PADI Divemaster Certification Practice Exam

What is the implication of a diver remaining on the surface after an emergency decompression failure?

1. The diver should start diving again in 15 minutes

2. The diver must be monitored for symptoms of decompression sickness

3. The diver can resume normal activities immediately

4. The diver should drink water to rehydrate

The correct answer is: The diver must be monitored for symptoms of decompression sickness

When a diver experiences an emergency decompression failure, remaining on the surface has significant implications for their safety. The correct response emphasizes the necessity of monitoring for symptoms of decompression sickness. Decompression sickness, often referred to as "the bends," can occur when a diver ascends too quickly or fails to decompress properly. After such an incident, even if the diver feels fine initially, latent symptoms may develop as nitrogen bubbles form in the bloodstream or tissues. Monitoring ensures that any symptoms, which may include joint pain, dizziness, shortness of breath, or neurological issues, are detected promptly. Early intervention can be crucial in preventing serious health consequences. The other potential responses don't adequately address the acute nature of decompression risks. For instance, resuming diving shortly after a decompression failure is unsafe, as it can exacerbate the risk. Immediate normal activities would not consider the physiological impact of potential bubbles in the body. While hydration is important for general dive health, it does not directly address the risks posed by decompression issues, making it an insufficient action following such an event.
