Answer to Question 1

D
Feedback:
With normal aging, secretion of thyroid-stimulating hormones (TSH) and the serum concentration of thyroxine (T4) do not change, although there is a significant reduction in triiodothyronine (T3), which is believed to be a result of the reduced conversion of T4 to T3 . Overall, thyroid function remains adequate.

Answer to Question 2

C
Feedback:
Although all the statements are true, the major factor increasing the risk of falls is a flawed response to changes in balance.
