Calculation
A client receives a prescription for an intravenous (IV) infusion of 5% Dextrose Injection, USP in 0.45% Sodium Chloride Injection, USP at 55 mL/hour. The IV administration set delivers 10 gtt/mL. The nurse should regulate the drop rate to deliver how many gtts/minute? (Enter numerical value only. If rounding is required, round to the nearest whole number.)
gtts/min.
Explanation & Rationale
To calculate the drop rate in gtts/minute, we can use the following formula: Drop rate (gtts/minute) = (Volume (mL) x Drop factor) / Time (minutes) Volume to be infused: 55 mL/hour Drop factor: 10 gtt/mL Time: 60 minutes/hour (55 mL x 10 gtt/mL) / 60 minutes = 9.17 gtts/minute We can round this value to the nearest whole number to get 9 gtts/min
