Q

the two primary functions of insulin and an additional function

A

pulls glucose into the cell
facilitates glucose storage to glycogen

and it inhibits the breakdown of stored glucose from proteins and fats

Q

what triggers the onset of type one diabetes

A

usually a viral infection- triggers the persons immune system to start attacking the beta cells of the liver

Q

what are the signs and symptoms of Type one diabetes

A

3 Ps
Polyuria-
Polydipsia- (d/t dehydration state)
polyphagia-(caused from the cell malnourishment from not getting glucose)

Eventually will lead to DKA if left untreated

often subtle and go unnoticed for years. 
3 P's
polyuria
polydipsia
polyphagia

also infection including vaginal and yeast infections., prolonged wound healing(d/t hyperglycemia effect on WBC, visual changes, and fatigue

Q

what is the normal glucose range

A

70-110

but in a diabetic pt we are looking for glucose control from 70-130

Q

what are the hormones that oppose the effects of insulin

A

glucagon- hormone that breaks down glycogen to glucose
epinephrine- causes vasospasm which maintains BP
growth hormone- promotes cell division and protein synthesis
coristol-suppressess immune system- increases blood sugar

Q

what are the symptoms of hypoglycemia

A
cold
clammy
sweaty 
pale
hungry
tachy

anxious

changes in LOC
Seizures

Q

what can be the cause of hypoglycemia

A

Alcohol- it inhibits glycogenolysis
not eating enough food
drinking without eating
too much diabetic medication
too much exercise without compensation of food.
a hyperglycemic pts blood glucose dropping too quickly

Q

what do you want to avoid when trying to correct hypoglycemia

A

don’t give CHO with fats because the fats slow down he digestion.

Q

what do you want to give a pt who is suffering from hypoglycemia

A

a simple CHO such as fruit juice or soda

and then recheck the blood glucose 15 minutes later

Q

what is treatment for diabetes

A
TIGHT GLUCOSE CONTROL
monitor Hbg A1c, blood glucose and renal panel
insulin replacement
diet and exercise
hospitalize
education
sick day treatment
monitor for s/s of hypoglycemia

Q

how does DKA develop

A

usually seen in type 1. the cells are starved for glucose so they kick start gluconeogenesis which synthesizes glucose from fat. the fat breaks down to glycogen and fatty acids. the glycogen breaks down to glucose and the fatty acids break down and as a by product releasing keytones.
the rising blood glucose results in osmotic diuresis increasing the loss of fluid and electrolytes which leads to hypovalemia and shock leading to renal failure causing retention of keytones and glucose. the rising keytones cause a decrease in the pH causing an acidic environment causing vomiting increasing the loss of electrolytes

17
Q

what can happen if DKA is untreated

A

extreme dehydration and electrolyte depletion and eventually death death

18
Q

how much fluid loss results from osmotic diuresis

A

6L

about 15% of total body water over 24 hours

19
Q

what are signs and symptoms of DKA

A
3 P's
polyuria, polydipsia, polyphagia
lethargy
dehydration
abd pain
anorexia
vomiting
tachy
hypotension (hypokalemia)
KUSSMAUL RESPIRATIONS
SWEET SMELLING BREATH
pH <7.30
20
Q

what lab findings are consistent with DKA

A
BG >250
arterial pH <7.30
Bicarb <15
keytones in blood and urine
electrolyte imbalance
high anion gap
21
Q

what are the priorties of Tx of diabetes

A

FLUID REPLACEMENT =#1
when glucose levels fall to 250 you may add glucose to prevent hypoglycemia
IV insulin REGULAR INSULIN ONLY- 50mg/dL/ hr
K+ replacement (initially K+ levels may be normal or high but once the fluid replacement and IV insulin- the insulin promotes K+ back into the cell causing hypokalemia)

22
Q

what do we need to monitor w/ DKA

A
LOC
vitals
labs
I&amp;O
Cardiac monitoring
s/s of cerebral edema (caused from hyponatremia)
23
Q

what is HHS

A

hyperosmolar hyperglycemic syndrome
found in pts who make enough insulin to prevent DKA but not enough to prevent severe hyperglycemia, osmotic diuresis and ECF depletion

24
Q

what are the signs and symptoms of HHS

A
few symptoms in the beginning
dehydration
hypotension
tachycardia
altered LOC
later signs:
glucose levels of 600-1200
little to no keytones in urine
electrolyte imbalances

dehydration leads to neurological symptoms
coma, seizure, hemiparesis and death

25
Q

what medications are used for diabetic nephropathy

A

Ace inhibitors and angiotensin II antagonists because

they control BP but also slow the progression of nephropathy

26
Q

what other eye complications can come from diabetes besides retinopathy

A

glaucoma
cataracts
retinal detachment

27
Q

what should BP , LDL, HDL and triglyceride levels be in a diabetci

A

BP-<130/80
LDL- < 100
HDL- >40
triglycerides <150
