DAANCE Airway Management and Oxygen Therapy 2

Question 1

The jaw thrust maneuver is the preferred technique for opening the airway in a patient with a suspected:

Accepted Answer

Cervical spine injury

Answer

The jaw thrust opens the airway by displacing the mandible anteriorly without extending or rotating the neck, making it safe when cervical spine injury is a concern.

Question 2

Partial laryngospasm is most commonly identified by:

Accepted Answer

A high-pitched crowing or stridor sound

Answer

Partial laryngospasm produces stridor or high-pitched crowing because air moves through a narrowed but not fully closed glottis.

Question 3

What is the first-line intervention for mild laryngospasm during office-based sedation?

Accepted Answer

Apply positive-pressure ventilation with 100% oxygen and jaw thrust

Answer

Positive-pressure ventilation with 100% O2 combined with jaw thrust is the least invasive initial step and often successfully breaks mild laryngospasm.

Question 4

How is the correct size for an oropharyngeal airway (OPA) determined in an adult?

Accepted Answer

From the corner of the mouth to the angle of the mandible

Answer

An OPA is correctly sized by measuring from the corner of the mouth to the angle of the mandible, ensuring it reaches from the lips to the base of the tongue.

Question 5

How is the correct size for a nasopharyngeal airway (NPA) determined?

Accepted Answer

From the tip of the nose to the earlobe

Answer

Measuring from the tip of the nose to the earlobe provides the appropriate NPA length to position the tip at the nasopharynx without entering the larynx.
