A client is to receive a continuous infusion of IV Insulin at 6 units per hour. Pharmacy delivers the medication that has a concentration of 200 units of regular insulin in 250 mL of NSS. 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)

Identify the Desired Dose: The client needs 6 units of insulin per hour. Identify the Available Concentration: The solution has 200 units of insulin in 250 mL of NSS. Set up the Proportion: (Desired Dose / Available Concentration) = (Rate (mL/hr) / Volume (mL)) (6 units / 200 units) = (X mL / 250 mL) Solve for X (the Rate): Cross-multiply: 6 units x 250 mL = 200 units x X mL 1500 = 200X X = 1500 / 200 X = 7.5 mL/hr
