A nurse is preparing to administer nitroglycerine 15 mcg/min by continuous IV infusion. Available is nitroglycerin 25 mg in 250 mL of dextrose 5% in water (D5W). The nurse should set the IV pump to deliver how many mL/hr? (Round to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.

Convert the dosage to mcg per hour: 15 mcg/min×60 min/hr=900 mcg/hr15 Convert the available nitroglycerin concentration to mcg/mL: 25 mg=25,000 mcg The concentration is(25,000 mcg/250 mL)=100 mcg Calculate the flow rate in mL per hour using the dosage and concentration: Flow rate (mL/hr)=(900 mcg/hr100 mcg/mL)=9 mL/hr
