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.)
The Correct Answer is ["200"]
To answer this question, we need to calculate the infusion rate of the IV pump. The formula for infusion rate is:
Infusion rate (mL/hr) = Volume (mL) / Time (hr)
We are given the volume of the solution, which is 50 mL, and the time of administration, which is 15 minutes or 0.25 hours. Plugging these values into the formula, we get:
Infusion rate (mL/hr) = 50 mL / 0.25 hr
Infusion rate (mL/hr) = 200 mL/hr
Therefore, the nurse should set the IV pump to deliver 200 mL/hr. This is the answer to the question.

Correct Answer is ["50"]
Explanation
To calculate the flow rate in drops per minute (gtt/min), you can use the formula:
Flow rate (gtt/min) = Volume (mL) × Drop factor (gtt/mL) ÷ Time (min)
Given:
Volume = 1000 mL
Drop factor = 12 gtt/mL
Time = 4 hours
Convert 4 hours to minutes:
4 hours × 60 minutes/hour = 240 minutes
Then
Flow rate (gtt/min) = 1000 mL × 12 gtt/mL ÷ 240 min
Flow rate (gtt/min) = 12000 gtt ÷ 240 min
Flow rate (gtt/min) = 50 gtt/min
Therefore, the nurse should regulate the flow rate to deliver 50 gtt/min.
Correct Answer is ["0.25"]
Explanation
To convert micrograms to milligrams, divide by 1000: 250 mcg / 1000 = 0.25 mg. Round to the nearest hundredth: 0.25 mg. Therefore, the nurse should administer 0.25 mg of filgrastim.
