If you were required to administer a one-liter bag of lactated Ringers solution to an animal over a four-hour period, using an IV tubing with a calibration of 10, how many drops per minute would this patient receive?
  1. 100 gtt/min
  2. 42 gtt/min
  3. 400 gtt / min
  4. 22 gtt/min
Explanation
Answer: B - 42 gtt/min would deliver one-liter of lactated Ringers solution to an animal over a four-hour period, using an IV tubing with a calibration of 10. You multiply volume (1,000) by calibration (10), and then divide by the number of minutes (240), for a result of 42.
