Correct answer: A — Arrange immediate descent, give oxygen and consider appropriate drug therapy.

High-altitude cerebral and pulmonary oedema are life-threatening, and the single most important intervention is immediate descent, supported by oxygen and adjuncts such as dexamethasone or nifedipine where available. Continued ascent or waiting at altitude can be fatal. Sedation may mask deterioration and depress respiration.
