#1
What is the purpose of a Yankauer suction tip in airway management?
To clear secretions from the oral cavity
ExplanationUsed to suction secretions from the oral cavity, facilitating airway clearance.
#2
Which of the following is a common indication for endotracheal intubation?
Severe respiratory distress
ExplanationIndicated in severe respiratory distress to secure airway and assist ventilation.
#3
During bag-mask ventilation, what is the recommended rate of ventilations for an adult patient?
20-24 breaths per minute
ExplanationMaintains adequate oxygenation, typically recommended at 20-24 breaths per minute.
#4
What is the purpose of a tracheostomy tube in airway management?
To bypass upper airway obstruction
ExplanationProvides a direct airway bypassing upper airway obstructions, ensuring ventilation.
#5
What is the primary purpose of the cuff on an endotracheal tube?
To prevent air leakage
ExplanationCreates a seal between the tube and trachea, preventing air leakage and aspiration.
#6
In airway management, what is the purpose of using a laryngeal mask airway (LMA)?
To provide a patent airway without intubation
ExplanationOffers a non-invasive means of securing the airway, useful when intubation is not feasible.
#7
In suctioning techniques, what is the recommended suction pressure for adult patients?
50-80 mmHg
ExplanationBalances effective secretion removal with minimal risk of mucosal damage, typically set at 50-80 mmHg.
#8
In suctioning techniques, what is the purpose of hyperinflating the cuff of an endotracheal tube before suctioning?
To protect the airway
ExplanationCreates a seal, preventing aspiration of secretions into the lower airway during suctioning.
#9
Which of the following is a potential complication of suctioning an artificial airway?
Bradycardia
ExplanationStimulation of the vagus nerve during suctioning can lead to bradycardia.
#10
Which suctioning technique is recommended for removing thick and tenacious secretions?
Deep suctioning
ExplanationEffective for thick secretions, reaching deeper into the airway for removal.
#11
Which of the following is a potential complication of prolonged intubation?
Increased risk of infection
ExplanationProlonged intubation increases the risk of ventilator-associated pneumonia and other infections.
#12
What is the primary purpose of using a stylet during endotracheal tube insertion?
To guide the tube through the vocal cords
ExplanationFacilitates easier insertion by providing rigidity to the tube, aiding passage through the vocal cords.
#13
Which of the following is a potential complication of using a too-large endotracheal tube?
Increased airway resistance
ExplanationA too-large tube can cause increased airway resistance, compromising ventilation.
