Question

The order reads: regular insulin 12 units per hour. Available is regular insulin 100 , units in \( 150 \mathrm{~mL} \) NS. The infusion pump should be programmed for \( \mathrm{mL} / \mathrm{hr} \) in

Answer 1

The calculation involves setting up a proportion to find the milliliters per hour rate for an infusion pump, based on the prescribed insulin units per hour and the concentration of insulin in the solution.

Step-by-step explanation:

The question involves a medical dosage calculation, which is a practical application of mathematics in the health field. To determine the correct infusion pump setting in milliliters per hour (mL/hr), you must use the concentration of the insulin solution provided. The order is for 12 units of regular insulin per hour, and you have a solution that contains 100 units of insulin in 150 mL of normal saline (NS). To find the infusion rate, set up a proportion where 100 units/150 mL = 12 units/X mL. Solving for X gives you the amount of the insulin solution that should be administered each hour to deliver 12 units of insulin.
