,Immediately after extubation of a patient in the ICU, the respiratory therapist observes
increasing respiratory distress with intercostal retractions and marked stridor. The SpO2 on 40%
oxygen is noted to be 86%. Which of the following would be most appropriate at this time?

A patient is admitted to the ED following a motor vehicle accident. On physical exam, the
respiratory therapist discovers that breath sounds are absent in the left chest with a
hyperresonant percussion note. The trachea is shifted to the right. The patient's heart rate is
45/min, respiratory rate is 30/min, and blood pressure is 60/40 mm Hg. What action should the
therapist recommend first?
A. Call for a STAT chest x-ray.
B. Insert a chest tube into the left chest.
C. Needle aspirate the 2nd left intercostal space.
D. Activate the medical emergency team to intubate the patient. - VERRIFIED
ANSWERS✔◻✔◻--Needle aspirate the 2nd left intercostal space.

, All of the following strategies are likely to decrease the likelihood of damage to the tracheal
mucosa EXCEPT
A. maintaining cuff pressures between 20 and 25 mm Hg.
B. using the minimal leak technique for inflation.
C. using a low-residual-volume, low-compliance cuff.
D. monitoring intracuff pressures. - VERRIFIED ANSWERS✔◻✔◻--monitoring intracuff
pressures.
A 52 year-old post-operative cholecystectomy patient's breath sounds become more coarse upon
completion of postural drainage with percussion. The respiratory therapist should recommend
A. continuing the therapy until breath sounds improve.
B. administering dornase alpha.
C. administering albuterol therapy.
D. deep breathing and coughing to clear secretions. - VERRIFIED ANSWERS✔◻✔◻-- deep
breathing and coughing to clear secretions.
Which of the following patients would most likely benefit from pressure support ventilation?
A. An intubated patient with an absent respiratory drive.
B. A patient on SIMV with a set rate of 12/min and total rate of 24/min.
C. A patient with acute lung injury.
D. A patient who requires short-term post-operative ventilatory support. - VERRIFIED
ANSWERS✔◻✔◻--A patient on SIMV with a set rate of 12/min and total rate of 24/min.
A patient receiving mechanical ventilation has developed a temperature of 99.9° F with purulent
secretions over the last 12 hours. The respiratory therapist has also noted a steady increase in
