1- When evaluating the area superior to a confirmed hydro-point in a patient with hydropneumothorax, which M-mode finding would corroborate the diagnosis of pneumothorax?
1. Seashore Sign
2. Stratosphere Sign
3. Plankton Sign
4. Lung Pulse
2- In a patient with pyopneumothorax, TUS reveals rapidly rising, intensely hyperechoic speckles within the pleural fluid, synchronous with respiration. What is the underlying material causing this 'Microbubbles Sign'?
1- Aggregated pus cells
2- Entrained air bubbles
3- Fibrin strands
4- Proteinaceous debris
3- How is the typical movement pattern of the Plankton Sign distinguished from that of the Microbubbles Sign on dynamic sonographic assessment?
1- It is characterized by a uniform, shimmering field that does not stream.
2- It shows rapid, streaming movement rising directly toward the hydro-point.
3- Its movement is completely static and fixed within the effusion.
4- It demonstrates a slower, swirling or whirling motion driven by passive impulses.
