Question

A patient has a high level of mast cell activity, dilation of blood vessels, and acute drop in blood pressure. Which condition is most consistent with these symptoms?

A. an autoimmune disease

B. a typical skin allergy (contact dermatitis) that can be treated by antihistamines

C. anaphylactic shock immediately following exposure to an allergen

D. an organ transplant, such as a skin graft

Answer 1

The symptoms described are most consistent with anaphylactic shock, a severe allergic reaction that can be life-threatening if not treated promptly.

Step-by-step explanation:

The symptoms of high mast cell activity, dilation of blood vessels, and acute drop in blood pressure are most consistent with anaphylactic shock that occurs immediately following exposure to an allergen.

Anaphylactic shock is a severe allergic reaction that can be life-threatening if not treated promptly.

During anaphylactic shock, mast cells release histamine and other inflammatory chemicals, causing blood vessels to dilate and blood pressure to drop.

Treatment for anaphylactic shock typically involves the use of epinephrine to counteract the effects of the allergic reaction and stabilize blood pressure.
