Term
Hypoglycemia treatment:
Definition
If conscious:
10-15 g carbohydrate
Glucose tablets or gel
4oz juice
If unconscious with iv access:
1\2 to 1 amp D50
Consider 5% or 10% dextrose in water infusion
If unconscious without iv access:
Give glucagon 0.5-1mg IM
Term
Osmolality
Definition
Normal range with explanation
Calculation
Definition
Definition: the measure of solute concentration; the number of osmoles per liter of solution (mOsm/L)
Range: 275-295 mOsm/L [<275=dilute. >295=dry]
Calculation:
(2xNa) + glucose/18 + BUN/2.8
Term
iv fluid tonicity & osmolality

Term
Action of insulin
Definition
Drives glucose,K & H2OO into cells
Regular: (iv) onset 5-10 min
(SQ) onset 30 min
Peak 1-3 hrs
Effects last 6-8 hrs
**if treating DKA & HHS replace volume 1st
Term
DM
Categories
Definition
Defect in insulin secretion, action or both. FBS >126mg/do A1C >6.5%
Type 1: beta cell destruction resulting in absolute insulin deficiency
Type 2: secretory defect; resistance resulting in relative insulin deficiency
Gestational: due to pregnancy
"Other": genetic, medication induced, virus

Term
Hgb A1C
What it does
Normal range
Limitations
Definition
Measure of glucose bound to hemoglobin
Estimates effectiveness of DM therapy
Norm 4-5% (non-diabetic)
@6-7% BG ave range 100-150mg/do
>7% indicates poorly controlled glucose levels
Limitations:
African Americans have greater glucagon
Unk if same cut-off points for children
Anemia skews results
Term
Metabolic syndrome
Prevalence
Diagnostic features
Definition
Est 25% of US population with 40% incidence at age >60
Any 2 of the following:
Trig>150mg/do
HDL< 40 in males, <50 in females
Bp >130 sys or >85 dia
FBG >100 or diagnosed type 2
Waist circumference >40in men, >35in women
Term
Cells of the pancreas
Definition
Alpha: glucagon stored in liver
Beta: insulin
Delta: somatostatin (regulates TSH)
Term
DKA patho
Definition
Stress. Dim insulin osmotic. Glyco
Infection. Incr. Gluc. Diuresis. Urea
Medications H2O loss. Dehyd.
Diet. Elyte
Imbal.
Term
DKA causes
Definition
DM type 1
Term
Hypoglycemia value in serum glucose
Importance
Precautions
Definition
<70mg/dL
Higher mortality
Increases SNS activity
Identify cause
CV symptoms appear first then nervous system symptoms
Beta blockers blunt signs and symptoms
Check glucose often with beta blockers
Term
Hypoglycemia causes
Definition
Too much insulin
N/V
Interrupted oral, TF or parenteral
Strenuous activity
Excessive ETOH
Adrenal insufficiency
Severe liver disease (alpha cells stim glucagon to release glucose from liver)
Pregnancy
Term
Hypoglycemia symptoms
Definition
CV (initial symptoms):
Palpitation
