Drops per minute (DPM)-Worksheet Answers
Answer 1
Total volume = 280 ml
Total time to administer= 4 hours
Drop factor = 60
So, Drops per minute (DPM) =
280
4 × 60
60 = 280
4= 70 drops per minute
Answer 2
Total volume = 750 ml
Total time to administer= 6 hours
Drop factor = 20
So, Drops per minute (DPM) =
750
6 × 20
60 = 15000
360 = 41.66
Answer 3
Total volume = 3 L = (3 × 1000) = 3000 mls
Time= 6 hours
Drop factor = 15
So, Drops per minute (DPM) =
3000
6 × 15
60 = 3000
24 = 125
