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?

A. “I may need calcium replacement after surgery.": After a complete thyroidectomy, there is a risk of damage to the parathyroid glands, which regulate calcium levels. Clients may require calcium supplementation if their parathyroid function is affected. B. “I need to take thyroid hormones for the rest of my life.": After a complete thyroidectomy, the client will require lifelong thyroid hormone replacement to maintain normal metabolic function, as the body no longer produces thyroid hormones. C. “After surgery, I won't need to take thyroid medication.": After a complete thyroidectomy, the client will definitely need thyroid hormone replacement for the rest of their life, as their body can no longer produce thyroid hormones naturally. D. “I can receive pain medication if I feel that I need it.": It is important for the nurse to ensure the client knows that pain management is available as needed after surgery to help with comfort and recovery.
