Answer: B - The nurse should instruct the client to take the medication at the same time each day, preferably in the morning before breakfast. This is to allow the body to absorb the drug without the interference of other medications and foods. Bradycardia, cold intolerance, and hypothermia are the side effects of antithyroid medications. Consumption of foods rich in calcium, such as milk and cheese, can disrupt the action of thyroid medications; therefore, these foods should be eaten hours after taking the thyroid medications, in moderate amounts.
