Question 2

  1. Manual chest compression and TT suctioning
  2. Autogenic drainage and postural drainage
  3. Positive expiratory pressure
  4. Mechanical insufflation-exsufflation (MI-E)
 
  a. 1 and 4 only
  b. 1, 2, and 3 only
  c. 2 and 3 only
  d. 1, 2, and 4 only

Answer to Question 1

ANS: B
For speech to occur, tracheal pressures of approximately 2 cm H2O are required to vibrate the vocal cords and produce a quality voice.

Answer to Question 2

ANS: A
Because this patient has ALS and is ventilator dependent, removing the patient will not enable the RT to perform PEP therapy or autogenic drainage. Assisted coughing with manual chest compression helps to mobilize secretions into an area in the larger airways that can be suctioned. MI-E also is appropriate for a patient, such as this one, who is unable to generate enough expira-tory flow for a cough.
