Correct answer: B — Start antiviral therapy and supportive oxygen

Start antiviral therapy and supportive oxygen is the best answer because hospitalised influenza with pneumonia and hypoxia should receive antiviral treatment as well as supportive care. Give activated charcoal within one hour is plausible, but it is less appropriate for the physiology or timing described in this stem. The other distractors either fit a neighbouring presentation, delay definitive treatment, or miss the key immediate risk. Clinical pearl: Antivirals are not limited to patients presenting within 48 hours when illness is severe or hospitalised.
