IV Flow Rate Calculations
| Question | Answer |
|---|---|
| The healthcare provider prescribes 250 mL of LR to infuse over 1 hour. Using the formula method to calculate the infusion rate, you would set the infusion pump at ______ mL/hr. | 250 |
| The healthcare provider prescribes 500 mL of D5 1/2NS to infuse over 5 hours. Using the dimensional analysis method to calculate the infusion rate, you would set the infusion pump at mL/hr. | 100 |
| The healthcare provider prescribes 800 mL of D5 1/2NS to infuse over 8 hours. Using the ratio and proportion method to calculate the infusion rate, you would set the infusion pump at ____ mL/hr. | 100 |
| The healthcare provider prescribes 500 mL to infuse over 4 hours using a 20 drop/mL administration set. The IV is to be regulated to ______ drops/min (rounded to the nearest whole number). | 42 gtt |
| The patient is to receive 50 mL over 15 minutes using a 15 gtt/mL administration set. Using dimensional analysis, the nurse calculates that the IV drip has to be set for _____ gtts/min. | 50 gtt |
| A patient has 1,500 mL of IV fluid prescribed to be infused over 8 hours using a 10 gtt/mL administration set. The nurse uses dimensional analysis and calculates that the IV drip has to be set for gtts/min (rounded to the nearest whole number). | 31 gtt/min |
| 400 mL of LR at 125 mL/hr is prescribed to be administered using a 10 gtt/mL administration set. If the drop factor constant is 6, then the IV would be regulated to _____ gtt/min (rounded to the nearest whole number). | 21 gtt/min |
| The healthcare provider’s order is for 125 mL NS at 250 mL/hr to be administered using a 15 gtt administration set. If the drop factor constant is 4, then the drop rate is ______ gtts/min (rounded to the nearest whole number). | 63 gtt |
| If the original flow rate of a medication was 15 gtt/min, and the recalculated rate is now 10 gtts/minute, the percent variation is %. | 33% |
| nurse is infusing 1,000 mL of a solution over 10 hours using macrodrip tubing delivers 20 gtt/mL. 4 hrs, 500 mL solution remains. In order to deliver desired amount in scheduled time, nurse dimensional analysis to calculate flow rate as ______ gtt/min | 28 gtt |
| nurse is to infuse 1,000 mL of a solution over 4 hours. After 2 hours, 400 mL of the solution remains. The nurse recalculates the flow rate to 200 mL/hr and documents the percent variation as 10%. Which of the statements below are true? | The new flow rate is correct. The original flow rate needs adjusting. The percent variation documented is incorrect. |
