You are transporting a conscious middle-aged man with anterior neck trauma. He is on high-flow oxygen, has spinal precautions in place, and has a large-bore IV line of normal saline in place. When you reassess his vital signs, you note that his blood pressure is 90/64 mm Hg, his pulse rate is 120 beats/min, and his respirations are 22 breaths/min with adequate depth. You should:
A) begin assisting his ventilations with a bag-mask device, rapidly infuse 2 L of IV fluid, and reassess.
B) keep the patient warm and infuse enough isotonic crystalloid solution to maintain adequate perfusion.
C) elevate his legs, apply a blanket, and administer IV fluid boluses until his heart rate is within a normal range.
D) start a second IV line and administer crystalloid IV fluids until his systolic blood pressure is at least 100 mm Hg.
Answer: B) keep the patient warm and infuse enough isotonic crystalloid solution to maintain adequate perfusion.
