Question

an IVPB bag contains 400 mg of drug in 50 mL of solution. if medication will infuse at a rate of 50mg/min how many milliliters will Infuse in 2 minutes?​

Answer 1

Drug will infuse in 2 minutes = 12.5 ml

Explanation:

Drug in 400 mg solution = 50 ml

Drug in 1 mg solution =
`(50)/(400) ml = (1)/(8) ml` ------ (1)

Drug infuse in 1 minute = 50 mg

Drug infuse in 2 minute = 50 × 2 = 100 mg

Now we have to convert this 100 mg into ml.

From equation (1)

Drug in 1 mg solution =
`(1)/(8) ml`

So Drug in 100 mg solution =
`(1)/(8)` × 100

So Drug in 100 mg solution = 12.5 ml

Therefore 12.5 ml will infuse in 2 minutes.
