Final answer:
A conscious choking victim cannot speak or cry out, has labored breathing, and cannot cough effectively.
Step-by-step explanation:
When identifying what three things a conscious choking victim cannot do, it is important to recognize the signs of a blocked airway. Firstly, the victim cannot speak or cry out, due to the obstruction in their throat. Secondly, they may demonstrate labored breathing, which can include gasping or wheezing sounds as they struggle to draw air through the blocked passageway. Lastly, due to the severity of the blockage, they will not be able to cough effectively, if at all, in an attempt to dislodge the object.
In cases of choking, quick actions such as back slaps or the Heimlich maneuver may be necessary to help clear the victim's airway. It’s also important to remember that in cases of drowning, a person’s instincts might prevent them from calling out for help, or their actions underwater may not signal distress as one may typically expect.
