TNCC practice exam questions with correct answers

what is the key to high performance trauma team? effective communication 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 what? evaluating and anticipating the types of injury that may be present MOI and energy transfer can assist the provider in evaluating and anticipating damage what is the major preventable cause of death in the trauma patient? uncontrolled hemorrhage uncontrolled hemorrhage is the major cause of preventable death after injury so assessment to identify uncontrolled hemorrhage is key to the initial assessment process across the room observation in initial assessment provides the opportunity to do what? reprioritise circulation before airway and breathing across the room observation is done before the primary survey to rapidly assess the need to reprioritise circulation before airway or breathing if there is uncontrolled external bleeding which of the following accurately describes ventilation principles associated with a bag-mask device? ventilate at a rate of 10 to 12 breaths/minute if ventilation is ineffective assist ventilations at 10 to 12 breaths per minute or one every 5 to 6 seconds what is the best measure of the adequacy of cellular perfusion which helps predict the outcome of resuscitation? base deficit base deficits serve as an endpoint measurement of the adequacy of cellular perfusion and when used in conjunction with serum lactate help predict the success of the resuscitation safe pharmacological alternative to opioids for rib fracture pain management in the anticoagulated patient? intercostal nerve blocks 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 what? cerebral vasoconstriction hypocapnia or low levels of carbon dioxide will cause vasoconstriction, especially in the cerebral vasculature 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 conditions? spinal cord damage 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? apply gentle pressure over the iliac crests downward and medially 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 requires what to be closely observed and why? maintain adequate respiratory status C3 to C5 injuries can cause loss of phrenic nerve function resulting in a paralyzed diaphram and inability to breath what is the first step to stop bleeding of a penetrating injury to the lower extremity? initiate direct pressure first step is direct pressure second step is apply torniquet treatment for frostbite includes what? administer tissue plasminogen activator thrombus formation is a risk of frostbite tissue plasminogen activator or nonsteroidal antiinflammatory meds can be administered tissue plasminogen activator has been effective in maintaining perfusion and decreasing the need for amputation when administered within 24 hours 30 week pregnant patients bp is 94/62, HR 92 with fetal heart rate of 124 is this normal and why? normal vital signs in pregnancy resting heart rate increases by 10-20 beats in pregnancy with a small decrease in systolic BP and larg decrease in diastolic BP due to peripheral resistance normal fetal heart rate is 120 to 160 if a 13 month old involved in an MVA is co-operative, this may be a sign of what? mental status changes older alert infants or toddlers are usually cautious of strangers and may not respond to commands whats the best position for maintaining an open airway in the bariatric patient? reverse trendelenberg benefits both airway maintenance and work of breathing
