You didn't say what the hourly rate is....can't help with out that information, you need to type the whole question.

With microbore tubing, the drop factor is 60 drops per ml.

Now you have the necessary information to complete this problem.

Please show us how you would do so.

If the rate is 60cc hour, which is unclear in this question divide 150 by 60 and you have your answer. This is a poorly written question.

I disagree that the question is poorly written. All the necessary information is there. The student must recognize it and convert it to another form in order to solve the problem. The instructor is looking for higher-level thinking on the part of the student, rather than spoon-feeding information.

Did you check the other thread? I showed how to set up the equation there.

micro
is microdrop tubing. its drop factor is 60 drops/ml. this is information that you have to know when you see the word
microdrops
written in a problem.

amount to give
: 150 ml (given information)

drop factor of iv tubing
: 60 drops/ml (given information)

rate of infusion
: 60 drops/minute (given information)

conversion factor
: 1 hour/60 minutes (you need this to work the problem)

by dimensional analysis:

1 minute/60 drops
(rate of infusion)
x 60 drops/ml
(drop factor of iv tubing)
x 150 ml/1
(amount to give)
x 1 hour/60 minutes
(conversion factor)
=
2.5 hours
