A client with an acute upper respiratory infection wants to know what diet he should follow to help treat his symptoms. Which diet would the nurse advise the client to follow?

A. Increased protein: While protein supports immune function, high-protein diet is not the priority in the acute phase of an upper respiratory infection. The client may also have decreased appetite, sore throat, or nasal congestion, making solid food difficult to consume. B. Soft, bland diet: This may be suitable for gastrointestinal issues or during recovery from oral or throat surgery, but it is not specifically indicated for upper respiratory infections. It also doesn't provide adequate hydration, which is a key focus during respiratory illness. C. Clear liquid: A clear liquid diet helps keep the client hydrated, soothes throat irritation, and is easier to tolerate during acute illness. Broths, juices, teas, and electrolyte fluids help thin mucus secretions and prevent dehydration, which supports symptom management and recovery. D. The client should be held NPO until symptoms improve: There is no reason to keep a client with an upper respiratory infection NPO unless they are experiencing vomiting or altered consciousness. Doing so would risk dehydration and slow recovery.
