Understanding Anaphylactic Shock

What is the primary cause of anaphylactic shock?

• Severe allergic reaction

• Dehydration

• Viral infection

• Bacterial infection

Which cells are responsible for creating antibodies in response to an allergen?

• T cells

• B cells

• Mast cells

• Red blood cells

What is the role of IgE in immunologic anaphylaxis?

• It destroys allergens directly

• It docks onto mast cells

• It produces histamine

• It dilates blood vessels

What is the function of cytokines released by mast cells?

• To decrease oxygenation of tissues

• To produce antibodies

• To communicate with other white blood cells

• To increase blood pressure

How does histamine affect blood vessels during an allergic reaction?

• It constricts them

• It makes them leaky

• It strengthens them

• It reduces their diameter

What differentiates non-immunologic anaphylaxis from immunologic anaphylaxis?

• It directly targets mast cell receptors

• It involves IgE

• It does not involve histamine

• It is caused by bacteria

Which symptom is most serious in anaphylactic shock due to histamine release?

• Runny nose

• Bronchospasms

• Skin flushing

• Itchiness

What is the first step in treating a patient with anaphylactic shock?

• Providing antihistamines

• Establishing the airway

• Ordering lab tests

• Administering antibiotics

How does epinephrine help in treating anaphylactic shock?

• It dilates blood vessels

• It reduces oxygen levels

• It constricts blood vessels and opens airways

• It increases histamine production

What is the mainstay of treatment for anaphylactic shock?

• Antibiotics and oxygen

• Epinephrine and IV fluids

• Antihistamines and rest

• Surgery and blood transfusion
