A) Neurogenic B) Cardiogenic C) Hypovolemic D) Hemorrhagic 2) Which of the following guidelines applies to the prehospital administration of IV fluids in the patient with hemorrhagic shock? A) Administer hypertonic saline solution or colloids at a keep-open rate. B) Administer synthetic oxygen-carrying fluids as necessary to increase the level of consciousness. C) Begin with a 2,000 ml bolus of isotonic crystalloid solution infused under pressure. D) Administer isotonic crystalloid fluids only as necessary to maintain perfusion. 3) Your patient is a 23-year-old male with a gunshot wound to the abdomen and an exit wound in the right flank. He responds to verbal stimuli; has pale, cool, diaphoretic skin; and has a heart rate of 128, respirations at 24, and a blood pressure of 82/60. These findings indicate which of the following kind of shock? A) Compensated B) Irreversible C) Decompensated D) Neurogenic 4) Your patient is a 42-year-old male with multiple lacerations on his arms, head, and torso after falling through a plate-glass window. On your arrival he appears to be unresponsive, lying prone on the sidewalk. Which of the following is the correct sequence of actions in caring for this patient? 1. Control major hemorrhage. 2.
