diabetes Flashcards
type 1
no insulin
type 2
decreased insulin production.
tissue may be resistant to insulin or both.
when energy needs aren’t meet increased hungry, body starvation
polyphagia
kidneys are unable to retain excessive glucose, resulting in??
glycosuria
HgbA1C
glucose binds w/ hemoglobin. higher % of glycosylated
2-3month period
somogyi effect
hypoglycemia around 2am w/ rebound hyperglycemia as body tries to compensate may require decreases in PM insulin.
ketoacidosis DKA
> 300
ketones formed as by product of fat breakdown.
ketones are acidic, leading to metabolic acidosis.
DKA
kidneys try to compensate for acidosis by buffering.
as cells die without energy potassium is released into the bloodstream. then excreted by kidneys.
DKA symptoms
ketosis
metabolic acidosis
Kussmaul resp
ketone breath (fruity)
nausea abd pain
dehydration
when does potassium replacement begin?
voiding at least 25ml/hr
HHNS
severe dehydration due to polyuria. more gradual progression, later recognition due to partial insulin/glucose uptake by tissues.
HHNS symptoms
altered CNS
severe dehydration.
glucose >600
negative ketone urine
ph >7.4
^ serum potassium
Normal Saline for
shock or severe hypotension: 1/2 normal saline otherwise
hypoglycemia symptoms
nervousness
pallor
tremors
palpitations
sweating
hunger
weakness
dizzy
HA
drowsiness
irritability
loss of coordination
seizures
coma
