WEEK 1 - PRINCIPLES OF PRE OPERATIVE CARE
Health (1946) is a state of complete physical, mental and social wellbeing and notmerely the absence of disease or infirmity.
Principles of effective learning allows the learner to direct the direct learning process-get to know other peoples perspective
Surgery is defined as the art and science of treating disease, injuries and deformities byoperation and instrumentation. It is performed for the following purposes
PARU Post anaesthetic recovery unit
PERI operative care - intervention to provide care prior to or during and immediatelyafter surgery
PRE operative care the time consent form are sign, assessment and observations are
taken and premedication has been administered.
Intra operative surgical phase Care of the pt during surgery requires carefulpreparation and knowledge of the events that occur during the surgical
procedure.Categories of surgical procedures
Urgency of the procedure
Elective surgery collection base on pts choiceUrgent require prompting
Emergency immediate to prevent life
Degree of risk
Minor less risk / involves minimal alteration in body parts; often designed to correctdeformities.
Major organ transplant or cardiac surgery /involves extended reconstruction oralteration in body part
Reason of surgery
- Diagnostic- diagnos/assess- Currative repair or remove
- Palliave pain relief, make the pt comfortable
- Preventative prevent illness
- Exploration surgical investigation- Cosmetic change personal apperance
Extend of surgery
- Anatomic location body and organ parts- Simple
- Radical
Common surgical suffexis- Supra - above
- Arthro related to the joints
- Myo related to mucle tissue
- Neuro related to nerves

- Thorac related to chest
- Abdomino related to abdominal
Why is a patient required to be nil by mouth (NBM) prior tosurgery
- so the risk of vomiting and aspirating emesis during the
surgery are reduced.- General anesthetics typically cause slowing ofgastrointestinal peristalsis
- Patients are only allowed to take a sip of water with aspecific medication (anticoagulants, cardiovascularmedications & anticonvulsants)
- Normal mechanisms for controlling fluid and electrolyebalance, inc respiration, digestion, circulation andelimination are disturbed
- Surgical procedure may cause extensive losses of bloodand other body fluids. The surgical stress response
aggravates any fluid and electrolyte imbalance.Why would a patient require bowel preparation prior to surgeryand how would this be undertaken?
- Empty bowel reduces risk of injury to the intestines andprevents contamination of the operative wound in caseas part of the bowel is incised or opened accidentally, orif a colon is planned.
Common surgical suffixesOma - tumour/swellingItis - inflammation (tonsilitis)Oscopy - looking into (gastroscopy)
Ostomy - making an opening (colostomy)Otomy - cutting into (tracheotomy)Plasty - repair/restore (mammoplasty)Orrhophy - repairing part or suturing (herniorrhaphy)Ectomy - removal of (appendictomy)
Preoperative checklist & consent verification
Pre operative medicationBenzodiapines reduces anxiety, induced sedation &
amnesiaOpiates relax discomfort during preoperative procedure
Histamine increase gastric ph, Decrease gastric volumeAnticholinergies decrease oral and resp. secretion and
preventbradycardia (low heart rate)
Antacids increase gastric phSedative relax ptProphylactic prevent infection

WEEK 2 - PRINCIPLES OF INTRA OPERATIVE NURSING CARE
INTRAOPERATIVE PHASE - is from the patient is received in the operatingroom until admitted to the recovery room.Phases of interoperative period
Preoperative holding area
Admission to the operating roomIntroduction to anaestheticPositioning for surgerySurgeryTransfer to recovery
Introduction of anaesthesiaGeneral - is a loss of sensation with loss of consciousness, skeletal
muscle relaxation, analgesic andelimination of the somatic, automatic and endocrineresponses, inc coughing, gagging, vomiting and
sympathetic nervous system responsiveness
Regional - is the loss of sensation to a region of the body withoutloss of consciousness when a specific nerve orgroup of nerves is blocked with the administration of alocal anaesthetic (spinal, epidural or peripheral nerveblock)
Local - is the loss of sensation without loss of consciousness. It canbe induced topically or via infiltration intracutaneously(within the skin) or subcutaneously (placed justbeneath the skin)
Concious sendation - (twilight sleep) is a minimal depressed levelof conciousness with maintenance of the patients
protective airway reflexes.- Primary goal is to reduce patients anxiety and discomfort
and to facilitate cooperation- Conscious sedation retains the patients ability to maintain
their own airway and to respond appropriately to verbalcommands, yet achieve a level of emotional andphysical acceptance of a painful procedure (eg. colonscopy)Documentation - Must be complete, accurate & comprehensive

Potential intraoperative complicationAnaphylaxis - is a severe allergic reaction
- causes hypotension, tachycardia, broncospasm andpossibly pulmonary oedema
Malignant hyperthermia (MH) - is a rare metabolic disease
characterized by hyperthermia with rigity of skeletalmuscles that can result in death. It occurs with peopleexposed to certain anaesthetic agents.
Hypoxia - deficiency in the amount of oxygen reaching to tissueExcessive blood loss bleeding and or haemorrhagingHypothermia - low body temperature to 34*. it is most common
among babies and elderly peopleGerontological considerations - older people demonstrate a unique
responses to medication.- Physiological changes in ageing may alter the pts responsenot only to the anaesthetic, but also to blood and fluid loss
and replacement, hypothermia, pain and the tolerance ofthe surgical procedure and positioning.- Decrease in the ability to communicate, follow directions
due to altered vision or hearing therefore conciseand clear communication is needed.
- Due to decreased ability to perceive discomfort or pressureon vulnerable areas and loss of skin elasticity
Injury-Intraoperative environment - divided into four
Unrestricted, semi restricted, restricted and transitionPrinciple of Intraoperative phases - safety, assessment, accuracy,
communication, documentation, outcomes
Routine social/hand wash routine - 15 to 30 secondsSurgical hand wash routine - 5 minutes after every invasive procedureeg. catheterizingDifferent handover - verbal, written and taped
WEEK 3 - PRINCIPLES OF ASEPSIS
Asepsis - is defined as the absence of pathogenic microorganisms.- It is also refers to practices that keep a patient as free
from organism as possibleTypes of aseptic technique
Clean/medical technique - no touch technique or clean technique- involves procedure use to reduce and prevent the spread
of microorganisms e.g. hand washing, use of PPESurgical technique - involves procedure used to eliminate all
microorganism, incl. pathogens and spores, from anobject or area by creating a sterile field. Such as an area or
-

5/25
400749 - NURSING & HEALTH BREAKDOWN SPRING REVISION
subject is contaminated if touched by any object thatis not sterile.
Sterile technique - involves complete elimination or destruction ofall microorganisms incl. spores it can be done bysteam under pressure ethylene oxide gas (ETO), hydrogen
peroxide plasma and chemicals such as periacetic acid .Disinfection - a process that kills or in actives microorganisms thatwill reduce to acceptable method. Such as, certain bacterialmay survive and germinate which could lead tocontamination therefore care must be taken to ensureall residual are removed prior to use. Alcohol, chlorines,
glutaraldehydes and phenol but can also cause toxic to tissue.
Methods of disinfection/sterilization - Heat/ Filtration/ Chemicaldisinfectants & Antiseptics/ Alcohol
Principle of surgical asepsis - is to ensure maintenance of asepsis- A sterile object remains sterile only when touched by another
sterile object- Only sterile objects may be placed on the sterile field- Sterile objects or field should be kept in view
Additional precaution - dedicated patient equipment- Allocation of private room with an ensuite for the patient- Use of particular filter mask e.g for patients with tb- Use of PPE- Use of Signage e.g. Stop infection control
WOUND - A wound is a disruption of normal anatomical structure &function that results from pathological process beginninginternally or externally to the involved organs. (Harvey, 2005)
Wound classificationSTATUS OF SKIN INTEGRITY
Open - wound involving a break in skin or mucous membranesClosed - wound involving no breaks in skin e.g. part of body being
struck by blunt object e.g. straining or deceleration offorce against body.
Acute -wounds that proceeds through an orderly and timelyreparative process that results in sustainedrestoration of anatomical and functional integrity.
Chronic - wound that fails to proceeds through an orderly andtimely process to produce anatomical and functionalintegrity.CAUSE
Intentional - wound resulting from surgery - surgical incision;
-

400749 - NURSING & HEALTH BREAKDOWN SPRING REVISION
introduction of needle into body partUnintentional - wound that occurs unexpectedly - traumatic injury;
knife wound, burnSEVERITY OF INJURY
Superficial - wound that involves only epidermal layer of skin
Penetrating - wound involving break in epidermal skin layer, aswell as dermis and deeper tissues or organsPerforating - Penetrating wound in which foreign object enters and
exits an internal organCLEANLINESS
Clean - wound containing no pathogenic organismsClean contaminated - wound made under aseptic conditions but
involving body cavity that normally harboursmicroorganisms. e.g. surgical wounds enteringgastrointestinal, respiratory, genital or urinary tract.
Contaminated - wound existing under conditions in which
presence of microorganisms is likely e.g. open,traumatic, accidental wounds; surgical woundsin which break in asepsis occurred.
Infected - Bacterial organisms present in wound siteColonised - wound containing microorganisms (usually multiple)
DESCRIPTIVE QUALITIESLaceration - tearing of tissue with irregular wound edgesAbrasion - superficial wound involving scraping or rubbing of skins
surface e.g. wound often resulting from fall (skinnedknee or elbow)
Contusion - closed wound caused by blow to body by blunt object:
contusion or bruise characterized by swelling discolorationand pain e.g. bleeding in underlying tissue caused by bluntforce against body part
Inflammatory response - sequential reaction to cell injury. It neutralizesand dilutes the inflammatory agent, removes necrotic materialsand establishes an environment suitable for healing andrepairType of Wound - Clean
Clean contaminatedContaminated
Infected
Wound Assessment - Observed the wound forWound apperance - consistency and amount of drainageApperance of surrounding skinOedemaBleedingColour - serous, purulent, haemoserous (serosanguineous),
sanguineousApproximation of suture line

400749 - NURSING & HEALTH BREAKDOWN SPRING REVISION
Drains/DrainageWound Asessment - Colour, consistency and amount of drainage
Colour can be: Sereous/ Purulent/ Haemoserous/SanguineousType of dressing
Woven gauze sponges - it is absorbent and are especially useful inwounds to draw away the wound exudates.Wet to dry dressing - use in treating wounds that require
debridement.None adherent gauze dressing - such as Telfa are used over
clean wounds. Telfa gauze has a shiny, non-adherentsurface that does not stick to incisions or wound openingsbut allows drainage to pass through to the softenedgauze above.
Self- adhesive, transparent film - acts as a temporary second skinsuch as Opsite, blisterfilm etc.
Purpose of dressing- protect a wound from microorganisms- Aiding haemostasis- promoting wound healing- supporting or splinting wound site- protecting the patient from seing the wound- promoting thermal insulation of the wound surface- providing maintenance of high humidity between the wound and
the dressing

oral.
4 Routes for parenteral routes- Subcutaneous (SC) - injection into tissue below the dermis of
the skin eg. insulin, heparin
Intramuscular (IM/IMI) - injection into a muscle eg. pain relief,v vaccination *most effective administration*Intravenous (IV/IVI) - injection into a veinIntradermal (ID) - injection into the dermis immediately below
the epidermis *less effective*
Intramuscular injection sites- Bum Cheeks (Ventrogluteal) - 4mls- Arm (Deltoid) - no more than 2 mls- Thigh (Vastus lateralus)- can inject up to 5 mls
Advantages can be gicven regardless of consciousness of patient,
more rapeidly absorbDisadvantage- localized redness, painful, nerve damage, bleeding, skinirritation, oential nerve damages
Oral routes- SUBLINGUAL administration (SL) - placed under the tongue
todissolved e.g. Glyceryl trinitrate
- Should not be swallowed, as desired effect will notbe achieved
- Pt would not be allowed to drink until medication iscompletely dissolved
- BUCCAL Administration - placing the solid medication inthe mouth against the mucous membranes of the cheeks whereit stays until it dissolves
- Can alternate checks to avoid mucosal irritation- Pt is not allowed to chew or swallow medication or to
take with any liquids- Acts locally on the mucosa or systemically as it is
swallowed in a persons saliva

WEEK 6 - PRINCIPLES FLUID & ELECTROLYTE MANAGEMENT
Maintain health and function of all body systemA balance (homeostasis) is maintain by
1. Intake and output of H20 and electrolytes2. Hormonal regulation (ADH, aldosterone, renin and angiotensin I)
Daily Fluid Intake and OutputAv. Adult = 2200-2700mls a dayUrine output Formula: 0.5ml - 1ml/kg/hr
Nursing assessment of FVD- Monitor, assess and document accurate intake and output
(FBC)- Assess and document urine output (colour, quantity,
concentration, urine specific gravity -the higher it is themore a pt is dehydrated)
- Monitor and document fluid loss form wound drainage,tubes, diarrhoea, bleeding, vomiting
- Monitor lab results (blood, haematocrit and BUN)- CVP monitoring (low CVP)- Colour , smell
- Glasgow coma scale (15) 12 is serious- Daily weight
Electrolyte imbalances- Hypokalemia - a low potassium level in the blood. This is
likely to be present in dehydration and with theprolonged use of certain diuretics.
- Serum K3.5mEq/L- Signs: Dyshythmias, ECG changes, N&V, anorexia,bowel sounds, ileus, muscle weakness, leg cramps
- Hyperkalema- Serum K5mEq/L- Signs: tall peaked T waves, widened QRS, dysrhythmias,
cardia arrest; N&V, abdominal cramping, diarrhoea;muscle weakness, paresthesias, flaccid paralysis

FLUID BALANCE EXCESS
- CAUSE BY FLUID OVERLOAD- RESULT WHEN BOTH WATER AND SODUIM ARE RETAINED IN
THE BODY
SIGNs & SYPTOMS
- WEIGHT GAIN- PERIPHERAL OR severe generalized oedema (anasaca)- Full bounding pulse, tachycardia, increase BP- Distended jugular neck vein (icrs. JVP)- SOB (short of breath) etc.
NURSING MANAGEMENT
- Monitor intake and output monitor for physical signs and symptoms of
hypervolemia- weight
- monitor side effects
ELECTROLYTE IMBALANCES
HypokalemiaSerum K5mEq/L
Signs:Tall peaked T waves, widened QRS, dysrhythmias, cardiac arrest; N&V, abdominal
cramping, diarrhoea; muscle weakness, paresthesias, flaccid paralysis
- Loss is not confined to the experience of losing someone through death- Loss is a phenomenon which occurs across the lifespan and is an inevitable part of the
transitions, changes and growth that occur through everyday life- Loss derives meaning from the person experiencing it
Key points- Assess- Monitor- Document
Factors that require assessments-Skin turgor-Mucous membranes

- A disease or injury that dev/elops during the treatment of a pre-existing disorder..The
complication often alters the prognosis
- An accident or second disease process arising during the course of or following theprimary condition; can be fataL
- We define the term complication to be a universal term, encompassing both events related
to the disease process and events related to healthcare interventions
Risk factors
- Age
- Nutrition- Obesity- Radiotherapy- Fluid & electrolyte balance- Pregnancy- Medical conditions- Drugs

WEEK 8 - PRINCIPLE OF PAIN MANAGEMENT
- An unpleasant sensory & emotional experience associated with actual or potential tissue
damage, or described in terms of such damage (International Association for the Study of Pain, 2008)
- Pain is whatever the experiencing person says it is, existing when he says it does(McCaffery, 1979)
- Pain is subjective and highly individual (Crisp & Taylor 2009).
Pain perception (pathphysiology)
- The point at which a person is aware of pain- Depends on the functioning of higher brain centres,
therefore, only exists if it is interpreted by the CNS
- Perception gives awareness to pain, after whichPhysiological & behavioural responses follow (signs
& symptoms- Described in terms of pain threshold and pain tolerance.
Pain threshold - refers to the point at which pain is first experienced
- little variation between individuals in terms of pain threshold
Pain tolerance - the point at which an individual reports pain to be so intense that itcan no longer be tolerated
- wide variation in the tolerance, associated with the age, gender,
ethnicity, past experience & other factors.

400749 - NURSING & HEALTH BREAKDOWN SPRING REVISION
Physiological
- Autonomic nervous system stimulated as part the stress response- Flight or fight response- continues
Behavioural Responses to pain
- Vocalisations- Body movements- Facial expressions
Classification of painAcute - short term usually nociceptor
Chronic - long term long lasting pain
Pain managent
- Prevalence of unrelieved pain in hospitalized (inc post-operative)- Studies show similar problems for pt across various care setting
Pain assessment
- Accurate assessment is vital- Many factors can potentially influence the pain experience incl. staff attitudesor action.
- Self report is the indicator of pain severity
ABCDE approach
- Ask about pain regularly - Assess pain regularly- Believe the pt & family in their report of pain and what relieves it- Choose pain control options appropriate for the pt, family setting- Deliver interventions in a timely, logical and coordinated fashion- Empower pt and their family - Enable them to control their course to the
greatest extent possible
PAIN RATING SCALES- measures pain intensity
- Verbal rating scale (VRSs)- category scales consisting of various words e.g. mild or severe
- visual analogie scale (VAS)
-A 10cm line anchored at each end with the words such as no painand the worst pain possible
Pain rating scales - 1 from no pain to 10 worst pain imaginable
Observational charts - recording of behaviours which accompany pain
- medication use- level of function
- non verbal expression - body /face languagePain in children - Assessment of pain in children incl. hx, physical examination,physiological and behavioural measurement and commonly the pain facesscale.
Pain management pharmacological approaches
- Opoids none steroid and anti-inflammatory drugs- Paracetamol -- Local anesthetics

- Cognitive - behavioural approaches- Acupunctures- Mobilization- arotheraphy
Physical approachesSpinal manual therapy
Mobilization
Application of superficial hear or coldExercise
Trancutaneous electrical nerve stimulation (TENS)
FACTORS WHICH INFLUENCE INDIVIDUALS EXPERIENCE OF PAIN
Physiological consciousness, neurological function , age, gender,
Social social dependant, support network and stressors.Spiritual -/cultural different language, meaning and attitude associated with pain across
various cultural group, meaning of pain belief in high power
Psychological arousal of the non adrenegenic brain. Attention previus expercinceanxiety and coping style

None adherent gauze dressing - such as Telfa are used over cleanwounds. Telfa gauze has a shiny, non-adherent surfacethat does not stick to incisions or wound openings but allowsdrainage to pass through to the softened gauze above.
Self- adhesive, transparent film - acts as a temporary second skin
such as Opsite, blisterfilm etc.Purpose of dressing
- protect a wound from microorganisms- Aiding haemostasis- promoting wound healing- supporting or splinting wound site- protecting the patient from seing the wound- promoting thermal insulation of the wound surface- providing maintenance of high humidity between the wound and
the dressingColour
- Red - blood is getting their - healing- Yellow - infected- Black - necrotic
Wound healing
Primary intention- Wounds where margins are neatly approximated
- Healing occurs in 3 phases

1. Initial phase (3 - 5 days)
2. Granulation phase (5 days - 4 weeks)
3. Maturation phase & scar contracture (7 days - several months)Secondary Intention
- Healing of wounds with edges that cannot be approximated
- Healing same as in primary but the inflammatory reaction may be greater- Healing takes place from edges of wound inward & bottom of wound upTertiary intention
- Healing occurs with delayed suturing of the wound- Occurs when:
- Contaminated wound left open & closed once clean- When primary wound infected, is opened, allowed to
granulate then sutured
Conditions for wound healing
- Well being- Nutrition
- Vascular supple/drainage- Clean wound- Minimal trauma- Moist environment- Thermal regulation
Factors that promote wound healing
- Maintain strict asepsis during surgery and the post operative period is thesingle most important factors in promoting wound healing
Factors delayed wound healing
- obesity- debilitation (weakness & mobility)
- advanced age- mechanical friction on the wound- Treatments - steroids, chemotherapy, radiotherapy- Nutritional deficiencies- Presence of disease e.g. diabetes mellitus- Presence of infection- Inadequate blood supply- Poor general health- Impaired oxygenation / Anaemia- Smoking- Wound stress
Signs & Symptoms of impaired wound healingWound infections often evident within 36-48 hrs post op. most appear
within 5 - 7 days
Signs & Symptoms of INFECTION- Increased temperature (swinging heat around wound)- Increase heat around wound- Increase or change in exudates- Increased discomfort

- General malaise (feeling of a general discomfort illness)Classification Pressure ulcers
Stage I - Intact skin with non blanchable rednessStage II - partial thickness skin loss involving epidermis/ dermis on both
Stage III - full thickness tissue loss with visible fat
Stage IV - full thickness tissue loss with expose bone and muscleStage V un stagable or necroticPredicting & preventing pressure ulcers
Risk assessment:
- Hygiene and skin care- Positioning- Support services

Factors affecting pressure ulcer healing- Shearing- Friction- Moist- Nutritional status- Anemia- Cachecxia (a condition of extreme debility)- Obesity- Infection- Impaired peripheral circulation- Age
Nursing process assessment- Predictive measures- Skin- Mobility- Nutritional status- Pain- Patient expectations- Wound appearance- Character of wound drainage- Drains- Wound closure
- Palpation of wound- Wound cultures- Observe the wound for - Appearance of the wound and surrounded skin

- monitor drains
- Colour, consistency and amount of drainage
- Colour can be:- Serous- cleae watewry plasma
- Purulent think, yello gren and brown
- Haemoserous (serosanguineous) pale, red watery and mixed obboth serosanguinoues and sangeinous
-Sanguineous bright red , indicated heavy bleeding
- Assess the wound for signs of infection- Inflammation
- Drainage (increased ooze from wound)
- Odour
- Pain- Induration (hardened tissue)
- Take a wound hx by asking - cause
- when
- what was the initial size- what were the changes
Nursing Process intervention
- Nursing intervention to promote improved skin integrity and / or woundheaing
- Consult health professionals such as nutritionist and wound carespecialist
- Involve the pt and family in using interventions- Dressing- Purposes of dressing- Types of changes
- Changing dressings- Packing a wound- Securing dressing- Pain management- Clean skin and drain sites- Suture care- Drainage evacuation- Bandages- Planning education- Further of wound care- Signs and symptoms of manifestation of infection
