Hope you/she can get some answers from the doctor. One thing that stood out in the original post — you say that she takes pills at the drop of a hat, yet she has not been taking aspirin. Is there any possibility that she does not view aspirin as "real medicine" and therefore does not think it’s as important as her other pills? Back in the olden days, aspirin was often seen as a low level pain reliever, with no particular value. When acetaminophen and particularly NSAIDs came along, these replaced aspirin in popular use for pain relief and fever reduction. The use of low-dose aspirin as a blood thinner is much newer.
This may not be relevant to OP's mom, but if there’s any possibility it is, please make sure her doc realizes this and can emphasize the value of taking it regularly. (Alternatively, the doc may want to switch her to a different blood thinner in light of the recent event.)
