Question

How much IV fluid you would document as being infused (absorbed) from a 1000 mL bag if 75 mL are left in the bag? __________ mL

Answer 1

925 mL

Step-by-step explanation:

Givens

We are given that an IV bag has 1000 mL initially. At the end of the infusion, there is 75 mL left in the bag. We need to find how much of the initial volume was infused.

Therefore, we have:

• Initial volume - 1000 mL
• Infused volume - x mL
• Final volume - 75 mL

Solve

We can create an equation that relates the initial volume, infused volume, and final volume:

`\text{Initial volume - Infused volume} = \text{Final volume}`

Substitute the values into the equation (for the infused volume, use the variable x ):

`\text{1000 mL - } x \ \text{= 75 mL}`

Subtract 1000 mL from both sides of the equation:

`\text{1000 mL - } x \ \text{= 75 mL}\\\\\text{1000 mL - 1000 mL - } x \ \text{= 75 mL - 1000 mL}\\\\\text{-x } = \text{ -925 mL}`

Then, divide both sides by -1 to negate the negative x-value:

`\text{-x = -925 mL}\\\\\displaystyle \frac{\text{-x}}{\text{-1}} = \frac{\text{-925 mL}}{\text{-1}}\\\\\text{x = 925 mL}`

Therefore, 925 mL are absorbed/infused from the 1000 mL bag.
