Order: Infuse Nitroprusside IV at 4 mL/hr. The solution available is Nitroprusside IV 50 mg in 100 mL D5W. Determine the flow rates listed below. Round to the nearest tenths place where applicable .Enter numeric value only (no commas or labels) ________ mcg/hr

Step 1 is to calculate the concentration of the solution in mg/mL mg per mL = Total mg ÷ Total mL 50 ÷ 100 = 0.5 mg/mL Step 2 is to calculate the milligrams delivered per hour mg per hour = mL/hr × mg/mL 4 × 0.5 = 2 mg/hr Step 3 is to convert milligrams per hour to micrograms per hour mcg per hour = mg/hr × 1000 2 × 1000 = 2000 mcg/hr Step 4 is to calculate the micrograms delivered per minute mcg per minute = mcg/hr ÷ 60 minutes 2000 ÷ 60 = 33.333... mcg/min Step 5 is to round to the nearest tenth 2000 = 2000.0 33.333... = 33.3 Answer: 2000.0 mcg/hr
