Order: 1000 mL of D5›NS with 1 ampule of multiple vitamins to infuse over 8 hours Available: Macrodrip set: 15 gtt/mL Calculate the IV flow rate in gtt/min.
Correct answer
A
Rationale
To calculate the IV flow rate in gtt/min, first determine the total volume to infuse (1000 mL) over the total time (8 hours = 480 minutes). Then, calculate the flow rate using the formula: Flow rate (gtt/min) = Total volume (mL) / Total time (min). Substituting values, we get 1000 mL / 480 min = 2.08 mL/min. Next, convert mL/min to gtt/min using the drip factor (15 gtt/mL): 2.08 mL/min x 15 gtt/mL = 31.2 gtt/min. Since we can't have a fraction of a drop, round down to the nearest whole number, making the correct answer 31 gtt/min. Other choices are incorrect because they do not accurately result from the calculations.
