Physiological Integrity

An antibiotic in a 150 mL piggyback is to be infused over 30 minutes with a drop factor of 15 gg/ml. How many drops per minute will be infused?

Correct answer: 75 gtt/min. To calculate: x gtt/min = volume/time (in minutes) x drop factor. (x gtt/min = 150 mL ÷ 30 min X 15 gtt/min. x = 75 gtt/min)
