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

Answer:

$Amount = 4000mL$

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

$Infusion\ Rate = \frac{1000mL}{75mg}$

$Infusion\ Rate = \frac{40}{3}mL/mg$

Next, we calculate the required amount for 300mg.

$Amount = Infusion\ Rate * 300mg$

$Amount = \frac{40}{3}mL/mg * 300mg$

$Amount = \frac{40}{3}mL * 300$

$Amount = \frac{40* 300}{3}mL$

$Amount = 40* 100mL$

$Amount = 4000mL$

Hence, the patient will be given 4000mL
