Question 1 of 5
Following surgical repair of a fractured femur, a client's hemoglobin falls to 7.4 and the physician orders one unit of packed red blood cells (250 mL) to be administered over two hours with a drop factor of 10 drops/mL. What flow rate (drops per minute) is needed? Record by rounding to the nearest whole number.
Correct Answer: 21
Rationale:
To calculate the flow rate: (Volume X Drop factor)/ Time in minutes. Volume is 250 mL, drop factor is 10 drops/mL, time is 2 hours = 120 minutes. Thus, (250 X 10)/ 120 = 2,500/ 120 ≈ 20.83, rounded to 21 drops/minute.
