A patient with prostate cancer is undergoing brachytherapy using radioactive seeds. Which of the following precautions should the nurse educate the patient about during their treatment?

Choice A rationale Brachytherapy involves the internal implantation of radioactive isotopes directly into the prostate gland. These seeds emit low energy gamma or x-ray radiation that gradually decays over several months. Because the patient is a source of radiation, they must maintain a distance of at least six feet from pregnant women and children. This precaution prevents accidental ionizing radiation exposure to developing tissues and vulnerable populations while the radioactive material is at its peak therapeutic activity level. Choice B rationale Close physical contact such as hugging and kissing should be strictly limited or avoided during the initial period following radioactive seed implantation. Although the radiation travel distance is short, prolonged skin-to-skin contact increases the cumulative dose of radiation received by family members. Nurses must emphasize that while brief contact might be low risk, the cumulative effect of frequent close proximity could lead to unnecessary and potentially harmful radiation exposure for healthy individuals living with the patient. Choice C rationale Special precautions are necessary for waste disposal and the handling of body fluids because radioactive materials can be excreted or dislodged. If a seed is passed in the urine, it must be handled with forceps and stored in a lead container. Normal disposal methods for linens or bandages are insufficient if contamination is suspected. Proper education ensures that the environment remains safe and that any expelled radioactive sources are contained according to strict nuclear regulatory guidelines. Choice D rationale Resuming normal activities immediately is contraindicated due to the physical nature of the surgical implantation and the presence of internal radiation. Strenuous exercise or heavy lifting can cause the seeds to shift from their precise anatomical locations, reducing the efficacy of the targeted cancer treatment. Furthermore, the patient may experience localized inflammation and urinary symptoms that require a period of rest and monitoring to ensure there are no acute complications like hematuria or urinary retention.
