Question

2000ml iv saline is ordered over 24 hrs using drop factor of 15 drops /ml. how many drops per minute need to be given to the patient?

Answer 1

Answer:- 21 drops per minute.

Solution:- Total 2000 mL iv saline is ordered over 24 hours. the drop factor is 15 drops per mL. We are asked to calculate the drops per minute need to be given to the patient.

We could do this using dimensional analysis as:

$\frac{2000mL}{24hours}(\frac{15drops}{1mL})(\frac{1hour}{60minutes})$

= $\frac{21drops}{minute}$

So, 21 drops per minute need to be given to the patient.
