If a 60 gtts/ml set is being administered at 20 gtts/min for 30 minutes, how many milliliters are delivered?

  1. 600 ml

  2. 10 ml

  3. 300 ml

  4. 200 ml

The correct answer is: 10 ml

To find out how many milliliters are delivered in this scenario, we first need to understand the relationship between the drip rate, the drip factor, and the time of infusion. We know that the infusion is set at a rate of 20 drops (gtts) per minute with a drip factor of 60 gtts/ml. To determine how many milliliters are delivered over the 30 minutes, first, we need to calculate the total number of drops infused during that time: Total drops = Drip rate (gtts/min) × Time (min) Total drops = 20 gtts/min × 30 min = 600 gtts Next, we can convert drops to milliliters using the drip factor. The drip factor tells us how many drops makes up one milliliter. Now, we use the following conversion: Milliliters delivered = Total drops ÷ Drip factor (gtts/ml) Milliliters delivered = 600 gtts ÷ 60 gtts/ml = 10 ml Thus, the calculation shows that the total volume delivered is indeed 10 milliliters.
