Assessment: Perform a comprehensive skin assessment. Document the size, color, temperature, and description (non-blanchable) of the area. Use the Braden Scale to score his risk (likely very low score). Assess pain, nutrition, and continence.
Nursing Diagnosis: Risk for impaired skin integrity related to immobility and pressure; or Impaired skin integrity if Stage 1 is confirmed.
Planning & Implementation:
Immediate Action: Reposition him off the sacral area immediately (e.g., 30-degree lateral tilt). Never drag him across sheets (friction!).
Pressure Redistribution: Implement a strict turning schedule (at least every 2 hours). Use a pressure-redistributing mattress. Protect heels with offloading devices.
Skin Care: Gently cleanse skin after incontinence. Apply a moisture-barrier ointment. Keep skin dry but not overly dry.
Nutrition: Collaborate with the dietitian to increase protein and calorie intake. Encourage oral supplements.
Documentation & Communication: Accurately chart the finding as a "Stage 1 pressure injury" or "non-blanchable erythema." Notify the primary care provider/R.N. and the wound care nurse if available.
Patient Safety and Precautions:
Do NOT massage reddened areas. Massaging can cause further tissue damage from shear.
Do NOT use donut-shaped cushions. They can impair blood flow to the area in the center, worsening ischemia.
Monitor closely for progression to Stage 2 (partial-thickness skin loss, blister).
Inspect all bony prominences, especially the sacrum, heels, and hips.
Perform the blanch test: Press a finger firmly on the red area for 3 seconds. Observe if redness fades.
If non-blanchable, document and initiate turning protocol.
Use a lift sheet or trapeze to move the patient without friction/shear.
Position with pillows to maintain 30-degree side-lying position.
A Word from Your Senior Nurse
"Spotting that first sign of a pressure injury—that non-blanchable red spot—is one of the most crucial assessments you'll make for an immobile patient. It's your early warning system. In clinical practice, it's not just about the 'Q2 turn.' It's about looking at the whole picture: Is the patient eating enough protein? Are they incontinent? Are they sliding down in bed? Your vigilant assessment and holistic intervention can prevent weeks of painful healing for the patient. On the NCLEX, they test this because it's fundamental to safe, quality nursing care. Remember: 'See red, think ahead!'"
Pressure Injury (Pressure Ulcer) — Localized damage to the skin and/or underlying soft tissue, usually over a bony prominence, due to intense and/or prolonged pressure or pressure in combination with shear.
Non-blanchable Erythema — Redness of intact skin that does not turn white (blanch) when finger pressure is applied; the hallmark sign of a Stage 1 pressure injury.
Reactive Hyperemia — A transient reddening of the skin that occurs when pressure is relieved; it blanches with pressure and indicates normal blood flow return, not tissue damage.
Braden Scale — A validated tool used to predict a patient's risk for developing pressure injuries by assessing six categories: sensory perception, moisture, activity, mobility, nutrition, and friction/shear.
Shear — A mechanical force that occurs when tissue layers slide over one another, stretching and tearing capillaries and contributing to pressure injury development (e.g., when a patient slides down in bed).
