Learn Spanish (Latin America): El jefe está para un ataque de nervios. - The boss is about to have a nervous breakdown.

In this structure, estar para + noun describes someone's mood or state of being on the verge of something. It gives the sense that the boss is completely primed or "ready for" a breakdown, which translates smoothly to "about to have" one.

I learned that estar por means "to be about to". Why use para here instead of por?

You usually use estar por + infinitive for an action that is about to happen (like el tren está por salir). However, estar para is used to express a person's readiness, mood, or being on the verge of an emotional state. Additionally, estar para works perfectly with a noun, whereas estar por generally requires an infinitive verb.

Could I add a verb and say está para tener un ataque?

Yes, you could use the infinitive and say está para tener un ataque de nervios. But a great feature of estar para is that you can drop the verb and link directly to the noun. It makes the sentence punchier and is very common in conversational Spanish.

Is un ataque de nervios a serious medical condition here?

Not necessarily. While it can translate literally to "a nervous breakdown," Spanish speakers frequently use un ataque de nervios casually to mean a severe fit of stress, a panic attack, or just "losing it" at work.
