General Aged Care Flashcards
(145 cards)
how might we assess an elderly patient’s mobility?
TUG- timed up and go
the 6 minute Walk Test
what is happening structurally as the bladder stores urine?
bladder relaxation and internal + external urinary sphincter contraction
what examinations would you perform in an elderly patient who presents with a fall?
• Neurological examination- assessing for balance, coordination, gait, peipheral neuropathy
• Joint examination
• Visual acuity
• Postural hypotension- take the blood pressure
• Examine injured limb
• Look for mobility aids, glasses
• Look for deformities like kyphosis or lordosis
• Romberg’s test looking for impaired proprioreception
Dynamic and static balance testing with physiotherapist
-examine their footwear!
MMSE/RUDAs
describe the two micturition stages (storage and voiding) and the nerve fibres associated with it
storage of urine- hypogastric nerve sympathetically innervates detruser muscle relaxation and internal urinary sphincter contraction (via noradrenaline acting on alpha 1 receptors at bladder neck, and at beta adrenoreceptors in detruser muscle). Sympathetic nerve fibres inhibit parasympathetic nerve stimulation. Uninhibited somatic fibres in pudendal nerve release AcH on nicotinic receptors causing contraction of the external urethral sphincter.
As the bladder fills, stretch receptors increase afferent firing rates and is perceived by the CNS system
voluntary voiding- inhibition of the pudendal somatic nerve fibres (as directed by CNS) cause relaxation of the external urinary sphincter.
Parasympathetic fibres from the pelvic nerve coordinate bladder contraction and internal urinary sphincter relaxation–> voiding
what are some rehabilitation goals for patients following a stroke?
How might we achieve them?
- prevent complications e.g. PE/malnutrition/pressure sores/contractures etc
- optimise mobility
- optimise PADLs
- home visit by OT
- Assess driving capacity
- management of communication deficits e.g. dysarthria, aphasia
- application for community services e.g. meals on wheels, cleaning services etc
- provide education and support for carers/family
Multimodal approach requiring various allied health staff including OT, speech pathologist, physio, social worker and nursing staff. We can use splinting and certain positioning to prevent contractures (nursing) etc, we can practice progressive resistance exercises + strengthening exercises (physio), we can practice functional tasks such as cooking and use compensatory techniques such as altered cutlery (OT), we can seek extra community support services (social worker) for example.
what are the 5 elements of dementia?
- cognitive impairment
- chronic condition
- acquired condition
- change from previous level
- impact on function
what does an occupational therapist do?
they can assess cognition, functional assessment (ADLs/PADLs/CADLs), home + environment assessment
what extrinsic factor for falls in the elderly must we exclude?
polypharmacy- warrants medication review
consider anti-depressants, benzodiazepines, anti-hypertensives, digoxin and opioid medications
what are some treatments for dementia?
No curative treatment available, management is rather supportive in nature.
Anti-cholinesterase medications such as donezepil, rivastigmine can be used in mild-moderate AD. Only provides very slight cognitive benefit.
Memantine, an NMDA r antagonist can be used in moderate-severe AD. Again, clinical efficacy is limited.
adjuvant medications for psychotic symptoms/depression/anxiety etc
hallmark features of lewy body dementia?
- visual hallucinations
- fluctuating course- can vary from day to day and can mimic delirium
- parkinsonian features
- late onset memory loss
what are some bad prognostic factors for rehabilitation after stroke?
- difficulty isolating any movement in affected limb
- receptive dysphasia
- visual neglect/hemianopia
- urinary + faecal incontinence
who benefits from a CGA?
elderly patients with moderate disability
what RUDAs score suggests possible cognitive impairment?
RUDAs score equal to or less than 22 out of 30
what is fried’s criteria for frailty?
1 unintentional weight loss 2 slow walking speed 3 weakness 4 exhaustion 5 low physical activity
greater than 3= frailty
what is senakot and its usual dosing?
senna (bowel stimulant) twice a day
list the hip precautions post THR?
No hip adduction across the midline
No hip flexion beyond 90 degrees
No internal rotation of the hip
Caution when squatting or sitting
no driving for 6 weeks
hip precautions generally for 3 months post op
what is the risk assessment component of a CGA?
screening for falls risk (FRAT tool)
screening for risk of pressure sores (skin integrity scale)
risk factors for dementia?
age education level genetics (think AD) head injury cerebrovascular disease- e.g. obesity/diabetes/HT depression
what assessment tools can we use to assess an elderly patient’s functional independence (e.g. ADLS/PADLs etc)?
FIM- functional independence measure
Barthel index
how might constipation cause urinary incontinence?
- weakened detrusor muscles due to straining
2. impacted rectum may compress the bladder- leading to the sensation that the bladder is full
what parts of the CNS are involved in the micturition reflex?
pons
PAG
spinal cord
what happens to the bladder during micturition?
external urinary sphincter relaxes
bladder (detruser muscles) contracts
ddx for dementia?
delirium, depression, mild/moderate intellectual disability, drugs
side effects of cholinesterase inhibitors
GI disturbances (N+V, anorexia), vivid dreams, low heart rate, dizziness
