Answer and Explanation

The Correct Answer is ["20"]

Heparin infusion calculation:

Heparin dose ordered: 1000 units per hour
Heparin concentration: 25,000 units in 500 mL
Conversion: 1 mL = 500 units

Calculations:

Units per hour = 1000 units
Units per mL = 25,000 units / 500 mL = 50 units/mL
mL per hour = 1000 units / 50 units/mL = 20 mL/hr

Answer: The IV pump should be set to 20 mL/hr.

Explanation

Dopamine infusion calculation based on weight and concentration.

Dopamine dose ordered: 3 mcg/kg/min
Dopamine concentration: 600 mg in 1000 mL (or 600 mcg/mL)
Client's weight: 110 pounds (converted to kg: 110 lbs / 2.2 = 50 kg)

Calculations:

mcg/min = 3 mcg/kg/min × 50 kg = 150 mcg/min
mcg/hr = 150 mcg/min × 60 min/hr = 9000 mcg/hr
mL/hr = 150 mcg/min / 600 mcg/mL = 0.25 mL/hr

Answers:

mcg/min = 150 mcg/min
mcg/hr = 9000 mcg/hr
mL/hr = 0.25 mL/hr
