Diabetic ketoacidosis (DKA) is:
hyperglycemia >300 mg/dL - breakdown of body fat for energy - acummulation of ketones in blood and urine. Rapid onset.
Hyperglycemic-hyperosmolar nonketotic syndrome (HHNS) is:
hyperglycemia >600 mg/dL. - dehydration - absence of ketosis. Onset in several days.
DKA & HHNS result from sever HYPERglycemia from:
NOT enough insulin (new onset DM, lack of comliance DM treatment) and INCREASE NEED for insulin (stress, illness, infection, surgery, trauma)
signs & symptoms for both:
3P's - CHANGE MENTAL STATUS - signs of DEHYDRATION - kussmaul respirations (rapid and deep) - fruity breath (DKA/met.acid) -nausea / abd.pain (DKA) - seizures and revers.palarysis (HHNS)
nursing intervention - insulin
administer IV regular insulin (75 to 150 decrease) monitor level hourly.
nur. intervention - potassium
monitor serum potassium level. With insulin potassium shift into cells. Monitor for hypokalemia.
COMPLICATIONS: Rapid onset of hypoglycemia lead to:
hypokalemia, cerebral edema, fluid volume excess.
COMPLICATIONS: Renal failure:
hourly output < 30ml/hr - monitor hydration and renal function (I & O, creatinite levels)
