ACLS ACLS Airway Management 3

Question 1

When using an oropharyngeal airway (OPA), the appropriate size is determined by measuring from:

Accepted Answer

The corner of the mouth to the earlobe

Answer

The tip of the nose to the earlobe

Answer

The center of the lips to the angle of the jaw

Answer

The upper lip to the chin

Question 2

What is the primary advantage of video laryngoscopy over direct laryngoscopy in emergency intubation?

Accepted Answer

Provides an improved glottic view, particularly in difficult airways

Answer

Eliminates the need for preoxygenation

Answer

Removes the risk of esophageal intubation entirely

Answer

Requires less training and can be used without experience

Question 3

In ACLS, passive oxygenation during cardiac arrest refers to:

Accepted Answer

Placing a non-rebreather mask on the patient with O2 flowing during CPR without active ventilation

Answer

Using high-flow O2 via bag-mask at 30 breaths per minute

Answer

Applying O2 only after ROSC is confirmed

Answer

Running O2 through a nasal cannula at 2 L/min

Question 4

A patient is intubated and PETCO2 suddenly drops to zero. What is the most likely cause?

Accepted Answer

Esophageal intubation or tube dislodgement

Answer

Successful ROSC

Answer

Equipment malfunction only

Answer

Patient is hyperventilating

Question 5

Which of the following is the recommended oxygen saturation (SpO2) target after ROSC during post-arrest care?

Accepted Answer

94–99%

Answer

100% (maximum oxygenation)

Answer

88–92%

Answer

Greater than 80%

Question 6

The 'sniffing position' in airway management involves:

Accepted Answer

Neck flexion and head extension to align the oral, pharyngeal, and tracheal axes

Answer

Full head extension with no neck flexion

Answer

Neutral head position with jaw thrust only

Answer

Head turned to the side to prevent aspiration
