Exam 33: Airway Management

Which of the following methods can help to reduce the likelihood of atelectasis due to tracheal suctioning? I. Limit the amount of negative pressure used. II. Hyperinflate the patient before and after the procedure. III. Suction for as short a period of time as possible.

In which of the following conditions should fiberoptic bronchoscopy NOT be performed if the risks outweigh the potential benefits? I.uncorrected bleeding disorders II.presence of lung abscess III.refractory hypoxemia IV.unstable hemodynamic status

What is the average depth of proper nasal endotracheal tube insertion in adult men?

Although different techniques are used to actually remove the endotracheal tube during an extubation procedure, all aim to ensure which of the following?

A patient with a tracheal airway exhibits signs of tube obstruction. Which of the following are possible causes of this obstruction? I. The tube cuff has herniated over the tip of the tube. II. The tube is obstructed by a mucus plug or secretions. III. The tube is kinked, or the patient is biting the tube. IV. The tube orifice is impinging on the tracheal wall.

What is a rare but serious complication associated with endotracheal tube extubation?

Which of the following is false about cuff inflation techniques (MOV = minimal occluding volume; MLT = minimal leak technique)?

Compared with traditional surgical tracheostomy, all of the following are TRUE about percutaneous dilatational tracheostomy except:

Which of the following factors should be considered when deciding to change from an endotracheal tube to a tracheostomy tube? I.patient's tolerance of the endotracheal tube II.relative risks of continued intubation versus tracheostomy III.patient's severity of illness and overall condition IV.length of time that the patient will need an artificial airway V.patient's ability to tolerate a surgical procedure

What is the purpose of an endotracheal tube stylet?

When using capnometry or colorimetry to differentiate esophageal from tracheal placement of an endotracheal tube, which of the following conditions can result in a false-negative finding (i.e., no CO₂ present even when the tube is in the trachea)?

Which of the following conditions require emergency tracheal intubation? I.upper airway or laryngeal edema II.loss of protective reflexes III.cardiopulmonary arrest IV.traumatic upper airway obstruction

Compared with translaryngeal intubation, the advantages of tracheostomy include all of the following except:

A patient with a tracheostomy tube is receiving positive-pressure ventilation through a volume ventilator. Over the past 5 minutes, the peak inspiratory pressure has risen, and the pressure limit alarm is now sounding. On quick examination, you notice a generalized decreased in breath sounds. Which of the following problems is most likely?

Ideally, the distal tip of a properly positioned endotracheal tube (in an adult man) should be positioned about how far above the carina?

Which of the following injuries are NOT seen with tracheostomy tubes? I.tracheomalacia II.tracheal stenosis III.glottic edema IV.vocal cord granulomas

A patient receiving mechanical ventilatory support accidentally displaces the endotracheal tube out of the trachea. What would be the most appropriate action at this time?

To ensure adequate humidification for a patient with an artificial airway, inspired gas at the proximal airway should be 100% saturated with water vapor and at which of the following temperatures?

To maintain positive end-expiratory pressure (PEEP) and high FIO₂ when suctioning a mechanically ventilated patient, what would you recommend?

Which of the following features incorporated into most modern endotracheal tubes assist in verifying proper tube placement? I.length markings on the curved body of the tube II.imbedded radiopaque indicator near the tube tip III.additional side port (Murphy eye) near the tube tip
