Question 1 of 5

The client has a nitroprusside drip infusing at 0.3 mcg/kg/min. The concentration is 50 mg nitroprusside in 250 mL D5W. The client weighs 70 kg. What will the IV infusion rate be?

Correct Answer: 6.3 mL/hr

Rationale:
To calculate: 0.3 mcg/kg/min × 70 kg = 21 mcg/min. Concentration is 50 mg/250 mL = 200 mcg/mL. Rate = 21 mcg/min ÷ 200 mcg/mL = 0.105 mL/min × 60 min/hr = 6.3 mL/hr.
