気分 ('mood, feeling, condition') is a key word for asking about someone's physical or emotional state. 気分はどう? is the everyday 'how are you feeling?' 尋ねる (literary register) is the attribution verb. Note two は in the sentence — the inner one belongs to the quoted clause, the outer to the main clause.
