Question

A physician orders metronidazole 500mg in 100ml qid to infuse over 1 hour with an infusion set of 20gtt/ml. What is the drip rate?

Answer 1

To calculate the drip rate, you multiply the volume of the IV bag by the drop factor of the IV set and then divide by the infusion time in minutes. For a 100 mL IV bag with a drop factor of 20gtt/mL over 1 hour, the drip rate would be approximately 33.33 drops per minute.

Step-by-step explanation:

To calculate the drip rate for an infusion of metronidazole 500mg in 100ml to be infused over 1 hour with an infusion set calibrated to 20 drops per milliliter (20gtt/ml), we use the following formula:

Drip Rate = (Volume in mL x Drop Factor) / Time in minutes

Plugging the values into the formula:

Drip Rate = (100 mL x 20 gtt/mL) / 60 minutes

Drip Rate = 2000 gtt / 60 minutes

Drip Rate = 33.33 drops per minute (rounded to two decimal places).

This is the rate at which the IV should be set to ensure the patient receives the medication at the ordered rate.

Answer 2

To calculate the drip rate of metronidazole, use the formula: Drip Rate (gtt/min) = Volume (ml) x Drop Factor / Time (min). In this case, the drip rate is approximately 33.33 gtt/min.

Step-by-step explanation:

To calculate the drip rate of metronidazole, we can use the formula: Drip Rate (gtt/min) = Volume (ml) x Drop Factor / Time (min)

In this case, the volume is 100ml, the drop factor is 20gtt/ml, and the time is 60 minutes since the medication is to be infused over 1 hour.

Plugging in these values, we get: Drip Rate (gtt/min) = 100 ml x 20 gtt/ml / 60 min = 33.33 gtt/min

Therefore, the drip rate for the metronidazole infusion is approximately 33.33 gtt/min.
