Lecture 14: AMS + Psych Emergencies Flashcards
Psych
() is slow in onset and chronic in nature
Dementia
() is an acute change in attention and mental functioning
Delirium
If a patient presents with neuro deficits and AMS, the first thing you focus on is…
their LOC
If you have an AMS patient that is also hypoxic, you should probably order a ()
ABG
The main restriction to using a simple mask or NRB over NC is (time)
NRB and simple mask can only be used for a few hrs.
There are 3 things you can administer IV for an AMS patient that are pretty much 0 risk. They are:
- Dextrose
- Thiamine
- Naloxone
But thiamine b4 dextrose if chronic ETOH
Psych
You have treated the pt’s vitals and started 2 large bore IVs. They are currently stable. Your next step is to…
Obtain history
Very abrupt onset of AMS is most likely () or () or seizures.
Ischemia or SAH
Associated symptoms in a neuro history
Have fun
GCS scale (better know this)
- EYES: spontaneous, verbal, pain, none
- VERBAL: oriented, confused, weird responses, weird SOUNDS, none
- Motor: Obeys, Goes towards pain, withdraws from pain, Decorticate, Decerebrate, None
Decorticate = protect the core
A neuro deficit usually suggests a () abnormality of the brain
Structural
What lab measure serum ketones?
Serum-beta-hydroxybutyrate
You suspect SAH but CT non-con was negative. Your next test is a ()
LP
Delirium generally occurs over ()
Hours-days
The two agents used for acutely agitated delirious patients are:
- Haldol PO/IM (monitor for EPS and QT prolongation)
- Ativan PO/IM/IV (monitor for resp depression)
Haldol is an antipsychotic. Ativan is a benzo
Same tx for dementia pts with dangerous behaviors
Prior to discharging someone you gave Narcan to, you should observe them for ()
1-1.5 hours!
Narcan has a shorter half-life than some opiates.
Also consult psych if it was accidental. Intentional OD = SI attempt
Hypoglycemia is < () in symptomatic children and < () in asymptomatic children
- < 45 if symptomatic
- < 35 if asymptomatic
Neonates with hypoglycemia get () over 3-5 minutes, whereas Infants and Older children get () over 3-5 minutes. Maintenance dosing is with ()
All dextrose %s
- Neonates: D10W
- Infants/older children = D25W
- Maintenance = D10W
Glucagon if no IV access
You’re older, so you need more sugar in your water
In adults, hypoglycemia is treated with (dextrose %) over 3-5 minutes and with a continuous infusion of (dextrose %)
- D50W for adults
- D10W for maintenance to keep > 100
Glucagon for no IV
D10W for maintenance in every age group!
() is used for hypoglycemia that is refractory and related to (diabetic drug) use
Octreotide to counter sulfonylurea usage
SC injection
T/F: You should remove insulin pumps if a patient is becoming hypoglycemic
False. Consult endo to lower tha basal rate.
Generally, the only people that need to be admitted for hypoglycemia are those on (drugs)
Sulfonylureas for serial glucose monitoring
Insulin has 5 main actions:
- () into cells
- () into cells
- () environment
- Inhibits the breakdown of ()
- Inhibits the breakdown of ()
- Glucose into cells
- K+ into cells
- Anabolic environment
- Inhibits fat breakdown
- Inhibits protein breakdown
DKA is more common in type (1/2) diabetics
Type 1!
The 6 Is of DKA are:
- Infection
- Infarction
- Insult (to the body)
- Infant (pregnancy)
- Indiscretion (lack of care)
- Insulin (absence
honestly wouldnt think she’d test on this
DKA
Of hyperglycemia, volume depletion, and acidosis, the first symptoms will be from…
Hyperglycemia
DKA
The diagnostic criteria:
- BG > () mg/dL
- Anion Gap > () to ()
- Bicarb < ()
- pH < () with moderate ketonuria or ketonemia
- BG > 250
- AG > 10-12
- Bicarb < 15
- pH < 7.3
