Calculation
A nurse is preparing to administer 0.9% 1L to infuse over 8 hr. The drop factor of the manual IV tubing set is 15 gtts/ml. The nurse should set the manual IV infusion to deliver howmany gtt/min? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
gtt/min
Explanation & Rationale
Flow rate (gtt/min)= Total volume / Time×Drop factor (gtt/mL) Given: Total volume = 1000 mL (1 L) Time = 8 hours × 60 minutes = 480 minutes Drop factor = 15 gtt/mL Flow rate (gtt/min)= 1000 / 480×15= 31.25 (gtt/mL) Answer: 31 gtt/min (rounded to the nearest whole number)
