Levothyroxine sodium is prescribed for a client with hypothyroidism. The nurse should instruct the client to report which symptom because it indicates that the client is taking too much levothyroxine sodium?

Choice A reason: Constipation is typically a symptom of hypothyroidism, not hyperthyroidism. If a client is taking too much levothyroxine, they are more likely to experience symptoms of hyperthyroidism, such as diarrhea, rather than constipation. Choice B reason: Intolerance to cold is a common symptom of hypothyroidism, indicating that the thyroid hormone levels are too low. If the client is taking too much levothyroxine, they would more likely experience heat intolerance due to increased metabolic activity. Choice C reason: Restlessness is a symptom of hyperthyroidism, which can occur if a client is taking too much levothyroxine. Excess thyroid hormone can lead to increased nervous system activity, causing symptoms such as restlessness, anxiety, and tremors. Choice D reason: Decreased appetite is more commonly associated with hypothyroidism. In contrast, hyperthyroidism, which can result from taking too much levothyroxine, often leads to an increased appetite.
