What is the maintenance infusion rate for Lidocaine after an initial dose of 1 mg/kg?

The maintenance infusion rate for Lidocaine after an initial dose of 1 mg/kg is correctly indicated as 2 mg/min or 30 gtts/min. This dosage reflects standard protocols for maintaining therapeutic levels of the drug in cases such as ventricular arrhythmias, where continuous infusion is necessary following the initial bolus. The calculated infusion rate ensures that adequate plasma concentrations of Lidocaine are maintained without reaching toxicity levels.

The alternative rates provided in the other options do not align with the established guidelines for Lidocaine administration, which can lead to ineffective treatment or increased risk of adverse effects. The correct answer specifically ensures an effective therapeutic window while minimizing potential side effects, vital for patient safety during emergency medical interventions.
