Which medication will most likely be administered to a client experiencing anaphylaxis?

Epinephrine

Which would the nurse expect to be given to a client experiencing acute bronchospasm?

The adrenergic branch of the autonomic nervous system is also known by which name?

Sympathomimetics

A client is in shock and is receiving dopamine. The nurse knows that the proper way dopamine should be given is by what method?

Via an electric infusion pump, by itself, and titrated to desired systolic blood pressure
