Read the first 7 Airway Management and Respiratory Emergencies flashcards as text

  1. Which laryngoscope blade is most appropriate for a patient with a suspected anterior (anterior larynx) and with an omega-shaped epiglottis?

    Answer: Miller (straight) blade

    The Miller straight blade is preferred for patients with an anterior airway or a floppy omega-shaped epiglottis because it directly lifts the epiglottis to expose the cords.

  2. You are ventilating a patient with a BVM and notice gastric distension developing. What is the BEST intervention to reduce aspiration risk while continuing ventilation?

    Answer: Apply cricoid pressure (Sellick maneuver)

    Cricoid pressure compresses the esophagus against the cervical vertebrae, reducing passive regurgitation during BVM ventilation when airway is not secured.

  3. A patient with suspected anaphylaxis presents with stridor, hoarse voice, and rapidly developing angioedema. What airway management approach is MOST appropriate?

    Answer: Perform rapid sequence intubation (RSI) early before the airway completely obstructs

    Early RSI is indicated because angioedema can rapidly progress to complete obstruction, making intubation impossible and surgical airway the only option if delayed.

  4. Which of the following is the MOST appropriate initial approach to managing a pediatric patient with croup (laryngotracheobronchitis) exhibiting moderate respiratory distress?

    Answer: Nebulized epinephrine and corticosteroids

    Nebulized epinephrine reduces subglottic edema and corticosteroids reduce airway inflammation, making them first-line treatment for moderate croup.

  5. During RSI, succinylcholine is contraindicated in which of the following clinical situations?

    Answer: Patient with a history of malignant hyperthermia or crush injury

    Succinylcholine is contraindicated in crush injuries (hyperkalemia risk causing cardiac arrest) and in patients with or at risk for malignant hyperthermia due to potentially fatal muscle rigidity.

  6. A patient presents with sudden onset pleuritic chest pain and dyspnea after a long flight. SpO2 is 91%, heart rate 118, respiratory rate 24. Lung sounds are clear bilaterally. What is the MOST likely diagnosis?

    Answer: Pulmonary embolism

    Prolonged immobility (long flight), sudden pleuritic chest pain, tachycardia, tachypnea, hypoxia with clear lungs, and no trauma strongly suggests pulmonary embolism.

  7. What is the MOST important consideration when using a King LT (supraglottic airway) as a rescue airway device?

    Answer: It does not protect against aspiration in a patient with a full stomach

    Supraglottic airways like the King LT do not provide the same protection against aspiration as a cuffed endotracheal tube, which is critical to recognize in patients at risk.
