Question

Order: Infuse Aminophylline 250 mg in 250 mL at 30 mL/hr. Tubing factor: 60 gtts/mL. What is the quantity to administer? gtts/min. Round to a whole number.

Answer 1

ANSWER.

* Calculation of gtts/min.

        Formula

          Flow rate(gtts/min) = Total volume(ml) / Time(min) * Drop factor

       Here

         Total volume(ml) = 30 ml.

                   Time (hr) = 1 hr.

      Convert hr to min for calculation

           So

                  Time(Min) = 60 min.

             Drop factor = 60 gtts/ml.

    Flow rate (gtts/min) = 30/60 * 60

                                     = 30 gtts/min.
