Which of the following is a sign or symptom of a patient experiencing anaphylactic shock?

Anaphylactic shock is a severe, potentially life-threatening allergic reaction characterized by a rapid onset of symptoms affecting multiple body systems. The correct answer includes all the listed symptoms because they are all common indicators of anaphylaxis.

Hives are raised, itchy welts on the skin that often appear quickly during an allergic reaction and can be a first sign of impending anaphylaxis. Difficulty breathing is a critical symptom that arises due to airway constriction and swelling, making it hard for the patient to breathe adequately. Swelling of the face, lips, or tongue, known as angioedema, is particularly concerning in anaphylaxis as it can obstruct the airway and lead to respiratory failure.

The presence of all these signs and symptoms together points towards the severity of anaphylactic shock, necessitating immediate medical attention. Recognizing the combination of these symptoms is vital for emergency responders to initiate the proper course of action, such as administering epinephrine and ensuring the patient's airway is protected.
