A nurse is caring for a client who reports xerostomia following radiation therapy to the mandible. Which of the following is an appropriate action by the nurse?

A. Offer the client saltine crackers between meals. Saltine crackers are dry and salty, which can worsen symptoms of xerostomia (dry mouth) by further irritating and drying the oral mucosa. Moist, soft foods are more appropriate. B. Suggest rinsing his mouth with an alcohol-based mouth wash. Alcohol-based mouthwashes should be avoided in clients with dry mouth as they can exacerbate oral dryness and irritation. Alcohol-free rinses are recommended instead. C. Instruct the client on the use of esophageal speech. Esophageal speech is used in clients who have had laryngectomies, not those experiencing xerostomia. This intervention is unrelated to the client's current condition. D. Provide humidification of the room air. Using a humidifier adds moisture to the environment, which helps relieve oral dryness and makes the client more comfortable, especially during sleep or in dry indoor climates.
