NUR2214 Module 2 Quiz Overview Exam
Questions With Correct Answers
Common |Biological |Theories |of |Aging |- |CORRECT |ANSWER✔✔-- |Free |Radical |Theory |
- |Cross |Linkage |Theory
- |Biological |Clock |Theory
- |Wear |and |Tear |Theory
The |Free |Radical |Theory |- |CORRECT |ANSWER✔✔-states |that |"free |radicals" |are |formed |from |
incomplete |molecule |formation |or |overexposure |to |harmful |substances. |This |leads |to |the |
destruction |of |healthy |DNA, |cells, |and |connective |tissues |reducing |function |and |viability. |As |an
|individual |ages, |"free |radicals" |destroy |healthy |cells |and |tissues |more |readily, |this |predisposes |
the |individual |to |various |diseases.
The |Cross-Linking |Theory |- |CORRECT |ANSWER✔✔-Also |referred |to |as |the |glycosylation |theory |
of |aging, |states |that |accumulation |of |cross-linked |proteins |damages |cells |and |tissues, |slowing |
down |bodily |processes |resulting |in |aging.
Free |Radical |- |CORRECT |ANSWER✔✔-Molecules |that |are |harmful |and |unstable |that |are |
produced |by |process |of |metabolism |or |exposure |to |harmful |substances |
Free |radical |spread |can |be |limited |by
-smoking |cessation
-limiting |sun |exposure
-limiting |UV |light |exposure
-Diet |management
, Antioxidants |- |CORRECT |ANSWER✔✔-- |neutralizes |free |radicals
- |can |be |found |in |food |elements |such |as |in |vitamins |and |various |fruits |and |vegetables
Diseases |often |seen |in |older |adults |that |can |be |caused |by |free |radicals |- |CORRECT |
ANSWER✔✔-- |cancers
- |diabetes
- |arthritis
- |atherosclerosis
Biological |Clock |Theory |- |CORRECT |ANSWER✔✔-The |theory |that |cell-reproduction |and |death |
of |cells |is |genetically |preprogrammed. |This |helps |determine |a |person's |life |span.
**Note |that |this |varies |from |person |to |person**
Name |some |manifestations |of |cell |division |loss |associated |with |aging |- |CORRECT |
ANSWER✔✔-- |Menopause
- |skin |changes |( |dryness, |wrinkles, |loss |of |
| elasticity
- |graying |of |the |hair
- |atrophy |of |organs
Wear |and |Tear |Theory |- |CORRECT |ANSWER✔✔-a |view |of |aging |as |a |process |by |which |the |
human |body |wears |out |because |of |the |passage |of |time |and |exposure |to |environmental |
stressors; |much |like |a |machine |would.
Factors |that |may |speed |up |the |process |of |"aging" |or |the |wear |and |tear |effect |on |the |human |
body |that |causes |damage |to |internal |organs, |hormones, |DNA, |tissues |and |cells, |skeletal |
structures |like |bones, |ligaments, |muscles, |spinal |structure, |and |cartilage. |- |CORRECT |
ANSWER✔✔-- |stressors
