RSP 331 Exam 1 2025

A patient referred for airflow limitations should withhold what medications?

An MD is describing PFT results as scooped out. What type of dz process does this describe?

A normal healthy adult can get what % of air out in the FEV6?

A patient had an MI 6 days ago. This would be a contraindication for spirometry

These 2 measurements are the most standardized indicators of obstruction.

A patient shows a mixed pattern on spirometry testing. what else should be ordered to evaluate for restriction?

A patient has stridor while playing basketball. What testing is indicated?

A patient has had trouble getting a VC 85-90% of highest with DLCO. They have done 5 tests. It is okay to do a 6th test.

This is an enhanced vital capacity, useful in identifying obstruction with the volume expired out in the 1st second

This testing is commonly ordered to identify restrictive lung disease.

This is the most commonly used diffusing capacity test.

A patient states the DLCO test was hard work and they need a break. How long do they have to wait to repeat it?

A patient with no lung hx has symptoms of dyspnea and a dry, persistent cough. What test would be indicated at this time

Patients should be asked to refrain from smoking for how long prior to PFT testing?

This lung volume method is preferred and is independent of gas distribution in the lungs.

this is the volume of gas remaining in the lungs at the end of a quiet breath.

What lung volume does pleth obtain and use to calcuate other volumes?

This manuever is the maximum volume of gas that can be expired when the patient exhales forcefully and rapidly

This ratio defines the fraction of TLC that cannot be exhaled as a percentage.

Interpretation of lung function should consider which key factors?

A patient is receiving bleomycin as part of cancer txt. what PFT test should be ordered?

A patient comes in for a PFT with a tie tightly around his neck. Why should he remove it?

This is the name of testing to assess airway response to a challenge, such as cold air or methacholine.

DLCO is often reduced in restrictive disorders such as pulmonary fibrosis.

What is a normal DLCO?

Diffusing capacity is measured by having a patient inhale a low concentration of what gas(es)?

A patient coughs within the first second of testing. You can still call the test acceptable.

Which of the following disorders could affect gas exchange?

You see that a patient is anemic when reviewing the chart. What precaution should you take with DLCO results?

The shape of the FVL is a "witches hat" with what dz pattern?

These results indicate hyperinflation and air-trapping

MRI can be used to calculate what lung volume?

These volumes and capacities are decreased in restrictive disease:

A patient is being assessed for emphysema and the MD wants to know the extent of hyperinflation. What should be ordered?

This test is required/recommended for diagnosis of obst. lung dz by GINA and GOLD organizations

This test simply measures the largest volume of air that can be moved in and out of the lungs.

A patient's FEV1/FVC ratio is lower than normal limits. This indicates what dz process?

A patient has a pre and post bronchodilator test. What % change in post FEV1 indicates positive response?
