Order: lidocaine 2 g in 250 mL of D5W at 30 mL/h
What is the flow rate?
250 mL/hr
30 mL/hr
15 mL/hr
150 mL/hr
150 mL/hr
The Correct Answer is B
The order directly states that the infusion rate is 30 mL/hr.
The information about the amount of Lidocaine (2 g) and the volume of D5W (250 mL) is irrelevant to determining the flow rate in this case.
The flow rate is already specified as 30 mL/hr in the order.
