order: erythromycin 250 mg in 250 ml d5w to infuse over 3 hr. drop factor: 10 gtt/ml. how many gtt/min would you administer? (insert the numerical value only)

Explanation:

Step1: Convert hours to minutes

Since there are 60 minutes in an hour, for 3 hours, the number of minutes is \(3\times60 = 180\) minutes.

Step2: Use the formula \(gtt/min=\frac{Volume(mL)\times Drop - factor(gtt/mL)}{Time(minutes)}\)

Here, the volume \(V = 250\) mL, the drop - factor \(D = 10\) gtt/mL, and the time \(t=180\) minutes.
Substitute the values into the formula: \(\frac{250\times10}{180}=\frac{2500}{180}\approx13.89\)
