Order: 1 liter or 1000 mL of D5W to infuse over 6 hours Available: Macrodrip set: 10 gtt/mL The IV flow rate would be ______gtt/min.
Correct answer
A
Rationale
To calculate the IV flow rate in gtt/min, we first convert 1 liter to mL (1 L = 1000 mL). Then, we divide the total mL by the total hours to infuse (1000 mL / 6 hours = 166.67 mL/h). Next, we multiply the mL/h by the drip factor (166.67 mL/h x 10 gtt/mL = 1667 gtt/h). Finally, we convert gtt/hr to gtt/min by dividing by 60 (1667 gtt/h / 60 min = 27.78 gtt/min, rounded to 28 gtt/min). Therefore, the correct answer is A (28 gtt/min). Other choices are incorrect because they do not follow the correct calculations or have rounding errors.
