Which assessment finding of a postmenopausal woman necessitates a referral by the nurse to a healthcare provider for evaluation of thyroid functioning?

A. Slow weight loss: Weight changes can occur due to many reasons but are not an immediate indicator of thyroid dysfunction. B. Muscle weakness: This could be related to thyroid dysfunction, but it is not as specific as cold sensitivity. C. Leg numbness: Numbness might be related to various conditions, but it is not directly related to thyroid dysfunction. D. Cold sensitivity: This is a classic sign of hypothyroidism, which can occur in postmenopausal women. A referral for thyroid testing is needed to rule out thyroid dysfunction.
