Question 3 of 5
Seven days ago, a 45-year-old female client had an ileostomy. She is self-sufficient and well otherwise. Which of the following long-term objectives would be unrealistic?
Correct Answer: A
Rationale: Because of the location of an ileostomy, the client will not be able to control the evacuation of her bowels. The ileostomy will drain liquid stool continuously. The client should be able to return to a normal, well-balanced diet. She should avoid foods that cause diarrhea or excessive gas production, and she should eat small meals. The client should be able to resume sexual activity. She will be able to wear a pouch. The client has no other health or mental problems and should be able to manage her own ileostomy.
