An Older Resident in a Senior Community Tells a Nurse

An older resident in a senior community tells a nurse: "I am really worried. I joined an exercise class, and I just learned everyone's name yesterday, and I cannot remember them all today. Am I developing Alzheimer's disease?" The best response by the nurse is:

A) "You should be concerned. It is very unusual to forget something that you just learned."
B) "There is no reason to be concerned. Short-term memory decreases with age."
C) "Don't worry, a decline in both short- and long-term memory is a normal part of getting older."
D) "Although it is normal to have some changes in memory, forgetting names is very unusual."
