Rationale: The best nursing goal for an incontinent elderly client with skin excoriation is to ensure that the bed linen is always dry. This helps in preventing further skin breakdown and promoting skin integrity. Choice B, to frequently check the bed for wetness and keep it dry, may not address the issue of prevention if the linen is not consistently dry. Choice C, placing a rubber sheet under the client's buttocks, focuses more on protecting the mattress rather than addressing the client's skin condition directly. Choice D, keeping the patient clean and dry, is important but does not specifically address the preventive aspect of maintaining dry bed linen.
