Maintaining skin integrity would include:

Choice A: Speech therapist is correct, as they can assess and treat the patient's swallowing function and recommend appropriate diets and feeding strategies.

Choice B: Respiratory therapist is not correct, as they can help the patient with breathing problems and oxygen therapy, but not with nutrition.

Choice C: Physical therapist is not correct, as they can help the patient with mobility and exercise, but not with nutrition.

Choice D: Social worker is not correct, as they can help the patient with psychosocial and financial issues, but not with nutrition.

Choice A: Nutrition supplements is not a direct intervention for maintaining skin integrity, but rather a general measure to support the patient's overall health and healing.

Choice B: Consulting speech therapy is not relevant for maintaining skin integrity, but rather for addressing the patient's communication and swallowing needs.

Choice C: Assessing the skin and frequent repositioning is a correct intervention for maintaining skin integrity, as it can prevent pressure ulcers or bedsores by reducing friction, shear, and moisture on the skin.

Choice D: Ambulating the patient as much as possible is not a specific intervention for maintaining skin integrity, but rather a general measure to promote the patient's mobility and circulation.
