Question 1 of 5
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)
Correct Answer: 16 mL
Rationale:
To calculate the dosage of Vancomycin, convert the patient's weight to kilograms (110 lbs / 2.2 = 50 kg). Multiply by the prescribed dosage (50 kg * 20 mg/kg = 1000 mg). The vials contain 500 mg per 8 mL, so 1000 mg requires 16 mL (1000 mg / (500 mg/8 mL)).
