After teaching a client who is recovering from a complete thyroidectomy, the nurse assesses the client's understanding. Which statement made by the client indicates a need for additional instruction?

Choice A rationale: A complete thyroidectomy removes the thyroid gland, which is responsible for producing calcitonin, a hormone that regulates calcium levels. While some clients may experience temporary hypocalcemia post-surgery due to parathyroid gland manipulation, long-term calcium replacement is not always required. The parathyroid glands, if left intact, regulate calcium homeostasis. Choice B rationale: A complete thyroidectomy necessitates lifelong thyroid hormone replacement therapy. Without the thyroid gland, the body cannot produce triiodothyronine (T3) and thyroxine (T4), which are essential for regulating metabolism, growth, and development. Failure to replace these hormones would lead to severe hypothyroidism. Choice C rationale: As the entire thyroid gland is removed, the body's natural source of thyroid hormones is gone. Therefore, the client will require daily exogenous thyroid hormone supplementation, such as levothyroxine, for the rest of their life to maintain metabolic function and prevent the symptoms of hypothyroidism. Choice D rationale: Postoperative pain management is a standard component of care following any surgical procedure, including a thyroidectomy. The client should be encouraged to report pain and receive appropriate medication to ensure comfort, promote healing, and facilitate early ambulation and recovery.
