- 1.PRAYER TO BE A NURSE To be a nurse is to walk with God, Along
thepath that our Master trod; To soothe the achingsof human pain,
To faithfully serve for littlegain, To lovingly do the kindly deed,
A cup ofwater to one in need, A tender hand on afevered brow, A
word of cheer to those livingnow; To reach the souls through its
bodys woeOh, this is the way that Jesus would go.Oh, white-capped
nurses with hearts sotrue, Our Great Physician is working
throughyou.

FiteAUTONOMIC NERVOUS SYSTEM AGENTS 3. PARASYMPATHETIC AND
SYMPATHETICNERVOUS SYSTEMS 4. ADRENERGIC AGONISTS Function of
adrenergics 5. ADRENERGIC AGONISTS (CONTD) Effects of adrenergic
receptor sites Alpha1receptors in Vascular tissuesstimulated =
Increasescardiac contractility, BP is increased, vasoconstriction,
circulation is improved Dilates pupils, decrease salivary gland
secretion Increase bladder & prostate contraction Alpha2 =
Inhibits norepinephrine release Promote vasodilation and decreased
BP DecreaseGI motility and tone 6. ADRENERGIC AGONISTS (CONTD)
Effects of adrenergic receptor sites Beta1 Found in the heart
Increases cardiac contractility, heart rate Increases BP by effects
on the kidneys renin secretion. Beta2 found primarily in the smooth
muscleof the lungs Bronchodilation Decrease Gastrointestinal, relax
uterine muscle Increases blood flow in skeletal muscles Increases
blood glucose because liver releases stored suger Dopaminergic
Receptor sites located in the renal system andthe real arteries are
dilated when the receptors are stimulated Vasodilation Increases
blood flow 7. ADRENERGICS AND DISEASEBeta Agonist are used to treat
asthma and chronic obstructive lung disease and manage
pregnancyBeta-1 are primarily used in heartBeta -2 Agonist
stimulate bronchodilatation in the treatment of lung disease. 8.
CLASSIFICATION OF ADRENERGICAGONISTS/SYMPATHOMIMETICS Direct-acting
- Endogenous Indirect-acting StimulatesEndogenous Release
Mixed-actingEphedrineEpinephrinePrototype Drug 9. CATECHOLAMINES
Chemical Structures of a substancethat can produce a
sympthomemticresponse Endogenous= norepinepherine epinepherine,
dopamine Exdogenous Catacholimines 10. EPINEPHRINE (ADRENALIN)
Nonselective Action Alpha1increases the blood pressure Beta1
increases heart rate Beta2 promotes bronchodilation
Pharmacodynamics: Frequentlyused in emergencies to treat
lifethreatening anaphylaxis IE BeeStings. It is also used as a
potentinotropic drug in a CODE. 11. ALBUTEROL (PROVENTIL) Selective
Actson beta2-adrenergic receptors Promotes bronchodilation Uses
Treatsbronchospasm, asthma,bronchitis, COPD Side effects/adverse
reactions Tremors, nervousness, restlessness Dizziness, reflex
tachycardia 12. Adrenergic AgonistNursing Process Assessment

13. ADRENERGIC BLOCKERS (ANTAGONIST) Block effects of adrenergic
agonistneurotransmitter Block alpha and beta receptor sites 1.
Directly by occupying receptors 2. Indirectly by inhibiting release
of neurotransmitters epinephrine and norepinephrine, dopamine 14.
ALPHA ADRENERGIC BLOCKERS Nonselective Acting Alpha 1 and Alpha 2
are selected Selective Blockers cause vasodilation, decreasesblood
pressure. Used to treat BPH and PVD(Raynauds Disease) 15.
BETA-ADRENERGIC BLOCKERS Beta-blockers DecreaseBP and Pulse
Nonselective beta blockers block1. Blocks beta1 = Decrease BP and
Pulse2. Blocks beta2 = Bronchostriction Uses Angina,
cardiacdysrhythmias, hypertension, heartfailure, migraine headache
prophelaxis 16. NONSELECTIVE BETA BLOCKERS Must be used with
extreme caution in COPDand Asthma patients. Although Propranolol is
used still used todayit is used sparingly because of the
multitudeof side effects. 17. BETA-ADRENERGIC BLOCKERS (CONTD)
Nonselective propranolol Contraindications COPD and Asthma Side
Effects Weightgain, impotence, decreased libido, Drug interactions
Decreased drug effects with NSAIDs, barbiturates, caffeine P R o T
O 18. ATENOLOL Beta Adrenergic blocker Contraindicated in Sinus
Bradycardia, Heartblock, bronchospasm Treat Hypertension, angina,
MI Side effects:Drawsiness, dizziness, depression, weakness, N/D/V
leg pain, sexual side effects Adverse Reaction:bradycardia,
hypotension, maskinghypoglycemia, 19. ATENOLOL Pharmacokinetics
