Final answer:
The licensed practical nurse would most likely perform the Heimlich maneuver to help dislodge the obstructing object from the woman's airway.
Step-by-step explanation:
In this scenario, the woman is choking on a piece of chicken. The licensed practical nurse sitting at the next table would most likely perform the Heimlich maneuver to help dislodge the obstructing object from the woman's airway. The Heimlich maneuver involves standing behind the choking person, placing a fist just above the navel, grasping the fist with the other hand, and exerting firm upward pressure to force the object out.
