A patient is ordered 1 unit of packed red blood cells (250mL) to be transfused over 120 minutes. The drop factor on the tubing is 15 gtt/mL. At what rate should the nurse regulate the IV (gtt/min)? (round to the nearest whole number)
The Correct Answer is ["31"]
Flow rate=(Total volume×Drop factor​)÷ Time in minutes
= (250×15)÷120
= 31.25

Correct Answer is B
Explanation
A. Assessment of neurologic status
While neurological assessment is important, it is not the priority in this situation. The immediate priority is managing the chest wound and airway to ensure oxygenation and prevent further complications.
B. Obtain IV access with two large bore lines and blood for lab studies
IV access is important for fluid resuscitation and medication administration but is not the immediate priority compared to securing the airway and ensuring ventilation.
C. Placement of a naso-gastric tube to decompress the stomach
