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: A
Rationale:
To calculate the IV infusion rate in gtt/min, we first convert 8 hours to minutes (8 hr x 60 min/hr = 480 min).
Then, we use the formula: (Volume to be infused in mL / Time in min) x Drop factor (gtt/mL). Plugging in the values: (400 mL / 480 min) x 60 gtt/mL = 50 gtt/min.
Therefore, the correct answer is A.
Choice B (25 gtt/min) is incorrect as it would be half the correct rate.
Choice C (100 gtt/min) is incorrect as it would be double the correct rate.
Choice D (75 gtt/min) is incorrect as it is closer to the correct rate but still incorrect.
