Ratios and proportion
Ratios are written as fractions or in the form a:b.
According to the question, An IV piggyback (IVPB) of 10,000 units/100 mL is to be given over 45 minutes.
We are to determine the number of mL to be given in 60 minutes (1 hr)
100mL = 45 minutes
x mL = 60 minutes
Take the ratio
100/x = 45/60
Cross multiply
45x = 6000
x = 6000/45
x = 133mL/hr
Hence the pump should be programmed to deliver 133mL/hr
