Question: 1 / 400

A patient presents with dyspnea and diminished breath sounds along with a dull percussion note. What disease state is most likely affecting the patient?

Tension pneumothorax

Lung abscess

Atelectasis

Pleural effusion

The presentation of dyspnea, diminished breath sounds, and a dull percussion note strongly indicates the presence of pleural effusion. In this condition, excess fluid accumulates in the pleural space, which is the area between the lungs and the chest wall.

Diminished breath sounds occur because the fluid in the pleural space prevents effective transmission of sound from the lung tissue to the chest wall. Additionally, the dull percussion note results from the fluid's density, which contrasts with the normal resonance expected over healthy lung tissue; this dullness reflects the presence of fluid where air would normally be present.

Pleural effusion can cause significant respiratory distress due to the restricted expansion of the lungs and decreased lung volumes, leading to symptoms such as dyspnea. Collectively, these clinical markers lead to the conclusion that pleural effusion is the most likely disease state affecting the patient.
