The factors used to establish the preference in treating the patient include all except: a) Condition of the patient b) Equipment available c) Situation that exists d) Research information - Research information Approximately 20% of all child abuse is the result of intentional burning. The majority of the children intentionally burned are of what age? a) 10 to 12 years of age b) 5 to 6 years of age c) 1 to 2 years of age d) Less than 1 year of age - 1 to 2 years of age In addition to glucose, what is required to maintain the metabolic processes of life and energy production? a) Carbon monoxide b) Krebs cells c) Lymphocytes d) Oxygen - Oxygen You respond to a patient who has sustained a stab wound to the left upper thorax. She is barely responsive, pale and diaphoretic. Which of the following is the most appropriate for transport? a) Stair chair b) Long board with spinal motion restriction c) Scoop stretcher d) Short immobilization device - Scoop stretcher Units responding to a motor vehicle accident on the highway should consider which of the following as part of their pre-arrival assessment? a) Calling for more units to respond b) Weather conditions c) The need for immediate transport d) Post-exposure prophylaxis - Weather conditions The most appropriate airway maneuver in the initial management of a trauma patient is which of the following? a) Head tilt, chin lift b) Supraglottic airway c) Trauma jaw thrust d) Oropharyngeal airway - Trauma jaw thrust When verifying ET tube placement on a perfusing patient, the "gold standard" of monitoring is considered to be? a) Colorimetric carbon dioxide detector b) Pulse oximetry c) Listening to lung sounds d) Waveform capnography - Waveform capnography A patient presents with a blunt trauma injury to the chest. On exam, he has absent breath sounds on one side of his chest and respiratory distress. Which additional sign would indicate that the patient has a tension pneumothorax? a) Distended neck veins b) Inspiratory wheezing c) narrowed pulse pressure d) Tracheal deviation towards the side of injury - Distended neck veins Hemostatic agents should be used for excessive bleeding when direct pressure alone does not work. The proper way to use most hemostatic agents is which of the following? a) Placing the agent around the edges of the wound b) Placing the agent properly into the wound and holding direct pressure c) Only using it after a tourniquet has been applied for 10 minutes d) Hemostatic agents should never be used unless you have a fall in blood pressure - Placing the agent properly into the wound and holding direct pressure Of the following, which is a preventable cause of secondary brain injury addressable during the transport phase? a) Intraparenchymal hemorrhage b) Systemic hypoxia c) Intracranial hematomas d) Herniation syndromes - Systemic hypoxia You are called to treat a patient who was knocked unconscious when he slipped and fell on a wet floor, striking his head. It is now several hours later. He is awake but confused, does not recall the incident, and is vomiting with a headache. Which of the following injuries is most likely? a) Brain herniation b) Intraabdominal hemorrhage c) Diffuse axonal injury d) Concussion - Concussion When using a selective spinal immobilization protocol, which of the following findings indicate the need for immobilization? a) Past history of spinal injury b) Being an unrestrained passenger in a motor vehicle crash c) Being ambulatory at the scene d) An associated femoral shaft fracture with severe pain - An associated femoral shaft fracture with severe pain In a blast-related multiple patient situation, which of the following patients should be treated first? a) A 33-year-old female with altered level of consciousness and decreased capillary refill b) A 28-year-old male with an arm amputation who has bleeding controlled with a tourniquet c) A 14-year-old pulseless female with grey matter visible from a head wound d) a 78-year-old male awake and unable to hear - A 33-year-old female with altered level of consciousness and decreased capillary refill Excessive fluid resuscitation of the trauma patient can result in which of the following? a) Worsening coagulopathy b) Decreased mortality c) Earlier discharge from the hospital d) A higher incidence of sepsis in the ICU - Worsening coagulopathy The secondary survey should be accomplished: a) Never on a critical patient b) Before transport c) When time and situation allow d) Before moving the patient - When time and situation allow When approaching a trauma patient, what is the first assessment that must be made? a) Exsanguinating hemorrhage b) Scene safety c) Airway d) Breathing - Scene safety The most common type of shock resulting from trauma is? a) Neurogenic b) Septic c) Spinal d) Hemorrhagic - Hemorrhagic Which of the following best guides the decision to provide spinal immobilization? a) History and complaint b) Obvious signs of associated injury c) Patient's age and presence of pressure sores d) Mechanism alone - History and complaint A 38-year-old male sustains a large wound to his right thigh while at work. Which of the following actions is the most important initial step? a) Obtain IV access and infuse crystalloid b) Administer supplemental oxygen c) Hemorrhage control d) Rapid transport - Hemorrhage control You respond to a local bar for an unconscious person. On arrival, you are met by a police officer who reports that one of their "regular alcoholics" was found in the alley behind the bar. On exam, you note the smell of an alcoholic beverage as well as the following: Patient flexes his arms to painful stimuli, has bilateral fixed and dilated pupils, irregular respirations at 12 breaths per minute and a BP of 210/100.
