1
A physician orders 1000 ml of D5NS (dextrose 5% in water) for a child to be given at 100 mL/hr. Calculate the flow rate if the delivery system is 10 gtt/ml.
2
An IV mixture is labeled 225 mg/250 cc. The physician prescribes 3 mcg/kg/min for a 50-kg patient. What is the flow rate if a microdropper administration set is used?
3
A physician prescribes 100 mL of an IV fluid. If the patient is to receive 5 ml/10 min via a microdropper administration set, calculate the flow rate.
4
A physician orders isotonic sodium lactate 5 mL/kg body mass to be administered intravenously for a 164-lb patient with severe acidosis. The rate of flow is 15 drops/min, and the administration set is 20 gtt/mL. What is the running time?
5
A physician orders 75 ml of 5% protein hydrolysate, 25 ml of dextrose, and 20 ml of isotonic salt solution for a child, to be administered intravenously at the rate of 60 gtt/min via a microdropper administration set. What is the running time?
6
An IV of 600 ml was ordered to infuse in 3 hours using a 15 gtt/ml set. With 2 hours remaining, you discover only 200 mL is left in the bag. At what rate will you need to set the flow?
7
The doctor orders 125 mg of medication per hour. The label on the IV bag reads 5g/1000ml. The set delivers 15 gtts/ml. How many ml should infuse each hour? The current flow rate is 10 gtts/min. Is this correct? If not, what is the correct flow rate?
8
An IV was started at 9:00 a.m. with orders to infuse 600 ml over 7 hrs. At 12 noon the IV infiltrated with 400 ml left in the bag. At 1:00 p.m. the IV was restarted. The set calibration is 20 gtt/ml. Calculate the new flow rate to deliver the fluid on time.
