TNCC ENA 9th Edition Pre Test 2025| Actual Certified Q&A For Guaranteed Success A patient arrives at the emergency department by private vehicle after sustaining an injury to the right lower extremity while using a saw. There is a large gaping wound to the right thigh area with significant bleeding. What is the priority intervention? A. Elevate the extremity to the level of the heart B. Initiate direct pressure C. Apply a tourniquet D. Cover the open wound with sterile saline dressings - CORRECT ANSB. Initiate direct pressure Rationale: The first step inn controlling any bleeding is application of direct pressure. What technique is most appropriate when obtaining a history from a patient who has experienced a sexual assault? Following a bomb explosion, fragmentation injuries from the bomb or objects in the environment are examples of which phase of injury? A. Primary B. Secondary 2 | P a g e C. Tertiary D. Quaternary - CORRECT ANSB. Secondary Rationale: The secondary phase of a blast results from flying debris, projectiles, and bomb fragments causing lacerations or penetrating injuries. An adult patient with a knife injury to the neck has an intact airway and is hemodynamically stable. They complain of difficulty swallowing and speaking. In the primary survey, further assessment is indicated next for which of the following conditions? A. Damage to the cervical spine B. An expanding pneumothorax C. Laceration of the carotid artery D. Injury of the thyroid gland - CORRECT ANSA. Damage to the cervical spine Rationale: Penetrating neck trauma may include concurrent injuries to the cervical spine and cord, airway, or vascular neck structures. With an intact airway and hemodynamic stability, the other common concurrent injury is to the cervical spine. What is the best position for maintaining an open airway in the obese patient? 3 | P a g e A. Prone B. Supine C. Reverse Trendelenburg D. Right lateral recumbent - CORRECT ANSC. Reverse Trendelenburg Rationale: The reverse Trendelenburg position will benefit both airway maintenance and work of breathing in the obese patient. What is the leading cause of preventable death for the trauma patient in the prehospital environment? A. Airway compromise B. Ineffective ventilation C. Secondary head injury D. Uncontrolled external hemorrhage - CORRECT ANSD. Uncontrolled external hemorrhage Rationale: Uncontrolled external hemorrhage is the leading cause of preventable death after injury in the prehospital environment; assessment to identify uncontrolled external hemorrhage is key to the initial assessment process, beginning with the general impression. 4 | P a g e The general impression step in the initial assessment provides the opportunity to do which of the following? A. Assess for uncontrolled internal hemorrhage B. Accurately triage the patient C. Reprioritize circulation before airway or breathing D. Activate the trauma team - CORRECT ANSC. Reprioritize circulation before airway or breathing Rationale: The general impression is formed 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. Treatment for frostbite can include which of the following interventions? A. Warm the affected part over 30 to 60 minutes B. Use gentle friction to improve circulation C. Administer tissue plasminogen activator D. Drainage of all large and small blisters - CORRECT ANSC. Administer tissue plasminogen activator Rationale: With frostbite, thrombus formation is a risk. Tissue plasminogen activator, a thrombolytic medication, has been effective in maintaining perfusion and decreasing the need for amputation when administered within 24 hours of rewarming. 5 | P a g e A patient involved in a MVC has sustained a fracture to the second rib of the anterior left chest. Which concurrent injury is most commonly associated with this fracture? A. Blunt cardiac injury B. Brachial plexus injury C. Pneumothorax D. Hemothorax - CORRECT ANSB. Brachial plexus injury Rationale: First and second rib fractures are most commonly associated with great vessel, head and spinal cord, and brachial plexus injuries. Understanding the kinematic concepts associated with the mechanism of injury and energy transfer can initially assist the trauma care provider in which of the following? A. Anticipating the types of injuries that may be present B. Deciding whether law enforcement should be notified C. Determining needed laboratory tests D. Predicting the need for a surgical procedure - CORRECT ANSA. Anticipating the types of injuries that may be present 6 | P a g e Rationale: Mechanism of injury and energy transfer can assist the provider in anticipating and evaluating the types of injuries that may be present and their severity. A patient fell two weeks ago, striking their head. Today, the patient presented with a persistent headache and nausea and was diagnosed with a small subdural hematoma. The patient has been in the ED for 24 hours awaiting an inpatient bed. The night shift nurse reports the patient has been anxious, restless, shaky, and vomited twice during the night. The patient states they couldn't sleep because a young child kept coming into the room. What is the most likely cause for these signs and symptoms? A. Increased intracranial pressure B. Alcohol withdrawal C. Rhabdomyolysis D. Pulmonary embolus - CORRECT ANSB. Alcohol withdrawal Rationale: Alcohol withdrawal is a common delayed condition because symptoms are difficult to identify early. Signs include autonomic hyperactivity, hand tremors, nausea or vomiting, psychomotor agitation, anxiety, insomnia, transient hallucinations, or seizures. 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 7 | P a g e represents the highest priority for ongoing assessment and management for this patient? A. Maintain adequate respiratory status B. Administer balanced resuscitation fluid C. Perform serial assessments of neurologic function D. Maintain core temperature - CORRECT ANSA. Maintain 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. Maintenance of respiratory function is the highest priority.
