The basic technique that divers should execute if they ascend too quickly is to conduct a safety stop at 15 feet for 3 minutes. This practice is crucial because ascending too quickly can lead to decompression sickness due to the nitrogen that has been absorbed by the body at greater depths. A safety stop allows divers to off-gas nitrogen gradually, significantly reducing the risk of developing DCS.

During the safety stop, the diver should pause at around 15 feet, which is a common depth for stopping to allow the body time to eliminate the excess nitrogen safely. This procedure is important for divers to be aware of, as it promotes safer diving practices and enhances the overall safety of diving activities.

The other choices do not provide appropriate responses to a rapid ascent. Continuing to swim to the surface or waiting for help does not address the potential physiological dangers that can arise from a quick ascent, and diving back down to regain depth can actually worsen any potential injuries caused by the abrupt change in pressure. While these options may seem pragmatic under stress, they lack the preventative measures necessary to safeguard the diver’s health.
