Q

what are the hormones of the pancreas (2)?

A

glucagon: made by the alpha cells in the islets of langerhans, increases bgl
insulin: made by beta, lowers BGL
somatostatin: inhibits the secretion of pancreatic hormones/enzymes*

Q

type 2 diabetes

A
  • later onset, caused by partial destruction of the iselt cells–>-response to insulin. there is some genetic predisposition (90% of kidswill develop if their parent shave)

Q

Tx for hypoglycemia?

A

1) food/drink if tolerated
2) glucagon paste ( if mild presentation)
3) glucagon or dextrose

17
Q

glucagon indications and conditions….

A

indications: suspected hypoglycemia
Conditions:
age:n/a (>4 yrs for IN powder)
LOA: alt
other: hypoglycemic

18
Q

contraindications for glucagon?

A

allergy or sensitivity/ phenochromocytoma

19
Q

glucagon Tx for pt who weighs less than 25kg?

A

weight=<25kg
route: im
dose: 0.5 mg
max singl dose: 0.5 mg
dose int: 20 mins
max # doses: 2

20
Q

Glucagon TX for a pt who weighs more than 25 kg?

A

weigh:>25kg
route: IM
dose: 1mg
max sing dose:1mg
Dose int:20mins
Max #:2

21
Q

if the pt responds to the glucagon what els can we do for them?

A
  • give them glucagon paste/food/juice
22
Q

if the pt wants to refuse transport we must…

A

get a final set of vitals including BGL and get pt to sign a refusal , and document everything!

23
Q

how old dose the patient have to be for IN powder glucagon?

A

older or equal to age 4

24
Q

what are some considerations for treat and discharge?

A

pt = >18AND <65
pt=diagnosed w diabetes
-hypoglycemia can be explained by insulin admin/oral intake
-pt responded in a single dose ofglucose admin(any form)
- single episode iin 24 hrs
- pt returned to normal loa + asymptomatic
- complete set of vital WNL
- not intentional OD
-hypoglycemia unrelated to alc/drug withdrawl
-no seizure activity
-not an oral hypoglycemic
- pt not ptregnant
-hypoglycemia considered not to be an acute medical illness

25
what must aso be met inoder to discharge a pt?
- pt has acess to adequate food, resonabile adult agress o stay w pt for next 4 hrs, all sdm questions=answered, the pt/sdm has been advised to follow up w their dr -instructed to call 911 if they need to - they have the ability to call 911 -pt/sdm has consent to discharge
26
treatment for IN powder glucagon...
age >4 route IN dose=3mg, max=3mg dose int:20 mins max #=2
27
what is insulinoma?
-rare neurodendocrine turmor that affects the pancreatic islets too ake excess insulin. -90% benign, s/: episodic hypoglycemia, CNS dysfunciton tx: surgically remove
28
29
Hyperglycemia issues can be caused by...
chronic cell resistance to insulin-->HHNS(typ2) or pt is not taking meds
30
what is the presentation of DKA?
CBG of 33mmol/l+, polyuria/dipsipa/phagia, dehydration, general weakness, lethargy, alt loa, n/v/, pain , nocturia, fruity breath, kussmals resp
31
how to manage hyperglycemia?
- IV established give fluid to replace water and electrolytes, bolus very slowly to prevent hydrocephalus
32
what are some common insulins?
lispro/humalog: very fast act (2-3hrs) regular/fast act:(2-5 hrs)peak (5-8hrs) intermediate act: extended insulin/zince suspension: peak (4-12hrs)(16-24hrs) long act: extendedzinc release peak (16-18)(>32hrs)
33
how does metformin work?
acts on cells making them less sensitive to glucose. if hypoglycemia caused by metformin=transport!
34
diabetes inspipidus:
ADH insufficency/kidney resistance to adh causing dehydration and lots of diluted pee.
35
s/s and managementof insipidius...
severe dehydration, hypernatremia, fever, CV collapse, death management: look for dehydration/hypotension & treat w NaCl prn
36
common diseased of the adrenals...
addisons: insufficent adh +cortisol cushings: too much cortisol and adh
