The healthcare provider prescribes heparin 1,400 units/hour intravenously (IV). The IV bag contains "Heparin 20,000 units in 250 mL dextrose 5% in water." How many mL/hr should the nurse program the infusion pump to deliver? (Enter numeric value only. If rounding is required, round to the nearest whole number.)

Here's how to calculate the volume (mL/hour) the nurse should program the infusion pump to deliver heparin: 1. We know: Heparin dose rate: 1,400 units/hour (given by healthcare provider) Heparin concentration in the IV bag: 20,000 units per 250 mL (given on the label) 2. We need to find: Volume delivery rate (mL/hour) 3. Calculation: To find the volume rate, we can divide the heparin dose rate (units/hour) by the heparin concentration (units/mL) Volume rate (mL/hour) = Heparin dose rate (units/hour) / Heparin concentration (units/mL) Plug in the values: Volume rate (mL/hour) = 1,400 units/hour / (20,000 units / 250 mL) Important note: We can rearrange the fraction with the concentration term because we are dividing by units/mL, which is equivalent to multiplying by mL/units. So, effectively, we are multiplying by the reciprocal of the concentration. Volume rate (mL/hour) = 1,400 units/hour x (250 mL / 20,000 units) Volume rate (mL/hour) = 17.5 mL/hour (round to nearest whole number) Therefore, the nurse should program the infusion pump to deliver 18 mL/hour.
