                      問題 #46
                      Witnesses state a patient is unresponsive and not breathing after a vehicle collision. What action should the EMT perform first?

                      答案：D

                      解題說明：
                      Even in high-acuity situations, NREMT standards require EMTs to perform a scene size-up before patient contact. Scene size-up includes ensuring scene safety, determining the mechanism of injury, identifying hazards, and assessing the need for additional resources. Entering a scene without confirming safety places the EMT at risk and can result in additional victims.
                      Although the patient is unresponsive and apneic, EMTs must first confirm the scene is safe to enter. Only after scene safety is established should patient care begin.
                      Option B is incorrect because CPR cannot be initiated until the EMT has safely accessed the patient.
                      Option C is incorrect because airway maneuvers are performed after scene safety and patient access are confirmed.
                      Option D is incorrect because spinal stabilization occurs after initial access and assessment.
                      NREMT emphasizes: rescuer safety always comes first, even in life-threatening emergencies.


                      問題 #47
                      Following insertion of an oropharyngeal airway in an unresponsive 1-year-old male, he develops cyanosis and bradycardia. You should

                      答案：A

                      解題說明：
                      The correct answer is A. Remove the airway and ventilate him.
                      In pediatric patients, improper placement or incorrect sizing of an oropharyngeal airway (OPA) can cause:
                      * Airway obstruction instead of opening
                      * Worsening hypoxia
                      * Leading to cyanosis and bradycardia
                      * The patient's cyanosis (low oxygen) and bradycardia (late hypoxia sign) indicate that the airway intervention has failed or worsened the situation.
                      * Immediate action is to:
                      * Remove the OPA
                      * Provide effective ventilations with BVM
                      * B. Continue ventilation with the airway in place # Incorrect because the airway is likely malpositioned or obstructing airflow
                      * C. Increase ventilation rate to 40-60 # Excessive and inappropriate; does not correct obstruction
                      * D. Start CPR if HR < 100 # In pediatrics, CPR begins if HR < 60 with poor perfusion, not < 100
                      * "If an airway adjunct worsens ventilation, it should be removed immediately."
                      * "Bradycardia in infants is a sign of hypoxia."
                      * "Ensure adequate ventilation before initiating compressions."

                      問題 #48
                      Which of the following injuries occurs when the epidermis is damaged by a scraping force?

                      答案：D

                      解題說明：
                      The correct answer is B. Abrasion.
                      An abrasion is a superficial injury caused by scraping or rubbing force that damages the epidermis (outer layer of skin). This type of injury is commonly referred to as a "scrape" or "road rash." Why B is correct:
                      * Abrasions occur when the skin is rubbed or scraped against a rough surface.
                      * They involve only the epidermis and are usually superficial.
                      * Minimal bleeding may occur, but the main concern is pain and risk of infection.
                      Why the other options are incorrect:
                      * A. Avulsion # Involves tearing away of skin or tissue, often deeper and more severe
                      * C. Puncture # Caused by a sharp, pointed object penetrating the skin
                      * D. Laceration # A cut or tear in the skin, typically deeper than an abrasion Exact Extracts:
                      * "An abrasion is a wound caused by scraping or rubbing of the skin."
                      * "It involves damage to the epidermis."
                      * "Abrasions are usually superficial but can be painful and prone to infection." References:

                      問題 #49
                      An 83-year-old patient is unresponsive and lying on the floor. The patient has a large bruise and laceration on the forehead. The patient's vital signs are BP 90/60 mmHg, P 126/min, and R 0. Which of the following conditions should the EMT most suspect?

                      答案：A

                      解題說明：
                      This patient presents with severe head trauma, unresponsiveness, hypotension, tachycardia, and apnea (R =
                      0). NREMT education stresses that apnea following head injury is a critical red flag for increased intracranial pressure (ICP) and potential brain herniation.
                      Option B is correct because brain herniation occurs when swelling or bleeding within the skull forces brain tissue downward, compressing the brainstem. Compression of the brainstem can result in loss of respiratory drive, explaining the absence of respirations. Elderly patients are at increased risk due to cerebral atrophy and fragile bridging veins.
                      Option A is possible but does not directly explain apnea.
                      Option C is associated with sudden cardiac arrest after chest impact, not head trauma.
                      Option D would present with respiratory compromise but not directly from a forehead injury.
                      NREMT emphasizes rapid airway management, ventilation, spinal precautions, and immediate transport for suspected brain herniation.


                      問題 #50
                      A 3-year-old patient ingested laundry detergent. The patient is drowsy and has crackles in all lung fields. What should most concern the EMT at this time? Select the three answer options that are correct.

                      答案：B,C,D

                      解題說明：
                      Comprehensive and Detailed Explanation From Exact Extract:
                      Laundry detergent ingestion - especially in the case ofliquid detergent pods- is associated withcaustic airway and gastrointestinal injuries. The presence ofcracklesanddrowsinessare signs of aspiration and possiblerespiratory failure. Vomiting increases the risk ofaspiration pneumonitis, andesophageal perforationis a life-threatening complication from corrosive ingestion.
                      While seizure and hypoglycemia are possible complications of toxic ingestion, they are not as immediately linked to the detergent profile as airway injury and aspiration risk.
