The pharmacy delivers an IV infusion of sodium chloride 100 mL with regular insulin 50 units for a client in diabetic ketoacidosis. The prescription rate is 10 units/hour. How many mL/hour should the nurse program the infusion pump? (Enter numeric value only.)

First, we need to find out how many mL of the solution contains 10 units of insulin, which is the prescribed rate per hour. Given: The solution contains 50 units of insulin in 100 mL. The prescription rate is 10 units/hour. We can set up the proportion as follows: 10 units​/ x mL = 50 units​/100 mL Solving for x gives us the volume in mL that contains 10 units of insulin. Cross-multiplying and solving for x: X = 10 units×100 mL​/50 units After performing the calculation, we find that x equals 20 mL. So, the nurse should program the infusion pump to deliver 20 mL/hr. This is because 20 mL of the solution contains the prescribed 10 units of insulin.
