Question

The doctor orders Levaquin 350 mg to be added to 500 mL of D5W IV q 12 h. The stock supply is Levaquin 0.5g/5 mL. The drop factor is 20 gtt/mL. Calculate the flow rate of the IV in mL/h.

a. 42 mL

b. 42 mL/hr

c. 42 L/hr

d. 42.0 mL/hr

e. 41.67 mL/hr

Answer 1

ANSWER.

* Calculation of flow rate in ml/hr.

        Formula

            Flow rate = Volume(ml) / Time(hr)

     Here

          Volume(ml) = 500 ml.

            Time(hr) = 12 hr.

As per above formula

           Flow rate (ml/hr) = 500 / 12

                                    e = 41.67 ml/hr.
