Adrenergic drugs produce effects similar to those of the ___________ nervous system.

• Central

• Somatic

• Sympathetic

• Parasympathetic

The nurse is reviewing sympathetic nervous system agonists. Adrenergic drugs, such as albuterol (Proventil) inhalation, stimulate beta2-adrenergic receptors and cause:

• relaxation of the bronchi

• bronchoconstriction

• decreased heart rate

Which is an effect of adrenergic drugs

• increased heart rate

• constriction of bronchioles

• constricted pupils

The sympathetic nervous system

• is the fight or flight system

• arthritis

• hypertension

• gout

Beta-blockers are given for an MI because

• they inhibit stimulation from circulating catecholamines

• they protect the heart from further damage

• they decrease the work load of the heart

• they cause vasoconstriction

Precautions of adrenergic blockers include

• change positions slowly

• avoid hot tubs or saunas
