A nurse is providing teaching to a client who is postoperative following a partial glossectomy. Which of the following instructions should the nurse include in the teaching?

A partial glossectomy involves surgical removal of part of the tongue, often for treatment of oral cancer. This procedure significantly affects speech, swallowing, and airway protection. Postoperative care focuses on maintaining airway patency, promoting nutrition, preventing infection, and supporting communication needs. Because verbal communication may be impaired, alternative methods are essential for effective patient interaction and safety. A. Inspecting the mouth once each week is not adequate because postoperative oral surgery requires frequent monitoring for bleeding, infection, and wound healing complications. Daily or more frequent oral assessments are necessary in the early postoperative period. Weekly inspection may delay identification of serious complications. B. Using an alcohol-based mouthwash is contraindicated because it can cause significant irritation and pain to surgical tissues and delay healing. Alcohol-based products may also increase dryness and discomfort in the oral cavity. Instead, gentle saline or prescribed non-irritating rinses are recommended. C. Using text or pictures to communicate needs is appropriate because a partial glossectomy impairs speech ability. Alternative communication methods such as writing boards, picture charts, or electronic devices help ensure the client can express needs effectively and safely during recovery. D. Increasing intake of dense, high-fiber foods is inappropriate in the immediate postoperative period because the client may have difficulty chewing and swallowing. Post-glossectomy diets are typically soft or liquid to reduce the risk of aspiration and promote safe nutrition. High-fiber, dense foods would be difficult to manage and potentially unsafe.
