TNCC Airway Management 2

Question 1

Which anatomical landmark is used to confirm correct endotracheal tube placement above the carina?

Accepted Answer

Carina at T4-T5

Answer

The carina, located at the level of T4-T5, is the bifurcation point; the ETT tip should rest 2-3 cm above it.

Question 2

A trauma patient has a suspected cervical spine injury and requires intubation. Which technique best maintains spinal immobilization?

Accepted Answer

Video laryngoscopy with manual in-line stabilization

Answer

Video laryngoscopy combined with manual in-line stabilization allows intubation while minimizing cervical spine movement.

Question 3

What is the primary indication for performing a needle cricothyrotomy in a trauma patient?

Accepted Answer

Cannot intubate, cannot oxygenate scenario with no other airway access

Answer

Needle cricothyrotomy is a rescue technique reserved for the 'can't intubate, can't oxygenate' emergency when other airway methods have failed.

Question 4

Which waveform capnography finding most reliably confirms endotracheal tube placement in the trachea?

Accepted Answer

Persistent rectangular CO2 waveform over multiple breaths

Answer

A consistent rectangular capnography waveform across multiple ventilations is the gold standard for confirming tracheal intubation.

Question 5

A patient with a stab wound to the neck presents with subcutaneous emphysema and stridor. The MOST appropriate initial airway intervention is:

Accepted Answer

Early definitive airway before edema occludes the airway

Answer

Expanding neck hematoma or tracheal injury can rapidly occlude the airway; early definitive airway securement is critical before complete obstruction occurs.
