Guide
1. Receptors Norepinephrine-Adrenergic (adrenergic
comes from the word adrenalin)
Alpha 1-all sympathetic target organs ex-
cept the heart-constrict the blood vessels
and dilation of pupils
Alpha 2-Presynaptic adrenergic nerve ter-
minal-inhibits the release of norepineph-
rine
Beta 1-Heart and Kidneys (BETA 1-ONE
HEART)-increased heart rate and force of
contraction, release of renin
Beta 2-All sympathetic target organs-in-
hibits smooth muscle (BETA 2-TWO
LUNGS)
2. Beta blockers/olol's Beta-Adrenergic Blockers
Metoprolol/Lopressor ENDING OLOL
Beta Blockers are use with heart failure,
hypertension, angina and with myocardial
infarctions.
Action = Blocks Beta-Receptors in the heart
causing...
Decreases = HR, force of contraction, Rate
of atrioventricular (AV) conduction
SE = Bradycardia, lethargy, GI disturbance,
congestive heart failure, decrease BP, de-
pression

The beta blockers stop sympathetic ner-
vous system stimulation of the heart. Does
not allow the heart rate and blood pressure
to rise with stress thus lowering the oxygen

demand of the heart. It is very heart pro-
tective!
Will slow the heart rate and lower the blood
pressure
Can have beta 2 blockage with larger dos-
es-will constrict the bronchioles-watch for
clients with known COPD, Asthma
Nursing Interventions
Check pulse-needs to be 60 or above
Check blood pressure-if hypotensive do
not give (Systolic below 100 is a good rule
of thumb I go by)
Monitor for sexual dysfunction-impotence
for men-a good reason for non-compli-
ance
Drowsiness/Fatigue-operating heavy ma-
chinery, driving could put client at risk
Insomnia-
Contraindicated with Heart Blocks, Brady-
cardia, Worsening Heart Failure
Increases Hypoglycemic ettect of In-
sulin-monitor blood sugars and for hy-
poglycemia, may need to lower insulin
dosage
Beta Blockers have to be weaned slow-
ly to prevent rebound hypertension and
tachycardia-if a client wants to stop his
beta-blocker they need to contract their
physician
3. CCB,/calcium channel blockers

Nifedipine/Adalat/Procardia/Norvasc-con-
trols blood vessels
Diltiazem/Cardizem
Verapamil/Calan/Isoptin/Verelan-controls
heart rate and blood vessels
Angina/Raynaud's/Vasospastic Angi-
na/Atrial Arrhythmia's
Blocks calcium channels in the myocardial
and vascular smooth muscles, decreases
the contraction of smooth muscle-relaxes
the arteries-vasodilation. Blocking of calci-
um channels in the SA and AV node-Slows
conduction through the SA and AV node.
Decreases the force of contraction slows
heart rate
Grapefruit juice may increase absorption
of nifedipine
Side Ettects: Relaxes smooth muscle and
cardiac muscle-
Headache
Dizziness-Take lying, sitting and standing
B/P, educate client to sit and stand slowly
Peripheral edema-assess for edema, mon-
itor for worsening (diuretic)
Flushing
Reflex tachycardia-monitor for elevated
heart rate (may need a BB)
Constipation-increase fibers and fluids (if
