Answer: Lena should learn a safety training classes for babysitting.
Step-by-step explanation:
Lena's ability to help a child who is choking on his food likely stems from knowledge of the Heimlich maneuver. The Heimlich maneuver is a reliable method for assisting a person who is choking and can be lifesaving in such situations. Here's a step-by-step guide on how to perform the Heimlich maneuver on a choking child:Stand or kneel behind the child and wrap your arms around their waist. Ensure that you are positioned behind the child so you can provide effective support. Make a fist with one hand and place the thumb side against the child's abdomen, just above the navel but below the ribcage.Grasp your fist with your other hand and press it inward and upward with a quick, forceful movement. This action should be similar to trying to lift the child upward and inward. Repeat the thrusts until the object causing the choking is dislodged, and the child can breathe or cough effectively.If the child becomes unconscious, lower him gently to the ground and begin CPR (cardiopulmonary resuscitation) if necessary. In such a case, call for emergency medical assistance immediately.It's important to note that the Heimlich maneuver should only be performed on a choking person who is conscious. If the child is conscious but not effectively coughing or breathing, the Heimlich maneuver can help dislodge the obstructing object.
However, if the child is unable to breathe, becomes unconscious, or the Heimlich maneuver doesn't work, immediate emergency medical help should be sought. Knowing how to perform this maneuver and having the confidence to use it in emergencies can be crucial in saving a person's life. It is always best to learn and practice these techniques under the guidance of a certified first aid instructor.
