Wk 10 pt 2: Older adult PE (incl. in 9%) Flashcards
Blood pressure:
1) With aging, ______ and __________________ increase, whereas __________ decreases (widening pulse pressure)
2) Isolated systolic hypertension (SBP ≥140 mmHg with DBP <90 mmHg) after age 50 and widened pulse pressure >60 increases risk for what 3 things?
1) SBP and peripheral vascular resistance; DBP
2) Stroke, renal failure, and heart disease
1) Define orthostatic hypotension
2) What % of older adults does it occur in?
3) List 4 symptoms
1) Drop in SBP of >20 mmHg or DBP of >10 mm Hg, increase of HR of 20 BPM, or dizziness within 3 minutes of standing
2) 20%
3) Lightheadedness, weakness, unsteadiness, and visual blurring
Heart rate and rhythm:
1) Resting HR is unchanged, but ___________________ declines, affecting response to exercise and physiologic stress.
2) Why?
3) What abt heart rhythm can change w age?
1) maximal heart rate
-Due to slowing of pacemaker cells in SA node and blunted β-adrenergic response (Beta blockers may also do this)
3) More likely to have abnormal heart rhythms
1) Does RR change w age?
2) What do age-related changes in temp. regulation lead to?
1) No; respiratory rate unchanged
2) Susceptibility to hypothermia
What is the “5th vital sign” in older adults?
Functional Status
1) Assessment of older adults places special emphasis on maintaining what 2 things?
2) Maintaining what is the primary focus?
1) Independence and optimal level of function
2) Functional status
1) A number of performance-based assessment instruments for functional status are available, such as what? What does this screening assess?
2) Patients should also undergo risk factor assessment for _______
1) 10-Minute Geriatric Screen; physical, cognitive, and psychosocial factors
2) falls
1) What happens to skin in old age?
2) What happens to nails?
3) What abt hair on the head and body?
1) Becomes fragile, loose, and transparent (hands/forearms); purple patches/macules called actinic (or senile) purpura are frequently seen
2) Lose luster, yellow, and thicken, especially toes
3) Loses pigment and hairline recedes; also, loss of hair occurs elsewhere (incl. trunk, pubic area, axillae and limbs, which is normal)
What happens to the eyes with old age?
Eyeballs recede into orbit, corneas lose luster, pupils become smaller, dry eyes are a common complaint, and presbyopia occurs in nearly everyone.
List the 2 types of macular degeneration.
Which is more common and less severe? Which is neovascular?
Two types:
1) Dry atrophic: more common, less severe
2) Wet exudative: neovascular
List 2 symptoms of macular degeneration
1) Poor central vision
2) Blindness
What is the leading cause of visual impairment?
Cataracts
List some of the multiple risk factors for cataracts
1) Cigarette smoking
2) High alcohol intake
3) Diabetes mellitus (DM)
4) Medications (e.g., steroids)
5) Trauma
1) Define glaucoma
2) What does it lead to?
1) Increased intraocular pressure
2) Optic nerve damage
1) Acuity of hearing diminishes with age, known as _______________.
2) Define this condition
1) presbycusis
2) Can’t catch upper tones of words while hearing lower ones, causing words to sound distorted
What changes happen to the mouth with old age? What can also often account for these?
Diminished salivary secretions (dry mouth) and decreased sense of taste occurs
-Medications and disease often account for this
What changes happen to the thorax and lungs w old age? Which has little effect on function?
1) Capacity for exercise decreases
2) Chest wall stiffens
3) Skeletal changes accentuate dorsal curve producing kyphosis, but resulting “barrel chest” has little effect on function
In older adults:
1) Systolic bruits heard in middle or upper portions of carotid arteries suggest what? From what?
2) What does having an S3 strongly suggest after age 40?
1) Partial arterial obstruction; atherosclerosis
2) Heart failure and dilatation of the left ventricle from CHF
1) S4 can be heard in healthy older people, but often suggests decreased ____________ and impaired _______________.
2) What may occur as a result?
1) ventricular compliance and impaired ventricular filling
2) LVH (left ventricular hypertrophy)
1) What aortic condition is common in older ppl?
2) Aortic sclerosis results from what? Does it impede blood flow?
3) What condition results when leaflets become calcified and immobile (which can cause outflow obstruction)?
1) Systolic aortic murmurs
2) Fibrosis and calcification; does not impede
3) Aortic stenosis
1) Aortic sclerosis and aortic stenosis increase risk of CV ________ and ___________
2) Mitral regurgitation usually occurs how much later aortic sclerosis? Can it become pathologic? Why/ why not?
1) morbidity and mortality
2) A decade later; may become pathologic as volume overload increases in the left ventricle
[Peripheral vasc]:
Diminished or absent pulse may indicate what?
Arterial occlusion
[Abd]:
Widened abdominal aorta and pulsatile mass is seen in what condition?
Abdominal aortic aneurysm (AAA)
1) In the aging female, breasts diminish in size as glandular tissue atrophies and is replaced by ______.
2) Ducts surrounding nipples become more palpable or less palpable? Explain.
1) fat
2) More palpable as firm, stringy strands
