Which dietary advancement should be made first after the return of bowel sounds postoperatively?

Rationale: A. After the return of bowel sounds postoperatively, clear liquids (e.g., water, broth, tea, clear juice) are introduced first. This allows the gastrointestinal tract to gradually resume function and ensures the client can tolerate fluids without nausea, vomiting, or distention. B. A soft diet is introduced later once the client tolerates clear liquids and then full liquids, as it is more complex to digest. C. A regular diet is not started immediately after surgery; the gut needs gradual reintroduction to food. D. Full liquids can be given after clear liquids are tolerated, as they are more substantial and include milk-based or blended foods.
