A client is to receive a continuous infusion of insulin for diabetic ketoacidosis. at 5 units per hour. The medication is mixed: 100 units of Insulin in 100 mL of IV fluid. At what rate should the nurse set the IV pump? (Use a preceding, zero if it applies. Do not use trailing zeros. Round to the nearest tenth)

Determine the concentration of the insulin solution: There are 100 units of insulin in 100 mL of IV fluid. Concentration = 100 units / 100 mL = 1 unit/mL Calculate the volume (in mL) needed per hour: The client needs 5 units per hour. Since the concentration is 1 unit/mL, this means the client needs 5 mL per hour. Set the IV pump: The IV pump should be set to infuse at 5 mL/hr.
