What is the required dose of Vancomycin for a patient weighing 165 lb if the order is for 10 mg/kg?

To determine the required dose of Vancomycin for a patient, the first step is to convert the patient’s weight from pounds to kilograms, as the dosing is specified in mg/kg.

1. Convert the patient's weight: Since there are approximately 2.2 pounds in a kilogram, divide the weight (165 lb) by 2.2 to get the weight in kilograms:

165 lb ÷ 2.2 = approximately 75 kg.

2. Now, calculate the dose based on the prescribed amount of 10 mg/kg. Multiply the patient’s weight in kilograms (75 kg) by the dose per kilogram (10 mg/kg):

75 kg × 10 mg/kg = 750 mg.

3. The calculation indicates that the required dose is 750 mg.

Given this reasoning, the correct answer is not 1500 mg but rather 750 mg, which would align with the calculated value when following the proper conversion and calculation steps. The point of confusion might stem from miscalculating the conversion or applying the dosing without appropriate weight adjustments.
