RT 250 PFT Unit Exam UPDATED ACTUAL QUESTIONS AND CORRECT
ANSWERS
You are assigned to perform a nitrogen washout FRC c
maneuver on a patient. You should start the test after the
patient:
a. takes a deep breath
b. inhales normally
c. exhales normally
d. exhales forcefully
Which of the following equations is NOT correct? a
a. ERV + VT + FRC = TLC
b. IRV + Vt + ERV + RV = TLC
c. IC + FRC = TLC
d. VC + RV = TL
Which of the following is NOT a lung capacity? d
a. FRC
b. TLC
c. FVC
d. IRV
If TLC = 5.8 L, VT= 0.6 L, and IRV= 1.2 L, then FRC equals: c. (VT+IRV-TLC)
a. 6.4 L
b. 3.6L
c. 4.0L
d. 5.0L
, Don't know the answer? (NOT C) a
With a restrictive disorder all of the followings can
decrease, EXCEPT:
a. FeV1% (FEV1/FVC)
b. TLC
c. FVC
d. FEV1
The volume that can be inhaled above a resting tidal c
volume?
a. ERV
b. VC
c. IRV
d. RV
Which of the following patient is NOT a good candidate b
for PFT?
a. screening for presence of pulmonary obstructive
disease
b. post abdominal operation assessment
c. determining lungs diffusion capacity
d. determining the effectiveness of pulmonary
rehabilitation
All of the following techniques can be used to measure b
RV with the exception of:?
a. Helium dilution
b. Flow-volume loops
c. Body plethysmography
d. Nitrogen washout
A COPD patient has reduced FVC and FEV1 compared to b
his predicted values. His FEV1% ( FEV1/FVC) is also
reduced. In order to further evaluate this patient for the
presence of a restrictive disorder in addition to
obstructive, you should also consider examining:
a. FEF 200-1200
b. TLC, and FRC
c. airway resistance
d. Peak expiratory flow
