Some help with IV calculation please!

[Nili927]

*Order: 40mg Lasix IVP

-Lasix 40 mg comes in 2 ml/ vial. 10 min 1hr

-Students cannot do IVP, therefore

*dilute in 8 ml of NS = total 10 ml.

*Run as "secondary"/ "piggy-back" on pump over 10 minutes.

How would you calculate the rate? I know it's 60ml/hr but I don't know the how to calculate it.

Can some one help me please!

By the way I have to say that I love this place, I don't post as much as I would like to but I read in here often and I have learned some very good tips from this place! I think everyone is great!

Maybe I'm not reading enough into the question, but from what I see...

10ml/10 min = 1ml/min

1ml/min * 60min/hr = 60ml/hr

That look right?

Meghan is correct. This problem comes down to a simple ratio. You know you have a total of 10mL that has to be given over a 10 minute period. You also have an IV pump that can only be programed as the number of mL per hour. So, it is easiest to set this up as a ratio and solve for X like this:

10mL

/

10min

=

x

mL

/

60min

(which is 1 hour)

Cross multiply to get

600

=

10XmL

then, solve for

X =

60mL

(the flow rate you program in to the pump)
