CRE Patient Assessment & Diagnosis 2

Question 1

A patient with COPD presents with accessory muscle use, pursed-lip breathing, and a barrel chest. Which physical finding is most consistent with hyperinflation?

Accepted Answer

Decreased diaphragmatic excursion

Answer

Hyperinflation flattens the diaphragm, reducing its excursion and limiting effective breathing mechanics.

Question 2

Which spirometry pattern is characterized by a reduced FVC, reduced FEV1, and a normal or elevated FEV1/FVC ratio?

Accepted Answer

Restrictive pattern

Answer

A restrictive pattern shows proportionally reduced FVC and FEV1 with a preserved or elevated FEV1/FVC ratio.

Question 3

A respiratory educator is reviewing a patient's ABG: pH 7.30, PaCO2 55 mmHg, HCO3 27 mEq/L. What is the primary disorder?

Accepted Answer

Respiratory acidosis with partial compensation

Answer

Elevated PaCO2 with low pH indicates respiratory acidosis; the elevated HCO3 shows renal compensation has begun.

Question 4

When performing a 6-minute walk test (6MWT) on a COPD patient, which finding most indicates a need to stop the test immediately?

Accepted Answer

SpO2 drops below 80%

Answer

An SpO2 below 80% is a critical stopping criterion for the 6MWT due to severe hypoxemia risk.

Question 5

Which auscultation finding is most commonly associated with pulmonary fibrosis?

Accepted Answer

Fine, late-inspiratory crackles (Velcro crackles)

Answer

Pulmonary fibrosis produces fine, late-inspiratory crackles often described as Velcro-like due to fibrotic tissue opening during inspiration.
