Set the IV for 12.0 mL/h for 75 minutes
convert 75 minutes ---> hour
[tex]\begin{gathered} 60\min -\longrightarrow1hr \\ 75\min \longrightarrow x \\ x=\frac{75}{60}=1.25hr \end{gathered}[/tex]
The medication at 8am =
[tex]\frac{12mL}{h}\times1.25h=15mL[/tex]
convert 100 minutes ---> hour
[tex]\begin{gathered} 60\min -\longrightarrow1hr \\ 100\min \longrightarrow x \\ x=\frac{100}{60}=1.67hr \end{gathered}[/tex]
The medication at 4pm =
[tex]\frac{15mL}{h}\times1.67h=25mL[/tex]
Therefore
(a) The patient will recieve total medication of 15mL+25mL = 40mL
(b) The unit symbol for your answer = millilitres
