Administer Dopamine at 10 mcg/kg/min. The pharmacy provides dopamine 800 mg in 250 mL of D5W. Your client weights 85.3 kg. How many mL/hr are you to set the infusion pump? (Round answer to nearest whole number)

Answer and Explanation

The Correct Answer is ["15","994"]

To calculate the infusion rate in mL/hr for administering dopamine at 10 mcg/kg/min for a client weighing 85.3 kg, you would first convert the weight to micrograms by multiplying by 1,000,000 (since there are 1,000,000 micrograms in a kilogram). This gives you 85,300,000 mcg. Then, you multiply this by the dosage rate, which is 10 mcg/kg/min, resulting in 853,000 mcg/min. Since the pharmacy provides dopamine 800 mg in 250 mL, you convert 800 mg to micrograms (800,000 mcg) to find out how many micrograms are in each mL. This is done by dividing 800,000 mcg by 250 mL, giving you 3200 mcg/mL. Finally, to find out the mL/hr, you divide the required micrograms per minute (853,000 mcg/min) by the concentration of the solution (3200 mcg/mL), which equals approximately 266.56 mL/min. To convert this to mL/hr, multiply by 60, resulting in approximately 15,994 mL/hr. Rounding to the nearest whole number, you would set the infusion pump to 15,994 mL/hr.

Explanation

To calculate the IV pump setting, first convert the patient's weight from pounds to kilograms, knowing that 1 kilogram equals 2.2 pounds. The patient weighs 195 pounds, which is approximately 88.64 kilograms (195 / 2.2). Next, calculate the total units of Heparin needed per hour by multiplying the patient's weight in kilograms by the dosage ordered: 20 units/kg/hr. So, 88.64 kg * 20 units/kg/hr equals 1,772.8 units/hr. Now, determine how many milliliters per hour this dosage requires. Since the premixed bag contains 25,000 units in 250 ml, there are 100 units per ml (25,000 units / 250 ml). Finally, divide the total units needed per hour by the concentration to find the volume needed per hour: 1,772.8 units/hr / 100 units/ml equals 17.728 ml/hr. Rounded to the nearest whole number, the IV pump should be set to 18 ml/hr.
