ATI LPN Pharmacology Exam I Questions

Extract:


Question 1 of 5

The physician orders vancomycin 500 mg in 250 mL of D5W IVPB daily to infuse over 2 hours. Tubing drop factor is 15 gtts/mL. Calculate the flow rate in drops per minute.

Correct Answer: B

Rationale:
To calculate the flow rate in drops per minute, we first find the total volume to be infused per minute. 250 mL over 2 hours = 125 mL per hour = 125 mL/60 min = 2.08 mL/min. Next, convert mL to drops using the drop factor: 2.08 mL/min x 15 gtts/mL = 31.2 gtts/min, which rounds to 31 gtts/min.
Therefore, the correct answer is A.
Choice B (62 gtts/min) is incorrect as it does not align with the calculations.

Choices C and D are also incorrect, as they are not derived from the correct calculations.
