A nurse is admitting a client who has a wound infected with methicillin-resistant Staphylococcus aureus (MRSA). Which of the following types of precautions should the nurse plan to initiate?

The correct answer is choice B. Necrotic subcutaneous tissue.

Choice A rationale:

Partial-thickness skin loss (Choice A) is characteristic of a stage II pressure ulcer, not a stage III ulcer. A stage II pressure ulcer involves the loss of the epidermis and possibly the dermis, resulting in a shallow open ulcer with a red-pink wound bed.

Choice B rationale:

Necrotic subcutaneous tissue is a manifestation of a stage III pressure ulcer. A stage III ulcer involves full-thickness skin loss where subcutaneous fat may be visible, but exposed bone or muscle is not yet present. Necrotic tissue in the wound bed indicates a more advanced level of tissue damage and the need for appropriate wound care to promote healing.

Choice C rationale:

Blood-filled blisters (Choice C) are not specific to pressure ulcers and are more commonly associated with friction or shear forces. These blisters are not indicative of a stage III pressure ulcer, which involves visible full-thickness tissue loss.

Choice D rationale:

Exposed bone (Choice D) is a characteristic of a stage IV pressure ulcer, not a stage III ulcer. A stage IV ulcer involves extensive tissue loss with exposure of muscle, tendon, or bone. This represents a severe level of tissue damage and requires intensive wound care and management.

The correct answer is choice A. Transparent dressing.

Choice A rationale:

Transparent dressings are appropriate for stage I pressure ulcers. These dressings provide a moist environment that promotes healing and protects the wound from external contaminants. They are also transparent, allowing the nurse to monitor the wound without removing the dressing. As stage I pressure ulcers involve intact skin with non-blanchable redness, these dressings aid in preventing friction and shear forces that could exacerbate the injury.

Choice B rationale:

Alginate dressings (Choice B) are not suitable for stage I pressure ulcers. Alginate dressings are highly absorbent and are generally used for wounds with moderate to heavy exudate, such as infected wounds or those with necrotic tissue. They may not be the best choice for a stage I pressure ulcer, which is characterized by superficial skin involvement without exudate or necrosis.

Choice C rationale:

Hydrogel dressings (Choice C) are beneficial for wounds with minimal to no exudate, but they are more appropriate for partial-thickness wounds, burns, or dry wounds. They provide a moist environment and promote autolytic debridement. However, in the case of a stage I pressure ulcer, where the skin is intact and there is no exudate, hydrogel dressings may not be the ideal choice.

Choice D rationale:

Wet-to-dry gauze dressings (Choice D) involve placing moist saline gauze onto a wound bed and allowing it to dry before removal. This method is used for mechanical debridement of wounds with necrotic tissue, and it's not suitable for a stage I pressure ulcer. In fact, using wet-to-dry dressings on a superficial wound could cause trauma and hinder healing.
