Question

It is 3:00 am and the Pharmacy is closed. You receive a telephone order for a Zantac Drip at 6.25mg/hr continuous infusion. Using 500ml0.9%NS and Zantac 50mg/2ml vials, answer the following questions. How many milliliters of Zantac would you need to prepare a 24 hour supply of this infusion?

Answer 1

To prepare a 24-hour supply of a Zantac infusion at a rate of 6.25mg/hr, using 50mg/2ml vials, 6ml of Zantac would be required.

Step-by-step explanation:

To calculate how many milliliters of Zantac would be needed for a 24-hour supply at a continuous infusion rate of 6.25mg/hr, we use the ordered medication concentration and the volume of the vials. Since we are given Zantac 50mg in 2ml vials, we first determine how much Zantac is prescribed for 24 hours.

24 hours × 6.25 mg/hr = 150 mg of Zantac needed for 24 hours.

Now, we find out how many milliliters of the 50mg/2ml concentration are required to achieve 150 mg total dosage:

(150 mg × 2ml) / 50 mg = 6ml of Zantac required.

Thus, you would need 6ml of Zantac to prepare a 24 hour supply of this infusion.
