*A. The F02 of the gas delivered to the bag.* - Answers When using a flow-inflating resuscitation
bag during manual ventilation of a neonate, the FO2 received by the neonate is determined by
A. the FO2 of the gas delivered to the bag.
B. the size of the oxygen reservoir.
C. the oxygen flow rate.
D. how much the bag is compressed.
*A. loss of PEEP* - Answers 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
C. vagus nerve stimulation
D. normal response to suctioning
*B. Double-lumen endobronchial tube* - Answers A patient is diagnosed with a necrotizing
pulmonary fistula in the right lung. The physician has 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
*C. to establish a pressure of 20 mmHg* - Answers 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.
*B. fenestrated tracheostomy tube* - Answers A 16-year-old male patient involved in a
motorcycle accident presents to the ER with massive maxillary and nasal trauma. Which of the
