Question 1 of 5
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.)
Correct Answer: 31 gtt/min
Rationale: Volume = 1,000 mL, time = 480 min, drop factor = 15 gtts/mL. Gtt/min = (1,000 ÷ 480) × 15 = 31.25, rounded to 31.
