Correct Answer is A
Explanation
Exposing the affected area to air. To maintain skin integrity, the nurse should advise the client to expose the affected area to air.
Barrier garments, such as liners and protective pants, can trap moisture and irritate the skin, which can lead to skin breakdown. Exposing the affected area to air can help keep the skin dry and prevent skin breakdown.
B is not the correct answer because the application of moisture sealant can help protect the skin and prevent skin breakdown.
C is not the correct answer because using an electric room deodorizer is not related to maintaining skin integrity.
Correct Answer is D
Explanation
Diarrhea. A client who is recovering from bariatric surgery and is eating from a portable commode is at risk for diarrhea. Diarrhea can cause fluid and electrolyte imbalances, leading to dehydration, which can be life-threatening, especially in the immediate postoperative period.
Option A, impaired mobility, would not be a priority concern in the immediate postoperative period for this client.
Option B, impaired gas exchange, is not related to the situation.
Option C, self-care deficit, maybe a concern but is not as significant as diarrhea in the immediate postoperative period.
