Core Nursing Explanation
This question assesses the priority nursing intervention for managing a
Pressure ulcer (also known as a pressure injury). The core principle is the
Nursing Process and the concept of
Key Point! addressing the root cause of a problem first. The patient is elderly with limited mobility and has a Stage 2 pressure ulcer, indicating partial-thickness skin loss.
Key Concept Analysis: The primary etiology of a pressure ulcer is
unrelieved pressure over a bony prominence, leading to ischemia and tissue necrosis. All other interventions (wound care, nutrition) are supportive but are ineffective if the source of pressure is not removed. The
Braden Scale is a key tool for predicting pressure ulcer risk, with mobility and activity being major components.
Answer Rationale:
Key Point! The priority is to stop the ongoing tissue damage.
Implementing a turning schedule every 2 hours directly addresses the causative factor—pressure. This is a foundational, non-negotiable intervention in pressure ulcer prevention and management. It aligns with the principle of
pressure redistribution.
Distractor Analysis:
-
Watch out for confusion! While applying a
Hydrocolloid dressing (Option 2) is a correct and important intervention for a Stage 2 ulcer (providing a moist wound environment and protecting from shear/friction), it is a
secondary intervention. Dressing the wound is futile if pressure on the area continues.
- Increasing
Protein intake (Option 3) is crucial for wound healing, as protein is needed for tissue repair. However, optimizing nutrition is a supportive, long-term strategy and does not immediately stop the mechanical damage.
-
Watch out for confusion! Massaging reddened areas (Option 4) is
contraindicated. Massage can cause further damage to the delicate capillaries in the compromised tissue (blanching vs. non-blanching erythema). This is an outdated practice that should be avoided.
Related Concepts: This question integrates fundamentals of
Gerontological nursing,
Wound care, and
patient safety. Remember the hierarchy of care: First, remove the cause (pressure); second, provide local wound care; third, support systemic healing (nutrition, hydration).
Concept Summary
-
Etiology: Pressure + Shear/Friction + Moisture → Ischemia → Tissue Necrosis.
-
Staging (NPUAP Classification): Stage 1: Non-blanchable erythema; Stage 2: Partial-thickness skin loss; Stage 3: Full-thickness skin loss; Stage 4: Full-thickness tissue loss with exposed bone/tendon.
-
Priority Intervention: Pressure relief via repositioning (q2h), use of pressure-relieving devices (specialty mattresses).
-
Supportive Care: Moist wound healing with appropriate dressings, nutritional support (protein, vitamins A & C, zinc), meticulous skin care, and patient/family education.
Side-by-Side Comparison!
| Intervention | Purpose/Rationale | Priority Level |
|---|
| Turning Schedule (q2h) | Addresses the root cause (pressure); prevents further injury. | FIRST PRIORITY |
| Appropriate Wound Dressing | Manages the existing wound; promotes moist healing environment. | Secondary (after pressure relief) |
| Nutritional Support | Provides substrates (protein) for tissue repair and immune function. | Tertiary (supportive/long-term) |
| Skin Assessment & Care | Prevents breakdown in other areas; monitors for complications. | Ongoing/Concurrent |
Anatomy, Physiology & Pharmacology Points
-
Pathophysiology: Sustained pressure (>32 mmHg) exceeds capillary closing pressure, blocking blood flow. Ischemia begins within 2 hours, leading to cell death.
-
Bony Prominences: Sacrum, heels, ischial tuberosities, trochanters, elbows, and occiput are most vulnerable.
-
Pharmacology (Supportive): Vitamin C supplements (collagen synthesis), Zinc supplements (cell proliferation). Analgesics (e.g., acetaminophen) may be needed for pain management during dressing changes.
Memory Tips
-
Mnemonic for Pressure Ulcer Prevention: "PRESS"
-
Position changes (q2h)
-
Relieve pressure (specialty surfaces)
-
Elevate heels off bed
-
Skin inspection daily
-
Support nutrition & hydration
-
Rule of Thumb: "If the pressure isn't off, the wound won't get better." Always think
cause first.
High-Frequency NCLEX Topics
Pressure ulcers are a
Core NCLEX topic, often tested on:
1.
Priority Setting: Identifying the first/nursing action (always pressure relief).
2.
Staging: Recognizing descriptions of Stage 1-4 ulcers.
3.
Contraindications: Knowing what NOT to do (e.g., don't massage, don't use heat lamps, don't use donut rings).
4.
Risk Assessment: Knowing the components of the Braden Scale.
Watch Out for Question Variations!
- Instead of asking for the priority intervention, the question might ask:
"The nurse is teaching a family member about home care for a patient with a pressure ulcer. Which statement by the family member indicates a need for further teaching?" (Correct answer would be something like, "I will massage the red area to improve circulation.").
- The scenario could shift to a
post-operative or
ICU patient, testing the same principle in a different context.
- Questions may combine pressure ulcers with other comorbidities like
Diabetes mellitus (DM) or
Peripheral vascular disease (PVD), emphasizing the need for meticulous assessment and slower healing.
