A nurse is providing discharge teaching to a client who has asthma and a new prescription for fluticasone/salmeterol. For which of the following adverse effects should the nurse instruct the client to report to the provider?

A. A white coating in the mouth may indicate oral candidiasis (thrush), a common adverse effect of inhaled corticosteroids like fluticasone. The client should be instructed to report this and to rinse the mouth after each use to help prevent it. B. Increased appetite is not a typical side effect of this combination medication. C. Sedation is not associated with fluticasone/salmeterol; in fact, salmeterol may cause nervousness or tremors. D. Dry oral mucous membranes can occur with inhalers, but they are usually mild and do not require reporting unless severe.
