When using an oropharyngeal airway (OPA), the appropriate size is determined by measuring from:
Answer: The corner of the mouth to the earlobe
The correct OPA size is selected by measuring from the corner of the patient's mouth to the earlobe or the center of the mouth to the angle of the jaw.
What is the primary advantage of video laryngoscopy over direct laryngoscopy in emergency intubation?
Answer: Provides an improved glottic view, particularly in difficult airways
Video laryngoscopy improves glottic visualization and first-pass success rates, especially in patients with difficult airway anatomy.
In ACLS, passive oxygenation during cardiac arrest refers to:
Answer: Placing a non-rebreather mask on the patient with O2 flowing during CPR without active ventilation
Passive oxygenation delivers high-flow O2 via a mask to take advantage of the small tidal volumes generated by chest compressions without active ventilation.
A patient is intubated and PETCO2 suddenly drops to zero. What is the most likely cause?
Answer: Esophageal intubation or tube dislodgement
A sudden drop of PETCO2 to zero indicates no CO2 in exhaled gas, most commonly due to esophageal intubation, tube dislodgement, or circuit disconnection.
Which of the following is the recommended oxygen saturation (SpO2) target after ROSC during post-arrest care?
Answer: 94–99%
Post-ROSC oxygen therapy should target SpO2 of 94–99% to avoid both hypoxia and hyperoxia, which can worsen neurologic outcomes.
The 'sniffing position' in airway management involves:
Answer: Neck flexion and head extension to align the oral, pharyngeal, and tracheal axes
The sniffing position aligns the oral, pharyngeal, and laryngeal axes by flexing the neck and extending the head, optimizing the view for intubation.
