Q

physiologic theory of aging: error theory

A

as a cell ages, proteins contain more and more errors and eventually a “killer” gene is produced

the more a cell ages and copies, will not work as well as before and more errors accumulate

suggests that errors create a killer gene

Q

physiologic theory of aging: free-radical theory

A

free-radicals are unpaired electrons (circulate as super-oxide O3 and peroxide H2O2 and hydroxyl free radical)

  • three forms of oxygen that are highly reactive or volatile
  • aka, reactive oxygen species
  • forms of oxygen with a loose electron (O2 is stable, but O3 is not. H0 is stable, H2O2 is not, etc.)

unpaired electrons are produced both intrinsically and externally -> altered biochemical reactions thus result in DNA damage and cell death

Q

physiologic theory of aging: stress-adaptation

A

age-related physical changes lead to a decrease in the ability to cope with stressors

related to hypothermia (metabolism slows down, and heat is a byproduct of metabolism), cardiac output decline, and vital capacity result in diminished ability to cope with stress

high degree of variability, which could explain why some people live so much longer than others

4-10% of elderly Americans
27
types of elder abuse (5)
- physical - sexual - psychological/ emotional - financial - neglect
28
theories of elder abuse (4)
- cycles of learned violence (we know that people who are abused may be more likely to become abusive; e.g., abused child taking care of abusive parent) - caregiver stress (the greater the requirements on the caregiver, the greater risk this relationship could deteriorate) - pathophysiology of abuser (?) - physical/mental impairment of the elder (the more dependent the patient, the higher the risk)
29
suspicious indicators of elder abuse
- description of injury does not match physical findings - history of similar injuries - appears afraid or avoids eye contact - flinches when you touch them - bruises, burns scratches, lacerations in unusual places - injuries in various stages of healing - patterns of seeking different health care - frequent emergency room use - withdrawal from social activities - significant changes in affect - untreated malnutrition - misuse of medications - untreated medical needs

31
when injury occurs to an unrestrained patient in long-term care, lawsuits are typically the result of.....
failure to meet reasonable standards of care e.g., negligent in duty to provide care for a wandering patient or alarm systems not working NOT failure of the result to restrain (don't restrain when not needed!)
32
methods of decision making for patients who cannot communicate wishes: appointed person
appointed person makes decisions based upon their understanding of the patient's past wishes and values
33
methods of decision making for patients who cannot communicate wishes: rational approach
makes decisions based on what a "rational" person would do under the circumstances
34
Medicare wants providers to counsel whom about ACPs?
all folks 65yo and older
35
methods of decision making for patients who cannot communicate wishes: substituted judgement
attempts to determine what decision the patient would make if they were able
36
what is the single best method of decision making for patients who cannot communicate their wishes
advanced directives! durable statements of intent based upon the patient's last written wishes
37
a contract between the patient and HCP which specifies wishes for end-of-life care in terminal events
living will
38
a document that authorizes another person to make decisions regarding healthcare when the patient is no longer able to
durable power of attorney
39
are advanced directives legally binding?
no and not all states recognize advanced directives legally even states that do recognize them do so only when the patient is, in the opinion of the HCP, hopelessly and terminally ill

true
42
true or false: impaired judgement does not make a person incompetent?
true
43
true or false: living wills are generally only honored if a person is terminally ill
true
44
true or false: if a person is not declared incompetent, then they can give informed consent

48
true or false: the number of older men in the workforce has increased in recent years
false - percentage is decreasing, while percentage of women is increasing
49
which theory of aging suggests that vitamins might delay aging process?
free radical theory reactive oxygen species destroy bonds and ultimately kill cells in contrast, vitamin E is an example of an antioxidant that could theoretically neutralize free radicals and keep them from destroying cells
50
normal or pathophysiologic change in aging? increased A:P chest diameter
normal change of aging important to distinguish from COPD via typical history, symptoms, and diagnostic spirometry findings
51

normal or pathophysiologic change in aging? decreased skin turgot
normal change of aging important to distinguish from dehydration, can draw labs for BUN
53
(4) body systems MOST affected by the NORMAL changes of aging
- neurological - cardiovascular - musculoskeletal - lower urinary because of the weakness in those four organ systems, the strain of any illness tends to manifest in one of these four predominant cluster of symptoms tends to occur for any illness, e.g., confusion
54
predominant symptom cluster of illness in the older adult (5)
- acute confusion - depression - falls - incontinence - syncope when these occur, can mean anything e.g., if they have acute onset confusion check for UTI and pneumonia, MI, not suspecting a neurological event first
55
as a consequence of normal age-related declines in compensatory mechanisms, a new illness/ disease may present itself [earlier vs. later]
earlier! as a result, possibly easier to treat

58
3 (D)s that occur more commonly in elderly patients than younger adults

78
questions to ask after a fall
- what were you doing when you fell? - was there an aura? warning or prodrome that this was going to happen? - was there loss of vision? transient vision loss? - did you experience vertigo? - was there any loss of consciousness? - did you break the fall with a hand or other body part? - is this an isolated incident or are falls happening more often? - what medications are you taking? - do you ever drink alcohol?
79
(4) required components of physical exam after a fall

80
occurs when tissues are compressed or subject to pressure and vascular pressure is exceeded -> lose vascular supply aka ability to provide nutrition to and drain an area
pressure ulcer significant contributing factors include friction, shear forces, and nutritional deficiencies
81
contributing factors to pressure ulcers
- friction - shear forces - nutritional deficiencies - moisture - advanced age - low BP - smoking - elevated body temperature - dehydration all of these are things that contribute to decreased tissue perfusion or increased burden on the pressure externally
82
types of ulcers (6)
