Calculation
A nurse is preparing to administer 0.9% sodium chloride 1 L IV to infuse over 8 hr. The drop factor of the manual IV tubing set is 15 gtts/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.) ______ gtts/min
gtts/min.
Explanation & Rationale
1 L = 1000 mL. Infusion time = 8 hours. mL per hour = 1000 mL ÷ 8 hr = 125 mL/hr. Drop factor = 15 gtts/mL. gtts per minute = (mL/hr × gtts/mL) ÷ 60 min/hr. Compute: 125 × 15 = 1875. 1875 ÷ 60 = 31.25 gtts/min. Round to nearest whole number → 31 gtts/min.
