Systemic reaction classification example post-injection with vomiting.
Systemic reaction is the correct classification for the scenario described, where the patient starts vomiting following an intramuscular injection. This indicates a widespread response throughout the body, possibly indicating an anaphylactic reaction to the injection.
Anaphylactic reactions involve severe immune system responses to antigens, leading to potentially life-threatening symptoms such as vomiting, difficulty in breathing, and even death. In this case, the vomiting post-injection suggests a systemic response rather than a local adverse reaction.
