The family member of a patient asks if vitamin C will prevent aging. In formulating an appropriate response, the nurse considers the:
a. Free radical theory
b. Immunity theory
c. Clinker theory
d. Continuity theory
ANS: A
The free radical theory posits that aging is a result of random damage from free radicals. Research is ongoing on the ability of substances with antioxidant effects to counter the actions of free radicals. Vitamins such a Vitamin C are thought to have antioxidant features and act as a free radical scavenger. The immunity theory posits that the cells of the immune system become progressively more diversified with age and lose self-regulatory ability. The use of vitamin C is not associated with this theory. There is no such theory as the clinker theory. The continuity theory is a sociological theory that deals with the tendency of individuals to develop and maintain consistent patterns of behavior throughout their lives.
