A patient with a tracheostomy tube is receiving positive-pressure ventilation through a volume ventilator. Over the past 5 min, 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?
a)Partial obstruction of the tracheostomy tube b)Complete obstruction of the tracheostomy tube c)Development of a left-sided pneumothorax d)Obstruction of the left bronchus by a mucus plug - ANSWER a)Partial obstruction of the tracheostomy tube
A patient with a tracheal airway exhibits severe respiratory distress. On quick examination, you notice the complete absence of breath sounds and no gas flowing through the airway. What is most likely the problem?
a)Partial tube obstruction b)Right-sided pneumothorax c)Complete tube obstruction d)Vocal cord paralysis - ANSWER c)Complete tube obstruction
After determining a patient has a complete obstruction of an oral endotracheal tube, your efforts to relieve the obstruction by moving the patient's head and neck and deflating the cuff both fail. What should be your next step?
a)Immediately extubate the patient. b)Try to pass a suction catheter. c)Call for an emergency tracheotomy.
d)Apply manual positive pressure. - ANSWER a)Immediately extubate the patient.
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?
a)Remove the tube and provide manual ventilation or oxygenation as necessary. b)Push the tube back into the trachea by moving the patient's neck up and down. c)Suction the oropharynx with a Yankauer (tonsillar) suction tip. d)Apply manual ventilation or oxygenation directly through the endotracheal tube. - ANSWER a)Remove the tube and provide manual ventilation or oxygenation as necessary.
What does a positive cuff leak test indicate?
a)The patient has significant upper airway edema. b)The patient's neuromuscular function is adequate to protect the lower airway. c)The patient is at minimal risk for upper airway obstruction. d)The patient's muscle strength will provide an effective cough. - ANSWER c)The patient is at minimal risk for upper airway obstruction.
Which of the following indicate that a patient being considered for extubation can provide adequate clearance of pulmonary secretions?
a)1 and 3 only
Although different techniques are used to actually remove the endotracheal tube during an extubation procedure, all aim to ensure which of the following?
a)Maximal adduction of the vocal cords b)Maximal abduction of the vocal cords c)Maintenance of the appropriate cuff pressure d)Elimination of the pharyngeal (gag) reflex - ANSWER b)Maximal abduction of the vocal cords
To minimize laryngeal swelling, a physician orders "continuous aerosol therapy" after the extubation of a patient. Which of the following specific approaches would you recommend?
a)Heated mist therapy through a jet nebulizer and aerosol mask b)Cool mist therapy through a jet nebulizer and aerosol mask c)Oxygen therapy through a "venti-mask" and bubble humidifier d)Racemic epinephrine or saline through a small jet nebulizer - ANSWER b)Cool mist therapy through a jet nebulizer and aerosol mask
You have been asked to monitor a patient who has just been extubated. Which of the following parameters would you monitor?
a)1, 2, and 3 only b)2 and 4 only
c)3 and 4 only d)2, 3, and 4 only - ANSWER a)1, 2, and 3 only
What is a rare but serious complication associated with endotracheal tube extubation?
a)Bradycardia b)Aspiration c)Infection d)Laryngospasm - ANSWER d)Laryngospasm
