Which of the following is a classic sign of pulmonary oedema?AWheezingBCracklesCReduced breath soundsDNormal lung sounds

Break Down the Problem

1. Identify classic signs of pulmonary edema.
2. Evaluate each option based on its relation to pulmonary edema.

Relevant Concepts

Pulmonary edema is a condition characterized by excess fluid in the lungs, which often leads to specific respiratory signs upon clinical examination. Commonly assessed lung sounds include wheezing, crackles, reduced breath sounds, and normal lung sounds.

Analysis and Detail

1. Wheezing usually indicates bronchospasm or constriction of the airways; it's not typically a classic sign of pulmonary edema.
2. Crackles (or rales) are often heard in patients with pulmonary edema due to fluid in the alveoli. They signify the presence of abnormal lung fluid.
3. Reduced breath sounds might be observed but not as a classic sign; it can point toward various lung pathologies.
4. Normal lung sounds would indicate a healthy respiratory system, thus not associated with pulmonary edema.

Verify and Summarize

The presence of crackles is closely linked to pulmonary edema, making it a classic sign. Therefore, after assessing each option, the choice that aligns with typical findings in pulmonary edema is crackles.

Final Answer

B. Crackles
