Question 1 of 5
The physician orders a Lidocaine drip to infuse at 2 mg/min. The drug is available as 2 gm in 500 mL of fluid. Solve for mL/hr.
Correct Answer: 3
Rationale:
To solve for mL/hr, we first need to calculate the total mL infused in 1 min. Lidocaine concentration is 4 mg/mL (2 gm/500 mL). At 2 mg/min, the rate is 0.5 mL/min (2 mg/4 mg/mL).
To convert to mL/hr, we multiply by 60, giving us 30 mL/hr (0.5 mL/min x 60 min). Thus, the correct answer is 3. Other choices are incorrect because they do not follow the correct conversion steps or misinterpret the given information.
