A 22-year-old college football player was struck in the head during a game and briefly lost consciousness. He is now awake, oriented, and reporting headache and a foggy feeling. CT of the head is negative. Which injury pattern is most consistent with this presentation?

A 35-year-old motorcyclist arrives after a high-speed collision. She was unconscious at the scene and remains in a coma (GCS 6). CT shows no significant intracranial hemorrhage, but MRI reveals punctate white matter lesions at the corpus callosum and brainstem. Which injury type is most likely?

A 48-year-old restrained driver was involved in a moderate-speed motor vehicle crash. Initial GCS was 14, declining to 11 over 2 hours. CT shows a hyperdense area at the left temporal lobe with surrounding edema and local mass effect. Which diagnosis best fits this clinical and radiographic picture?

A 45-year-old restrained driver is brought in after a high-speed motor vehicle collision. He reports left-sided chest pain that worsens with deep breathing. Chest X-ray reveals fractures of ribs 4 through 7 on the left. Which finding is the most reliable indicator of pain-related ventilatory compromise in this patient?

A 72-year-old woman with osteoporosis fell from standing height and is now complaining of anterior chest pain. She has point tenderness over the sternum and mild dyspnea. Her ECG shows sinus tachycardia. Which immediate nursing action takes highest priority?

A 58-year-old unrestrained passenger sustains blunt chest trauma in a rollover crash. On assessment, you observe a segment of the right chest wall moving inward during inspiration and outward during expiration. His respiratory rate is 28 per minute and SpO2 is 88 percent on a 15 L non-rebreather mask. What is the definitive management for this patient’s ventilatory failure?

A patient with a tibial shaft fracture reports severe pain that is disproportionate to the injury and worsens significantly with passive stretch of the muscles in the involved compartment. The nurse notes the anterior compartment feels tense. Which action is the priority?

A patient sustains a crush injury to the forearm and develops compartment syndrome. Fasciotomy is performed. On the first postoperative day, the nurse notes the wound edges are separating and the exposed muscle appears pale. Which finding most accurately indicates that perfusion has been restored to the forearm?

A young adult cyclist struck by a vehicle has a splinted right leg. Compartment pressures are anterior 38 mmHg and lateral 22 mmHg. Blood pressure is 88/54 mmHg. Using the delta pressure concept, which statement correctly guides the decision for fasciotomy?

An 82-year-old patient on warfarin presents after a low-energy ground-level fall. The initial CT of the head is negative and the patient is neurologically intact. Which statement best reflects current evidence-based management of this patient?

A 78-year-old patient taking rivaroxaban arrives after a motor vehicle collision with injuries suggesting moderate trauma. The trauma nurse anticipates which concern specific to this anticoagulant compared with warfarin?

A frail 85-year-old patient involved in a low-speed pedestrian collision has a blood pressure of 120/78 mmHg and a heart rate of 74 beats per minute. Despite vital signs within normal ranges, the trauma nurse recognizes the patient may be in occult shock for which physiologic reason?

A trauma nurse is performing a primary survey on a patient who arrived after a motor vehicle collision. The patient has a Glasgow Coma Scale score of 8, labored respirations, and a blood pressure of 88/60 mmHg. Following the ABCDE sequence, which intervention takes priority?

During the primary survey of a trauma patient, the nurse notes absent breath sounds on the left side, tracheal deviation to the right, hypotension, and distended neck veins. Which condition does this presentation most likely represent?

A 35-year-old male arrives after a stabbing to the chest. During the primary survey he is conscious, oxygen saturation is 91% on 15 L/min via non-rebreather mask, and breath sounds are equal bilaterally. The nurse notes a 2 cm sucking chest wound. Which intervention is the immediate priority?

During a mass casualty incident (MCI), the START triage system categorizes an adult who is breathing at 24 breaths per minute, has a present radial pulse, and is able to follow simple commands but cannot walk. Which triage color is assigned?

A regional hospital activates its emergency operations plan after a multi-vehicle highway crash produces 40 casualties. The incident commander directs that the trauma bay be cleared of all non-critical patients to make room for incoming injured. Which principle of hospital-based MCI response does this action reflect?

An industrial explosion produces 80 casualties. Fifteen minutes into triage, the trauma nurse notices that five patients initially tagged Delayed (Yellow) now have absent radial pulses and altered consciousness. Which action BEST reflects MCI triage principles?
