Answer:
[tex]Amount = 4000mL[/tex]
Explanation:
Given
[tex]IV\ Fluid = 75mg\ of\ 1000mL[/tex]
Required
Determine the infusion to give a patient that needs 300mg
First, we need to calculate the infusion rate
[tex]Infusion\ Rate = \frac{1000mL}{75mg}[/tex]
[tex]Infusion\ Rate = \frac{40}{3}mL/mg[/tex]
Next, we calculate the required amount for 300mg.
[tex]Amount = Infusion\ Rate * 300mg[/tex]
[tex]Amount = \frac{40}{3}mL/mg * 300mg[/tex]
[tex]Amount = \frac{40}{3}mL * 300[/tex]
[tex]Amount = \frac{40* 300}{3}mL[/tex]
[tex]Amount = 40* 100mL[/tex]
[tex]Amount = 4000mL[/tex]
Hence, the patient will be given 4000mL
