Answer:
Perform the heimlich maneuver
Explanation:
The heimlich maneuver is how you can get the grape out of being lodged in the person's throat.
If the person is collapsed it is hard to make them stand up to perform this so you would lie them on their back, kneel over them for better position, place your hand (or heel of hand) on their abdomen slightly above their naval area, then placing the other hand on top of that hand making quick and upward thrusts to dislodge the grape, then if you can get it out perform CPR if you can to help with restoring oxygen.
