A patient is to receive 1.8 L of pain killer medication by intravenous drip that will take 1.5 hours to administer.
Given 1 mL = 4 drops, calculate the amount of drops per minute the machine must be set on. (2 marks)
--- 5 WORK AREA LINES (style=lined) ---
`text(80 drops per minute.)`
`text(Total drops required)=1800 xx 4=7200\ text(drops)`
`text{Time (in minutes)}=1.5 xx 60= 90\ text(minutes)`
`text(Drops per minute)=7200/90=80`
