Which risk is NOT associated with exceeding no-decompression limits?

Exceeding no-decompression limits primarily leads to risks associated with the formation of nitrogen bubbles in the body, which can result in conditions such as Decompression Sickness (DCS) and Air Embolism. DCS occurs when a diver ascends too quickly after being saturated with nitrogen at depth, causing bubbles to form as the pressure decreases. Air Embolism can happen if a diver holds their breath and ascends, causing air trapped in the lungs to expand and potentially rupture blood vessels.

The bends, another term for DCS, specifically refer to the painful symptoms caused by these gas bubbles affecting joints and tissues.

In contrast, exhaustion from prolonged diving is not directly linked to the act of exceeding no-decompression limits. While prolonged diving can indeed lead to exhaustion due to extended physical exertion and potential fatigue, this is not a specific risk of exceeding no-decompression limits but rather a general concern with any deep and lengthy dives. Therefore, this option appropriately identifies a risk that is not directly tied to the consequences of exceeding these limits.
