Egans-PFT Chapter 20 Exam with
complete solutions latest version
What are the three categories of PFTS? - CORRECT ANSWER-1. dynamic flow
rates of gases through airways 2. lung volumes and capacities 3. the ability of
lungs to diffuse gases
Generally what are the primary purposes of PFT? - CORRECT ANSWER-to
identify pulmonary impairment and quantify the severity of pulmonary impairment
What are the indications for PFT? - CORRECT ANSWER-to identify and quantify
changes; need and therapeutic effectiveness; epidemiologic surveillance; assess
postoperative risks; determine disabililty
What are the contraindications for PFT? - CORRECT ANSWER-acute unstable
cardiopulmonary problems (hemoptysis, pneumothorax, MI, pulmonary
embolism) ;acute chest or abdominal pain; nauseated or recently vomited
patients; dementia patients
When should PFT be delayed? - CORRECT ANSWER-patients who have had
recent cataract removal surgery, due to changes in ocular pressure
When may the validity of measuring the FVC be hindered? - CORRECT ANSWER-
acutely ill patients; those that recently smoked a cigarette
What are the two major categories for pulmonary disease? - CORRECT ANSWER-
obstructive pulmonary disease; restrictive pulmonary disease
What is the primary problem in obstructive pulmonary disease? - CORRECT
ANSWER-increased airway resistance
What is the primary problem in restrictive pulmonary disease? - CORRECT
ANSWER-reduced lung compliance, thoracic compliance, or both
What are the characteristics of obstructive disease? - CORRECT ANSWER-affects
airways; on expiration; increased airway resistance; useful to measure flow rates
, www.stuvia.com/doc
What are the characteristics of restrictive disease? - CORRECT ANSWER-affects
lung parenchyma, thoracic pump; on inspiration; decreased lung or thoracic
compliance; useful to measure volumes or capacities
What is reduced lung compliance a result of? - CORRECT ANSWER-alveolar
inflammation (pneumonia); swelling (pulmonary edema); or scarring (pulmonary
fibrosis)
What is reduced thoracic compliance a result of? - CORRECT ANSWER-thoracic
wall abnormalities (kyphoscoliosis) ; or exogenous pressure exerted on the
thoracic cavity (ascites, pregnancy).
What can identify the destruction of alveolar tissue or the loss of functioning
alveolar surface? - CORRECT ANSWER-Measuring the DLCO (diffusing capacity
of the lung for carbon monoxide)
For each measurement of pulmonary function, there is a ________value and
________ and _________ limit of normal (ULN and LLN) - CORRECT ANSWER-
predicted; upper; lower
A healthy individual would fall between what 2 values? - CORRECT ANSWER-the
(LLN) lower limit and the (ULN) upper limit
Patients with oral__________ or active____________infections pose the greatest
potential hazard - CORRECT ANSWER-lesions; respiratory
Who is at the greatest risk during PFT? - CORRECT ANSWER-patients with
compromised immune systems
What are the two general types of measuring instruments? - CORRECT ANSWER-
ones that measure gas volume; and ones that measure gas flow
What do both types of measuring instruments measure simultaneously? -
CORRECT ANSWER-time
What is a device that measures volume usually referred to as? - CORRECT
ANSWER-spirometer
The magnitude of the expansion is the _____________measured - CORRECT
ANSWER-volume
The speed of expansion represents the __________rate - CORRECT ANSWER-
flow
What is a device that measures flow usually referred to as? - CORRECT
ANSWER-pneumotachometer
For tests of pulmonary function, what general principles should be considered? -
CORRECT ANSWER-test sensitivity and specificity; validity; reliability
