Which pair correctly states normal bladder wall thickness for empty and distended states?

Which pair correctly states normal bladder wall thickness for empty and distended states?

• A. 5 / 3
• B. 3 / 5
• C. 4 / 2
• D. 6 / 4

Answer: (A)

Bladder wall thickness changes with how full the bladder is. When the bladder is empty, the walls are more contracted and folded, making the measured wall thicker. As it fills and stretches, the wall becomes thinner. In adults, a typical normal empty-wall thickness is about 5 millimeters, and a distended bladder is about 3 millimeters thick. So the pair listing 5 mm for empty and 3 mm for distended matches this pattern. The other options would imply the wall thickens with distension or show values outside the normal range, which doesn’t fit how the bladder responds to filling.
