2. What will the nurse expect the health care provider’s order to be when starting an older adult patient on thyroid hormone replacement therapy?

ANS:  C

Tapering off is characteristic of discontinuation of medications and is not appropriate for this situation. Older adults generally need a lower medication dosage than younger patients.

Children are not particularly allergic to analgesics or anticonvulsants.
