Certified Registered Nurse Anesthetist (CRNA) Practice Exam

Which of the following methods can assist with airway management during anesthesia?

1. Tracheostomy only

2. Continuous positive airway pressure (CPAP) only

3. Bag-mask ventilation and endotracheal intubation

4. Only non-invasive ventilation

The correct answer is: Bag-mask ventilation and endotracheal intubation

The choice of bag-mask ventilation and endotracheal intubation is significant for effective airway management during anesthesia. Bag-mask ventilation allows for the delivery of oxygen to patients with compromised airway patency and can be used as a first-line approach for securing an airway, especially in situations where a patient may not be able to ventilate adequately on their own. Endotracheal intubation is another essential technique that provides a secure airway, ensuring that the airway is protected against aspiration and allowing for controlled ventilation. In the context of anesthesia, intubation is often necessary when general anesthesia is administered to maintain a patent airway and ensure effective gas exchange. Both techniques work together to enhance patient safety and oxygenation, especially in emergencies or during surgical procedures where the patient’s reflexes might be diminished. Thus, the combination of bag-mask ventilation and endotracheal intubation represents a comprehensive approach to managing the airway effectively during different phases of anesthesia.
