A child is brought to the emergency room with symptoms of anaphylactic shock. Which of the following cues would be most indicative of anaphylactic shock?

The correct answer is B: Wheezing and difficulty breathing. In anaphylactic shock, the body has a severe allergic reaction, leading to airway constriction and difficulty breathing. Wheezing is caused by the narrowing of the air passages. This is a critical sign of anaphylactic shock as it indicates a potential life-threatening situation requiring immediate intervention, such as administering epinephrine. The other choices are not specific to anaphylactic shock. Nausea and vomiting (A) can occur but are not unique to anaphylaxis. Fever and chills (C) are more likely indicative of an infection. Hives and itching (D) are common symptoms of an allergic reaction but may not always accompany anaphylactic shock.
