We encourage the patient to cough and deep breathe after surgery to prevent:

Choice A reason: Serving food in sealed packaging can help alleviate the client's fears of poisoning, as the intact seals provide visual assurance that the food has not been tampered with.

Choice B reason: While serving warm foods with lids may keep the food warm, it does not necessarily provide the same level of reassurance against the fear of poisoning as sealed packaging does.

Choice C reason: Serving the same food as others may not be effective if the client's delusions include beliefs that they are being specifically targeted.

Choice D reason: Although serving the client's favorite foods in an attractive arrangement may be appealing, it does not address the specific paranoid delusion of food being poisoned.

Choice A reason: Provision of home care is not part of the immediate postoperative phase described during preoperative teaching.

Choice B reason: The decision for surgery until transfer to surgery is part of the preoperative phase, not the postoperative phase.

Choice C reason: Admission to the Post Anesthesia Care Unit (PACU) until recovery is the correct description of the postoperative phase, where the patient is monitored as they recover from anesthesia.

Choice D reason: Transfer to surgery until transfer to PACU describes the transition from preoperative to intraoperative phases, not the postoperative phase.
