A primary healthcare provider prescribes 1.5 L of normal saline (NS) to be given over 24 hours for continuous intravenous (IV) infusion to a client who has diarrhea.
What should be the rate of infusion that is required to be set in the infusion pump?

A.

41.7 mL/hr

B.

83.3 mL/hr

C.

20.8 mL/hr

D.

62.5 mL/hr

Answer and Explanation

The Correct Answer is D

To calculate the rate of infusion, we need to divide the total volume to be infused (1.5 L) by the total time of infusion (24 hours)

1.5 L = 1500 mL (since 1 L = 1000 mL)

Dividing 1500 mL by 24 hours gives us the rate of 62.5 mL/hr.

Correct Answer is A

Explanation

To find the milligrams per minute, you need to calculate the following:

- The volume of Lopressor in milliliters
- The infusion rate in milliliters per minute using the formula: Infusion rate (mL/min) = Total volume (mL) / Time (min)
- The dose of Lopressor in milligrams per minute using the formula: Dose (mg/min) = Infusion rate (mL/min) x Concentration (mg/mL)


First, divide the dose of Lopressor by the concentration to get the volume in milliliters:


5 mg / 1 mg/mL = 5 mL

Next, use the formula for infusion rate to find how many milliliters per minute the IV pump should deliver:


Infusion rate (mL/min) = Total volume (mL) / Time (min)


Since the total volume is 5 mL and the time is 2 minutes, plug in these values into the formula:


Infusion rate (mL/min) = 5 mL / 2 min


Simplify and solve for the infusion rate:


Infusion rate (mL/min) = 2.5 mL/min


Then, use the formula for dose to find how many milligrams per minute the patient should receive:


Dose (mg/min) = Infusion rate (mL/min) x Concentration (mg/mL)


Since the infusion rate is 2.5 mL/min and the concentration is 1 mg/mL, plug in these values into the formula:


Dose (mg/min) = 2.5 mL/min x 1 mg/mL


Simplify and solve for the dose:


Dose (mg/min) = 2.5 mg/min


Therefore, the patient should receive **2.5 mg/min** of Lopressor.
