Final answer:
The incorrect statement about mucositis is that the client should use an alcohol-based mouth rinse. Alcohol can exacerbate mucositis, so alcohol-free options are better for sensitive oral tissues affected by this condition.
Step-by-step explanation:
The statement indicating that the client needs more teaching about mucositis is: "I should use an alcohol-based mouth rinse to kill bacteria." This is incorrect as alcohol-based mouthwashes can aggravate mucositis, which is an inflammation and ulceration that occurs in the mouth, often as a reaction to chemotherapy or radiation therapy. Alcohol-free mouthwashes are preferable since they are less irritating to sensitive oral tissues. Teaching should emphasize the avoidance of irritants, gentle oral hygiene with a soft-bristled toothbrush, and alcohol-free mouth rinses.
Clients should be aware that good oral hygiene is important for managing mucositis, which may include rinsing with water after meals and using a soft-bristled toothbrush. Even though flossing may sometimes be contraindicated when oral tissues are very irritated or bleeding, it might still be possible under the guidance of a healthcare provider. Therefore, a blanket statement about not using floss is not universally accurate without individual assessment.
