MULTIPLE CHOICE

1. How does a theory differ from a fact?

  1. A theory proves how different influences affect a particular phenomenon.
  2. A theory attempts to explain and give some logical order to observations.
  3. A theory is a collection of facts about a particular phenomenon.
  4. A theory shows a relationship among facts about a particular phenomenon.

ANS: B
A theory is an unproven concept that attempts to explain and give some logical order to observations. For a theory to become a fact, there must be reproducible evidence.

DIF: Cognitive Level: Comprehension REF: p. 27 OBJ: 1 TOP: Fact vs. Theory KEY: Nursing Process Step: N/A MSC: NCLEX: N/A

2. The biological theory of aging uses a genetic perspective and suggests that aging is a programmed process in which

  1. each person will age exactly like those in the previous generation
  2. a “biological clock” ticks off a predetermined number of cell divisions
  3. genetic traits can overcome environmental influences
  4. age-related physical changes are controlled only by genetic factors

ANS: B
The biological theory of programmed process suggests that there is a “biologic clock” set with a predetermined number of cell divisions that will occur before the introduction of the aging process.

3. The Gene Theory of aging suggests which of the following ?

  1. The presence of a “master gene” prolongs youth.
  2. Genes interact with each other to resist aging.
  3. Specific genes target specific body systems to initiate system deterioration.
  4. The activation of harmful genes initiates the aging process.

ANS: D
The Gene Theory suggests that there is an activation of harmful genes that initiates the aging process.

DIF: Cognitive Level: Application REF: p. 27 OBJ: 2 TOP: Gene Theory KEY: Nursing Process Step: N/A MSC: NCLEX: N/A

4. The theory that identifies an unstable molecule as the causative factor in aging is the _____ theory.

  1. free radical
  2. molecular
  3. neuroendocrine
  4. crosslink

ANS: A
The free radical theory identifies free radicals—unstable molecules—that will cause aging after accumulation in the body.

DIF: Cognitive Level: Knowledge REF: p. 28 OBJ: 2 TOP: Free Radical Theory KEY: Nursing Process Step: N/A MSC: NCLEX: N/A

5. A patient uses good health maintenance practices. What aging theory most accurately relates to the patient’s practices?

  1. Wear-and-tear
  2. Free radical
  3. Neuroendocrine
  4. Molecular

ANS: A
The wear-and-tear theory suggests that health maintenance practices will prevent wear and tear on the cells of the body and will delay the aging process.

DIF: Cognitive Level: Analysis REF: p. 28 OBJ: 2
TOP: Wear-and-Tear Theory KEY: Nursing Process Step: Assessment
MSC: NCLEX: Health Promotion and Maintenance: Prevention and Early Detection of Disease
