Total questions: 10
Worksheet time: 20mins
2. The Mallampati classification focuses on the visibility of oropharyngeal structures when the patient is examined in which of the following positions?
Supine, mouth fully open, tongue protruded, with phonation
Semirecumbent, mouth fully open, tongue protruded, without phonation
Sitting, mouth opened, tongue in neutral position, without phonation
Sitting, mouth fully opened, tongue protruded, without phonation
Sitting, mouth fully opened, tongue protruded, with phonation
3. Risk factors for aspiration of gastric contents at the time of airway management include all of the following EXCEPT:
Emergency surgery
Higher ASA classification
Small bowel obstruction
Obesity
Inexperienced anesthetist encountering airway problems
4. Cricoid pressure (Sellick’s maneuver) can be used in an attempt to
Reduce gastric distention during bag-mask ventilation
Reduce passive regurgitation of gastric contents
Improve laryngoscopic view by applying backward, upward, and rightward pressure
Occlude the esophagus against the C6 vertebra
All of the above
5. Which of the following choices of endotracheal tube (ETT) size and position is most appropriate?
12-month-old—3.0 ETT taped at 7 cm at the mouth
2-year-old—4.5 ETT taped at 8 cm at the mouth
3-year-old—4.5 ETT taped at 13 cm at the mouth
6-year-old—6.5 ETT taped at 12 cm at the mouth
10-year-old—7.0 ETT taped at 15 cm at the mouth
6. Which of the following is NOT a suggested use for the laryngeal mask airway?
Emergency ventilation when tracheal intubation has failed
Assisting a tracheal intubation
To protect against aspiration
Providing an airway with minimal changes in blood pressure and heart rate
To assist in fiberoptic bronchoscopy
7. The process of preoxygenation/denitrogenation greatly increases the time to desaturation during intubation. The reasons for failure to achieve an FiO 2 close to 100% include leak, rebreathing of gases, and using systems incapable of delivering highly enriched oxygen. The main causes of circuit leak include all of the following EXCEPT:
Beards
Edentulous patients
Nasogastric tubes
Incorrect facemask size
None of the above
8. Shortly aft er the induction of general anesthesia and during mask ventilation, bile-stained fluid filling the facemask is observed. Your next course of action should be all of the following EXCEPT:
Turn the patient’s head to the side.
Call for help.
Attempt to clear the pharynx of gastric fluid with a Yankauer suction.
Check the patient’s vital signs.
Place the patient into the reverse Trendelenburg position.
9. You are called to evaluate a patient in the medical intensive care unit with an ETT cuff leak. Your first course of action should be which of the following?
Review the most recent x-ray and order another.
Check the patient’s vital signs and evaluate for immediate reintubation.
Suction the posterior oropharynx.
Deflate the pilot balloon.
Add additional air to the cuff .
10. Hypoxemia is defi ned as a partial pressure of oxygen in arterial blood (Pa o2 ) less than _______ mm Hg while breathing room air.
