Your 186 lb patient in vasodilatory shock has been ordered vasopressin at 0.03 units/min IV. The vasopressin is available as 20 units/100 mL. At what rate will you set the IV infusion pump?

Answer :

The calculation would be the rate at which the IV infusion pump should be set for the vasopressin infusion, we can use the following formula:

Rate (ml/hr) = (Ordered dose (units/min) * Volume in ml) / Concentration (units/ml)

In this case, Given that the vasopressin solution is available as 20 units/100 ml, the ordered dose is 0.03 units/min, the volume available is 100 ml, and the concentration of vasopressin is 20 units/100 ml.

Let's substitute these values into the formula:

Rate (ml/hr) = (0.03 units/min * 100 ml) / 20 units/100 ml

Simplifying the equation:

Rate (ml/hr) = 0.15 ml/hr

Therefore, you should set the IV infusion pump at a rate of 0.15 ml/hr for the vasopressin infusion.
