T2DM + ASCVD should be on

Answer 11

metformin with GLP1 and/or SGLT2i

Question 12

T2Dm and CKD should be on

Answer 12

metformin and SGLT2i. GLP1 if SGLT2i is not tolerated well

Question 13

If you need to add on insulin for T2DM, initate at

Answer 13

10IU/day or .1-.2IU/KG a day

longtime basal insulin

decrease hepatic glucose production, decrease intestinal absorption of glucose, improve insulin sensitivity

Question 17

eGFR needs to be ___ to use biguanides.

Answer 17

> 45
if 30-45, don’t start but if continued, reduce dose by 50%
<30-> contraindicated
