Pulmonary Function Tests (PFT) Exam
The pulmonary diffusion capacity of carbon monoxide test is used to -
✔ ✔ assess the alveolar-capillary membrane
Which answer BEST describes what the FeV1/FVC will be for a patient
with emphysema - ✔ ✔ <70%
A minimum increase of ____% and ____ml in the FEV1 post
bronchodilator study is considered significant change with
bronchodilator therapy. - ✔ ✔ 12, 200
The normal FeV1 for a normal healthy adult is approximately - ✔ ✔
80%
A respiratory therapist is repeating pulmonary function testing on a
patient who had initial pulmonary function testing 6 months ago. With
the first FVC attempt, the therapist notices the patient was only able to
accomplish an FEV1.0 sec of 50% of predicted. Six months prior, the
patient was able to reliably accomplish 85% of predicted. The therapist
should - ✔ ✔ repeat the effort, encourage the patient to increase
effort
How do you determine the best trial for a patient doing a flow volume
loop manuever? - ✔ ✔ Whichever trial has the highest value when
adding together the Fev1 and FVC results
A patient has an actual SVC of 3.55 her predicted SVC was 3.75. This
indicates that she obtained 94% of her predicted value. This indicates
that she is restrictive. - ✔ ✔ False
, What volumes can be added together to equal the TLC? - ✔ ✔
VC+RV
The best test is the trial that results from the largest sum of FeV1+ FVC -
✔ ✔ true
Select all that are indicative of restrictive disorders - ✔ ✔
pulmonary edema
pleural disease
thoracic deformities
post thoracic surgery patients
A 58 year old woman has a predicted FVC of 5.0 Liters and a predicted
FeV1 of 3.83. Her actual observed FVC is 3.0 and her actual observed
FeV1 is 2.50 - ✔ ✔ she has decreased compliance
she is not obstructive
she is restrictive
Residual Volume - ✔ ✔ 1200
Inspiratory Capacity - ✔ ✔ 3600
FRC - ✔ ✔ 2400
VC - ✔ ✔ 4800
What is the primary function of the lungs? - ✔ ✔ 1. Oxygenation of
mixed venous blood.
2. Removal of carbon dioxide from mixed venous blood.
