Question

1. the physician has ordered garamycin 100 mg/100 ml q8hrs ivpb. using a 15 gtt/ml drop factor, calculate the gtt per minute needed to give the medication over 60 minutes. round the answer to the nearest whole number.

Explanation:

Step1: Identify the formula

The formula for calculating drops per minute (\(gtt/min\)) is \(gtt/min=\frac{Drop\ factor\times Volume}{Time}\).

Step2: Substitute the values

Here, the drop factor is \(15\ gtt/mL\), the volume \(V = 100\ mL\), and the time \(t=60\ min\).
Substitute these values into the formula: \(gtt/min=\frac{15\times100}{60}\).

Step3: Calculate the result

First, calculate \(15\times100 = 1500\). Then, \(\frac{1500}{60}=25\).

Answer:

\(25\ gtt/min\)
