A patient is prescribed to receive 1.2 liters of intravenous (IV) fluids over an 8-hour period. What is the infusion rate in milliliters per hour (mL/hr)?
- A200 mL/hr
- B250 mL/hr
- C100 mL/hr
- D150 mL/hr
Show answer & explanationAnswer & explanation
Correct answer: D. 150 mL/hr
To find the infusion rate in mL/hr, first convert liters to milliliters and then divide by the total hours. 1.2 liters is equal to 1200 milliliters. Dividing 1200 mL by 8 hours gives 150 mL/hr.
Why the other options are wrong
- A. This rate is too fast; it would deliver 1.6 liters over 8 hours.
- B. This rate is significantly too fast; it would deliver 2.0 liters over 8 hours.
- C. This rate is too slow; it would deliver only 0.8 liters over 8 hours.
IV Infusion Rate Calculation
Calculating the rate at which intravenous fluids are administered, typically in milliliters per hour (mL/hr).
- Requires converting volume units if necessary (L to mL).
- Involves dividing total volume by total time.
- Essential for patient safety and medication delivery.
Memory trick: Volume over Time gives Rate, remember to Convert!
