What sign indicates that a first responder should not perform a finger sweep in case of an obstructed airway?

The correct response highlights that if the airway remains obstructed, performing a finger sweep may not be appropriate. A finger sweep is a technique intended to remove a visible obstruction from the mouth; however, if the airway is still blocked, this action may push the object further down the throat, worsening the blockage rather than alleviating it. First responders must assess the situation carefully and determine if the obstruction can be safely removed without causing further harm.

In this context, while an unconscious victim can lead to a critical situation, it doesn't necessarily mean a finger sweep should always be avoided. Making sounds indicates that there may still be some air exchange, suggesting that the airway is not fully obstructed, thus potentially allowing for other interventions. A clear airway also indicates that there’s no obstruction, making the finger sweep unnecessary. Hence, the focus on an obstructed airway serves as the critical indicator for whether to attempt a finger sweep.
