A nurse is preparing to administer 1,000 mL of lactated Ringer’s IV over 6 hours. The drop factor of the manual IV tubing is 10 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (Round to the nearest whole number.)

Choice A reason: To calculate the rate: (1000 mL ÷ 360 min) × 10 gtt/mL = 27.78 ≈ 28 gtt/min. This is the correct rounded value for safe and accurate infusion. Choice B reason: 30 gtt/min would result in a faster infusion than prescribed, risking fluid overload. Choice C reason: 27 gtt/min is slightly below the calculated rate and may delay fluid delivery. Choice D reason: 29 gtt/min is close but not the correct rounded value from the calculation.
