Here’s a sample NCLEX question with IV calculation:
A nurse cares for a child receiving 40 drops of IV fluid per minute. IV set has a drip factor of 60 drops per ml. How many hours it will take to infuse 400ml ?
So to get the answer 0.67ml = 1 min
400ml = X
If you cross-multiply and solve for X it will be 400 divided by 0.67 which is 597 min about 9.95 hours.
