While dining out in a restaurant a man suddenly chokes on a piece of meat. The waitress is also a student nurse and comes to the man's aid. She asks him if he can talk. The man responds by shaking his head no and grabbing at his neck. What is the significance of the man's inability to talk?
What will be an ideal response?
Speech involves the intermittent release of expired air and opening and closing of the glottis. Because the man is unable to speak, this indicates that he is choking on a piece of food that suddenly closed off the glottis in the larynx.
