Question

complete the following calculation of iv flow rate.

the answer is drops per minute.
(round to the nearest whole number as needed.)

Explanation:

Step1: Convert time to minutes

The time \(t = 2\frac{1}{2}\) hours. Since \(1\) hour \(= 60\) minutes, \(t=2.5\times60 = 150\) minutes.

Step2: Use the IV flow - rate formula

The formula for IV flow rate (drops per minute) is \(R=\frac{V\times gtt/mL}{t}\), where \(V\) is the volume of fluid (\(V = 500\) mL), \(gtt/mL\) is the drop factor (\(gtt/mL=20\)), and \(t\) is the time in minutes.
Substitute the values into the formula: \(R=\frac{500\times20}{150}\).
First, calculate \(500\times20 = 10000\). Then, \(R=\frac{10000}{150}\approx66.67\).

Answer:

\(67\) drops per minute.
