Your patient requires a maintenance dose of 3% hypertonic saline following a 250mL bolus. You have tubing with a drip factor of 15 gtt/mL. What is the gtt/min of the maintenance dose?

Explanation:
Converting an hourly IV maintenance rate into drops per minute using the drip factor is what this requires. The maintenance dose is 52 mL per hour. Drops per hour = 52 mL/hr × 15 gtt/mL = 780 gtt/hr. Drops per minute = 780 gtt/hr ÷ 60 min/hr = 13 gtt/min. The 3% saline concentration affects the amount of solute delivered, not the flow rate; the bolus is separate from the ongoing maintenance. If the maintenance volume changes, plug that new mL/hr into the same calculation.
