Q

where is hypoglycemia more frequently seen?

A

in type 1 pts d/t insulin injections (PO insulin not used because it will be broken down by stomach enzymes due to it being a hormone and protein)

Q

hypoglycemia occurs if?

A
  • pt receives too much insulin
  • pt doesn’t eat enough (lack of CHO in diet)
  • pr overexerts themselves (body uses glucose as fuel during exercise, which can deplete these stores)

Q

what is the Tx for hypoglycemic coma?

A
  • Glucagon breaks down glycogen and releases glucose
  • -> Administer 1mg glucagon SC or IM
  • -> 20-50mL 50% glucose IV (eg. 50 g glucose in 100mL of water)

Q

why is DKA usually seen in Type 1 DM?

A

body isn’t producing enough insulin, which usually helps glucose enter cells to be used as fuel, body breaks down FA

Q

what are the 3 requirements for DKA?

A
  • must be hyperglycemia

  • metabolic acidosis (fixed acid)

Q

HHS

A
A state of elevated blood glucose (hyperglycemia), and a high concentration
of glucose (hyperosmolar)
17
Q

what is HHS caused by?

A
  • excessive CHO intake
  • increased IR:
    1) presence of insulin
    2) hyperglycemia
    3) lack of a hypoglycemic
    response
18
Q

what else happens in HHS?

A

hyperosmolarity and dehydration

19
Q

remember, ketoacidosis in HHS does …

A

NOT occur because insulin is present in Type 2 DM. this means that lipolysis does not occur, so there is no excess of ketones

20
Q

severe hypoglycemia in HHS leads to…

A

1) hyperosmolarity
2) cellular efflux (glucose flows out of blood and into filtrate causing increased OP in the filtrate, pulling in
more fluid)
3) polyuria and glucosuria\
4) fluid loss
5) dehydration
