Practice Question
A nurse is preparing to administer 1,000 mL of lactated Ringer's IV over 6 hr. The drop factor of 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.)
Answer Choices:
Correct Answer:
28
Rationale:
Formula:
gtt/min = (Total volume mL ÷ Time min) × Drop factor
Step 1: Time = 6 hr × 60 = 360 min
Step 2: gtt/min = (1000 mL ÷ 360 min) × 10 gtt/mL
= 2.78 × 10
= 27.78 → 28 gtt/min
✅ Final Answer: 28 gtt/min
