A. Allergic reactions can occur anytime a patient is exposed to a drug.
B. Histamine release can cause vasodilation and hypotension.
C. True anaphylaxis involves IgE antibodies.
D. Epinephrine acts to destabilize mast cells, affecting their ability to degranulate.
E. Vasopressin is useful in treating the hypotension associated with anaphylaxis if the patient is unresponsive to epinephrine.

Answer 1

The false statement in the given options is that epinephrine acts to destabilize mast cells, affecting their ability to degranulate.

Step-by-step explanation:

The false statement in the given options is D. Epinephrine acts to destabilize mast cells, affecting their ability to degranulate. In fact, epinephrine acts to stabilize mast cells and prevent their degranulation. Epinephrine is used to counteract the effects of anaphylaxis by raising blood pressure, relaxing bronchial smooth muscle, and reducing swelling. Therefore, option D is the incorrect statement out of the choices given.
