Question 1 of 35 :
A nurse is preparing to administer propranolol 2 mg by intermittent IV bolus over 15 min. Available is propranolol 2 mg in 50 mL dextrose 5% in water. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 200
Total volume to be infused = 50 mL.
Infusion time in minutes = 15 min.
- Convert the infusion time from minutes to hours.
Infusion time in hours = 15 min / 60 min/hr
= 0.25 hr.
- Calculate the infusion rate in mL per hour.
Infusion rate (mL/hr) = Total volume (mL) / Infusion time (hr)
= 50 mL / 0.25 hr
= 200 mL/hr.
