When must written instructions be provided to a patient who has received radionuclide therapy?

Providing written instructions to a patient who has undergone radionuclide therapy is crucial for ensuring their safety and the safety of others around them. The rationale for requiring these instructions when another individual may receive an exposure greater than 1 mSv stems from the need to minimize radiation exposure to patients' family members, caregivers, and the general public.

Radionuclide therapy involves the administration of radioactive materials for diagnostic or therapeutic purposes. As the radioactive material is processed and excreted from the body, there is potential for radiation exposure to those nearby. By offering written instructions that inform the patient about safety precautions, such as maintaining distance from others, proper disposal of bodily fluids, and any post-treatment restrictions, patients can effectively manage their exposure levels.

In contrast, providing written instructions always, regardless of exposure level, does not account for situations where the radiation risk is minimal, potentially leading to unnecessary alarm or confusion. Limiting the provisions to only when requested or when the patient shows signs of distress does not address the proactive approach that healthcare providers must take to ensure the safety of others. Therefore, the correct approach emphasizes the need for guidance particularly in situations where there is a higher risk of exposure to others, ensuring the well-being of both the patient and those around
