Head on impact Which of the preferred fluid for resuscitation of hemorrhagic shock in the prehospital setting? Lactated Ringer's Which is the most common cause of the upper airway obstruction? The tongue Which is the preferred adjunct device for verifying placement of the endotracheal tube in a patient with a perfusing rhythm? End tidal CO2 monitoring (Capnography) Which is the most important reason to maintain an open airway in the trauma patient? Prevents hypoxemia and hypercarbia Essential airway skills include manual clearing of the airway, manual maneuvers, suctioning, and which of the following Oropharyngeal airway Your patient is a middle aged male who crashed his motorcycle. He is unresponsive. After opening the airway using a modified jaw thrust you note the patient has respirations at a rate of 6. Auscultation reveals breath sounds are absent on the left side. Which of the following is the most appropriate next interventions? Begin ventilation with a BVM Which best describes shock? Generalized inadequate tissue perfusion Your patient has a deep laceration to his antecubital fossa with significant bleeding what is the most appropriate initial action? Apply direct pressure Hypotension of an unknown etiology in a trauma patient should be assumed to result from which of the following? Blood loss Which assessment is most beneficial in differentiating hemorrhagic shock from neurogenic shock in the prehospital setting? Skin The body initially compensates for blood loss through activation of which of the following? Systematic nervous system Medication used by trauma patients for pre-existing conditions may cause which of the following? Beta Blockers may prevent tachycardia with blood loss The target blood pressure for a trauma patient with suspected intra-abdominal hemorrhage is which of the following? 80-90 Which best explains the mechanism by which gas exchange is impaired in pulmonary contusion? Blood in the alveoli Which of the following is a key finding that differentiates cardiac tamponade from tension pneumothorax?

He demonstrates decerebrate posturing and has a GCS of 4. His heart rate is 58, bp 180/102, and his left pupil is dilated. What is the best ventilation rate to use when managing this patient? 20 A 20 year old female was ejected from her vehicle during a high speed rollover motor vehicle collision. she has significant bleeding from a large laceration. Your initial assessment reveals a GCS score of 7, systolic bp of 70 and pupils that are equal but slow to light. After establishing two large bore iv lines, you should titrate the infusion rate to achieve a target blood pressure of at least...? 90 Which of the following is the preferred prehospital wound management for a patient with a 36% body surface area flame burn? Dry, sterile dressings The most immediate life threatening condition resulting from injury to solid abdominal organs is which of the following? Hemorrhage An adult male sustained a deep laceration to his distal thigh. Bright red blood is spurting from the wound, direct pressure is not controlling the bleeding. What is the most appropriate next step? Apply tourniquet and tighten until bleeding stops
