Correct answer: D — Refer urgently for assessment of possible lithium toxicity

Vomiting, coarse tremor, and ataxia are concerning for lithium toxicity. NSAIDs can increase lithium levels, and urgent blood level, renal function, and clinical assessment are needed. Symptomatic over-the-counter treatment would not manage the potentially serious toxicity.
