    Calculation

    A client scheduled for coronary artery bypass surgery is to receive an intravenous infusion of 1 gram cefazolin in 50 mL 0.9% Sodium Chloride, USP over 30 minutes. The nurse should program the infusion pump to deliver how many mL/hour? (Enter numeric value only, as a whole number.)

    mL/hour

    Explanation & Rationale

    First, convert the duration of infusion from minutes to hours by dividing by 60: 30 / 60 = 0.5 hours Next, divide the volume of fluid by the duration of infusion: 50 / 0.5 = 100 mL/hour The answer is 100 mL/hour.
