Application of theory to nursing practice Presentation Transcript

  • 1. Application of theory toNursing PracticePresented byARUN.M
  • 2. • A casual visitor to a hospital or other health caresetting might think that little has changed for nursesover the past decade. The majority of nurses stillwear a traditional and recognizable uniform, and areto be found in areas where care is provided or adviceoffered to patients, their relatives and their friends.However, behind this seemingly unchanged exterior,much has altered. In particular, nurses are noweducated through a different system of training. Theyare educated to a higher academic level, and thework they do and the way in which they do it have, inmany areas of health care, changed considerably.Aggleton P & Chalmers H, 2000
  • 3. IntroductionNursing Science is an identifiable discretebody of knowledge comprising paradigms,frameworks and theories. The integrationof nursing theories into practicedemonstrates an evolutionary pathway forintroducing a paradigm shift in theessence of the science of nursing .
  • 4. • Theories have been developed in nursingto explain phenomena important to clinicalpractice. For eg,we have a theory ofhealth promotion behaviour (Pender &Pender &Pender,1996Pender,1996) and a theory of motherinfant attachment(Walker,1992Walker,1992). Althoughwe use these theories to guide ourpractice, in many cases we have nottested them to determine whether or notthe nursing actions proposed actuallyhave the effects claimed.
  • 5. • The conceptual models and the nursingThe conceptual models and the nursingtheories that provide the basis for clinicaltheories that provide the basis for clinicalpractice arepractice are• Johnson’s Behavioral System Model,Johnson’s Behavioral System Model,• King’s General Systems framework,King’s General Systems framework,• Levine’s Conservation Model,Levine’s Conservation Model,• Neuman’s Systems Model,Neuman’s Systems Model,• Orem’s Self-Care Framework,Orem’s Self-Care Framework,• Rogers’ Science of Unitary Human Beings,Rogers’ Science of Unitary Human Beings,• Roy’s Adaptation Model,Roy’s Adaptation Model,

  • 7. I = integration and synthesis of nursing knowledge through cognitive ,psychomotor and affective domain
  • 8. Nursing in its journey to attainprofessional status incorporatesseveral concurrent changes in thediscipline by• combining research based practice• upgraded educational requirements• theory based models .
  • 9. Why we need to apply nursingtheories ?Using theory helps to guide nursingpractice. It helps to organise data understand and analyse patient data make appropriate decisions related tonursing interventions.
  • 10. Application of Orem’s theory tonursing practice• Orem presents her self –care deficit theoryof nursing which is composed of threeinterrelated theories• Theory of self care• Theory of Self care deficit• Theory of Nursing Systems

  • 13. Assessment PhaseThe nurse collects data in six areas:1. The person’s health status2. The physician’s and nurses perspective of theperson’s health3. The person’s perspective of his health status4. The health goals within the context of life history,lifestyle, and health status5. The person’s requirements for self care6.

Before surgery his baselinevital signs were:heart rate 80 beats per minute;BP120/80mm of Hg and resp rate 16 per minute. After45 minutes in post op recovery his vital signs are:HR 150 beats per minute; BP 90/60mm of Hg; Resprate 32 per minute. { Increased regulator output issignaled by sympahathetic nervous systemstimulation of the heart in response to decreasedblood pressure} The nurse decides that Mr Raj isshowing an ineffective response

  • 31. • Application of Betty Neuman’s Model• Case Study:Janice is a 34-year-old married woman whohas three elementary school-aged children.She moved to the Lower Mainland, fromthe Interior, six months ago because herhusband was transferred by his employer.Janice is currently on medical leave fromher job as a teachers assistant. She wasreferred to an outpatient psychiatric grouptherapy program in order to gainassistance in dealing with depression andanxiety.
  • 32. • Janice states she was feeling "reasonablywell" until February of last year when herhusband informed her of the likelihood ofhis being transferred. She says she haddeveloped many friends in the Interior inthe five years they had lived there, andshe has made few friends since moving tothe Lower Mainland. Janices extendedfamily lives in Ontario, as does herhusbands family.
  • 33. • Janice says they moved to the Lower Mainland last August, twoweeks before school started. The children, aged six, eight andten years, were upset with the move because they were leavingtheir friends behind. Janice feels guilty about this.Another stressor for her is her new job, which she started lastSeptember. She was assigned to work with a child diagnosedwith attention deficit hyperactivity disorder (ADHD). Janice didnot agree with the management style of the teacher whendealing with this child, and she found it difficult to be assertivein dealing with this teacher. Janice says she startedexperiencing anxiety attacks and insomnia in early December.

  • 35. • Janice says that she grew up an only child with an"alcoholic" father and an "anxious" mother. She says shemarried at age twenty years because she couldnt standbeing at home, and she didnt want to live alone.Despite this, she says her marriage is good which shequalifies with, "he doesnt run around or anything. Heworks hard to provide for us, not like his dad who ran offwith another woman".Janices goals for group therapy are to learn ways tohandle her anxiety without medication, and to learn waysto minimize her depression.
  • 36. In applying Neumans model to Janicessituation, the initial assessment is carried out toassess prediposing factors and stressors.• Intrapersonal stressor : depression , insomnia,guilt feeling• Interpersonal stressor: social withdrawal and herlack of her usual supports. Her disturbed sleepleaves her feeling irritable in dealing with herchildren, Conflict with the teacher.• Extrapersonal stressor : Shift to a new place andlack of social support.
  • 37. • In Neumans model, the nursing diagnosisdescribes the whole client situation (Neuman,1995). The nursing diagnosis could be describedas multiple stressors in too short a time framepenetrated Janices normal line of defense,causing an energy drain and a variance fromwellness.• Subsequently, system integrity was notmaintained and Janice developed symptoms ofanxiety, depression and insomnia.• Diagnosis statement : Ineffective coping• : Anxiety• :Sleep pattern disturbance
  • 38. GoalsIn Neumans model, goals are set in collaborationwith the client.• Janice stated her goals were to learn ways tohandle her anxiety without medication and tolearn ways to minimize her chances of becomingdepressed again.{ These are reasonable goals in an outpatientgroup therapy program. These goals arerelevant because they were determined by theclient and were deemed by the nurse to bemanageable goals in this practice setting.}
  • 39. Neumans interventions are carried out at three levels: primary,secondary and tertiary prevention.In Janices situation,In Janices situation, Secondary prevention:Secondary prevention:• assess her sleep pattern.(Janice reveals she takes Prozac at HS.)assess her sleep pattern.(Janice reveals she takes Prozac at HS.)• Advising her to take Prozac in the morning,( as Prozac frequentlyAdvising her to take Prozac in the morning,( as Prozac frequentlycauses insomnia,)causes insomnia,)• Encouraging Janice to talk about ways to handle her anxietyEncouraging Janice to talk about ways to handle her anxietyIITertiary prevention :Tertiary prevention :• exploring anxiety triggers.exploring anxiety triggers.• Her depression would also be explored and she could expect to gainHer depression would also be explored and she could expect to gaininsight about waysinsight about ways• to minimize the occurrence of future depressive episodes.to minimize the occurrence of future depressive episodes.Tertiary prevention focus is to return the person to WellnessTertiary prevention focus is to return the person to Wellness
  • 40. The final stage of Neumans model is nursingoutcomes, or reassessment.• Perceived progress towards her goals and shewould receive feedback from the nurse.• Perhaps she still has insomnia after Prozac ischanged to morning administration. Thisinformation leads the nurse back to assessment.• Changes in intrapersonal, interpersonal andextrapersonal factors would be noted becausechange determines the success of the nursinginterventions.

  • 42. ConclusionWe have seen that these models continueto use the nursing process as the core fordecision making in determining if nursingcare to clients is meeting the expectedoutcomes as established by the clinicalpathways. Applying these theorist views isa challenge and it provides opportunity formeaningful nursing practice
