A nurse is caring for a client who has had an allogeneic hematopoietic stem-cell transplant. Which of the following infection-control precautions should the nurse use while caring for this client?

A. Chronic drainage of fluid through the incision site:
While chronic drainage of fluid through the incision site can be a sign of wound complications, such as infection or poor wound healing, it is not as specific an indicator of impending wound dehiscence as the patient's report of "something giving way."

B. Report by patient that something has given way:
A patient reporting that something has given way is a significant indicator of potential wound dehiscence. Wound dehiscence refers to the partial or complete separation of the layers of a surgical wound, which can occur due to various factors such as poor wound healing, infection, or increased intra-abdominal pressure. Patients may describe a sensation of "something giving way" or "popping" if the wound starts to separate.

C. Drainage that is odorous and purulent:
Odorous and purulent drainage from an incision site may indicate an infection, which can contribute to wound dehiscence. However, this finding alone may not necessarily indicate immediate wound dehiscence.

D. Protrusion of visceral organs through a wound opening:
Protrusion of visceral organs through a wound opening is a severe complication known as evisceration, which is the most advanced stage of wound dehiscence. While this finding is indicative of a significant wound complication, it typically occurs after the initial separation of wound layers. Therefore, it is not an early sign that would alert the nurse to potential wound dehiscence

A) Exposed bone: Exposed bone is a manifestation of a stage 4 pressure ulcer, where full-thickness skin loss occurs, exposing muscle, tendon, or bone. In stage 3 pressure ulcers, the skin loss extends into the subcutaneous tissue, but it does not reach the level of exposing underlying structures like bone.

B) Blood-filled blisters: Blood-filled blisters can occur in various stages of pressure ulcers, but they are not specific to stage 3. They may be present in stage 1 or stage 2 pressure ulcers as well.

C) Necrotic subcutaneous tissue: This is the correct manifestation of a stage 3 pressure ulcer. Stage 3 pressure ulcers involve full-thickness skin loss with visible necrosis or damage to the subcutaneous tissue. The ulcer may appear as a deep crater with or without undermining of adjacent tissue.

D) Partial-thickness skin loss: Partial-thickness skin loss is characteristic of stage 2 pressure ulcers, where the ulcer extends through the epidermis and into the dermis but does not involve deeper tissue layers like the subcutaneous tissue.
