Question

multiple choice 1 point calculate the flow rate in drops per minute for the following iv administrations. round to the nearest whole number. 3000 ml ns to infuse in 180 min. drop factor: 20 gtt/ml. 333.3 gtt/min 333 gtt/min 330 gtt/min 334 gtt/min

Explanation:

Step1: Recall the flow - rate formula

The formula for calculating the IV flow rate (drops per minute) is $\text{Flow rate (gtt/min)}=\frac{\text{Volume (mL)}\times\text{Drop factor (gtt/mL)}}{\text{Time (min)}}$.

Step2: Substitute the given values

We are given that the volume $V = 3000$ mL, the drop - factor $DF=20$ gtt/mL, and the time $t = 180$ min.
Substitute these values into the formula: $\text{Flow rate}=\frac{3000\times20}{180}$.

Step3: Perform the calculation

First, calculate $3000\times20 = 60000$. Then, $\frac{60000}{180}=\frac{1000}{3}\approx333.33$.

Step4: Round to the nearest whole number

Rounding $333.33$ to the nearest whole number gives 333 gtt/min.

Answer:

333 gtt/min
