Question 1 of 5
A nurse is preparing to administer 400 mL of 0.9% sodium chloride IV over 8 hr. The drop factor of the manual IV tubing is 60 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.)
Correct Answer: 50 gtt/min
Rationale:
To calculate the drop rate, first convert the total volume to drops. 400 mL * 60 gtt/mL (drop factor) = 24000 gtt.
Then, divide the total drops by the total time in minutes (8 hr * 60 min/hr = 480 min) to get the drops per minute: 24000 gtt / 480 min = 50 gtt/min. This ensures the correct administration rate. Other choices would be incorrect due to incorrect calculations or misinterpretation of the question.
