lesson 2 Flashcards
(26 cards)
DKA
type 1 diabetic emergency
water moves for intracellular space to intravascular space (no edema)
polyuria (reduce vessel pressure) pees out electrolytes (might be useful to put on cardiac monitor since heart electrolytes are also getting peed out K,NA,Ca)
involve ketones
hyperglycaemia is BGL greater then ___
10mmol/L
body ph homeostasis
7.35
ketones are an…
acid
dehydration test
eyelid
skin pinch
thirsty? peeing?
look in mouth
DKA mortality rate
6.2%
what’s more common DKA or HHNK
DKA!
BP for someone with DKA
usually on the higher end
when do ketones build up?
DKA
when there is insufficient insulin to fuel body cells
someone with type 1 diabetes will have ____ levels of ketones
increased
what’s the results of DKA
increased release of glucose
decreased use of glucose
increased BGL
what conditions can occur from DKA
ketone formation
osmotic diuresis
dehydration
electrolyte abnormalities
DKA causes
missed insulin injections
stress
DKA onset
4-6 hours
HHNK
occurs in type 2 diabetics
same as DKA but some insulin produced by beta cells
- can result in a coma *
HHNK onset
days-weeks
3 P’s of hyperglycaemia
polyuria
polydipsia
polyphagia
what condition can have a higher BGL DKA or HHNK
HHNK
T/F DKA/HHNK are treated the same
T!
hyperglycaemia treatment
ensure airway is adequate BVM if needed
100% O2
IV fluids
cardiac rhythm
what does HHNK stand for?
Hyperosmolar Hyperglycemic Non-Ketoacidosis
what builds up when there is insufficient insulin
ketones (an acid)
HHNK onset
slow
3 P’s of hyperglycemia
polyphagia
polydipsia
polyuria
