patient being mechanically ventilated requires endotracheal suctioning. The patient is on high
levels of PEEP therapy and has periods of hypotension. The respiratory therapist
hyperoxygenates the patient before beginning the procedure. As the therapist disconnects the
patient from the ventilator circuit, the following pattern is seen on the ECG monitor:
Which of the following could be the cause of this patient's ECG pattern?
A. loss of PEEP
B. inadequate hyperoxygenation time

requested that the right lung be ventilated at a pressure 10 cmH2O lower than the left lung. The
respiratory therapist should recommend providing this type of ventilation via a:
A. Transtracheal catheter device
B. Double-lumen endobronchial tube
C. Cricothyroidotomy
D. 14 gauge endotracheal catheter - ANS *B. Double-lumen endobronchial tube*
A patient has been intubated in order to receive volume control ventilation. To inflate the
endotracheal tube cuff, the respiratory therapist should add air to the cuff
A. until no leak is heard during inspiration.
B. and then remove it until a slight leak is heard at peak inspiration.
C. to establish a pressure of 20 mmHg.
D. to establish a pressure of 40 cmH20. - ANS *C. to establish a pressure of 20 mmHg*
