TNCC Exam 9th Edition Study Final Actual Exam Prep Questions & Answers Verified 100% Correct .During the primary survey of an unconscious patient with multi-system trauma, the nurse notes snoring respirations. What priority nursing intervention should be performed next? - ANSWER Insert an oropharyngeal airway if there is no gag reflex Snoring respirations may indicate airway obstruction from the tongue. Insert an airway adjunct to alleviate obstruction by the tongue. Oropharyngeal airways can be used in patients without a gag reflex. What bedside monitoring parameters are used to assess for adequacy of oxygenation and effectiveness of ventilation? - ANSWER Pulse oximetry and capnography Pulse oximetry measures the percentage of hemoglobin saturated with oxygen. Capnography measures the amount of carbon dioxide exhaled. Carbon dioxide is the end-product of ventilation and a reflection of metabolism and pulmonary function. Which of the following is NOT considered a benefit of debriefings? - ANSWER Identifying individuals who made mistakes during the traumatic event Debriefings are not used to single out individuals who made mistakes. Debriefings are used to provide an opportunity to review performance and identify areas for improvement with a sharing of individual responses. Which of the following is NOT considered goal-directed therapy for cardiogenic shock? - ANSWER Pericardiocentesis A pericardial tamponade is a form of obstructive, not cardiogenic, shock. A patient is brought to the emergency department of a rural hospital following a high-speed motor vehicle collision. When significant abdominal and pelvic injuries are noted in the primary survey, which of the following is the priority intervention? - ANSWER Initiate transfer to a trauma center Early consideration for transfer to a trauma center is essential to ensure optimal outcomes. The most reassuring finding for a male patient with hip pain after a fall is which of the following? - ANSWER Pelvic stability Uncontrolled hemorrhage is the major cause of preventable death after injury. Unstable pelvic fractures increase the volume of the pelvic cavity and can be lifethreatening due to blood loss. EMS brings a patient from a motor vehicle crash. Vital signs are BP 90/49 mm Hg, heart rate 48 beats/minute, respiratory rate 12 breaths/minute, temperature 97.2°F (36.2° C). The patient exhibits urinary incontinence and priapism. These assessment findings are most consistent with which of the following types of spinal cord injury? - ANSWER Complete Incontinence, priapism, and hypotension with bradycardia are manifestations of a complete spinal cord injury. What physiologic change in the elderly population increases the risk of traumatic injury? - ANSWER Decreased subcutaneous fat Decreased subcutaneous fat and thinning of the skin increases the risk of injuries from soft tissue trauma and increases the risk of hypothermia If a patient has received multiple transfusions of banked blood preserved with citrate, which electrolyte is most likely to drop and require supplementation? - ANSWER Calcium Hypocalcemia is a concern with massive transfusion because citrate is added to banked blood to prevent coagulation. Citrate chelates (binds with) calcium, rendering it inactive. Which of the following is a possible complication of positive-pressure ventilation? - ANSWER Worsening pneumothorax Positive-pressure ventilation can lead to increased air in the chest cavity without a route of escape, worsening a pneumothorax and possibly leading to a tension pneumothorax. An intubated and sedated patient in the emergency department has multiple extremity injuries with the potential for causing compartment syndrome. What is the most reliable indication of compartment syndrome in a patient who is unconscious? - ANSWER Pressure Pressure can be assessed in the limb by palpation or direct measurement. The compartment or limb will feel tight or tense upon palpation. The skin may also appear taut and shiny. A patient arrives with a large open chest wound after being assaulted with a machete. Prehospital providers placed a nonporous dressing over the chest wound and taped it on three sides. He is now showing signs of anxiety, restlessness, severe respiratory distress, cyanosis and decreasing blood pressure. Which of the following is the MOST appropriate immediate intervention? - ANSWER Dressing removal This is the fastest effective intervention for this decompensating patient. A nonporous dressing taped on three sides is temporary and has variable effectiveness. If signs and symptoms of tension pneumothorax develop after the application of the dressing Which of the following is a component of the trauma triad of death? - ANSWER Acidosis The three components of the trauma triad of death are acidosis, hypothermia and coagulopathy. When is the tertiary survey completed for a trauma patient? - ANSWER Within 24 hours of the trauma The tertiary survey consists of a complete examination performed following the primary and secondary surveys and within 24 hours after trauma to identify any injuries missed during the initial assessment. A 36-year-old female has a deformity of the left wrist after a fall. She is reluctant to move her hand due to pain. Which of the following is the most appropriate intervention? - ANSWER Apply a splint and elevate the extremity above the level of the heart Splinting the injured extremity stabilizes the extremity and reduces further injury. Elevation above the level of the heart promotes venous return and may reduce swelling. A trauma patient is restless and repeatedly asking "Where am I?" Vital signs upon arrival were BP 110/60 mm Hg, HR 96 beats/minute and RR 24 breaths/minute. Her skin is cool and dry. Current vital signs are BP 104/84
