The health care provider prescribes epinephrine (adrenalin) to a client who was stung by several wasps 30 minutes ago. The nurse knows that the primary purpose of this medication for this client is to:

1. Stop the systemic release of histamine produced by the mast cells.

2. Counteract the formation of antibodies in response to an invading antigen.

3. Increase the number of white blood cells produced to fight the primary invader.

4. Increase a declining blood pressure and dilate constricting bronchi associated with anaphylaxis.
