A nurse caring a bedridden patient with a pressure ulcer, 2 hourly position changes and massaging & rubbing the back but pressure sore does not heal. What is the expected problem?

1. A

   Do not apply cream

2. B

   Inadequate amount of carbohydrate

3. C

   Inadequate amount of protein

4. D

   Massaging

Explanation

Listen in Hindi

• Protein is the most critical macronutrient for wound healing, providing the essential amino acids needed for tissue regeneration, collagen synthesis, and immune cell production.
• A state of negative nitrogen balance, caused by inadequate protein intake, directly impairs all phases of wound healing, making it the most likely underlying problem when an ulcer fails to progress.
• Patients with pressure ulcers have increased metabolic demands and protein requirements to support the healing process.
• While other factors are involved, a protein deficiency is a fundamental barrier that cannot be overcome by local wound care or pressure relief alone.

Why Other Options Were Wrong

• Option A: The absence of cream is a factor in local wound care, but it is not the primary reason for a complete failure to heal. Systemic factors like nutrition are far more critical.
• Option B: Carbohydrates are important as an energy source to 'spare' protein for healing. However, a deficiency in protein itself is a more direct and critical cause of impaired tissue synthesis.
• Option D: Massaging over bony prominences or reddened areas is a contraindicated practice that causes further tissue damage. While this is a significant error in the care being provided, the question asks for the problem causing the failure to heal. The most fundamental reason for the body's inability to repair itself is a lack of essential building blocks (protein).

Clinical Relevance

• Nursing practice connection: Use the key finding related to Factors affecting wound healing, specifically the nutritional requirements for pressure ulcer management to guide bedside assessment, documentation, and the next nursing action.
• Nurses play a vital role in preventing and managing pressure ulcers, which includes performing comprehensive skin assessments and nutritional screenings (e.g., monitoring weight, pre-albumin levels).
• It is a critical patient safety principle to know that massaging bony prominences is contraindicated. Nurses must educate other staff and family members about this to prevent iatrogenic harm.
• Collaboration with a dietitian is essential to develop a nutritional plan for patients with non-healing wounds, often involving high-protein diets and supplements.

How to Approach the Question

• First, identify the core clinical problem in the stem: a pressure ulcer is not healing.
• Next, analyze the interventions mentioned: '2 hourly position changes' (correct) and 'massaging & rubbing the back' (incorrect and harmful).
• Evaluate the options in the context of the physiology of wound healing. Ask yourself, 'What is most essential for the body to build new tissue?'
• Recognize that systemic factors, like nutrition, are often the root cause when wounds fail to heal despite local care.
• Differentiate between an incorrect action (massaging) and an underlying physiological deficit (lack of protein). The failure of the healing process itself points more strongly to the physiological deficit as the 'expected problem'.

Concept Tested & Keywords

• Concept Tested: Factors affecting wound healing, specifically the nutritional requirements for pressure ulcer management.
• Stem keywords: bedridden patient, pressure ulcer, not heal, position changes, massaging
• Lead-in keywords: expected problem
• Clinical cues: The key clinical cue is 'pressure sore does not heal' despite the implementation of some care measures (position changes). This suggests an underlying systemic problem is preventing the body's natural repair processes.
