Answer:
If a person is showing symptoms of anaphylaxis, the first step that should be taken is to administer emergency epinephrine (adrenaline) if it is available. Anaphylaxis is a severe allergic reaction that can be life-threatening. The symptoms include difficulty breathing, hives, swelling of the face, and rapid pulse. If left untreated, anaphylaxis can lead to shock, cardiac arrest, and death. Epinephrine is the first-line treatment for anaphylaxis and should be administered as soon as possible. This can be done by injecting an epinephrine auto-injector into the muscle of the thigh. If the person does not have an epinephrine auto-injector, emergency medical services should be called immediately.
