A nurse is assessing a client who wears partial dentures and reports mouth pain. Which of the following actions should the nurse take?

A. Provide the client with an alcohol-based mouthwash: Alcohol-based mouthwashes can cause oral mucosa dryness and irritation, worsening mouth pain. They are not recommended for clients with oral discomfort or partial dentures. B. Instruct the client to brush their remaining teeth with a firm toothbrush: A firm toothbrush can damage gum tissue and increase discomfort, especially in a client already experiencing pain. A soft-bristled toothbrush is safer for maintaining oral hygiene without causing trauma. C. Advise the client to rinse their mouth and dentures after each meal: Rinsing after meals removes food particles and prevents bacterial buildup, reducing irritation and risk of infection. This promotse oral health and comfort in clients with partial dentures. D. Swab the client's mouth with lemon-glycerin sponges at bedtime: Lemon-glycerin swabs can dry out the mucous membranes and cause irritation. They are no longer recommended in oral care because they worsen discomfort rather than relieve it.
