Write answer in between .Q:A 7-year-old boy is rushed to the urgent care department from a friends birthday party with breathing trouble. He is immediately placed on supplemental oxygen therapy. The patients father explains that peanut butter treats were served at the event, but he reported not having witnessed his son actually eat one. During the party, the patient approached his father with facial flushing, difficulty breathing, and itching of his face and neck. The patient was born at 40 weeks gestation via spontaneous vaginal delivery. He has met all age-related developmental milestones and is fully vaccinated. His past medical history is significant for peanut allergy and asthma. He carries an emergency inhaler. Family history is noncontributory. The patients vitals signs include a blood pressure of 11085 mm Hg, a heart rate of 110min, a respiratory rate of 25min, and a temperature of 37.2C 99.0F. Physical examination reveals severe facial edema and severe audible stridor in both lungs. Which of the following types of hypersensitivity reaction is the most likely in this patient?? A: Type 1anaphylactic hypersensitivity reaction, B: Type 2cytotoxic hypersensitivity reaction, C: Type 3immune complex-mediated hypersensitivity reaction, D: Type 4cell-mediated delayed hypersensitivity reaction, E: Mixed anaphylactic and cytotoxic hypersensitivity reaction,  <response>: This is a clinical vignette describing a 7-year-old boy with a known peanut allergy who develops acute symptoms of facial flushing, difficulty breathing, and itching after possible peanut exposure at a party. The symptoms described are consistent with an anaphylactic reaction, likely triggered by exposure to peanut allergen in a sensitized individual. The key features pointing to an IgE-mediated type 1 hypersensitivity reaction are:- Known history of peanut allergy - Acute onset of symptoms after possible peanut exposure- Symptoms of facial flushing, respiratory distress, and itching suggestive of anaphylaxis- Physical exam showing facial edema and stridorThe other answer choices describing cytotoxic, immune complex, delayed hypersensitivity or mixed reactions do not fit with the clinical scenario described.A: Type 1anaphylactic hypersensitivity reaction
