Final answer:
The recommended position for a client during internal radiation therapy is determined by the clinician and varies based on treatment specifics; often a supine position is used.
Step-by-step explanation:
The recommended client position during internal radiation therapy varies depending on the specific procedure and the area of the body that is being treated. In some cases, a supine position is utilized, which means the person is lying on their back with arms and legs extended at their sides. Each treatment plan is tailored to the individual patient, and positioning will be determined by the clinician based on the best access and safety considering the location of the tumor and the radiation source.
