How much do you know about airway management? We have this "Airway management MCQs quiz" to test your knowledge. Anesthetists need to ensure your breathing is adequate and safe once you are asleep. Oxygen needs to be provided and other gases eliminated from your lungs. Your breathing passages need to be protected from soiling from stomach contents during an anesthetic. Take up the quiz and test your knowledge of airway management.
ABG
Clinical assessment
Lung auscultation
Pulse oximetry alone
Testing the gag reflex
Failure to maintain or protect the airway.
Failure of ventilation or oxygenation.
Patient’s anticipated clinical course and likelihood of deterioration.
All of the above.
Aspiration technique
Chest and gastric auscultation
Chest x-ray
Fiberoptic scope can be passed through the endotracheal tube to identify tracheal rings
End-tidal carbon dioxide (CO2) color change
Has a receding mandible
Has a short neck
Has no teeth
Has prominent upper incisors
Is immobilized due to potential neck trauma
Chin lift
Direct tongue depression
Head tilt
Jaw thrust
None of the above
Prior neck surgery
Hematoma, tumor, or abscess on the neck
Scarring from radiation on the neck
Obesity
Class III or Class IV Mallampati
Suspected cervical spine injury
Restricted mouth opening
Stiffness (resistance to ventilation)
Obstruction or obesity
Distorted anatomy

Phencyclidine derivative
Increases intracranial pressure
Causes hypotension
Never causes myoclonus
Induction dose is 0.3mg/kg IV.
Can increase intracranial pressure
Bronchoconstrictor
Can increase blood pressure
Can cause an emergence phenomenon (frightening dreams)
1-2mg/kg produces loss of awareness within 30 seconds, peaks in 1 minute, and lasts 10-15 minutes.
Thiopental
Ketamine
Midazolam
Etomidate
MOANS = mnemonic for difficult extra-glottic device placement
RODS = mnemonic for difficult cricothyrotomy
LEMON = mnemonic for evaluation of difficult direct laryngoscopy
SHORT = mnemonic for difficult extra-glottic device placement
HELP = mnemonic for difficult cricothyrotomy
Succinylcholine is rapidly acting and can produce intubation conditions within 10 seconds of administration by rapid IV bolus.
The clinical duration of action of succinylcholine before spontaneous respirations occurs is 20 minutes.
Use of 0.5 mg/kg of succinylcholine results in both less fasiculations and less myalgias than occur with 1mg/kg.
Succinylcholine has been associated with masseter spasm and malignant hyperthermia.
Succinylcholine is contraindicated in renal failure, acute burns, strokes and spinal cord injuries because of its propensity to cause hyperkalemia.
Cervical spine fracture
Apnea
Depressed mental status
Hypotension
Pneumothorax
Airways such as the laryngeal mask airway and esophageal obturator airway are available in the event of a failed airway.
Awake intubation may be done by the nasotracheal route.
Care should be taken before intubation to assess the airway for ease of ventilation as well as intubation.
Cricothyrotomy is the crucial rescue procedure when intubation and ventilation fail.
All of the above are true.
Bleeding in the airway
Cervical spine injury
Epiglottitis
Limited mouth opening
Protuberant teeth
Acute airway obstruction
Age younger than 10 years
Apnea
Inability to orotracheally or digitally intubate
Severe facial trauma
Etomidate
Ketamine
Propofol
Rocuronium
Thiopental
Inspiratory to expiratory ration should be kept at 1:2, and 14 breaths/minute
Ketamine is the preferred paralytic agent
Nasotracheal intubation is preferred over orotracheal
Propofol can be used as a sedating agent
Tidal volume should be kept at 10mL/kg ideal body weight.
Preservation of speech, swallowing, and physiologic airway defense mechanisms
Reduced risk of airway injury
Reduced risk of nosocomial infection
Decreased length of stay in, and reduced need for ICU admission.
All of the above
Severely impaired level of consciousness
Uncontrolled vomiting
Acute MI
Copious secretions
Pneumonia
Tachycardia and hypertension can indicate ventilatory intolerance and a need for increased sedation or adjustment of ventilatory settings.
Recommended initial settings for BiPAP ventilators are IPAP 100 % and EPAP of 50%.
Reasonable initial ventilatory settings are a TV of 12ml/kg body mass and a rate of 16 breaths/minute.
PEEP should be initiated at 15cm H2O
Bradycardia and ventricular irritability represents oxygen toxicity.
Patients requiring continuous BP monitoring (sodium nitroprusside)
Patients with impending shock states
Patients with anatomic abnormalities
Normotensive patients
Patients who require frequent arterial samplings
A purple color is associated with CO2 less than 4mm Hg.
A yellow color is associated with CO2 greater than 20mm Hg.
Purple color generally indicates esophageal intubation.
Ambient CO2 levels in the esophagus are less than 4mm Hg
All of the above are true.
