adrenergic aka
Sympathetic
fight or flight reactions are from the
sympathetic nervous system
Receptors in Sympathetic NS

Nursing Considerations when dealing with Sympathetic agonists & blockers
-Pt PMH/ current diagnosis
-Pt allergy
-Checking heart rate and BP prior to administering
Prior to given beta blockers, heart rate should be ____
