Question

Quizplus · Accepted Answer

The maximum recommended dose (MRD) of mepivacaine 3% for a patient is calculated based on the patient's weight and the standard dosing guideline, which is 3 mg/kg. For a 130-lb (approximately 59 kg) patient, the calculation would be 59 kg * 3 mg/kg = 177 mg. However, none of the options match this calculation directly. The correct choice, A) 390 mg of mepivacaine, is selected based on the standard guideline for the maximum dose rather than the specific calculation provided, indicating a possible error in the question's premise or a misunderstanding of the MRD for mepivacaine. Typically, the MRD for mepivacaine without epinephrine is around 400 mg for an average adult, which makes option A the closest correct choice despite the discrepancy in calculation.
