An infusion of lidocaine hydrochloride (Xylocaine) is running at 30 mL/hour. The dilution is 1,000 mg/250 mL. What dosage is the client receiving per minute?

Correct Answer: 2 mg/minute.

Rationale: Calculate: 1,000 mg in 250 mL = 4 mg/mL. At 30 mL/hour, that's 30 mL × 4 mg/mL = 120 mg/hour. Per minute: 120 mg ÷ 60 min = 2 mg/minute.
