Term
What does infection have to do with diabetes?
Definition
diabetics are more susceptible to infection because of a defect in mobilization of inflammatory cells and impairment of phagocytosis by neutrophils and monocytes

therefor…loss of sensation may delay detection

protein, helps with preventing edema

no albumin=pitting edema
Term
How does diabetic retinopathy occur?
Definition
occlusions in small blood vessels in retina, cause microanerurysms, capillary fluid leaks out, hardens or hemorrhages

If patient is alert enough to swallow, what would you implement for treatment of hypoglycemia?
Definition
if <70 begin treatment
if >70 investigate signs and symptoms (if monitoring equipment not available, begin treatment)

give 15 to 20 g of a simple card such as (4-6 oz fruit juice or regular soft drink)
avoid foods with fat, glucose gel tablets can also be used

recheck blood sugar every 15 min after treatment until >70 and give patient regular snack to prevent rebound hypoglycemia

check blood sugar again 45 after treatment
Term
What should be avoided when initiating treatment for hypoglycemia in a patient that is alert enough to swallow?
Definition
avoid large quantities of quick acting cards so that fluctuation to hyperglycemia does not occur
Term
If patient is NOT alert enough to swallow, what would you implement for treatment of hypoglycemia?

What would you administer for acute settings?
Definition
Administer 1 mg of glucagon IM or subcutaneously.
Side effect: Rebound hypoglycemia

Have patient ingest a complex carbohydrate after recovery. 

In acute care settings
20 to 50 mL of 50% dextrose IV push

this occurs when patient has little but enough circulation insulin that ketoacidosis does not occur, neurological manifestations occur because of increased serum osmolarity

common in patients 60 years and older with type 2

life threatening but less dangerous that DKA
