Step-by-step explanation:
The nurse prepares a client for placement of internal radiation by providing an indwelling urinary catheter and a tap water enema. This is done to reduce radiation exposure to the bladder and rectum. The indwelling urinary catheter helps to divert the urine away from the bladder, reducing the risk of radiation damage to the bladder. The tap water enema helps to clear the bowels and reduce radiation exposure to the rectum.
