Question

question 3 of 5, step 2 of 6
order: d₅w 750 ml iv for 5 h at 150 ml/h
drop factor: 15 gtt/ml
step 2 of 6: after 3.5 hours, there are 330ml remaining.
calculate the remaining time in hours.

Explanation:

Step1: Recall the rate - time - volume formula

The rate of infusion is 150 mL/h. The remaining volume is 330 mL. We use the formula $t=\frac{V}{r}$, where $t$ is time, $V$ is volume, and $r$ is rate.

Step2: Substitute values into the formula

$t=\frac{330}{150}$

Step3: Calculate the result

$t = 2.2$

Answer:

$2.2$
