Which safety principle should a nurse observe when caring for a patient with an internal radiation implant?

• A. Limit the time with the client to 1 hour per shift
• B. Do not allow pregnant women into the client's room
• C. Remove the dosimeter badge when entering the client's room
• D. Individuals younger than 16 years old may be allowed to go in the room as long as they are 6 feet away

Answer: (B)

Protecting fetal development from ionizing radiation is the focus when caring for someone with an internal radiation implant. The radioactive source is inside the patient, and exposure to others, especially a developing fetus, can cause harm. Because pregnancy increases sensitivity to radiation, the safest practice is to prohibit pregnant women from entering the room. This aligns with safety guidelines to shield reproductive health. Time and distance help reduce exposure, but they do not replace the need to avoid exposing a fetus entirely. The dosimeter badge should always be worn to monitor exposure, and removing it is dangerous. Visitors under 16 and others at a distance are still subject to exposure risk and are typically restricted by policy; the strongest safeguard is not allowing pregnant individuals into the room.
