A nurse researcher would consider which causes of normal aging a potential topic for study?
Note: Credit will be given only if all correct choices and no incorrect choices are selected.
Standard Text: Select all that apply.
1. Defects in DNA repair
2. Alteration of cell proliferation
3. Progeria
4. Alteration of stem cell proliferation
5. Cell senescence
1,2,4,5
Rationale 1: It is possible that the inability to repair these defects results in tissue aging.
Rationale 2: If cells are no longer replacing at the "normal" rate, tissues will age.
Rationale 3: Progeria is an abnormal aging syndrome.
Rationale 4: If stem cell proliferation slows down, the tissues age.
Rationale 5: Senescence means getting older. As cells age, so do tissues.
