Correct answer: B — Give high-flow oxygen, keep supine and arrange hyperbaric advice/transfer
Neurological symptoms after rapid ascent suggest decompression illness requiring high-flow oxygen and urgent hyperbaric advice. Pulse oximetry may be normal and does not exclude decompression injury. Nitrous oxide and altitude exposure can worsen inert gas problems.
