TNCC PRACTICE EXAM WITH CORRECT ANSWERS

TNCC PRACTICE EXAM WITH CORRECT ANSWERS What is the key to a high performing trauma team? - CORRECT ANSWER-effective communication rationale: skilled communication, cooperation, and coordination are the cornerstones of high-performance teams and high-quality trauma care When obtaining a history for an injured patient, understanding the kinematic concepts associated with the mechanism of injury and energy transfer can initially assist the trauma provider in: - CORRECT ANSWER-evaluating and anticipating the types of injuries that may be present rationale: mechanism of injury and energy transfer can assist the provider in evaluating and anticipating damage the major preventable cause of death in the trauma patient is: - CORRECT ANSWERuncontrolled hemorrhage rationale: uncontrolled hemorrhage is the major cause of preventable death after injury, so assessment to identify uncontrolled hemorrhage is key to the initial assessment process the across-the-room observation step in the initial assessment provides the opportunity to - CORRECT ANSWER-reprioritize circulation before airway or breathing rationale: the across-the-room observation is done at the beginning of the primary survey to rapidly assess the need to reprioritize circulation before airway or breathing. This is done if uncontrolled external hemorrhage is identified. Which of the following accurately describes ventilation prinicples associated with a bagmask device? - CORRECT ANSWER-ventilate at a rate of 10-12 breaths/minute rationale: if ventilation is ineffective, assist ventilation at 10-12 breaths/minute or one every 5-6 seconds Which of the following is the best measure of the adequacy of cellular perfusion and helps to predict the outcome of resuscitation? - CORRECT ANSWER-base deficit rationale: base deficit serves as an endpoint measurement of the adequacy of cellular perfusion and when used in conjunction with serum lactate helps predict the success of resuciation What is the safe pharmacological alternative to opioids for rib fracture pain management in the anticoagulated patient? - CORRECT ANSWER-intercostal nerve blocks rationale: continuous intercostal nerve blocks use long-acting anesthetics and can provide safe and effective pain management for the anticoagulated patient. In a patient with severe traumatic brain injury, hypocapnia causes: - CORRECT ANSWER-cerebral vasoconstriction rationale: hypocapnia, or low levels of carbon dioxide, will cause vasoconstriction, especially in the cerebra; vasculature A patient with a knife injury to the neck has an intact airway and is hemodynamically stable. He complains of difficulty swallowing and speaking. Further assessment is indicated next for which of the following? - CORRECT ANSWER-damage to spinal cord rationale: penetrating neck trauma may include concurrent injuries to the spinal cord, airway, or vascular neck structures. With an intact airway and hemodynamic stability, the other common concurrent injury is to the spinal cord What is the appropriate technique for palpating the pelvis for stability? - CORRECT ANSWER-apply gentle pressure over the iliac downward and medially rationale: to assess for pelvic instability, gentle pressure is applied over the iliac crests downward and medially a patient with a spinal cord injury at C5 is being cared for in the emergency department while awaiting transport to a trauma center. which of the following represents the highest priority for ongoing assessment and management? - CORRECT ANSWERmaintain adequate respiratory status rationale: spinal cord injuries at C3 to C5 can cause the loss of phrenic nerve function, resulting in a paralyzed diaphragm and inability to breathe Based on proper bleeding control techniques, what is the first step to stop the bleeding of a penetrating injury to the lower extremity? - CORRECT ANSWER-initiate direct pressure rationale: the first step in controlling any bleeding is direct pressure. if that is not adequate, the application of a tourniquet may be needed
