A nurse in a long-term care facility is assisting a client with eating during mealtime and recognizes another client indicating he is choking. Which of the following situations requires the nurse to perform the Heimlich maneuver?

Choice A reason: A client who is coughing is still able to move air and should be encouraged to continue coughing to clear the obstruction. Choice B reason: Inability to make sounds indicates a complete airway obstruction, requiring immediate intervention with the Heimlich maneuver. Choice C reason: Inspiratory stridor suggests partial obstruction. While concerning, it does not yet warrant abdominal thrusts unless it progresses. Choice D reason: Whispering indicates some airflow is present. Heimlich is reserved for cases with no air movement or sound.
