CHAPTER 8: INTRAVENOUS THERAPY CALCULATIONSREVIEW TEST ________ IVPB________ microdrip________ macrodrip________ drop factor ________ mL/h________ gtt/min Number if drops needed to deliver 1 mL of fluid through IV tubingThe flow rate value for manually controlled IV infusions Administration of IV medications or fluids through a secondary lineIV tubing that delivers 10 gtt/mL, 15 gtt/mL or 20 gtt/mLIV tubing that delivers 60 gtt/mLFlow rate value for most electronically controlled IVsIV flow rates typically can be adjusted to within 25 percent of the original rateTrueFalseIV flow rates should always be adjusted so that the amount infused is caught back up within 2 hoursTrue False Intermittent peripheral infusion devices include the IVPB and the secondary setTrue False To calculate the flow rate in milliliters per hour, divide the total volume by the number of hours for the infusion TrueFalse To determine the number of minutes in an hour, multiply by 60True False Ordered: 1000 mL LR over 6 h. What is the flow rate in milliliters per hour?166.6 gtt/min167 mL/h167 gtt/min166.6 mL/hOrdered: 1000 mL NS over 24 h (20 gtt/mL tubing). What is the flow rate in drops per minute?14 mL/h42 mL/h14 gtt/min42 gtt/minOrdered: 250 mL D5W over 3 h by infusion pump. What is the flow rate?Ordered: 500 mL LR at 125 mL/h using microdrip tubing. What is the total time to infuse?Ordered: 500 mL ? NSS at 75 mL/h. The infusion started at 1615. When will the infusion be completed?Ordered: 1500 mL IV 1/3 NS q8h (10 gtt/mL tubing). What is the flow rate?Ordered: 1000 mL RL over 8 h (15 gtt/mL tubing). After 2 h, 125 mL has infused. What is the adjusted flow rate in drops per minute?Ordered: RL at 25 mL/h over 12 h. What is the volume to be administered?Ordered: 1000 mL at 125 mL/h, starting 1 p.m. When will this infusion be completed?9 a.m.10 p.m. 9 p.m.8 p.m.Which of the following can be a calibration factor of IV tubing? ................
