number 19

16. An Ⅳ bag has 350 mL remaining. It is infusing at 35 gtt/min, and a 15 gtt/mL set is being used. How long will it takg to finish? 18. A patient must have a tube feeding of 1,000 mL Ensure for 10 hours. The drop factor is 15 gtt/mL. After 5 hours, a total of 650 mL has in- fused. Recalculate the new gtt/min flow rate to complete the infusion on schedule. 6at mi 19.An Ⅳis infusing at a rate of 30 drops per minute. The drop factor is ail Cilan e l l 1Sgtt/mL. Calculate the flow rate in milliliters per hour

Answer 1

ANSWER.

16) Calculation of time taken for finishing the IV infusion.

             Formula

               Rate (gtt/min) = Total volume(ml) / Time * Drop factor.

            So

                   Time = Total volume / Rate * Drop factor.

              Here

                       Total volume = 350 ml.

                          Rate = 35 gtt/min.

                          Drop factor = 15 gtt/ml.

            As per formula

                         Time = 350 / 35 * 15

                                  = 10 * 15

                                  = 150 min.

                                  = 2 hour 30 minutes.

18) Calculation of new gtt/min flow rate of the patient.

              Formula

                   Flow rate (gtt/min) = Total volume / time * Drop factor.

              Here

                   Total volume = 1000 - 650

                                        = 350 ml.

                         Time = 10 - 5

                                        = 5 hr.

                                        = 300 min.

                       Drop factor = 15 gtt/ml.

         As per formula

                     Flow rate = 350 / 300 * 15

                                  = 1.16 * 15

                                  = 17.5 gtt/min.

19) Calculation of flow rate in ml per hour.

                 Formula

                         gtt/min = ml/hr * Drop factor / 60

                           ml/hr = gtt/min * 60 / drop factor.

                    Here

                          Rate (gtt/min) = 30 gtt/min.

                          Drop factor = 15 gtt/ml.

           As per formula

                     ml/hr = 30 * 60 / 15

                              = 1800 / 15

                      Flow rate (ml/hr) = 120 ml/hr.
