A 30 year old male with bronchitis has coarse bilateral rales with a SpO2 of 90%.Despite a good cough effort, he has great difficulty in removing his thick secretions. The respiratory therapist should initiate

• aerosol treatments with 3 cc normal saline every 4 hours.
• sputum induction for gram stain.
• a heated humidifier and oxygen therapy.
• continuous ultrasonic via aerosol mask. - CORRECT ANSWER: a heated humidifier

and oxygen therapy.

A 42 year-old trauma patient in the ED has been intubated with a 6.5 mm oral endotracheal tube equipped with a high-residual-volume, low-pressure cuff. The respiratory therapist notes that a cuff pressure of 42 cm H2O is necessary to achieve a minimal occluding volume. This would indicate that the

• tube is not of the appropriate size.
• pilot balloon and line are obstructed.
• pressure manometer is defective.
• cuff has herniated over the tip of the tube. - CORRECT ANSWER: tube is not of the

appropriate size.

A 44 year-old patient who suffered a cerebral vascular accident has been moved from Neuro-ICU to the step-down unit. He becomes diaphoretic and his SpO2 suddenly drops from 95% to 88% on a 32% tracheostomy collar. His heart rate is 115/min, respiratory rate is 42/min and his breath sounds are very diminished. The respiratory 2 / 4

therapist is unsuccessful in attempting to pass a 12 Fr suction catheter. The therapist should

• increase the suction pressure to 120 mm Hg.
• change to a 10 Fr suction catheter.
• replace the tracheostomy tube.
• orally intubate the patient. - CORRECT ANSWER: Replace the tracheostomy tube.

The chest radiograph demonstrates diffuse bilateral radiopacity. ABG results are: pH 7.36, PaCO2 47 torr, PaO2 50 torr, and HCO3- 28 mEq/L. The respiratory therapist should increase the

A. PEEP.

B. FIO2.

• expiratory time.

D. respiratory rate. - CORRECT ANSWER: PEEP

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

• continuing the therapy until breath sounds improve.
• administering dornase alpha.
• administering albuterol therapy.

D. deep breathing and coughing to clear secretions. - CORRECT ANSWER: deep

breathing and coughing to clear secretions.

A 52 year-old post-operative patient's chest radiograph demonstrates infiltrates in the posterior basal segments of the lower lobes. Which of the following is the appropriate postural drainage position?
