Question

At 1800 hours an IV is infusing at a rate of 20 gtt/min. How much can you expect the patient to receive during the next 7 hours and 20 minutes given a drop factor of 16 gtt/mL? Round your answer to the nearest mL.

Answer 1

..Given:

$\begin{gathered} R=20\frac{gtt}{\min } \\ T=7\text{hours and 20minutes} \\ F=16\frac{\text{gtt}}{mL} \end{gathered}$

To Determine: The number of mL

Calculate the total number of gtt for the time given

$\begin{gathered} 1\min =20\text{gtt} \\ 7\text{hours and 20minutes=7}\times60\min utes+20\min utes=420+20=440\min utes \\ 440\text{minutes}=440\times20gtt=8800gtt \end{gathered}$

using the drop factor

$\begin{gathered} 16\text{gtt}=1mL \\ 8800\text{gtt}=8800\times\frac{1}{16}mL=550mL \end{gathered}$

Hence, the mL the patient would receive is 550mL
