Poison bug

Sage Advice: You can check Poison basic rule in Player’s Handbook p.153 that only describes: “…the poison retains potency for 1 minute before drying.” In Dungeon Master’s Guide p.257 some poisons could be very lethal if last for 1 minute (10 rounds).

My advice is that applied poison last until the weapon strikes or 1 minute is passed.

If I use Ready to make an attack with a reaction, can I also take an associated bonus action e.g. Flury of Blows?
