Step-by-step explanation:
After a gastrectomy, the nurse should include several instructions for the client's postoperative care. Gradually reintroducing solid foods into the diet is important to allow the client's digestive system to adjust and prevent complications. However, the client should avoid deep breathing exercises to prevent strain on the incision. It is also important for the client to gradually resume normal activities without any restrictions.
