OP here. I’ve overwhelmed by all the helpful comments. Thank you so much. My mom is doing better. She’s not strong enough for the heart surgery yet, but she’s well enough to be refusing all the hospital food.

They told me to bring her whatever she’ll eat at this point, so I’m having fun hitting up her favorite spots.
My siblings and I have totally joked about this hopefully being a fireable offense at her office. My parents are comfortable and she is well past retirement age (70s), so it wouldn’t be a financial issue, but her identity is wrapped up in her work and I worry what she would do with herself without the job. I suggested she volunteered with a small business group or a group that helps non-profits get started. I think the issue is that she assumes that at her age, no one will want her.
I didn’t even think about the fact that they did send her flowers. Jerks!
Her boss def was talking business. There is a religious affiliation to the charity and if the boss was there to support, I think they would have been praying.
Anyway, thanks again for all the support. DCUM has its moments, but you all have had some good points that made me think.
