Question 1 of 5
The patient has Levaquin 500 mg ordered once daily. The Levaquin is available in 100 mL of NS and should infuse over 1 hour. Using tubing with a 60 gtt/mL drop factor, how many drops per minute should the Levaquin be infused?
Correct Answer: B
Rationale: The correct answer is B: 100 gtts/min.
To calculate the infusion rate in drops per minute (gtts/min), we use the formula: (Volume to be infused in mL) x (Drop factor) / (Time in minutes). In this case, the volume is 100 mL, drop factor is 60 gtt/mL, and time is 60 minutes. Plugging these values into the formula: (100 mL) x (60 gtt/mL) / 60 min = 100 gtts/min. This ensures the Levaquin infuses over 1 hour at the correct rate.
Choices A, C, and D are incorrect as they do not align with the correct calculation based on the given parameters.
