gtt/min is a common abbreviation used to describe the rate
at which a medicine is administered. gtt comes from the Latin word "guttae" which means
drops.
Here we have a 350 mL solution that contains 45 g of
medication and is delivered over 2.5 hours at a 25 drop
set.
The 25 drop set indicates that each mL is equal to 25
drops. 350 mL is equal to 350*25 = 8750 drops. This is administered in 2.5 hours or
2.5*60 = 150 minutes.
The rate in gtt/min of the solution
being administered is 8750/150 = 58.33.
The correct answer
is option d or 58.3 gtt/min.
