PADI Divemaster Certification Practice Exam

Using the eRDPML, multilevel dive limits must be determined for what purpose?

1. To establish the number of dives possible in a day

2. To identify the equipment needed for specific depths

3. To manage pressure groups and adjust limits for each level of dive

4. To create a dive log for future reference

The correct answer is: To manage pressure groups and adjust limits for each level of dive

Multilevel dive limits are primarily determined to manage pressure groups and adjust limits for each level of dive. This is crucial because when divers engage in multilevel dives, they will be ascending and descending through different depths during the dive. As a result, the diver’s nitrogen absorption and elimination will vary at each depth, which complicates the calculations necessary to avoid decompression sickness. The eRDPML (Extended Recreational Dive Planner Multilevel) allows divers to track their depth and time at each level to ensure they remain within safe no-decompression limits throughout the entire duration of the dive. By effectively managing the diver's pressure group and adapting to the various limits as the dive progresses, divers can safely enjoy the benefits of exploring different depths while minimizing the risk of experiencing negative effects from nitrogen loading. The other choices, while relevant to diving, do not specifically address the need for adjusting and managing pressure groups as it relates to multilevel diving. Thus, the focus on pressure group management is both a safety consideration and a central function of utilizing the eRDPML during multilevel dives.
