SDI Open Water Scuba Diver Practice Exam

What should you do if you accidentally exceed your dive computer's no-decompression limit?

1. Ignore it and continue diving

2. Make the decompression stop indicated by your dive computer

3. Surface immediately at full speed

4. Proceed back to shore without stopping

The correct answer is: Make the decompression stop indicated by your dive computer

If you accidentally exceed your dive computer's no-decompression limit, the appropriate action is to make the decompression stop indicated by your dive computer. Decompression limits are calculated based on various factors, including depth and time spent underwater, and exceeding these limits increases the risk of decompression sickness, also known as "the bends." By following the decompression stops as indicated by your dive computer, you allow your body to safely eliminate excess nitrogen accumulated in your tissues during the dive. This process is essential for preventing bubbles from forming in your bloodstream and tissues, which can result in serious health consequences. Remaining aware of your dive computer's guidance not only enhances your safety but also reinforces good diving practices. Other actions, such as ignoring the issue or surfacing immediately, directly compromise diver safety and can lead to life-threatening conditions. Thus, adhering to the dive computer's stops is crucial for responsible diving.
