A community health nurse provides an annual flu prevention workshop at a local senior center
The activities include a lecture on preventing infections, which includes hand washing and limit-ing exposure to individuals who are ill, as well as an influenza immunization clinic. The nurse is basing her activities on what theory of aging?
a. Wear and tear
b. Oxidative stress
c. Autoimmune
d. Free radical
ANS: C
The autoimmune theory of aging describes changes in cells of the immune system, which make an older person more susceptible to infection. Prevention of infection is very important in older adults and can be accomplished by education and immunization. Wear and tear, oxidative stress, and free radical are incorrect because none of these theories of aging deal with prevention of in-fection.
