Question 1 of 5
Order: ceftriaxone 2 g in 100 mL of 0.9% NaCI (normal saline solution) over 30 minutes Available: Macro drip set: 15 gtt/mL Calculate the IV flow rate in gtt/min.
Correct Answer: A
Rationale:
To calculate the IV flow rate, we first need to determine the total volume to be infused over 30 minutes. Given 2g in 100mL, we have 100mL to infuse. Using the formula: (Volume to infuse in mL ÷ Time in minutes) × Drip factor = IV flow rate in gtt/min. Substituting the values, (100mL ÷ 30 min) × 15 gtt/mL = 50 gtt/min.
Therefore, the correct answer is A: 50 gtt/min. Option B (15 gtt/min) is incorrect as it does not consider the total volume and drip factor. Option C (10 gtt/min) is incorrect as it underestimates the flow rate. Option D (100 gtt/min) is incorrect as it overestimates the flow rate.
