A patient shows a right sided pleural effusion. Which of the
following should the respiratory therapist recommend?
A. sputum culture and gram stain
B. diagnostic bronchoscopy
C. pleurodesis
D. thoracentesis - ANSWER-D. Thoracentesis
Thoracentesis - a medical procedure that involves inserting a
needle or catheter into the chest wall to remove fluid or air from
the pleural space, the space between the lungs and chest wall.
A pt with exacerbation of COPD is receiving NPPV in spontaneous
mode with a nasal mask. The following data are available:
,FiO2 : 0.24 RR : 28/min IPAP : 12 cmH2O EPAP: 6 cmH2O
One hour later, the following data are available:
pH : 7.27 PaCO2 : 76 mmHg PaO2 : 62 mmHg HCO3- : 35 mEq/L
BE : +5 mEq/L SaO2(calc) : 90%
The inspiratory phase is prolonged and dyssynchrony is noted.
Which of the following should a RT do FIRST?
A. Increase the FiO2 to 0.28
B. Increase to EPAP 8 cmH2O
C. Change to a full-face mask
D. Change the ventilator circuit - ANSWER-C. Change to a full-
face mask
A pt who is 6'2" tall and weighs 98kg is receiving VC ventilation
with Vt 600mL. A RT observes the low exhaled volume and low
pressure alarms activating with each breath. The following data
are available: Vte: 340-390mL; ETT size: 8.5mm; ETT cuff pressure:
19cmH2O; ETT position: 18cm@incisor; HR 98; RR 32; SpO2 83%
Which of the following should the RT do?
A. advance the ETT @22cm
B. adjust the cuff pressure to 30cmH2O
C. increase the Vt to 700mL
,D. reintubate with a larger ETT - ANSWER-A. advance the ETT
@22cm
Advance ETT before adjusting cuff pressure
A RT is assisting a physician with insertion of a chest tube in a pt
with a pleural effusion. After the tube is place and the chest
drainage system is functioning properly, which of the following
should be observed in the water-seal chamber?
A. Continuous bubbling
B. Water level functioning with breathing
C. The water becoming cloudy
D. No visible liquid - ANSWER-B. Water level functioning with
breathing
A mini-bronchoalveolar lavage procedure is recommended for
diagnosis?
A. ventilator associated pneumonia
B. pleural effusion
C. pulmonary embolism
, D. idiopathic pulmonary fibrosis - ANSWER-A. ventilator
associated pneumonia (VAP)
A 44yo pt who underwent abdominal surgery is receiving
vibratory PEP therapy. After 24hr of q4h therapy, the patient can
ambulate independently while breathing air. A respiratory
therapist should recommend?
A. discontinuing therapy
B. obtaining an ABG analysis
C. performing a 6MWT
D. changing frequency of therapy to q8h - ANSWER-A.
discontinuing therapy
A RT is reviewing a chart of a 60yo male who is 5'10" tall, weighs
73kg and has moderate dyspnea. The CXR reports indicates the pt
has flattened diaphragm, severe hyperinflation, and small
cardiothoracic ratio. The PFT results are as follows: FVC 2.45L;
FEV1/FVC% 48%; FEF25-75% 1.25L/sec; FRC by Helium dilution:
3.75L; RV/TLC% 45%; DLCO 12mL/min/mmHg
Which of the following should the RT review to further evaluate
the extent of air trapping?
A. flow-volume loop
