DM Flashcards
DM1
lack of insulin
DM2
insulin resistance
DM1 Tx
(if you dont treat they will DIE)
- Diet (least imp)
- Insulin (most important)
- Exercise
DM2 Tx
(they are DOA)
- Diet (most imp)
- Oral hypoglycemic
- Activity
Primary Tx DM2
calorie restriction - divide meals into 6 feedings/day
S/S of DM
polyuria (pee a lot)
polydipsia (thirsty)
polyphagia (eat a lot/swallow)
Regular Insulin
clear solution, IV drip
- 1-2-4
NPH
intermediate insulin
- it is cloudy
- suspension—it precipitates—can’t give IV drip
- N = not so fast, not in the bag
- 6-8-10-12
Lispro (Humalog)
- give WITH the meal
- fastest
15: 30:3
Glargine (lantus)
- long-acting insulin
- no peak
- duration 12-24 hours
- only one you can give safely at bedtime
Expiration dates
- opening package invalidates manufactures date
- once open, exp. date is 30 days after
Excercise
- exercise potentiates insulin action
- like another shot of insulin
Sick days
serum glucose goes UP
need insulin even when eating
sips of water
- two problems: hyperglycemia and dehydration
hypoglycemia causes
not enough food
too much insulin
too much exercise
s/s of hypogylcemia
think drunk pt in shock - staggering gait - slurred speech - cerebral impairment (labile) - slow reaction time - decrease social inhibition shock - tachycardia, tachypnea, low bp - cold/clammy mottled skin
treatment of hypoglycemia
- give pt sugars/ juice/ soda
- sugar + starch or protein
causes of DKA
- too much food
- not enough insulin
- not enough exercise
- acute viral upper respiratory infection within last 2 weeks #1 cause
s/s of DKA
Dehydration
Ketones in serum, Kussmals, High K+
Acidosis, Acetone breath, Anorexia r/t NV
Treatment of DKA
Regular insulin IV
IV fluid 200ml/hr
DKA
high glucose in type 1
HHNK or HHS or HHNS
high BS in type 2
- don’t burn ketones, no acid
- think DEHYDRATION
1 Tx for HHNK
rehydration
higher priority? dka or hhnk?
HHNK–> DKA easily responds to insulin
