A nurse is providing teaching to a client who is undergoing radiation therapy and has stomatitis. Which of the following responses by the client indicates an understanding of the teaching?

Choice A reason: "I should gargle with an alcohol-based mouthwash to kill germs”. This statement is not appropriate. Using an alcohol-based mouthwash is not recommended for a client with stomatitis. Alcohol can be irritating to the already inflamed mucous membranes and may worsen the condition. Instead, the client should use a mild, non-alcohol-based mouthwash or rinse as prescribed by the healthcare provider. Choice B option "I should limit my intake of dairy products to prevent nausea." This statement is not appropriate. While some clients may experience nausea during radiation therapy, limiting dairy products is not specifically related to stomatitis management. The client should follow any dietary recommendations provided by the healthcare provider or a registered dietitian to address nausea or other dietary concerns. Choice C option "I should moisten my lips with lemon-glycerine swabs." This is incorrect because lemon-glycerine swabs can be drying and irritating to the oral mucosa, which may exacerbate stomatitis symptoms. Instead, using a gentle, non-irritating lip balm or petroleum jelly is preferred. Choice D option "I should use a soft-bristle toothbrush to clean my teeth after meals." This response indicates an understanding of the teaching because a soft-bristle toothbrush is gentle on the gums and oral tissues, which is important for a client with stomatitis, as it helps to minimize irritation and injury.
