A nurse is planning care for a client who has hyperthyroidism and is receiving radioactive iodine (radioiodine). Which of the following statements by the nurse regarding special precautions is appropriate?

A. "You will need to remain at the hospital for the entire time the radioiodine is radioactive.": The client typically only needs to stay in the hospital for a short period after receiving radioactive iodine, not for the entire duration. Most of the radioactivity is eliminated through urine and bodily fluids over time. B. "A low fiber diet will be necessary.": A low fiber diet is not specifically required for clients receiving radioactive iodine. Some clients may experience gastrointestinal symptoms such as diarrhea, and a low fiber diet could worsen this. C. "Additional immunizations will be needed for full protection.": Radioactive iodine therapy targets the thyroid gland and does not inherently impact the immune system in a way that would necessitate additional immunizations for protection against common infections. D. "You will need to use a bathroom separate from other household members.": This is an appropriate precaution. Radioactive iodine can be excreted in urine, and using a separate bathroom helps reduce exposure to others, especially in the first few days after treatment.
