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

The correct answer is B: White coating in the mouth. This is indicative of oral thrush, a common side effect of inhaled corticosteroids like fluticasone. The nurse should instruct the client to report this to the provider as it may require treatment. Increased appetite (A), sedation (C), and dry oral mucous membranes (D) are not typically associated with fluticasone/salmeterol and are less concerning compared to oral thrush. It's important for the nurse to prioritize potential adverse effects that directly impact the client's health and require medical attention.
