If you die in minecraft and you dont hit respawn is the chunk still loaded if you just sit at the screen that says "respawn"
Yes, as long as you are in the death screen. It keeps those chunks loaded (meaning your items could disappear) - so I would go ahead and click the button sooner than later
My own advice? Hit that button, get to the spawn, and run to that place like 50 charged creepers are chasing you. Unless you already have a spawn point nearby, then just cross out step 2.
