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

Insulin is the harmone that regulate the blood glucose level.  The rate of infusion of insulin should 3 ml/hr.

Given here,

Number of units = 3 units

Milliliter per Units  = 100 ml

Number of mililiters in an hour = = ?

So, 100 ml of solution have 100 units, it means each ml has 1 unit of Insulin.

To get 3 units per hour,

Put the values,

Therefore, the rate of infusion of insulin should 3 ml/hr.

3ml/hr

Explanation:

Number of units = 3units

Units per milliter = 100 ml

Number of mililiters in an hour = "X"

Hence, Given that 100 ml of solution have 100 units, each ml has 1unit, (100/100)

Therefore, 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 = 1 * X

X = 3 / 1 = 3ml/hr

Therefore, the final answer is 3ml/hr.
