Appendix 5A in the US Navy Dive Manual CHANGE A covers which examination?

• A. Decompression protocol for surface interval
• B. Neurological Examination
• C. Cardiovascular Assessment
• D. Respiratory Evaluation

Answer: (B)

The main idea here is the neurological evaluation used for divers. Appendix 5A Change A in the US Navy Dive Manual sets out a standard neurological examination that is used to screen a diver’s nervous system before diving. This matters because neurological status can reveal conditions or deficits that could be dangerous under diving conditions, such as effects of prior brain injury, stroke, seizures, or other nervous system issues that could be worsened by pressure changes or decompression events.

A typical neuro exam covered in this context includes checking mental status, cranial nerves, motor strength, sensory function, coordination, and gait, along with reflexes. Establishing baseline neurological function helps ensure a diver is fit to dive and helps identify any red flags that require further medical evaluation or avoidance of diving.

Other options refer to different areas (decompression protocols, cardiovascular assessment, respiratory evaluation) and describe either procedures or assessments of other body systems, not the focused neurological examination described in this appendix.
