Answer:
Options A and B, back blows and abdominal thrusts
Explanation:
When a person is choking on a foreign object, the first aid that must be administered to dislodge the object consists of back blows and abdominal thrusts.
First, assess if the person is coughing. If they are coughing, they may be able to forcefully dislodge the item themselves. If they cannot cough the item up, it is time to render aid.
Standing behind the adult, the person assisting will start by placing their non-dominant hand on the adult's chest to brace them and support their weight. Then, the assisting person will deliver five forceful back blows with the palm of their dominant hand between the adult's shoulder blades.
After, if the item is still obstructing the airway, the assisting person will perform what is known as the Heimlich maneuver. While still behind the adult, make a fist with the dominant hand placing the distal end of their metacarpal that makes up the thumb into the adult's navel. Then, use the other hand to brace by firmly grasping the ulnar side of the fist. The assisting person will now deliver five forceful abdominal thrusts.
This process repeats, cycling between back blows and abdominal thrusts, until the object is dislodged.
Why Not Other Choices:
The adult is still responsive, meaning they currently have enough oxygen in circulation to remain conscious. Delivering breaths at this time may further lodge the item, the opposite of what is intended with first aid. Also because they are responsive, cardiopulmonary resuscitation (CPR) is contraindicated; the priority in this situation is the adult's airway rather than their breathing or circulation. Lastly, finger sweeps only indicated if the item can be clearly visualized in the choking person's throat; blindly finger sweeping can cause further blockage by physically pushing the obstruction deeper into the person's airway.
