Change to airway pressure release ventilation -CORRECT ANSWER >>-
A 60 kg (132 lb) patient is being mechanically ventilated with the following s
ettings: VC, A/C; VT 500 mL, respiratory rate 12/min, FIO2 1.0 and 10 cm H
2O PEEP. The patient's peak airway pressure is 60 cm H2O and his SpO2 i
s 85%. A current chest x-
ray shows diffuse bilateral infiltrates. Which of the following is the most appr
opriate action in order to reduce peak airway pressure?
2, 3 & 4 -CORRECT ANSWER >>-
While performing diagnostic chest percussion, the respiratory therapist n
otes decreased resonance to percussion. Which of the following are pote
ntial causes of this finding?.
1. pneumothorax
2. pleural effusion
3. pneumonia
4. atelectasis
Persistent bronchopleural fistula -CORRECT
ANSWER >>-A post- operative patient on volume-
,control ventilation has a chest tube in the left pleural space. While inspecti
ng the chest drainage system, the respiratory therapist notes
,bubbling in the water seal chamber during the inspiratory phase. The ther
apist should report this to the physician:
Increase the FiO2 -CORRECT ANSWER >>-A post-
operative patient is receiving mechanical ventilation in the ICU at the followi
ng settings: VC, A/C; VT550 mL, respiratory rate 14/min, FIO2 0.50 and 10
cm H2O PEEP. Bedside monitoring results demonstrate that the PvO2 is 33
mm Hg and the SpO2 is 90%. The patient is alert and oriented with stable v
ital signs. Which of the following should the respiratory therapist recommen
d?
1, 2 & 3 -CORRECT ANSWER >>-
After assisting with bronchoalveolar lavage and lung biopsy on a mechanica
lly ventilated patient, the respiratory therapist notes the activation of a high p
ressure alarm. Peak inspiratory pressure has increased from 32 cm H2O be
fore the procedure to 45 cm H2O after the procedure. Possible causes for th
e increased pressure include
1. bronchospasm
2. pneumothorax.
3. pulmonary hemorrhage.
, Endobronchial intubation -CORRECT ANSWER >>-Following blunt
chest trauma, a 35- year-
old male is orally intubated and continuous mechanical ventilation is initiat
ed. Physical assessment of the neck and chest reveal a midline trachea a
nd significant reduction in thoracic expansion of the left chest.
There are diminished breath sounds in the left lung compared to the right l
ung. These findings most likely indicate which of the following?
Tube is not of the appropriate size -CORRECT ANSWER >>-A 42 year-
old trauma patient in the ED has been intubated with a 6.5 mm oral endotra
cheal 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 indica
te that the:
Recalibrate the blood analyzer -CORRECT ANSWER >>-
A new blood gas analyzer is calibrated by the manufacturer at sea level. U
pon receiving the new analyzer at a higher altitude, a respiratory therapist
should:
Mean Airway Pressure -CORRECT ANSWER >>-
While receiving an FIO2 of 1.0 and a tidal volume of 400 mL during volume-
controlled ventilation, a 60-kg (132-
