Written Lifeguarding Practice Test

When giving abdominal thrusts to an adult who is choking, where should you position your fist?

1. In the center of the breastbone

2. In the middle of the abdomen, just above the navel

3. In the middle of the abdomen, just below the navel

4. On the rib cage

The correct answer is: In the center of the breastbone

When giving abdominal thrusts to an adult who is choking, your fist should be positioned in the center of the breastbone. This ensures that enough pressure is applied to the diaphragm to dislodge the object blocking the airway. Option B is incorrect because it is too low and could potentially cause harm to the navel and organs below it. Option C is also incorrect because it is too close to the navel and may not effectively push up on the diaphragm. Option D is incorrect because ribs may break under the pressure of the thrusts and could cause further injury to the choking adult. Placing your fist in the center of the breastbone is the most effective and safest way to perform abdominal thrusts for a choking adult.
