After a patient undergoes a thoracentesis, the respiratory therapist notes that the
obtained pleural fluid is clear with a slight straw color. This fluid is most likely the
result of
A. empyema.
B. congestive heart failure.
C. lung carcinoma.
D. hemothorax. - SOLUTION-Congestive Heart Failure
The respiratory therapist is calibrating a spirometer and checking the volume with
a 3.0 liter super syringe. the volumes recorded are 2.85L, 2.8L and 2.8L. Based
upon the information obtained, which of the following is a correct statement?
A. Another syringe needs to be used
B. Spirometer is accurate
C. The plunger was advanced too slowly
D. Spirometer may have a leak - SOLUTION-D. Spirometer may have a leak
Which of the following is an indication for high frequency jet ventilation?
A. Bronchopleural fistula
,B. Wilson Mikity syndrome
C Necrotizing lesion of right lung
D. Centrilobular emphysema - SOLUTION-Bronchopleural Fistula
**(because it uses mean airway pressures & low tidal volumes to improve
oxygenation and we do not want to worsen bp fistula)
A patient with chronic hypercapnia is brought into the ED. the history of the
present illness revealed that the patient passed out at home. A pulmonary artery
catheter has been placed with the following measurements obtained:
PAP 25/10 mmHg
BP 76/50 mmHg
PCWP 4 mmHg
SVR 1360 dynes
CVP 0 mmHg
CI 1.8L/min/m2
Which of the following is the most likely cause for his condition?
A. Hypovolemia
B. Drug OD
C. Cor pulmonale
D. High FiO2 vasodilation - SOLUTION-A. Hypovolemia
Which of the following will give the most accurate measurement of volume and
flow for spirometry?
, A. Collins water-sealed spirometry
B. Vortex-shedding pneumotachometer
C. Wright respirometer
D. Dry-rolling spirometer - SOLUTION-Collins water-sealed spirometry
All of the flowing are TRUE statements about spacers and holding chambers
EXCEPT:
A. Do not require patient cooperation with their breathing pattern
B. Improve the efficiency of an MDI
C. Can be used for drug delivery by MDI to intubated and mechanically ventilated
patients
D. If a patient exhales immediately following activation of the inhaler, they will
clear the medication from the device and waste the dose - SOLUTION-A. Do not
require patient cooperation with their breathing pattern
A 19 y/o patient has a size 7 mm ID nasotracheal tube placed through the right
nare. While attempting to suction the patient with a size 12 Fr catheter, resistance
is met as the catheter is introduced into the ETT.
The RT should:
A. Lubricate the catheter with petroleum jelly prior to suctioning
B. Instill acetylcysteine into the ETT
C. Switch to a 10 Fr suction catheter
D. Extubate the patient and reintubate with a size 9 mm ID ETT -
SOLUTION-C. Switch to a 10 Fr suction catheter
