What important precaution should a nurse teach a female client receiving radioactive iodine for hyperthyroidism?

Teaching a female client receiving radioactive iodine for hyperthyroidism the importance of avoiding close contact with young children is crucial due to the potential risk of radiation exposure. Radioactive iodine treatment involves taking a radioactive form of iodine, which is absorbed by the thyroid gland. This radiation can be excreted in bodily fluids and can pose a risk to others, particularly vulnerable populations such as young children, who are more sensitive to radiation effects.

Prolonged close contact—such as hugging, holding, or sharing a bed with children—should be minimized to reduce the risk of radiation exposure to them. Following treatment, healthcare providers typically recommend maintaining a safe distance from others, especially young children and pregnant individuals, for a period of time to minimize any potential risks.

In contrast, while resuming breastfeeding, avoiding public transport, and wearing a mask may be relevant considerations in certain contexts, they do not address the primary concern about the excretion of radioactive iodine and its potential danger to children specifically. The emphasis on limiting close physical contact directly addresses the safety of those who are most likely to be affected by the radiation.
