The nurse is providing discharge instructions for a female client after receiving radioactive iodine treatment. Which of the following information should the nurse include in the teaching?

"You will immediately start thyroid replacement therapy after radioactive iodine treatment."

"Your partner can feed breast milk to your baby if you pump it."

"You can try to get pregnant 2 months after the treatment."

"You need to avoid close contact with others until you the doctor determines you are no longer emitting radiation from your body."

Answer and Explanation

The Correct Answer is D

A. While many patients who receive radioactive iodine treatment (RAI) for hyperthyroidism may require thyroid replacement therapy afterward, this is not always immediate. The body’s response to the treatment varies, and thyroid function will need to be monitored. The initiation of thyroid replacement therapy depends on the individual's thyroid levels after treatment.
B. Radioactive iodine is contraindicated during breastfeeding because the iodine can pass into the breast milk, potentially exposing the infant to radiation. Mothers are usually advised to stop breastfeeding and to pump and discard milk for a period after the treatment (usually several weeks).
C. The general recommendation is that women should wait at least 6 months after receiving radioactive iodine treatment before trying to become pregnant, as the radiation could potentially affect fetal development during the first few months following the treatment.
D. After receiving radioactive iodine treatment, patients should limit contact with others (especially pregnant women and young children) for a period of time to reduce the risk of radiation exposure to others. This period varies based on the dose of radioactive iodine used, but patients are typically advised to follow specific precautions until their radiation levels have decreased to a safe level.

Correct Answer is B

Explanation

A. Schizophrenia itself does not typically affect thyroid diagnostic test results. However, some medications used to treat schizophrenia may potentially influence thyroid function, but the diagnosis alone is not a direct factor.
B. Oral contraceptives can affect thyroid function tests. They may increase the levels of thyroid-binding globulin (TBG), which could result in falsely elevated total thyroid hormone levels. This can affect the interpretation of thyroid function tests, such as TSH, T3, and T4.
C. Vitamin C does not typically interfere with thyroid function tests. It is generally considered safe and does not directly affect the results of thyroid diagnostic tests.
D. Obesity does not directly interfere with thyroid diagnostic tests. However, thyroid disorders, especially hypothyroidism, are more common in individuals with obesity, so it may be a consideration in assessing thyroid function.

A. Active rewarming may increase oxygen demands. B. Electric cords from heating pads can be a choking hazard. C. Heating pads could cause tissue burns. D. Warm blankets are more comforting for the client.

Correct Answer is C

Explanation

A. The statement active rewarming may increase oxygen demands is true for some conditions, like hypothermia, but it is not the primary reason to avoid heating pads for a client with myxedema. While rewarming can increase oxygen demands, the primary concern with heating pads is the risk of burns due to impaired thermoregulation in myxedema.
B. This is not relevant to the scenario. The concern with heating pads is not about choking hazards but about burns and safe rewarming.
C. In myxedema, the body’s ability to regulate temperature and respond to thermal stimuli is impaired due to severe hypothyroidism. This puts the client at a higher risk for burns if heating pads are used. Using warm blankets instead of heating pads ensures a safer, more gradual rewarming process.
D. While warm blankets may indeed be more comforting, the primary reason for using them instead of heating pads is to avoid the risk of burns due to impaired temperature regulation.
