Men and women of the same age have differing lung volumes and airflow rates:

Best practice would be to interpret spirometric tests based on the LLN and Z-score rather than percentage of predicted?

For a Non-Caucasian subjects in Africa the following reference values should be selected:

The Forced Vital Capacity (FVC) is

Using this image of numerical results the FEV₁/FVC (actual) result you will use for interpretation of this result is:

The FEF25-75 is an indication of:

The recommended correct posture for testing is:

The best test is a new test created by the software taking the highest FVC and the
highest FEV₁ from all acceptable trials:

Eleven blows are considered a practical upper limit for most workers:

screening spirometry:

Which of the following descriptions is a test quality grade A

Which is the most correct statement. The best trail is:

The validity of data in spirometry is about:

The 3 key measurements used for interpretation are:

People with obstructive lung disease have:

People with restrictive lung disease:

These numerical Z-score results are indicative of what spirometry result:
FVC = -2.96 FEV₁ = -2.44 FEV₁/FVC = +1.86

These numerical Z-score results are indicative of what spirometry result:
FVC = +1.78 FEV1 = +1.68 FEV1/FVC = +2.00

These numerical Z-score results are indicative of what spirometry result:
FVC = -1.87 FEV1 = -2.04 FEV1/FVC = -1.96

The most common cause for restrictive impairments are which of the following:

An obstructive impairment is evident from which two of the following parameters?

A restrictive impairment is evident from which two of the following parameters?

A reduced FVC with a normal or elevated FEV1/FVC ratio is an indication of restriction:

Impaired lung functions are generally graded in Occupational Health to quantify respiratory impairment/ disability for medico-legal purposes, and to optimise and standardise treatment:

Are the following washout times of activities prior to testing true or false?
Activity: Smoking and/or vaping and/or water pipe use
Timeframe: 2 hours

Are the following washout times of activities prior to testing true or false?
Activity: Consuming intoxicants
Timeframe: 8 hours

Are the following washout times of activities prior to testing true or false?
Activity: Performing vigorous exercise
Timeframe: 15 minutes

Are the following washout times of activities prior to testing true or false?
Activity: Long acting bronchodilators
Timeframe: 6 hours

Are the following washout times of activities prior to testing true or false?
Activity: Short acting bronchodilators
Timeframe: 4 hours

Blowing induced bronchoconstriction in spirometry is:

Bronchodilator responsiveness testing is done to assess the relaxation of bronchial muscle to determine evidence of reversible airflow limitation:

A positive bronchodilator responsiveness test is a FEV1 or FVC change before and
after a bronchodilator test of >=12% and 200mls:

Spirometry equipment maintenance includes:

The subject must hold his/her breath for 30 seconds before exhaling when administering the medication via a spacer:

When giving the medication 4 puffs of 100ug is administered. The technician should
wait at least 10 seconds between the doses being administered:

After administering 400ug of bronchodilator medication, the technician should wait a minimum of 15 minutes for the medication to take effect before repeating the spirometry:

The following results indicate a positive bronchodilator responsiveness test:
Pre FEV1 1.26L, Post FEV1 1.41L / percentage change is 14%

The following results indicate a negative reversibility test:
Pre FEV1L 0.43, Post 0.49L / percentage change is 10%

Premature termination of a blow will lead to:

Glottic closure in spirometry is:

Height should be documented to within:

A valid test in spirometry consists of:

Test quality grade refers to:

In blowing induced bronchoconstriction there is:

If a worker displays blowing induced bronchodilation the technician should ask the worker to continue blowing until bronchodilation stabilises:

When grading the quality of the test session the pre and post bronchodilator test results are determined together
