A nurse is caring for a client who has lung cancer and has a sealed radiation implant. Which of the following actions should the nurse take? (Select all that apply.)

Rationale: A. Closing the door helps contain radiation and protect staff and visitors from exposure. B. A semi-private room is contraindicated; the client must be in a private room to protect others from radiation exposure. C. Wearing a lead apron during direct care reduces exposure to scatter radiation. The nurse should also avoid standing directly at the radiation source. D. Limiting visitors to 30 minutes per day minimizes radiation exposure time. The principle of "time, distance, and shielding" guides radiation safety. E. Pregnant visitors should not enter the client’s room at all, as fetal tissue is highly sensitive to radiation.
