#1
Which of the following is not a sign of respiratory distress?
Bradypnea
ExplanationSlow breathing rate, unlike the rapid breathing typically seen in respiratory distress.
#2
What is the primary goal of emergency airway management?
To maintain oxygenation and ventilation
ExplanationEnsuring the patient continues to breathe adequately and receive enough oxygen.
#3
Which of the following is NOT a common cause of upper airway obstruction?
Pneumothorax
ExplanationA pneumothorax affects the lungs, not the upper airway.
#4
What is the recommended technique for opening the airway in an unconscious patient?
Jaw thrust
ExplanationA method of lifting the tongue and opening the airway without tilting the head.
#5
Which of the following is a characteristic feature of impending respiratory failure?
Increased respiratory rate
ExplanationThe body's attempt to compensate for inadequate oxygenation or ventilation.
#6
What is the primary cause of acute respiratory distress syndrome (ARDS)?
Sepsis
ExplanationA systemic infection leading to widespread inflammation and lung injury.
#7
Which of the following is NOT a common cause of stridor?
Pneumonia
ExplanationStridor typically arises from upper airway obstruction, not lower respiratory infections like pneumonia.
#8
What is the primary treatment for anaphylaxis-induced upper airway obstruction?
Epinephrine
ExplanationA medication used to reverse the effects of an allergic reaction and alleviate airway constriction.
#9
Which of the following is not an indication for endotracheal intubation?
Surgical airway
ExplanationEndotracheal intubation is not typically done for establishing a surgical airway.
#10
What is the preferred method to confirm endotracheal tube placement?
Capnography
ExplanationMonitoring carbon dioxide levels in exhaled breath to confirm proper placement.
#11
Which of the following is a characteristic feature of a 'can't intubate, can't oxygenate' scenario?
Inability to insert an endotracheal tube
ExplanationWhen attempts to intubate the trachea fail and oxygenation cannot be achieved.
#12
What is the purpose of a bougie in difficult airway management?
To guide the endotracheal tube into the trachea
ExplanationA tool used to assist in navigating the endotracheal tube into the trachea during difficult intubations.
#13
Which of the following is an indication for the use of non-invasive positive pressure ventilation (NIPPV)?
Acute exacerbation of COPD
ExplanationA condition where NIPPV is commonly used to support breathing.
#14
What is the purpose of a cricoid pressure during endotracheal intubation?
To reduce the risk of aspiration
ExplanationApplying pressure to the cricoid cartilage to prevent regurgitation of stomach contents into the lungs.
#15
Which of the following is NOT a risk factor for difficult airway management?
Young age
ExplanationYounger patients generally have more easily managed airways.
#16
What is the primary mechanism of action of continuous positive airway pressure (CPAP)?
Recruiting collapsed alveoli
ExplanationApplying positive pressure to keep the small air sacs in the lungs open.
#17
Which of the following is a common sign of impending respiratory arrest?
Decreased level of consciousness
ExplanationA neurological manifestation indicating worsening oxygenation and ventilation.
#18
What is the most appropriate initial intervention for a patient with severe upper airway obstruction?
Heimlich maneuver
ExplanationA technique to dislodge obstructing objects from the airway by applying abdominal pressure.
#19
Which of the following medications is commonly used to induce rapid sequence intubation?
Suxamethonium
ExplanationA neuromuscular blocking agent used for rapid and short duration paralysis.
#20
Which of the following is a complication associated with bag-mask ventilation?
Barotrauma
ExplanationDamage to the lungs caused by excessive pressure during bag-mask ventilation.
#21
What is the most appropriate initial intervention for a patient with suspected tension pneumothorax?
Needle decompression
ExplanationRelieving pressure in the chest cavity by inserting a needle into the pleural space.
#22
Which of the following is a potential complication of cricothyroidotomy?
Subcutaneous emphysema
ExplanationAir leaking into the tissues under the skin around the neck.
#23
Which of the following is a complication of prolonged bag-mask ventilation?
Hypercapnia
ExplanationBuildup of carbon dioxide in the bloodstream due to inadequate ventilation.
#24
Which of the following conditions is a relative contraindication for rapid sequence intubation?
Agitation
ExplanationPatient movement or agitation can complicate the intubation procedure.
#25
Which of the following medications is commonly used to treat bronchospasm in acute asthma exacerbation?
Ipratropium bromide
ExplanationA bronchodilator that helps relax the airway muscles and alleviate constriction.
