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. Answer:
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.. Answer: 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.. Answer: deep
breathing and coughing to clear secretions.

graphics. Which of the following controls, when adjusted independently,
would increase expiratory time?

static lung compliance
A. 25 mL/cm H2O

C. 45 mL/cm H2O
D. 50 mL/cm H2O. Answer: 50 mL/cm H2O
⩥ 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?
