MEDICAL-SURGICAL NURSINGNERVOUS SYSTEM
Overview of structures and functions:
Central Nervous SystemBrainSpinal Cord
Peripheral Nervous SystemCranial NervesSpinal Nerves
Autonomic Nervous SystemSympathetic nervous systemParasympathetic nervous system
AUTONOMIC NERVOUS SYSTEM
Sympathetic Nervous System(ADRENERGIC)
Parasympathetic NervousSystem(CHOLINERGIC, VAGAL,SYMPATHOLYTIC)
EFFECTS OF SNS- Dilation of pupils(mydriasis) inorder to be aware.- Dry mouth (thickened saliva).- Increase BP and Heart Rate.- Bronchodilation, Increase RR
- Constipation.- Urinary Retention.- Increase blood supply to brain,heart and skeletal
muscles.- SNSI. Adrenergic Agents- Give Epinephrine.
Signs andSymptoms:
- SNS
Contraindication:- Contraindicated to patientssuffering from COPD(Broncholitis, Bronchoectasis,Emphysema, Asthma).II. Beta-adrenergic BlockingAgents- Also called Beta-blockers.-All ending with lol- Propranolol, Atenelol,Metoprolol.
Effects of Beta-blockersB roncho spasmE licits a decrease inmyocardial contraction.T reats hypertension.A V conduction slows down.
Should be given to patientswith Angina Pectoris,Myocardial Infarction,Hypertension.ANTI- HYPERTENSIVE
AGENTS1. Beta-blockerslol2. Ace Inhibitors Angiotensin,pril (Captopril,Enalapril)3. Calcium AntagonistNifedipine (Calcibloc)
In chronic cases of arrhythmiagiveLidocaine(Xylocaine)
- Involved in fight or aggressionresponse.- Release of Norepinephrine(cathecolamines)from adrenal glands and
causes
vasoconstriction.- Increase all bodily activityexcept GIT- Involved in fight or withdrawalresponse.- Release of Acetylcholine.- Decreases all bodily activitiesexcept GIT.EFFECTS OF PNS- Constriction of pupils(meiosis).- Increase salivation.- Decrease BP and Heart Rate.- Bronchoconstriction, DecreaseRR.- Diarrhea- Urinary frequency.I. Cholinergic Agents- Mestinon, Neostigmine.Side Effects- PNSII. Anti-cholinergic Agents- To counter cholinergic agents.- Atropine SulfateSide Effects- SNS
CENTRAL NERVOUS SYSTEMBrain and Spinal Cord.
I. CELLSA. NEURONS
Basic cells for nerve impulse and conduction.
PROPERTIESExcitability ability of neuron to be affected by changes in externalenvironment.Conductivity ability of neuron to transmit a wave of excitation fromone cell to another.Permanent Cell once destroyed not capable of regeneration.TYPES OF CELLS BASED ON REGENERATIVE CAPACITY1. Labile
Capable of regeneration.Epidermal cells, GIT cells, GUT cells, cells of lungs.
2. StableCapable of regeneration with limited time, survival period.Kidney cells, Liver cells, Salivary cells, pancreas.
