AEMT Chapter 4: Airway Management and Ventilation| Advanced Q&A 2025| Latest Release The nasal cavity serves multiple purposes in the respiratory system. Which of the following is a primary function of the nasal passages in airway anatomy? The nasal passages filter, warm, and humidify the air as it enters the respiratory system. In airway assessment, which sign often indicates the presence of a compromised airway? Stridor or snoring respirations are commonly indicative of airway obstruction or narrowing. During the assessment of a patient’s airway, which of these should be considered the most critical finding? Inability to speak or cough suggests a complete airway obstruction and requires immediate intervention. When utilizing a head-tilt, chin-lift maneuver, which aspect of airway management is being addressed? The maneuver aims to clear the airway by repositioning the tongue to prevent airway obstruction. In cases of suspected airway obstruction in an adult patient, which technique should be used as an initial approach to remove the obstruction? 2 Performing abdominal thrusts (Heimlich maneuver) is typically the first step in clearing an airway obstruction. Ventilating a patient with a bag-valve mask involves a specific technique. What is the ideal approach when using this tool? The mask should form a tight seal over the patient's nose and mouth while providing adequate ventilation without excessive pressure. When managing a patient in respiratory distress, which method of oxygen administration is often the most appropriate for initial oxygenation? A non-rebreather mask is typically used for patients requiring high concentrations of oxygen. A patient with a suspected severe head injury is in need of airway management. Which advanced technique should be considered for maintaining the airway? Endotracheal intubation may be necessary to ensure a secure airway in patients with compromised consciousness or severe head injury. In cases of failed endotracheal intubation, what is the next step in airway management? Insertion of a supraglottic airway device (e.g., Laryngeal Mask Airway) can provide an alternative airway if intubation is unsuccessful. When using a needle to perform a cricothyrotomy, what complication can arise that requires caution? 3 The risk of injury to surrounding structures, such as the trachea or blood vessels, is a concern when performing a cricothyrotomy. Ventilation during resuscitation efforts is essential for oxygenation. Which of the following would likely reduce the effectiveness of ventilations? Inadequate seal of the mask or improper head positioning can hinder ventilation and reduce oxygen delivery. In a trauma patient, what special consideration is important when attempting to manage the airway? Cervical spine precautions should be taken to avoid aggravating a potential spinal injury when positioning the head and neck. For a patient who is unconscious and not breathing, which action is critical in airway management? Immediate placement of an airway adjunct such as an or
