Which of the following interventions is most effective in preventing the development of pressure ulcers in older adults with limited mobility?
Correct Answer: C
Rationale: The correct answer is C because regular repositioning every 2 hours, along with the use of pressure-relieving devices, is the most effective intervention to prevent pressure ulcers in older adults with limited mobility. Repositioning helps to redistribute pressure, reducing the risk of tissue damage. Pressure-relieving devices like cushions or mattresses further help to alleviate pressure points.
Choice A is incorrect because strict bed rest and minimal repositioning can actually increase the risk of pressure ulcers by concentrating pressure on specific areas. Choice B is incorrect as high-protein diets and supplements alone do not address the primary cause of pressure ulcers, which is prolonged pressure on the skin. Choice D is incorrect because leaving wounds uncovered can increase the risk of infection and hinder the healing process.
