#1
Which of the following is a primary indication for the use of a nasopharyngeal airway?
Treatment of upper airway obstruction
ExplanationNasopharyngeal airways are used to treat upper airway obstruction by providing a clear passage for airflow.
#2
During bag-valve-mask ventilation, proper technique includes:
Allowing the chest to fully recoil between breaths
ExplanationAllowing the chest to fully recoil between breaths ensures effective ventilation and prevents air trapping.
#3
Which of the following is a complication associated with prolonged nasotracheal intubation?
Development of sinusitis or nasal septal necrosis
ExplanationProlonged nasotracheal intubation can lead to complications such as sinusitis or nasal septal necrosis due to mucosal irritation and pressure on nasal structures.
#4
What is the primary goal of airway management in a trauma patient?
To maintain oxygenation and ventilation
ExplanationIn trauma patients, the primary goal of airway management is to ensure adequate oxygenation and ventilation to prevent hypoxia and respiratory compromise.
#5
Which of the following is a characteristic of a supraglottic airway device?
It is commonly used as a primary airway device in advanced airway management
ExplanationSupraglottic airway devices are frequently used as primary airway devices in advanced airway management due to their ease of insertion and reliability.
#6
What is the primary purpose of cricoid pressure during intubation?
To occlude the esophagus and reduce the risk of regurgitation
ExplanationCricoid pressure is applied to occlude the esophagus, reducing the risk of gastric regurgitation and aspiration during intubation.
#7
Which of the following is a contraindication for the use of a supraglottic airway device?
Facial trauma with disruption of airway anatomy
ExplanationFacial trauma with disruption of airway anatomy can hinder proper placement and function of supraglottic airway devices, making them contraindicated in such cases.
#8
Which of the following techniques is commonly used to manage a difficult airway?
Rapid sequence induction with succinylcholine
ExplanationRapid sequence induction with succinylcholine is a common technique used to manage a difficult airway by rapidly inducing unconsciousness and paralysis to facilitate intubation.
