Correct Answer is B
Explanation
A. Local reaction: A local reaction is limited to a small area, such as redness, swelling, or itching at the injection site. It is not systemic or life-threatening and does not compromise airway, circulation, or organ function.
B. Anaphylaxis: Anaphylaxis is a severe, systemic, IgE-mediated allergic reaction that can rapidly involve multiple organ systems, including respiratory distress, hypotension, and cardiovascular collapse. Immediate recognition and treatment with epinephrine and supportive care are critical to prevent death.
C. Inflammation: Inflammation is a nonspecific immune response characterized by redness, swelling, heat, pain, and loss of function. It can occur in response to infection, injury, or irritation, but it is not inherently life-threatening.
D. Sensitivity: Sensitivity refers to an exaggerated immune response to a substance, which may cause mild to moderate symptoms such as rash or itching. It does not describe the acute, life-threatening systemic reaction seen in anaphylaxis.
