47 Multiple Choice Questions and Answers on Airway Management
Revise and practice with 47 comprehensive MCQ on Airway Management, featuring detailed explanations to deepen your understanding of Emergency Medical Services Quiz concepts. Perfect for quick review and exam preparation.
1 Which maneuver is recommended for opening the airway of a patient with a suspected neck injury?
The jaw-thrust maneuver opens the airway without moving the neck, reducing the risk of spinal injury.
2 What is the primary purpose of an oropharyngeal airway?
An oropharyngeal airway prevents the tongue from blocking the airway, aiding in airway patency.
3 Which device is typically used for airway management in conscious patients?
A nasopharyngeal airway is suitable for conscious patients as it causes less gagging compared to an oropharyngeal airway.
4 What is the purpose of pre-oxygenation before intubation?
Pre-oxygenation increases the oxygen reserve, delaying hypoxia during intubation.
5 Which airway management technique is used to prevent aspiration during intubation?
Cricoid pressure reduces the risk of aspiration by compressing the esophagus.
6 What is a key advantage of video laryngoscopy over direct laryngoscopy?
Video laryngoscopy provides enhanced visualization of the vocal cords, aiding intubation.
7 Why is the sniffing position recommended during intubation?
The sniffing position aligns the oral, pharyngeal, and laryngeal axes, facilitating intubation.
8 Which is a contraindication for nasotracheal intubation?
Nasotracheal intubation is contraindicated in basilar skull fractures due to the risk of intracranial penetration.
9 What complication can arise from improper use of a bag-valve-mask device?
Improper use of a bag-valve-mask can lead to gastric insufflation, increasing the risk of aspiration.
10 Which airway device is designed to sit over the laryngeal inlet?
The laryngeal mask airway sits over the laryngeal inlet, allowing ventilation without entering the trachea.
11 What is the primary indication for rapid sequence intubation (RSI)?
RSI is indicated for immediate airway protection in patients at risk of aspiration or respiratory failure.
12 Which sign indicates a potentially blocked airway?
Stridor is a high-pitched sound indicating a narrowed or blocked airway.
13 Why is humidified oxygen used in airway management?
Humidified oxygen prevents drying of the respiratory tract and secretions, improving patient comfort.
14 What is the function of a Bougie in airway management?
A Bougie acts as a guide for the insertion of the endotracheal tube in difficult intubations.
15 What is the maximum recommended duration for a single intubation attempt?
A single intubation attempt should not exceed 30 seconds to minimize the risk of hypoxia.
16 Which condition is a contraindication for using an oropharyngeal airway?
An oropharyngeal airway is contraindicated in conscious patients due to the risk of gagging.
17 Why is auscultation performed after intubation?
Auscultation confirms that both lungs are being ventilated properly, indicating correct tube placement.
18 How does CPAP assist in airway management?
CPAP provides continuous positive airway pressure, keeping airways open, especially in sleep apnea.
19 What is the main complication of over-inflating the endotracheal tube cuff?
Over-inflation of the cuff can cause tracheal damage or pressure necrosis.
20 Which technique is used to confirm endotracheal tube placement?
End-tidal CO2 monitoring confirms tube placement by detecting exhaled CO2.
21 When might an awake intubation be necessary?
Awake intubation may be necessary when sedation poses significant risks to the patient.
22 What is the purpose of a bite block during intubation?
A bite block prevents the patient from biting and damaging the endotracheal tube.
23 Which condition commonly leads to airway obstruction in children?
Children are prone to airway obstruction due to foreign body aspiration.
24 What is the role of cricoid pressure in airway management?
Cricoid pressure is applied to prevent regurgitation during intubation.
25 Why is it important to monitor oxygen saturation during airway management?
Monitoring oxygen saturation ensures adequate oxygen delivery and prevents hypoxemia.
26 How does positioning affect airway management in obese patients?
Elevating the head and shoulders improves airway alignment in obese patients.
27 What is the significance of the Mallampati score in airway assessment?
The Mallampati score predicts the difficulty of intubation based on oral cavity visualization.
28 Which device is commonly used to maintain an open airway in unconscious patients?
An oropharyngeal airway maintains an open airway by preventing the tongue from blocking the airway.
29 What is a common error in using bag-valve-mask devices?
A common error is not maintaining a proper seal over the patient's face, leading to inadequate ventilation.
30 Why is the recovery position used in unconscious patients?
The recovery position helps maintain airway patency and reduces the risk of aspiration.
31 What is the main goal of airway management in trauma patients?
The primary goal is to maintain airway patency without exacerbating injuries.
32 Which complication can arise from prolonged intubation?
Prolonged intubation can lead to tracheal stenosis or damage.
33 What is a potential risk of inserting an oropharyngeal airway in a conscious patient?
Inserting an oropharyngeal airway in a conscious patient may cause gagging and vomiting.
34 Which airway management technique is used to clear secretions from the airway?
Suctioning is used to remove secretions, blood, or vomit obstructing the airway.
35 Why is it important to check for equal chest rise during ventilation?
Checking for equal chest rise ensures that both lungs are being ventilated properly.
36 What is the main advantage of using a stylet during intubation?
A stylet provides rigidity and shape to the endotracheal tube, facilitating easier insertion.
37 Why should nasopharyngeal airways be properly sized for pediatric patients?
Proper sizing is essential to avoid trauma to the delicate airways of pediatric patients.
38 What is a key consideration when using airway adjuncts in pediatric patients?
Appropriate sizing of airway adjuncts is crucial to avoid airway trauma in pediatric patients.
39 Why is it important to document the depth of endotracheal tube placement?
Documenting the depth helps ensure correct positioning and facilitates future checks.
40 What is the purpose of using lower tidal volumes in mechanical ventilation?
Using lower tidal volumes helps prevent ventilation-induced lung injury.
41 What role do end-tidal CO2 monitors play in airway management?
End-tidal CO2 monitors confirm proper tube placement by measuring exhaled CO2.
42 How can foreign body aspiration be managed in a conscious adult?
Abdominal thrusts (Heimlich maneuver) are used to expel a foreign body in a conscious adult.
43 What is the primary advantage of video laryngoscopy?
Video laryngoscopy provides enhanced visualization of the vocal cords, aiding intubation.
44 Which maneuver should be used to open an airway without moving the neck?
The jaw-thrust maneuver opens the airway without moving the neck, reducing the risk of spinal injury.
45 What is the function of a laryngeal mask airway (LMA)?
An LMA sits over the laryngeal inlet, allowing ventilation without entering the trachea.
46 Why might a tracheostomy be preferred over intubation?
A tracheostomy is preferred for long-term airway management or when intubation is not possible.
47 What complication can arise from edema affecting airway management?
Edema narrows the airway, making ventilation more difficult.
