Clutching the throat with one or both hands
B
Placing hands on the chest
C
Raising both arms above the head
D
Covering the mouth with both hands
Verified step by step guidance1
Understand the context of the question: The universal sign for choking is a non-verbal gesture used to indicate distress when someone is unable to speak due to airway obstruction.
Recall the anatomy of the airway: Choking occurs when the airway is blocked, preventing airflow to the lungs. This can lead to difficulty breathing and an inability to speak or make sounds.
Consider the physical response: When someone is choking, they instinctively clutch their throat with one or both hands to signal that their airway is obstructed. This gesture is universally recognized as the sign for choking.
Eliminate incorrect options: Placing hands on the chest, raising arms above the head, or covering the mouth with both hands are not associated with choking and do not effectively communicate airway distress.
Conclude that the correct answer is clutching the throat with one or both hands, as this is the universally recognized sign for choking.
