Dosage test...concentration problem

Nursing Students Student Assist

Published

Please help! I am studying for an advanced dosage calculation test and am stuck on one set of the problems. One problem is as follows: heparin 25,000 units in 250 mL D5W @ 1000 units/hr.

We have to answer the following questions: what is the concentration, what would be the vol/min, what would be the concentration/min. If anyone can help me with this problem, I can figure out the rest. I've looked in my text books but we briefly covered this the beginning of last semester and I can't find my notes anywhere. Thank you in advance!!!

17 units per min?

That is correct Grasshopper.

Since concentration is 100ml/hr and 0.17 is ml per min,

then what is the concentration per min?

It's not "concentration per minute," it's dose per minute. Concentration is not a time-dependent variable. Didn't you take chemistry? If not, you will have to. I hope.

It was a typo and yes, I took chemistry
