A fixed rate intravenous insulin infusion of ______ is recommended to treat diabetic ketoacidosis
0.1units/kg/hour
A large number of antidiabetic drugs walk into a bar…
Which drugs work by activating PPARs, affecting fatty acid storage
glitazones (eg pioglitazone)
A large number of antidiabetic drugs walk into a bar…
Which drugs work by binding to GLP-1 receptors, slowing gastric emptying, increasing insulin secretion, and reducing glucagon secretion?
glutides (eg liraglutide)
A large number of antidiabetic drugs walk into a bar…
Which drugs work by binding to K+ATP channels and increasing insulin secretion?
sulphonylureas, for example gliclazide
A large number of antidiabetic drugs walk into a bar…
Which drugs work by inhibiting SGLT2, preventing glucose reabsorption in the proximal convoluted tubule?
SGLT2i- eg emoagliflozin
A patient with type 2 diabetes wants to get preggers. What do you do with her medications?
If on metformin, stay on metformin
If taking other drugs (eg, gliclazide), then switch to insulin
Don’t forget folic acid 5mg!
A single episode of ‘severe’ hypoglycaemia (needing external assistance) will scupper your driving licence, true or false?
If you’re a non-commercial driver, probably not
If you’re a commercial driver, then yes it could well do
Accelerated retinopathy can occur in pregnancy if the mother has existing diabetes, true or false?
TRUE
Eye checks every 3 months
After a pregnancy with gestational diabetes, the risk of having diabetes 10 years later is 10%, true or false?
FALSE
50% (and more like 80% if obese)
After surgery or other stress, insulin release is increased/decreased?
decreased
All people with newly diagnosed diabetes should be assessed by a nutritionist, true or false?
TRUE
An old person with diabetes presents with dehydration and confusion. Blood glucose is 35mmol/L and urine dipstick shows no ketones. What recently started medications could have contributed to them developing this compliation?
Hyperglycaemic hyperosmolar syndrome often secondary to steroids or thiazide diuretics.
An old person with diabetes presents with dehydration and confusion. They were recently started on a steroid medication and thiazide diuretic. Blood glucose is 35mmol/L and urine dipstick shows no ketones. How do you treat them?
Hyperglycaemic hyperosmolar syndrome
Treat with IV normal saline and monitor blood glucose - it should fall
Once blood glucose stops falling with this method - give low-dose insulin until blood glucose is back to 4-7 mmol/L
Continuous infusion pumps release long-acting insulin, true or false?
FALSE
Release short-acting insulin, according to basal rate +/- boluses
Diabetes in a neonate is most likely to be T1D, true or false?
FALSE
Monogenic (eg, MODY) rather than type I
Diabetic ketoacidosis equally occurs in type 1 and type 2 diabetes, true or false?
FALSE!
Although type 2 diabetics can go into a non-ketotic hyperglycaemic coma due to dehydration and hypernatraemia/hyperuricaemia
Diabetic ketoacidosis is associated with hypo/hyoernatraemia
hypernatraemia
Does a patient with blood ketones of 2 mmol/L have DKA?
No - threshold is >3 mmol/L
DPP4 inhibitors are taken orally, true or false?
true
Gestational diabetes usually presents in which trimester?
third
Glitazones cause weight loss, true or false?
false- weight gain
GLP-1 agonists can be taken as tablets, true or false?
FALSE
All incretins are injectable only
HBA1c provides a measure of glucose control over what time frame
the past 2-3 months
How do DPP4 inhibitors work?
incretin pathway, although dependent on GLP-1 levels
