An adolescent is admitted to the intensive care unit with diabetic ketoacidosis. The nurse prepares a continuous insulin infusion of 100 units (U) regular insulin in 500 milligram normal saline
When documenting this medication, how many units of regular insulin will this patient receive per milligram of IV solution? A) 0.175 U/milligram
B) 0.2 U/milligram
C) 0.25 U/milligram
D) 0.5 U/milligram
B
Feedback:
The problem tells us there is 100 U/500 milligram. To determine how many units are in each milligram, divide both numbers by 500: 100 U ÷ 500/500 milligram÷ 500 = 0.2 U/1 milligram.
