An infant is ordered 50mL packed red blood cells to infuse over 2hr. The drop factor of the gravity tubing is 15gtts/mL. The nurse would adjust the flow rate to how many gtts/min? (Round to a whole number).

Total volume = 50 mL Time = 2 hr = 120 minutes Drop factor = 15 gtts/mL Flow rate (gtts/min) = (Volume × Drop factor) ÷ Time = (50 × 15) ÷ 120 = 750 ÷ 120 = 6.25 → Round to whole number = 6 gtts/min Final Answer: 6 gtts/min
