symptomatic patients need or more positive results out of RBG, FBG and HbA1c. asymptomatic patients need or more.
diet education for management of diabetes: T2 = ❌ T1 = ❌
match the insulin to the correct box
match the type 2 diabetes medication to its action: ❌ - reduces hepatic glucose output and increases insulin sensitivity ❌ - stimulate insulin secretion but can cause weight gain and hypoglycaemia ❌ - inhibits breakdown of CHO and prevents glucose absorption by slowing carbohydrate digestion and increasing length of satiety ❌ - stimulate insulin production, enhances beta cells proliferation, reduces appetite, suppresses glucagon secretion, reduces hepatic glucose output, slows gastric emptying, and causes weight reduction ❌ - block reabsorption of glucose at the proximal tubules of the kidney to increase glucose excretion in urine
match the type of T2DM to the example GLP1 - ❌ SGLT2 - ❌ sulphonylureas - ❌

islet cell autoantibodies
anti-GAD
C-peptide

DKA definition: glucose is above 15 10 12 17( 15, 10, 12, 17 )mmol/L and ketones are above ++ + +++( ++, +, +++ ), venous bicarb is below 15 20 25 10( 15, 20, 25, 10 ) or pH is below 7.3 7.4 7.35 7.25( 7.3, 7.4, 7.35, 7.25 )
increased decreased( increased, decreased ) plasma glucose --> positive negative( positive, negative ) feedback on beta cells of the pancreas --> decreased increased( decreased, increased ) insulin production --> positive negative( positive, negative ) feedback on the liver, muscle and adipose tissue --> negative positive( negative, positive ) feedback on glycolysis, glycogenesis, lipogenesis and glucose transport --> decreased increased( decreased, increased ) plasma glucose --> negative positive( negative, positive ) feedback on beta cells of the pancreas
which of the following does not counteract the action of insulin?
glucagon
catecholamine
growth hormone
cortisol
oestrogen
insulin deficiency --> lipolysis --> increased free fatty acids --> ketone body production --> metabolic acidosis

infection
MI
stroke
trauma

lithium
clozaline
cocaine
beta blockers

IV fluids
IV insulin
VTE prophylaxis
potassium supplement
magnesium supplement
hypoglycaemia is blood glucose <mmol/L
30 10 20 5( 30, 10, 20, 5 )% of diabetics experience a hypoglycaemic coma once during their lives. 10 5 15 20( 10, 5, 15, 20 )% of type 1 diabetics suffer 1 episode of severe hypoglycaemia per year. 50 30 40 60( 50, 30, 40, 60 )% of type 1 patients have a blood glucose <3.5 on any one night.
