restlessness, illusions, and incoherence of thought and speech.
Dementia Correct Answer-a slowly progressive decline in mental
abilities, including memory, thinking, and judgment, that is often
accompanied by personality changes
RASS Correct Answer-Richmond Agitation Sedation Scale
CAM ICU test Correct Answer--4 questions and a command
-Only tool validated for use on vent patients to diagnose delirium
Risk factors for ICU delirium. 3 categories Correct Answer-1) acute
illness
2) age/chronic health problems
3) environmental/iatrogenic
Leading iatrogenic risk factors for delirium? Correct Answer-
psychoactive medications
Management of delirium Correct Answer-- mobilize early
- improve sleep cycle
,- no haldol or atypical antipsychotics to prevent dilirium, or is prolonged
QT, Torsades, or when taking meds that prolongs QT
-Use Precedex rather than benzos when require sedation
-Benzos and delirium in alcohol or benzo withdrawal
Transient Ischemic Attack (TIA) Correct Answer-- transient episode of
neurologic dysfunction caused by focal brain, spinal cord, or retinal
ischemia, without acute infarction
-highest risk for stroke after a TIA is within 48hr
-15% of TIA precede stroke
-early intervention of TIA reduce risk for stroke-80%
TIA common and uncommon causes. Correct Answer-common:
atherosclerosis of large vessels, cardioembolism and a-fib
uncommon: hypercoaguable states, aortic dissection, hyperlipidemia,
smoking, obesity and DM
ABCD2 Risk Stratification Score Correct Answer--used by clinicians to
determine risk of stroke in the first 7 days following a TIA
-5 parameters: age, BP, clinical features, duration of TIA, DM
-Score range 0-7
Management of TIA Correct Answer-Use ABCD score to determine risk
of CVA. If 3 or greater, should be admitted
-Age (>60)
, -Blood pressure (>140/90)
-Clinical symptoms
-Duration (>60 minutes)
-Diabetes
Treatment of TIA Correct Answer--tPA initiated if symptoms do not
resolve and r/o bleed
-prophylactic antiplatelet therapy (if TIA is NOT caridogenic); ASA,
ticlopidine (ticlid), clopidogrel (Plavix), dipyridamole
-cardiogenic TIA requires anticoagulation
-IV heparin and then warfarin longterm
-carotid endarterectomy indicated in pts with ant circulation TIA and
moderate-to-high grade carotid stenosis (70-90%)
-control BP, (treat 220/120 or map >110) with CCB Nicardipine; mixed
a1/b1,2 blocker Labetalol (it decreases PVR w/o significant decrease in
HR or CO
-serum cholesterol, glucose, afib, stop smoking, avoid excessive alcohol,
lose weight
Modifiable risk factors for stroke Correct Answer-*Hypertension-most
significant
Hypercholesterolemia
Atherosclerosis
Atrial fibrillation
Obesity
