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)

A. Wear a lead apron when providing care: Lead aprons help protect the nurse from radiation exposure when providing close care to a client with a sealed radiation implant. This is a standard safety precaution in managing patients receiving internal radiation therapy. B. Close the door to the client's room: Keeping the door closed limits unnecessary exposure to radiation for other clients and staff in the unit. It also helps maintain a controlled environment for infection and radiation safety. C. Place the client in a semi-private room: Clients with sealed radiation implants should be placed in a private room to minimize radiation exposure to other patients and staff. Semi-private rooms increase the risk of unnecessary exposure and are not recommended. D. This is an application of Time. The risk of radiation damage is cumulative. By restricting visits to 30 minutes per 24-hour period, the facility ensures that guests stay well below the threshold for accidental radiation injury. E. This is incorrect for two reasons. First, pregnant women and children under the age of 18 are generally prohibited from visiting a client with a radiation implant due to the high sensitivity of developing fetal and juvenile tissues. Second, even for authorized visitors, the safe distance is at least 6 feet (2 meters), not 3 feet.
