Answer to Question 1

B, C, D
Several age-related changes to the immune system occur, including decreased number of T sup-pressor cells, atrophy of the thymic cortex, and increased numbers of antibodies to self-antigens. The numbers of lymphocytes and B cells do not change.

Answer to Question 2

C
The Institute of Medicine (IOM) estimates that 1.5 million ADEs and 7000 deaths occur in the United States each year secondary to medication errors. Older adults are disproportionately af-fected; more than half of the medication errors occur in long-term care facilities and more than 500,000 occur among ambulatory Medicare patients. Some references use the 6 rights of medica-tion administration.
