Gap-fill

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

$\var{v}$ mL of a fluid is to be infused over $\var{h}$ hours using a microdrop giving set which delivers $\var{dropfactor}$ drops/mL. Calculate the required drip rate in drops per minute.

Unnamed gap dpm (to the nearest whole number)

Advice

$\begin{align}\text{drip rate (dpm)}&=\frac{\text{drops}}{\text{minutes}}\\&= \frac{\text{volume (mL)}\times \text{drop factor (drops/mL)}}{\text{hours (hr)}\times 60 \text{ (min/hr)}}\\&=\frac{\var{v} \text{ mL}\times \var{dropfactor} \text{ drops/mL}}{\var{h} \text{ hr}\times 60 \text{ min/hr}}\\&=\frac{\var{v} \text{ drops}}{\var{h} \text{ min}}\\&=\var{dpmrounded} \text{ drops/min (to the nearest whole number)}\end{align}$
