A client is receiving Phenylephrine IV at 160 mL/hr. It is available as Phenylephrine IV 300 mg in 500 mL D5W. What is the flow rate in mg/min? Round to the nearest tenths place where applicable and enter numeric value only (no commas or labels) ________ mg/min

Step 1 is to identify the available concentration of the medication Available concentration = Total mg ÷ Total mL Available concentration = 300 ÷ 500 300 ÷ 500 = 0.6 mg/mL Step 2 is to calculate the dosage delivered per hour mg per hour = mL/hr × mg/mL mg per hour = 160 × 0.6 160 × 0.6 = 96 mg/hr Step 3 is to calculate the dosage delivered per minute mg per minute = mg/hr ÷ 60 minutes mg per minute = 96 ÷ 60 96 ÷ 60 = 1.6 mg/min Step 4 is to round to the nearest tenth 1.6 = 1.6 Answer: 1.6
