Explanation / Answer

18. Drops per min = volume (ml) /time (min) x drop factor( gtt/ml)

Volume = 125ml

Time= 1hr or 60min

Drop factor= 10gtt/ml

Drops per min = 125/60 x 10 = 21gtt/min

19. Volume = 150ml

Time = 1hr or 60 min

Drop factor = 15gtt/ml

Flow rate = 150/60 x 15 = 37gtt/min

20. Volume = 50cc or 50 ml

Time = 1hr or 60 min

Drop factor = 60gtt/ml

Flow rate= 50/60 x 60 = 50gtt/min
