What is considered hypoglycemia in the hospital?
80mg/dL
How is hypoglycemia treated?
with 15grams of a rapid acting carbohydrate ie: juice, milk, or glucose tablet
If the blood suger is less then 40mg/dL what should be given?
D50 or glucagon
What is D50?

What is diabetes mellitus?
a chronic disorder of impaired carbohydrate, protein, and lipid metabolism caused by a deficiency of insulin
What is type I diabetes mellitus?
is nearly absolute deficiency of insulin
-if insulin is not given fats are metabolized for energy causing ketonemia (acidosis)
What is type II DM?
a relative lack of insulin or resistance to the action of insulin (obesity is major risk factor)
-insulin is sufficient to stabilize fat and protein metabolism but not carbohydrate metabolism
What are some macrovascular complications of DM?

-hypertension
-cerebrovascular disease
-peripheral vascular disease
What are some microcascular complications of DM?
-retinopathy
-nephropathy
-neuropathy
Why is infection a concern for DM patients?
due to the poor circulation they have decreased healing abilities

-hyperglycemia
-weight loss (common in type 1)
-blurred vision
-slow wound healing
-vaginal infection
-weakness and paresthesias
-sign of inadequate circulation to the feet
-signs of accelerated atheroscerosis
What does exercise do to glucose levels?
lowers it
What may cause the need for extra insulin?
-Stress
-Surgery
-Infection
