Total drops for 500 mL at 15 gtt/mL?

Total drops for 500 mL at 15 gtt/mL?

• A. 5000 gtt
• B. 8000 gtt
• C. 6000 gtt
• D. 7500 gtt

Answer: (D)

Total drops come from multiplying the volume by the drop factor. The drop factor (gtt per mL) tells you how many drops make up 1 mL, so you multiply the volume in milliliters by that number. For 500 mL at 15 gtt/mL, multiply 500 by 15: 500 × 15 = 7,500 drops. So the total is 7,500 drops. Other totals would require different numbers for the drop factor or volume—for example, a drop factor of 10 gtt/mL with 500 mL would give 5,000 drops, while a drop factor around 16 gtt/mL would yield about 8,000 drops.
