Correct answer: E — Arrange urgent assessment of electrolyte and cardiac complications
The best answer is “Arrange urgent assessment of electrolyte and cardiac complications”. Hypokalaemia with QTc prolongation after recurrent vomiting can cause life-threatening arrhythmia regardless of BMI and requires urgent medical assessment and monitored correction. Fluoxetine and eating-disorder treatment may be appropriate after acute stability is established, but they do not treat the immediate electrolyte and cardiac risk.
