Explanation

The standard of care is to irrigate a pressure ulcer with normal saline during each dressing change.
Normal saline is an isotonic, non-cytotoxic solution that effectively cleanses the wound without damaging the fragile granulation tissue essential for healing.
Timing irrigation with dressing changes minimizes disruption to the wound bed, prevents significant temperature drops, and reduces the risk of introducing new contaminants.
The frequency of dressing changes and irrigation is determined by a clinical assessment of the wound, particularly the amount of exudate, not by a rigid, routine schedule like 'every shift'.

Option B: Irrigating a bed sore 'every shift' is too frequent and can disrupt the healing process. It can traumatize newly forming tissue and lower the wound bed temperature.
Option C: While normal saline is the correct solution, using it 'in each shift' is an inappropriate frequency for most pressure ulcers. This can interfere with the stable environment needed for healing.
Option D: This option combines the correct solution (normal saline) with an incorrect, excessive frequency ('in each shift'). Routine, frequent irrigation can delay wound healing.

Clinical Relevance

Nursing practice connection: Knowing Principles of pressure ulcer (bed sore) irrigation, including appropriate solution and frequency helps nurses interpret findings accurately and avoid errors in routine assessment, medication administration, and patient teaching.
Proper wound irrigation is a fundamental nursing skill that directly impacts patient outcomes by preventing infection and promoting healing.
Nurses must perform a thorough wound assessment at each dressing change to make clinical judgments about the need for and frequency of irrigation, rather than adhering to a rigid schedule.
What if? If the pressure ulcer had a stable, dry eschar (necrotic tissue) on the heel, the standard of care would be to keep it clean and dry and NOT irrigate it, as the eschar serves as a natural biological cover.

How to Approach the Question

First, identify the core of the question: it asks for the 'appropriate' method for bed sore irrigation.
Analyze the options to find the key variables. Notice that the options differ in two main aspects: the solution used and the frequency of irrigation.
Recognize that 'normal saline' is the standard, non-cytotoxic solution for cleaning most wounds. This makes the frequency the primary deciding factor.
Compare the proposed frequencies: 'with dressing change/every day' versus 'every shift'.
Apply the principle of wound healing that a stable, undisturbed environment is optimal. Frequent interventions (every shift) are disruptive and can impede healing.
Conclude that irrigating during dressing changes strikes the correct balance between keeping the wound clean and protecting the delicate healing process.
