Question

A patient is to receive 1.08 L of fluid over 3 hours through an IV drip. There are 16 drops/ml. How many drops per minute are required

Answer 1

How many drops per minute?
There are 16 drops per ML.

1000 ML  =    1 L.
1L  =  1000 ML

Therefore 1.08 L  =  1.08 * 1000 = 1080 ML

16 drops  per ML means I ML has 16 drops.

Therefore 1080 ML has:    (1080 * 16) drops.

Number of drops per min:
Since the entire process took 3 hours =  3 * 60 minutes = 180 minutes.

Therefore Number of drops per minute  = Number of Drops / Time in minutes
                                                        = (1080 * 16) /(180)
                                                        = 96 drops per minute.
