The primary healthcare provider (PHCP) prescribes 100 mL of 0.9% sodium chloride (normal saline) to infuse over two hours via intravenous microdrip tubing. The nurse sets the flow rate at how many drops per minute? Fill in the blank. Round your answer to the nearest whole number.
Correct answer
50 drops per minute
Rationale
Microdrip tubing has a drop factor of 60 gtts/mL. Calculate: (100 mL ├âÔÇö 60 gtts/mL) ├â┬À (2 hr ├âÔÇö 60 min/hr) = 6000 gtts ├â┬À 120 min = 50 gtts/min.
