Calculate the gravity rate for gentamycin 100 mg/100ml with secondary tubing (20gtts/mL) over 60 minutes.

Given: Total volume to infuse: 100 mL Infusion time: 60 minutes Drop factor of tubing: 20 gtt/mL To find: Drip rate (gtt/min) Step 1: Calculate the total number of drops Total drops = Total volume x Drop factor Total drops = 100 mL x 20 gtt/mL = 2000 gtt Step 2: Calculate the drip rate Drip rate = Total drops / Infusion time in minutes Drip rate = 2000 gtt / 60 minutes = 33.33 gtt/min Step 3: Round to the nearest whole number 33 gtt/min.
