What limitation should be placed on visitors to a client undergoing brachytherapy?

The correct answer is based on safety considerations for both the patient undergoing brachytherapy and the visitors. Brachytherapy involves the placement of radioactive sources directly into or near the tumor, which means that there is a risk of radiation exposure.

Placing a limitation of one 30-minute visit per day helps to reduce the radiation exposure to visitors while still allowing family and friends to support the patient emotionally. This restriction is often established to ensure that the time spent in close proximity to the patient is limited, adhering to safety protocols for exposure to radiation.

While some facilities might have different specific guidelines, they generally follow the principle of minimizing exposure while accommodating the emotional and psychological needs of the patient. The choices that suggest unlimited visits or more frequent visits could lead to increased radiation exposure, which is contrary to established safety protocols in a healthcare setting.
