Ask the student a question, and give any hints about how they should answer this part.

Your patient is ordered $\var{V}$ mL of intravenous (IV) normal saline. If the IV is set at $\var{r}$ mL/hr, how long will it take to deliver the fluid?

Gap 0. hours Gap 1. minutes

Advice

$\begin{align}\text{time (hr)}&=\frac{\text{volume (mL)}}{\text{flow rate (mL/hr)}}\\&=\frac{\var{V}\text{ mL}}{\var{r} \text{ mL/hr}}\\&=\var{h} \text{ hours and } 0 \text{ minutes} \end{align}$

$\begin{align}\text{time (hr)}&=\frac{\text{volume (mL)}}{\text{flow rate (mL/hr)}}\\&=\frac{\var{V}\text{ mL}}{\var{r} \text{ mL/hr}}\\&\approx \var{time} \text{ hours} \\&=\var{h} \text{ hours and } \var{m} \text{ minutes}\end{align}$

$\begin{align}\text{time (hr)}&=\frac{\text{volume (mL)}}{\text{flow rate (mL/hr)}}\\&=\frac{\var{V}\text{ mL}}{\var{r} \text{ mL/hr}}\\&= \var{time} \text{ hours} \\&=\var{h} \text{ hours and } \var{m} \text{ minutes}\end{align}$
