To give abdominal thrusts to a responsive choking adult, what hand position is used?

To provide abdominal thrusts to a responsive choking adult, the correct hand position is just above the navel. This area is crucial because applying pressure here allows for effective thrusts that can dislodge a foreign object obstructing the airway. The upward thrusts generated by the hands positioned in this manner create a forceful movement against the diaphragm, which can help expel the object causing the choking.

Positioning the hands above the navel takes advantage of the anatomical structures in the abdomen, ensuring that the thrusts are directed at the diaphragm and that they effectively raise the pressure within the thoracic cavity to expel the blockage. Proper hand placement is essential; if the hands are positioned too low or too high, as might happen with some of the incorrect choices, the effectiveness of the maneuver would be compromised, potentially causing injury without addressing the choking hazard.
