Question 1 of 5
Order: 1000ml D5W at 120ml/hr. Available: Macro drop 15ml/hr. What is the drip factor in drops per minute?
Correct Answer: A
Rationale:
To calculate the drip factor in drops per minute, we use the formula: Drip factor = (Volume to be infused in ml) x (drop factor) / (Time in minutes). In this case, Volume = 1000ml, drop factor = 15 gtt/hr, and Time = 60 minutes (to convert 1 hour to minutes).
Therefore, Drip factor = (1000ml) x (15 gtt/hr) / (60 min) = 250 gtt/min. However, since the available drop factor is 15 ml/hr and not 1 ml/hr, we need to adjust by dividing by 5 (15 ml/hr ÷ 3 ml/hr = 5).
Therefore, the correct drip factor is 250 gtt/min ÷ 5 = 30 gtt/min (rounded to the nearest whole number).
Summary:
A: 30 gtt/min - Correct calculation.
B: 33 gtt/min - Incorrect calculation
