Question

An IV medication of 215 mL is to infuse at the rate of 70 mL/hr. What is the total infusion time?

Answer 1

The volume V is given by:

$V=RT$$\begin{gathered} \text{ Where} \\ R=\text{ the rate in mL} \\ T=\text{ the time in hours} \end{gathered}$

In this case,

$\begin{gathered} V=215\text{ mL} \\ R=70\text{ mL/hr} \end{gathered}$

Substituting V = 215 and R = 70, it follows that:

$\begin{gathered} 215=70T \\ \text{ Dividing both sides of the equation, it follows:} \\ T=\frac{215}{70}\approx3.07\text{ hours} \end{gathered}$

Therefore, the total infusion time is approximately 3.07 hours.
