    Calculation

    A nurse is preparing to administer 0.9% sodium chloride (NSS) 3000 mL IV to infuse over 24 hr. The drop factor on the manual IV tubing is 10 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

    gtt/min

    Explanation & Rationale

    Rationale: Total volume = 3000 mL Infusion time = 24 hr × 60 min/hr = 1440 min Drop factor = 10 gtt/mL Step 1: Calculate mL/min: 3000 mL ÷ 1440 min = 2.083 mL/min Step 2: Calculate gtt/min: 2.083 mL/min × 10 gtt/mL = 20.83 gtt/min = 21 gtt/min Final Answer: 21 gtt/min
