Question

A provider order is written for insulin at 3 units/hr; the premixed solution is composed of 50 units of insulin in 100 mL in normal saline. At which rate (mL/hr) should the infusion run?

Answer 1

6.6 mL/hr.

Explanation:

Here we have to use the rule of three.

If 50 units of insulin comprehend 100 mL, then 3 units how much mL would be:

`3units(110mL)/(50units)=6.6 mL`

This means that 3 units per hour, would be 6.6 mL per hour.

Therefore the answer is 6.6 mL/hr.

Answer 2

the rate should be 6ml/hr

Explanation:

if 100 ml of solution have 50 units each ml has 0.5 units, (50/100)

so in order to get 3 units in one hour the equation would be

number of units = units per mililiter * number of mililiters in an hour

3 = 0.5 * x

x= 3 / 0.5 = 6ml/hr
