Final answer:
To assist a 2-year-old child who suddenly appears cyanotic and unable to speak after playing with a small toy, one should perform abdominal thrusts if choking is suspected, clear the airway, and if necessary, give oxygen and seek medical transportation.
Step-by-step explanation:
The sudden appearance of cyanosis (bluish discoloration of the skin) and inability to speak in a 2-year-old child after playing with a small toy could indicate a possible choking incident. In such cases, immediately giving abdominal thrusts (also known as the Heimlich maneuver) can help expel the object causing the blockage. It is crucial to check and clear the airway before performing any other intervention. If the child is not responsive or shows signs of respiratory distress, giving oxygen and seeking medical transportation is recommended.
