Question

30 units Humulin R insulin in 300 mL of normal saline (NS) to infuse for 12 hours. (Round to the nearest tenth if applicable) a. How many units per hour will be infused? ________ b. How many milliliters per hour will be infused? ________

Answer 1

Part 1.

In 12 hours 30 units of Humulin R insulin in 300 mL is to be infused.

So, per hour =
`(30)/(12)= 2.5` units are to be infused.

Part 2.

Now 30 units Humulin R insulin in 300 mL of normal saline (NS).

So, 2.5 units will be in :
`(300*2.5)/(30)= 25` mL

Hence. 2.5 units Humulin R insulin in 25 mL of normal saline (NS).
