Final answer:
The best wound care option for a patient with a Stage 3 pressure ulcer that has necrotic tissue, moderate exudate, and bone visible is B. Enzymatic debridement. This method removes necrotic tissue effectively, which is essential to prevent infection and promote healing.
Step-by-step explanation:
A patient with a Stage 3 pressure ulcer that has necrotic tissue, moderate exudate, and visible bone requires careful intervention to promote healing and prevent infection. Considering the options given, the best wound care option for this scenario would likely be B. Enzymatic debridement. Enzymatic debridement involves the application of a topical preparation to degrade and remove necrotic tissue without harming viable tissue, which is crucial in the presence of necrosis and potential infection risks like gas gangrene caused by Clostridium spp. Calcium alginate dressings can be used for wounds with exudate; however, they do not address necrotic tissue. Hydrogel dressings can keep the wound moist and promote autolytic debridement, but are typically used for less severe necrotic conditions. Transparent films are not suitable for Stage 3 ulcers with heavy exudates and necrotic tissue, as they do not absorb drainage well and do not debride.
