Question

An IV fluid contains 75mg of drug B in a 1000ml of the iV fluid if the patient needs 300mg of this medication how much of this IV fluid should be infused ?

Answer 1

`Amount = 4000mL`

Step-by-step explanation:

Given

`IV\ Fluid = 75mg\ of\ 1000mL`

Required

Determine the infusion to give a patient that needs 300mg

First, we need to calculate the infusion rate

`Infusion\ Rate = (1000mL)/(75mg)`

`Infusion\ Rate = (40)/(3)mL/mg`

Next, we calculate the required amount for 300mg.

`Amount = Infusion\ Rate * 300mg`

`Amount = (40)/(3)mL/mg * 300mg`

`Amount = (40)/(3)mL * 300`

`Amount = (40* 300)/(3)mL`

`Amount = 40* 100mL`

`Amount = 4000mL`

Hence, the patient will be given 4000mL
