A nurse in the emergency department is caring for female client. Exhibits Which of the following instructions should the nurse include in the teaching? (Select All that Apply.)

A. Schedule rest periods: The client's metabolism is "running a marathon," leading to exhaustion. Frequent rest lowers the metabolic demand on the heart. B. Allow 1 month following radioactive iodine therapy for manifestations to subside: It typically takes 6 to 8 weeks or longer for the full effects of RAI therapy to manifest. One month may be too soon to expect full symptom resolution. C. Flush the toilet with the lid closed: This is a specific precaution for clients receiving radioactive iodine (RAI) therapy. Since the radiation is excreted in body fluids (urine/stool), flushing with the lid closed prevents the aerosolization of radioactive particles. D. Drink black tea to reduce diarrhea: Tea contains caffeine, a stimulant. Stimulants increase heart rate and metabolism, which are already dangerously high in this client. E. Keep a record of food intake and weight: Due to the rapid weight loss, the nurse must monitor nutritional status to ensure the client is consuming enough calories (often a high-calorie diet is needed) to maintain weight.
