21
Q

Prolapse affects what?

A

Bladder morphology

22
Q

What is Benign Prostate Hyperplasia?

A

Enlarged prostate.
Affects bladder morphology.

23
Q

Sexual dysfunction usually caused by what?

A

Decreased hormone production.

24
Q

How does RA differ from OA?

A

Morning stiffness, bilateral.
Longer duration, more pain at rest.
Usually the smaller joints (fingers, toes, etc).
Systemic changes - fatigue, weight loss, fever, anemia.

25
Q

Avoid what intervention with RA? Why?

A

Mobs/manips of upper c-spine.
Transverse ligament weakens & facets erode.

26
Q

Common cancers in older adults

A

Leukemia
Hormonal (breast, prostate)
Digestive

27
Q

Common sign of cancer

A

Fatigue disproportional to activity

28
Q

After age 50, muscle MASS declines at a rate of ____

A

1-2% per yr

29
Q

After age 50, muscle STRENGTH declines at a rate of ____

A

4% per yr

30
Q

What is IMAT?

A

Increased adipose between & within muscles.
Decreased strength and power (limited contractilitiy).
Strength training will NOT help bc force production won’t improve as long as fat still there (need to lose fat instead).

31
Q

Which muscle fibers decrease faster?

A

Type 2 (force production, power)

32
Q

Which declines first: muscle mass or strength?

A

Strength

33
Q

Bone density decreases at a rate of ____ after menopause (age 50 for men)

A

1-2% per yr

34
Q

Kyphosis can result in…

A

Anterior wedging compression fx (can cause kyphosis or be caused by kyphosis).
Poor ventilation - hard to inflate when hunched over.
GI issues bc stuff is squished.

35
Q

Osteopenia/porosis T-scores

A

0 to -1 = NORMAL
-1 to -2.4 = osteopenia
-2.5 or lower = osteoporosis
-2.5 or lower plus fx = severe osteoporosis

36
Q

Why are hip fractures REALLY bad in older adults?

A

Often non-union, takes way longer to heal than joint replacement.
Nutrition issues, infections, complications of ORIF, adverse response to anesthesia/meds, pneumonia, DVTs

37
Q

What is the most important cardiopulm consideration?

A

Decreased HRmax - determines extent of exercise intensity.
Can still do 80% HRmax

38
Q

HTN meds considerations

A

Dose determined based on resting BP, not exercise BP. Activity may overwhelm meds.

39
Q

Increased blood vessel stiffness results in…

A

Increased BP
Decreased LV contractility
Decreased CO
Slow O2 perfusion to tissues = muscle burn lasts longer, requires longer rest/recovery

40
Q

Pneumonia

A

Most common infectious cause of death.
Often misdiagnosed or caught late.
Symptoms may present more as confusion, lethargy.

41
Q

Dysrhythmia best detected by…

A

Palpating pulse (not pulse ox!)

42
Q

Decreased rods/cones affects…

A

Night vision
Color discrimination
Peripheral/upper fields

43
Q

Normal DTRs in older adults

A

Usually 1+ instead of 2+
Due to slower N conduction (normal age related change)

44
Q

Common vision conditions

A

Presbyopia (inability to see near, need reading glasses)
Cataracts, glaucoma, macular degen

45
Q

Risk of CVA >55yo

A

Doubles every decade

46
Q

Most appropriate way to test for sensation

A

Sharp/dull discrimination (bc light touch decreased)

47
Q

Chronic pain types: nociceptive

A

activation of pain receptors

48
Q

Chronic pain types: neuropathic

A

pathology of central and/or peripheral nervous system

49
Q

Chronic pain types: mixed/unspecified

A

multiple sources of pain, often longer duration

50
Q

What is Cachexia?

A

excessive metabolic wasting, does not respond to exercise

51
Q

What is the leading cause of disability in older adults (that is NOT a normal age-related change)?

A

Chronic pain
