A client has recently been diagnosed with type II endometrial cancer and will be treated with brachytherapy. What statement by the client indicates a need for further education on this treatment?

"I have to be alone in the room during treatment, so I don't expose others."

"Each treatment will take only 20 to 30 minutes."

"I can get up and walk around or read in a chair during the treatments."

"I need to report any heavy vaginal bleeding or severe diarrhea."
