Based on the information provided within the question it can be said that if the client makes any of the following statements then they need further teaching from the nurse, "I can resume swimming laps three times a week",
"I will call my HCP if I have green drainage"
, or "I am glad I can lift whatever I want"
. This is because, the t-tube should not be immersed in water, green drainage is normal and does not require a call to HCP, and no excercise or heavy lifting should be done for a minimum of 5 weeks.
This might not be detailed enough but she can have a healthy diet and workout to keep her skinny and fit while also being healthy. I hope this helps but u might have to add more detail to your answer than what i put.
