1. A gerontological nurse is preparing a plan of care for an older adult applying
the error theory of aging as the foundation of the plan. Which concept would the
nurse integrate into the plan?
A. Perpetuation of DNA mutations results in organ and system malfunction.
B. Age -related dysfunction of organs and body systems results in DNA
mutations.
C. The number of cell divisions is genetically predetermined.
D. Errors in organ function contribute to changes in the cells' genetic code.

Answer: A

Rati onale: The error theory of aging proposes that genetic mutations are
perpetuated through the aging process, resulting in organ malfunction and
eventual decline in body function. Organ malfunction results from, but does not
cause, the genetic mutations in q uestion. A genetic predetermination of the
number of cell divisions is associated with the programmed theory of aging.

2. A nurse is explaining to an older adult client that many of the changes in his
body that are currently causing him frustration may have their origins in genetic
changes. The nurse also explains that these genetic changes may have benefited
him during his younger years. Which of the following theories of aging underlies
the nurse's explanation?
A. Disposable soma theory
B. Free radical theory
C. Mutation accumulation theory
D. Antagonistic pleiotropy theory

Answer: D

Rationale: Antagonistic pleiotropy theory proposes that genetic mutations that
are problematic in later life may be rooted in mutation that played a beneficial
role earlier in life. The disposable soma theory proposes that aging is related to
the use of the body's energy rather than to genetics. The free radical theory
suggests that aging is due to oxidative metabolism and the effects of free
radicals, highly unstable, reactive molecules containing an extra electrical charge
that are generated from oxygen metabolism. The mutation accumulation theory
suggests that aging occurs due to a declining force of natural selection with age.

3. An 80 -year -old female client explains to the nurse that she attributes her
