500 calories a day
29
When should restrictive, therapeutic diets be used in geriatric patients? When should they not?
- they should be avoided unless their clinical value is certain - this is because these sorts of diets often have reduced taste and geriatric patients may become malnourished
30
What are some ways to prevent undernutrition in geriatric patients?
- enhance the social aspect - provide adequate time - enhance comfort, taste, and appearance of food - address dental complaints - cater to patient's food preferences
31
What is functional incontinence?
a form of incontinence in which there is no physiologic problem with urination but there is a problem with ambulation that prevents the patient from reaching the bathroom in time
32
What is overflow incontinence?
incontinence that arises due to an obstruction and increasing amounts of residual volume after voiding
33
At what age do women and men become equally affected by urinary incontinence?
age 80

What other illnesses does urinary incontinence increase the risk for?
- cellulitis, pressure ulcers, and UTIs from being wet often - sleep deprivation and falls with fractions as incontinence makes patients get up in the middle of the night - sexual dysfunction - depression and social withdrawal
35
What are some age-related physiologic changes that increase the likelihood of urinary incontinence in geriatric populations?
- detrusor overactivity and decreased contractility - BPH - more urine output during the night - atrophic vaginitis and urethritis - decreased ability to postpone voiding - decreased bladder capacity
36
What is the most common type of urinary incontinence?
stress incontinence
37
What cause stress incontinence?
sphincter dysfunction due to a weakened pelvic floor

39
How is functional urinary incontinence best treated?
environmental modification
40

What sort of urinary incontinence is treated with an anticholinergic?
urge urinary incontinence
42
How is overflow urinary incontinence treated?

43
Which urinary incontinence is treated with an alpha-adrenergic inhibitor?
BPH-mediated overflow incontinence
44
What can happen if you give a patient with overflow incontinence an anticholinergic?
you may cause an acute urinary retention
45
Why does osteoporosis occur?
because the balance between bone formation and resorption begins to favor resorption
46
What is osteopenia?
a milder, precursor to osteoporosis
47
How do we define osteopenia and osteoporosis?

Cushing's disease
51
What are risk factors for osteoporosis?
- early menopause - being White or Asian - having a sedentary lifestyle - smoking/alcohol abuse - low body weight
52
What is delirium?
an acute, potentially reversible change in mental status, usually caused by an inciting condition
53
Delirium carries with it what risk for mortality?
increased risk of mortality for up to two years following discharge
54
What criteria are used to diagnose delirium?
the confusion assessment method (CAM)
55
What are the diagnostic criteria for delirium?
- acute change in mental status and fluctuating course - inattention - and disorganized thinking or altered level of consciousness
56
What factors are predispose one to an episode of delirium?
- advanced age - dementia - functional impairment of ADLs - medical comorbidity - male gender - sensory impairment
57
How should delirium be approached from a treatment standard?
- identify the underlying disease and address contributing factors - avoid complications by removing indwelling devices, prevent or treat constipation or urinary retention, and encourage proper sleep hygiene - review and optimize drug list - offer orienting stimuli and adequate socialization - mobilize the patient as soon as possible - ensure proper nutrition
58
What are social restraints?
things like a "sitter" or family member in the room with a patient 24/7 rather than physical bindings or pharmaceuticals
59
What kind of restraints should be used on patients with delirium if needed?
social restraints
60
How does dementia differ from delirium?
- the course of delirium is more fluctuating and acute than is seen in dementia - furthermore, a diagnosis of dementia requires both memory and functional impairment
61
What is the most common form of dementia?
Alzheimer's disease
62
What tests are available to screen for dementia?
- MMSE (easiest) - SLUMS - MoCA (hardest)
63
Before diagnosing dementia you must also do what?
rule out other causes of cognitive decline such as medications, infection, depression, etc.
64
Are ADLs or IADLs first to be lost during early dementia?
IADLs
65
What is most often the first ADL lost in the course of dementia?
hygiene
66
Which ADL is the most likely to initially warrant a home health aide?
bathing
67
What MMSE score indicates moderate dementia?
10-19
68
In what order are basic functions lost during dementia?
- IADLs before ADLs - hygiene before other ADLs - generally speaking: first learned as a child are the last to be lost
69
How is dementia treated pharmacologically?
- primarily with cholinesterase inhibitors (donepezil, rivastigmine, galantine) in the mild to moderate stages - NMDA receptor antagonist (memantine) for moderate to severe
70
How does depression differ from delirium and dementia?
depression manifests with more somatic complaints than memory and function complaints
71
What treatment options are available for geriatric patients with depression?
- psychotherapy (CBT, interpersonal or problem-solving) - SSRIs are preferred drug - ECT is available for major depression, those with a suicide risk or mania
72
Under what circumstances is ECT indicated for depression in the elderly? What are the contraindications?
- indicated for major depression, cases with a risk of suicide or instances of mania - contraindicated in those with increased ICP, pheochromocytoma, intracerebal hemorrhage, recent MI, etc.
73
What is the response rate for geriatric patients with depression receiving mono therapy?
- 40% improve within 6 weeks and another 15-25 after an additional 6 weeks - overall, a relatively strong resposne
74
What is the most common prescribing error when it comes to depression?
failure to increase the dose to the recommended level within the first two weeks of treatment
75
When you're treating a geriatric patient with depression and mono therapy fails, what other options should you consider?
- consider switching to a different drug class - add psychotherapy - consult a geriatric psychiatrist
76
Why do geriatric patients have a higher risk of pressure ulcer?
- local blood supply to skin decreases - epithelial layers flatten and thin with age - there is decreased amounts of subq fat - collagen fibers lose their elasticity - tolerance to hypoxia decreases
77
What are the four stages of pressure ulcers?
1) persistent erythema of intact skin, won't blanch 2) partial-thickness skin loss involving epidermis, dermis, or both 3) full-thickness skin loss involving damage or necrosis of subq tissue 4) full-thickness skin loss with extensive destruction to muscle, bone, or supporting structures
78
What is a deep tissue injury?
- an area of tissue that painful, firm, mushy, boggy, or warmer/cooler than adjacent tissue - little or no ulceration and no way to detect how deep it's going - the wound is typically dark
79
What is an unstageable pressure ulcer?
- one for which the depth of injury cannot be assessed due to the presence of a hard eschar or significant slough - stable (dry, adherent, intact, and without erythema) eschars should not be removed
80
What are the four major complications of pressure ulcers?
- sepsis localized infection, cellulitis, osteomyelitis - pain - depression
81
What is the mortality rate of those who develop a pressure ulcer?
60% in older persons within one year of hospital discharge
82
What are the intrinsic risk factors for developing a pressure ulcer?
- age - nutritional status - arteriolar blood pressure
83
What are extrinsic risk factors for developing a pressure ulcer?
- pressure, friction, or shear | - moisture (urinary or fecal incontinence)
84
What steps related to skin care should be taken to avoid pressure ulcers?
- daily systematic skin inspection and cleansing - reducing factors that promote dryness (increase humidity, apply moisturizer, reduce exposure to cold) - avoid massaging over bony prominences - reduce moisture from incontinence, perspiration, etc. - minimize friction and shear using proper repositioning, turning, etc.
85
What mechanical loading steps should be taken to avoid pressure ulcers?
- reposition at least every two hours - keep head of the bed at lowest elevation possible - use lifting devices to decrease friction and shear - remind patients in chairs to shift weight every 15 minutes - do not use doughnut seat cushions
86
Under what circumstances should doughnut seat cushions be used to prevent pressure ulcers?
they shouldn't; they're contraindicated because they may cause such ulcers
87
