when mixing insulin’s?

Answer 14

draw up rapid/short acting insulin first, then immediate acting insulin, use immediately

Question 15

the insulin pump uses _______ acting insulin

Answer 15

rapid acting, others use regular insulin

Question 16

Oral hypoglycemics and anti-hyperglycemics:

sulfonylureas (glyburide)

Answer 16

increase secretion of insulin

Question 17

Oral hypoglycemics and anti-hyperglycemics:

YES

Question 19

Oral hypoglycemics and anti-hyperglycemics:

Answer 24

glucocorticoids

Question 25

beta blockers may mask..
