#1
What is the primary goal of airway management in emergency situations?
To maintain an open airway
ExplanationEnsure airway patency for adequate ventilation.
#2
Which of the following maneuvers is commonly used to open the airway in an unresponsive patient?
Head-tilt, chin-lift
ExplanationBasic technique to clear the air passage.
#3
In the context of airway management, what does the term 'RSI' stand for?
Rapid Sequence Intubation
ExplanationMethod for urgent airway control.
#4
What is the purpose of a nasopharyngeal airway (NPA) in airway management?
To maintain an open airway in unconscious patients
ExplanationMaintains airway patency without risking airway obstruction.
#5
What is the purpose of the Sellick maneuver (cricoid pressure) during intubation?
To reduce the risk of regurgitation and aspiration
ExplanationPrevents gastric contents from entering the lungs.
#6
Which of the following devices is commonly used for bag-mask ventilation during resuscitation?
Bag-valve-mask (BVM)
ExplanationCommon tool for providing positive pressure ventilation.
#7
In the context of emergency airway management, what does the acronym 'CICO' stand for?
Cannot Intubate, Cannot Operate
ExplanationDire scenario where conventional methods fail.
#8
What is the primary purpose of a supraglottic airway device (SAD) in airway management?
To provide a route for ventilation and oxygenation
ExplanationAlternative means for airway management.
#9
In the context of ventilation, what does the term 'tidal volume' refer to?
The volume of air inhaled and exhaled with each breath
ExplanationAmount of air moved during normal breathing cycle.
#10
What is the primary purpose of a cricothyroidotomy in emergency airway management?
To secure the airway in case of failure of conventional methods
ExplanationUltimate airway intervention when other methods fail.
#11
Which of the following is a potential complication of using a bag-valve-mask (BVM) during ventilation?
Hypoventilation
ExplanationRisk if ventilation is inadequate.
#12
Which of the following is a potential complication of endotracheal intubation?
Esophageal perforation
ExplanationRisk associated with the procedure.
#13
What is the purpose of positive end-expiratory pressure (PEEP) in mechanical ventilation?
To increase oxygenation
ExplanationEnhance oxygen exchange in the lungs.
#14
Which of the following is a sign of effective bag-mask ventilation during CPR?
Chest rise
ExplanationIndication of successful ventilation.
#15
What is the recommended compression-to-ventilation ratio for adult CPR?
30:2
ExplanationGuideline for effective CPR cycles.
#16
What is the role of capnography in monitoring a patient's ventilation status?
Monitoring end-tidal carbon dioxide (EtCO2)
ExplanationIndicates adequacy of ventilation.
#17
When using a laryngeal mask airway (LMA), where is the mask typically positioned?
Over the trachea
ExplanationEnsures airway access above the trachea.
