Question

Order: Heparin 17U/hr Dose on hand: Heparin 2500U in 500mL NS How many mL/hr does the nurse administer the heparin? Round to the nearest whole number.

Answer 1

To calculate the mL/hr of Heparin to administer, the nurse can use the formula: Dose = (Rate x Volume) / Concentration. In this case, the nurse should administer approximately 3 mL/hr of Heparin.

Step-by-step explanation:

To calculate the mL/hr of Heparin the nurse should administer, we can use the formula:

Dose = (Rate x Volume) / Concentration

First, let's convert the units:

17U/hr = 17 units per hour

Concentration of Heparin = 2500U in 500mL of Normal Saline Solution

Now, let's plug the values into the formula:

Dose = (17 units/hr x Volume) / (2500 units/500mL)

Cross multiply and solve for Volume:

Volume = (Dose x Concentration) / Rate

Volume = (17 units/hr x 500mL) / 2500 units

Volume = 3.4 mL/hr

Rounding to the nearest whole number, the nurse should administer approximately 3 mL/hr of Heparin.
