What action should you take immediately when a diver shows signs of distress?

When a diver shows signs of distress, the immediate action to take is to begin rescue procedures. This response is crucial because a distressed diver can quickly worsen the situation if not addressed promptly. Immediate action ensures that you provide the necessary assistance quickly, thereby potentially preventing further complications, such as panic, inhalation of water, or drowning.

Starting rescue procedures can involve several steps, such as assessing the situation, signaling for assistance if needed, and preparing to provide aid. It's essential to prioritize the safety of both the distressed diver and yourself, maintaining a calm and composed demeanor throughout the process to effectively manage the situation.

Other options, such as waiting for a few minutes, calling for help, or confirming buoyancy status, can lead to delays that may exacerbate the diver’s condition. Immediate intervention is key to ensuring the safety and well-being of the individual in distress.
