What principle should the nurse remember when trying to distinguish aging from diseases?
a. It is difficult to tell the difference because both processes are believed to result from cell injury.
b. It is easy to tell normal processes from abnormal processes.
c. Disease, unlike aging, has a genetic com-ponent.
d. Aging is defined as exceeding life expec-tancy, but not maximal life span.
ANS: A
It is difficult to differentiate between aging and disease because both occur secondary to cellular aging. It is not easy to differentiate normal processes from abnormal because aging appears as a normal process. Disease and aging have a possible genetic component. Aging is a time-dependent loss of structure and function that proceeds slowly and in such small increments that it appears to be the result of the accumulation of small, imperceptible injuries. It is not a time period outside of life expectancy.
