A physician prescribes Vancomycin 20 mg/kg intravenous (IV). The patient weighs 110 lbs. The medication is available in vials which contain 500 mg per 8 mL. What should the nurse withdraw from the vial? (round to the nearest whole number)

Answer and Explanation

The Correct Answer is ["16"]

To calculate the dosage of Vancomycin, first convert the patient's weight from pounds to kilograms, knowing that 1 kg equals 2.2 lbs. The patient weighs 110 lbs, which is equivalent to 50 kg (110 lbs / 2.2). Next, multiply the patient's weight in kilograms by the prescribed dosage of 20 mg/kg, resulting in a total dosage of 1000 mg (50 kg * 20 mg/kg). Since the vials contain 500 mg per 8 mL, divide the total dosage required by the amount per vial to find out how many milliliters should be withdrawn. This results in 16 mL (1000 mg / (500 mg/8 mL)).
