A nurse is caring for a patient who is 2 days postoperative after abdominal surgery. What nursing intervention would be important to promote wound healing at this time?

Correct Answer: B

Rationale: Assist in moving to prevent strain on the suture line' promotes healing. Day 2 e.g., inflammation needs support e.g., 50% less tension unlike 'pain meds' , comfort e.g., not direct healing. 'Mild fever normal' informs e.g., not action. 'Scar limits movement' is late e.g., irrelevant now. A nurse aids e.g., Lift, don't pull' per suture care, a physiological need. The text prioritizes strain relief, making the correct, healing intervention.

Correct Answer: D

Rationale: Applications of heat or cold to large areas of the body cause systemic responses' is key. Large e.g., 50% body shifts e.g., temp ±1°C unlike 'decreases tolerance' , true but minor e.g., not systemic. 'Neck, perineum less sensitive' reverses e.g., more. 'Open skin less sensitive' flips e.g., hypersensitive. A nurse considers e.g., Whole-body effect' per 80% risk, a physiological must. The text flags systemic impact, making the correct, critical consideration.

Correct Answer: A

Rationale: Repositioning every hour is the correct answer as it helps redistribute pressure, reducing the risk of pressure ulcer formation. This action prevents prolonged pressure on specific areas, improving blood flow and tissue oxygenation. Providing a low-protein diet (B) is incorrect as protein is essential for wound healing. Ensuring a generous fluid intake (C) is important for overall skin health but alone does not prevent pressure ulcers. Massaging reddened areas on the sacrum (D) can actually worsen skin damage by increasing friction and pressure on vulnerable skin.

Correct Answer: C

Rationale: The correct answer is C: Impaired physical mobility. Impaired physical mobility can lead to pressure ulcers and skin breakdown due to prolonged pressure on specific areas. This etiology directly impacts skin integrity. Noncompliance with turning schedule (A) can contribute to skin breakdown but is not the primary etiology. Poor nutritional intake (B) can affect wound healing but is not directly related to skin integrity. Impaired adjustment (D) is not a recognized etiology for impaired skin integrity.

Correct Answer: A

Rationale: The purpose of a wet-to-dry dressing is to mechanically debride the tissue, which involves removing dead or infected tissue through the physical action of the dressing. First, the wet dressing helps to soften and loosen the necrotic tissue. Then, as the dressing dries, it adheres to the dead tissue and upon removal, it pulls the debris away, promoting a clean wound bed. This process facilitates wound healing by promoting tissue regeneration. Other choices are incorrect because reducing local tissue maceration and preventing bacterial growth are not the primary purposes of a wet-to-dry dressing. Additionally, preserving granulation tissue is not the intended goal of this dressing method.
