All flashcards
Flashcard 1: Identify the preferred airway positioning maneuver for an adult without suspected spinal injury.
Answer: Head tilt–chin lift. This maneuver extends the neck and lifts the chin to align oral, pharyngeal, and tracheal axes for optimal airflow.
Flashcard 2: What is the primary purpose of an airway adjunct such as an OPA or NPA?
Answer: Maintain airway patency by preventing tongue obstruction. These adjuncts displace the tongue anteriorly to ensure an open pathway for air exchange in compromised patients.
Flashcard 3: What is the correct OPA insertion technique for an adult to avoid pushing the tongue posteriorly?
Answer: Insert upside down, rotate 180∘ as it advances. Inserting inverted and rotating follows the palate's curve, preventing the tongue from being pushed back into the airway.
Flashcard 4: Which OPA insertion technique is preferred for infants and small children?
Answer: Insert with tongue depressor; do not rotate. Using a tongue depressor allows direct, non-rotational insertion to avoid trauma in smaller pediatric airways.
Flashcard 5: What is the most appropriate immediate action if you cannot ventilate effectively after supraglottic placement?
Answer: Remove device and ventilate with BVM. Immediate removal and BVM use restores basic ventilation when supraglottic device fails to provide adequate oxygenation.
Flashcard 6: What is the correct immediate action if significant resistance is met during NPA insertion?
Answer: Remove and attempt the other nare. Switching nares avoids forcing insertion, which could cause trauma or epistaxis if resistance indicates obstruction.
Flashcard 7: Which device is most appropriate to provide a conduit for suctioning and BVM ventilation in an unconscious patient with no gag?
Answer: Oropharyngeal airway (OPA). OPA maintains oropharyngeal patency in unconscious patients, facilitating suction and bag-valve-mask ventilation.
Flashcard 8: What complication is most associated with NPA placement in anticoagulated patients?
Answer: Epistaxis (nasal bleeding). Anticoagulated patients are prone to bleeding from nasal mucosa disruption during NPA insertion.
Flashcard 9: What is the correct action if a patient with an OPA develops gagging during ventilation?
Answer: Remove the OPA immediately. Prompt removal eliminates the stimulus causing gagging, preventing potential vomiting or laryngospasm during ventilation.
Flashcard 10: Identify the most common clinical sign that a supraglottic airway is malpositioned.
Answer: Significant air leak with poor chest rise. Malposition prevents proper seal, resulting in air escaping and inadequate lung inflation during ventilation attempts.
Flashcard 11: Which direction should the bevel face during NPA insertion to reduce turbinate trauma?
Answer: Bevel toward the septum. Facing the bevel medially aligns it with the nasal septum, minimizing trauma to the lateral turbinates during advancement.
Flashcard 12: What is the correct NPA sizing method using external landmarks?
Answer: Nose tip (nares) to earlobe (tragus). This landmark measurement confirms appropriate NPA length to reach from nostril to nasopharynx without excessive protrusion.
Flashcard 13: What is the correct OPA sizing method using external landmarks?
Answer: Mouth corner to earlobe (angle of mandible). This measurement ensures the OPA length matches the distance from lips to the angle of the jaw for proper pharyngeal positioning.
Flashcard 14: Which patient condition is the most appropriate indication for a supraglottic airway device?
Answer: Apneic or inadequate respirations needing ventilatory support. Supraglottic devices provide advanced ventilatory support for apneic patients when basic methods are insufficient.
Flashcard 15: Which airway adjunct is preferred when the patient has an intact gag reflex or is semi-conscious?
Answer: Nasopharyngeal airway (NPA). Preferred for patients with intact gag reflex as it is inserted nasally, bypassing oral structures that could trigger gagging.
Flashcard 16: What complication is most associated with placing an OPA in a patient with a gag reflex?
Answer: Vomiting and aspiration. OPA insertion in patients with gag reflex stimulates retching, increasing risk of emesis and pulmonary aspiration.
Flashcard 17: Identify the preferred airway maneuver when spinal injury is suspected and the airway must be opened.
Answer: Jaw-thrust maneuver. Displaces the mandible forward without cervical extension, minimizing risk of exacerbating spinal cord injury.
Flashcard 18: Identify the classic contraindication to NPA insertion for AEMT testing.
Answer: Suspected basilar skull fracture. Basilar skull fractures risk NPA entering the cranial cavity through the cribriform plate, potentially causing severe complications.
Flashcard 19: Which option best describes a key limitation of supraglottic airways compared with endotracheal tubes?
Answer: They do not definitively protect against aspiration. Unlike endotracheal tubes, supraglottic devices do not isolate the trachea, allowing potential regurgitation into the lungs.
Flashcard 20: Which finding is the best indicator that ventilation through a supraglottic airway is effective?
Answer: Sustained waveform capnography (ETCO2) with chest rise. Waveform capnography confirms CO2 expulsion, while chest rise verifies effective air delivery to the lungs.
Flashcard 21: Which patient scenario is a contraindication to supraglottic airway use in many protocols?
Answer: Known caustic ingestion or major airway obstruction. Caustic ingestion risks further tissue damage, and major obstruction may prevent proper device seating or ventilation.
Flashcard 22: Which airway device sits above the vocal cords and does not require laryngoscopy?
Answer: Supraglottic airway device. Positioned above the glottis, these devices allow blind insertion without need for vocal cord visualization.
Flashcard 23: Identify the primary contraindication to OPA placement.
Answer: Intact gag reflex (responsive patient). An intact gag reflex in responsive patients can lead to vomiting, laryngospasm, or aspiration upon OPA insertion.
Flashcard 24: Which airway adjunct is indicated for an unresponsive patient with no gag reflex?
Answer: Oropharyngeal airway (OPA). Indicated for unresponsive patients without gag reflex to prevent tongue from obstructing the posterior pharynx and maintain airway patency.
