Question

The physician orders 1,500 mg of a medication to be given over 90 minutes. The available medication is 1,500 mg/250 mL. You will set the pump to deliver ______mL/hr. (round to the nearest whole number)

Answer 1

To find the correct infusion rate for the medication, you calculate the rate in mL/min and then convert it to mL/hr. Based on the given information, you will set the pump to deliver 167 mL/hr after rounding to the nearest whole number.

Step-by-step explanation:

To calculate the infusion rate in mL/hr for the medication prescribed, we need to use the information provided. We have a medication dosage of 1,500 mg that needs to be infused over 90 minutes, and the medication is available in a concentration of 1,500 mg per 250 mL.

First, let's calculate the rate in mL/min:

• Total volume of medication = 250 mL
• Time for infusion = 90 minutes
• Infusion rate (mL/min) = Total volume / Infusion time
• Infusion rate (mL/min) = 250 mL / 90 min ≈ 2.78 mL/min

To convert to mL/hr, we multiply by 60 (since there are 60 minutes in an hour):

• Infusion rate (mL/hr) = Infusion rate (mL/min) × 60
• Infusion rate (mL/hr) = 2.78 mL/min × 60 ≈ 166.67 mL/hr

Rounding to the nearest whole number gives us 167 mL/hr. Therefore, you will set the pump to deliver 167 mL/hr.
