Adrenergic Antagonists

Question 1

Adrenergic Antagonists- block alpha 1 & beta 1 receptor sites (ex: Prazosin)

Answer 1

Alpha 1:

Drugs in adrenergic antagonist class: end in “sin”

Question 2

Adrenergic Antagonists- beta 1 (ex: atenolol)
drugs in this class end in "lol"

Answer 2

beta 1 (ex: atenolol)
drugs in this class end in "lol"
these drugs work on heart & vessels

Question 3

Adrenergic antagonists:
Beta 1 Blockers
Action:

Answer 3

Block beta adrenergic receptor sites
decrease most of epinephrine
suppress the renin-angiotensin-aldolsterone system (RAAS)
beta 1= 1 heart- affects heart
beta 2= 1 lung- affects lungs

masking of hypoglycemia

Question 7

Adrenergic Antagonists- Beta 1 blocker

Contraindications:

Answer 7

heart block

asthma
pregnancy

Question 8

Adrenergic Antagonists- Beta 1 blocker

Interactions:

Answer 8

decreased effect w/ NSAIDs
increased effect w/ other antihypertensives/antidysrhythmics
increased R/F hypoglycemia w/ insulin & sulfonylureas; masks sxs

Question 9

Nursing Process for BB

Answer 9

Assess: monitor V.S. prior to admin drugs
check other meds pt is taking
pt health hx
Nursing Interventions: V.S. b/w doses, esp BP/HR (<60: bradycardia- report to provider)
report S.E.
pt safety d/t drowsiness
EKG prior to giving cardiac meds
don’t give to cardiac pts
don’t give to asthma pts- d/t constricts bronchioles
Pt Teaching:
Take same time daily; do NOT abruptly stop taking- d/t rebound effect
Take pulse prior to taking meds- hold for HR < 60 & report to physician
Pt needs to get up slowly.
report S.E./Adverse reactions
