During chemotherapy, which nursing intervention is most likely to decrease stomatitis pain?

• A. Recommending that the client discontinue chemotherapy
• B. Providing a hydrogen peroxide and water mouth rinse
• C. Monitoring the client's platelet and leukocyte counts
• D. Checking regularly for signs and symptoms of stomatitis

Answer: (B)

Stomatitis from chemotherapy is painful because the mucous lining becomes inflamed and ulcerated, so keeping the mouth clean and free of debris helps reduce irritation and supports healing. A diluted hydrogen peroxide and water mouth rinse provides an antiseptic action that helps remove slough and bacteria from the mouth, lowering the risk of secondary infection in the ulcers and easing pain. Use it as directed, typically diluted with water and not swallowed, to avoid additional irritation.

Other interventions focus on monitoring or stopping treatment or identifying problems, which don’t directly alleviate the pain of the mucosal injury. Regular checks for stomatitis are important for early detection, but they don’t actively reduce the pain itself.
