    A doctor orders 12 mg/kg of Acyclovir, the patient weighs 115 lbs. Acyclovir is supplied as 100 mg/2mL. How many mL will you administer per dose?

    Explanation & Rationale

    Given: Ordered dose of Acyclovir: 12 mg/kg Patient weight: 115 lbs Concentration of Acyclovir: 100 mg/2 mL Step 1: Convert patient weight from pounds to kilograms: 1 pound (lb) = 0.453592 kilograms (kg) Patient weight in kg = 115 lbs * 0.453592 kg/lb = 52.16308 kg Step 2: Calculate the total dose of Acyclovir: Total dose (mg) = Ordered dose (mg/kg) x Patient weight (kg) Total dose (mg) = 12 mg/kg x 52.16308 kg = 625.95696 mg Step 3: Calculate the volume to be administered: Volume (mL) = Total dose (mg) / Concentration (mg/mL) Volume (mL) = 625.95696 mg / 100 mg/2 mL Volume (mL) = 625.95696 mg x (2 mL / 100 mg) Volume (mL) = 12.5191392 mL Step 4: Round to the nearest tenth: Volume (mL) ≈ 12.5 mL/dose
