Final answer:
The best measure to evaluate skin integrity by discharge is the Condition of the skin over bony prominences, as it directly reflects the skin's status and effectiveness of interventions.
Step-by-step explanation:
The best measure in evaluating the outcome of maintaining skin integrity by discharge is D) Condition of the skin over bony prominences. This direct observation provides clear, visual evidence of whether or not skin breakdown has occurred. Measures such as A) The client's ability to reposition self in bed, and B) Pressure-relieving mattress on the bed, are important for preventing pressure ulcers but they do not directly assess the condition of the skin. C) Percent intake of a diet high in protein is supportive in maintaining skin integrity, however, it also does not directly assess skin condition.
The key factors involved in preventing and treating bedsores, or decubitus ulcers, include repositioning patients regularly, using support surfaces like pressure-relieving mattresses, and ensuring adequate nutritional support, specifically with a diet high in protein. Evaluating the condition of the skin, especially over bony areas, provides immediate feedback on the effectiveness of these interventions and the current status of skin health, essential for achieving the desired outcome.
