M.Cur. (General Intensive Nursing) / In South Africa, where the nurse is seen as an independent practitioner, she must take continuously accountability and responsibility for her actions. Only she can decide whether she is legally able, or knowledgeable and competent enough to accept a prescription or direction from a doctor. Once she has indicated acceptance, she has made an independent decision and accepts full responsibility and accountability for her decisions and actions. Accountability means that the nurse must be able to give a reason for her actions and or omissions. It is very important that she has enough knowledge of the effects, side-effects, indications and contra-indications of the medications that are prescribed by the doctor before she administers it. Knowledge of medications and the Nursing Act with related regulations that directs her practice, are very important to the nurse to ensure a high standard of nursing care. The nurse working in an intensive care unit must often make decisions in a crisis situation in connection with her legal accountability. So much more in the private sector where the intensive care nurse must .often rely on her own judgement and knowledge because a doctor is not always available. Two questions evolving from this is what is the nurse's responsibility with in the legal framework of medication administration in a intensive care unit and do nurses have enough knowledge of selected medications? These two questions have been answered by evaluation of the doctor's prescriptions and nursing actions, with the help of prelisted control lists and a questionnaire The results of the study showed that the doctor's prescriptions were not legally correct and nurse's actions and knowledge of the selected medications were not up to the expected standard in the chosen unit. Two recommendations evolving from this study are that inservice training to increase knowledge of medications that are frequently used in the unit should be presented monthly and that more time must be spent on pharmacology during the training of the intensive care nurse.

The purpose of the research was to describe the relationships between social support and role strain and preventative health behaviors. The sample consisted of 62 critical care nurses employed in three southwest acute care facilities. Subjects completed instruments measuring social support, role strain, and four preventative health care behaviors. Pearson correlations revealed significant positive relationships between social support and personal/household roles women perform and ways women handle stress. Additional significant negative relationships existed between marital/relationship roles women perform and leisure physical activities, a subset of preventative health behaviors. The parental roles, obligations, and responsibilities women perform were also significantly related with leisure physical activities. Conclusions drawn indicate that the critical care nurses did not perceive themselves susceptible to cardiovascular disease and therefore did not participate in preventative health care activities, regardless of perceived helpful social support and an absence of role strain.

M.Cur. (Intensive Care Nursing) / The problem of intensive care nurses leaving the profession due to non-conducive working environments and uncompetitive conditions of employment is becoming more alarming and is therefore as relevant as ever. The researcher is concerned about the quality of nurse-awareness nurses create in order to practice quality nurse care. Confusion among nurses about their professional rights and responsibilities adds fuel to the fire. The management of health care services is at times not sensitive to the needs of nurses, and nurses are not always recognized for their inherent professional worth. In the adult intensive care unit at which the researcher practices as unit manager she perceived her colleagues to be experiencing some sort of emotional and spiritual discomfort in going about their daily activities. As the researcher felt responsible for the well-being of the staff in the unit she decided to investigate the phenomenon via a formal research study. The objectives of the study were two-fold: Firstly to explore and describe the registered nurse's experience of nursing in the intensive care unit and then to use the information obtained to describe guidelines for the compilation of a support programme for the nurses nursing in the unit The research questions that were generated are: How do registered nurses in the intensive care unit experience nursing there and how can the information be utilized to describe guidelines to support these nurses? The researcher used an exploratory, descriptive, contextual and phenomenological qualitative design to answer these research questions. Phenomenological interviews were conducted with five interviewees who had been possessively selected.

M.Cur. / The nursing service manager is accountable for the managerial outputs of the nursing service, being quality nursing care, cost effectiveness and quality nursing staff management. These managerial responsibilities will influence the overall management efficiency of the health delivery system. There is a need for a more scientific basis of staffing in South African critical care units. Various methods are used to determine staffing needs, but the most accurate and acceptable method being used is the patient classification system. The success of a critical care patient classification system is based upon the accurate determination of the ideal nurse-patient ratio. Ideal nursepatient ratio depends on matching the competency of the critical care nurse to the severity of the critical care patient's illness. Internationally and nationally very few guidelines describe the competency requirements that the critical care nurse should have to function effectively in the critical care unit. To maintain a high standard of quality nursing care, the critical care nurse should be assigned to a critical care patient according to her competency level. The aim of this study was to describe a scientific patient classification system for critical care patients according to which workload and nursing requirements can be ascertained. Secondly, to describe guidelines for the competency requirements of a registered critical care nurse assigned to nurse the different categories of critical care patients categorised by the patient classification system as prescribed. The aim of the study is justified by means of an exploratory, descriptive, contextual research design. A critical care patient classification system has been developed and validated by a group of critical care nursing experts using a structured two phase research method. The statistical validity of each item of the critical care patient classification system was determined by means of a content validity index. All the items of the critical care patient classification system were rated as valid and therefore the critical care patient classification system as a whole has been accepted as valid. The reliability of the critical care patient classification system was tested by means of a pilot study in two selected research units. It was determined that the inter-rater reliability was within the 95 per cent confidence interval, that the system could discriminate between different critical care patients and nurse-patient ratios were effectively determined by the system. Critical care nurse competency requirements were identified by critical care nursing experts by means of a focus group interview. The results obtained from the focus group interview were verified by a literature control and peer group review. Guidelines for the competency requirements of the critical care nurse were compiled. The critical care patient classification system developed will equip the critical care manager with a scientific instrument to assign personnel to critical care units. The critical care patient classification system will furthermore assist the critical care unit manager in the daily utilisation of valuable human resources, in that critical care nurses with the appropriate level of expertise can be assigned to each patient, thus facilitating quality critical care nursing.

The tenn Acute Coronary Syndrome (ACS) encompasses a spectrum of patients who present with chest discomfort or other symptoms caused by myocardial ischemia or infarction. Since critical or acute care nurses care for such patients, they should have a thorough knowledge of ACS pathophysiology and current treatments for ACS The purpose of this research study is to explore and describe the knowledge level that the critical care nurses in a state hospital in East Texas feel they have regarding ACS. This study was quantitative, descriptive and contextual in design, in which a sample survey was performed, using a questionnaire based on a literature study. The response of most ofthe critical care nurses tested was that they felt they had insufficient knowledge. An in-service training session has been proposed to help improve the nurses' knowledge and expertise on ACS. / Health Studies / M.A. (Nursing Science)

Thesis (MCurr)--Stellenbosch University, 2012. / ENGLISH ABSTRACT: The increasingly complex role of the critical care nurse in an intensive care environment demands a much higher level of critical thinking and clinical judgment skill than ever before. Critical thinking in nursing practice may be defined as the cognitive ability to analyse, predict and transform knowledge, ensuring quality nursing care. To reason from a nurse’s perspective requires that we learn the content of nursing; this includes the concepts, ideas and theories of nursing. The aim and objectives of the study were to explore critical care nurses’ perspectives and experiences with regards to the concept of critical thinking, facets influencing the application of critical thinking skills in clinical practice and how these impact on the delivery of quality nursing care. A qualitative approach, using a case study design was utilised. A sample of six participants, who met the study inclusion criteria and consented to participate, were interviewed individually. Subsequently, five of these six participants took part in a focus group discussion to capture additional data to clarify and enrich the individual interview data. A field worker was present during the interviewing processes to note non-verbal data and later verify transcribed data. Feasibility of the proposed study was established by conducting a pretest which elicited relevant information. Ethical approval for the study was obtained from the Health Research Ethics Committee at the Faculty of Medicine and Health Sciences, Stellenbosch University. Permission and consent was obtained from the relevant hospital group to interview nurses working in the intensive care units. Qualitative content analysis, which focuses on the content or contextual meaning, was used to analyse interview data. Coding of the data through emergent themes and sub-themes was done by the researcher and supported through independent coding to verify and strengthen the analysis and interpretation of the researcher. . The results depicted how the participants personally understood the concept of critical thinking and the components influencing the application of critical thinking skill in clinical practice. The study of the participants’ perspective of the concept of critical thinking and portrayed how they experience analytical and independent thinking, competence and confidence, as well as knowledge, skill and expertise, to influence the quality of patient care. The data revealed several themes that facilitated critical thinking in critical care nurses. These themes were ‘team support’, ‘experience and exposure’ and ‘empowering the mind’. Emergent themes elaborating the limitations of critical thinking included ‘being stressed’, ‘professional boundaries’ and ‘being busy’. Several recommendations and suggestions for future research were offered. / AFRIKAANSE OPSOMMING: Die toenemende komplekse rol van die kritieke-sorgverpleegster in ’n intensiewe-sorg omgewing verg ’n veel hoër vlak van kritiese denke en ’n kliniese oordeelvaardigheid as ooit tevore. Kritiese denke in ’n verplegingspraktyk kan gedefinieer word as die kognitiewe vermoë om te kan analiseer, om vooruit situasies te kan bepaal en die vermoë om kennis te omskep sodat kwaliteit verpleegsorg verseker kan word. Om soos ’n verpleegster te kan dink, stipuleer dat die inhoud van verpleging geleer moet word wat konsepte, idees en teorieë daarvan insluit. Die doel en oogmerke van die studie is om die ervarings en perspektiewe van kritieke-sorgverpleegsters te ondersoek, met betrekking tot die konsep van kritiese denke, fasette wat die toepassing van kritiese denkvaardighede in ’n kliniese praktyk beïnvloed en die impak daarvan op die lewering van kwaliteit verpleegsorg. Die metodologie wat toegepas is, is ’n kwalitatiewe benadering deur middel van ’n gevalle-studie ontwerp. ’n Steekproefgrootte van ses deelnemers wat aan die inklusiewe kriteria voldoen het, is mee onderhoude individueel gevoer en daarna is met vyf van hierdie ses deelnemers in ’n fokusgroep onderhoude gevoer ten einde data op te neem wat andersins verlore kon geraak het. ’n Veldwerker was teenwoordig gedurende die proses van onderhoudvoering om die opgeneemde en getranskribeerde data te verifieer. Die data-insamelingsinstrument is in die vorm van ’n onderhoudsgids ontwikkel om die navorser gedurende die onderhoudvoering te help. ’n Loodsondersoek is uitgevoer om die haalbaarheid van die voorgestelde studie te ondersoek en is sodoende geskep om relevante inligting te onthul. Etiese goedkeuring vir die studie is verkry van die Gesondheidsnavorsing Etiese Komitee aan die Fakulteit van Geneeskunde en Gesondheidswetenskappe, Universiteit Stellenbosch. Goedkeuring en toestemming is van die hospitaalgroep aan wie die hospitaal behoort verkry, waar die studie onderneem is om sodoende onderhoude te kan voer met verpleegsters wat in die intensiewe-sorgeenhede werk. ’n Primêre, kwalitatiewe inhouds analise is gebruik om omderhoud data te analiseer wat fokus op die inhoud of kontekstuele betekenis daarvan. Kodering van die data deur die toepassing van die temas en sub-temas wat voorgekom het, is deur die navorser gedoen. Die data is onafhanklik gekodeer om die analise en interpretasie van die navorser te verifieer en te bekragtig ten einde die akkuraatheid en getrouheid in die formulering van die betekenis en interpretasie van gebeure met juiste weergawe daarvan, te verseker. Die resultate wat as hooftemas vanuit die individuele onderhoude voortgespruit het, asook die van die fokusgroep het die deelnemers se eie begrip van die konsep van kritiese denke en komponente wat die toepassing van kritiese denkvaardigheid in ’n kliniese praktyk beïnvloed, getoon. Die konsep van kritiese denke het die wyse waarop analitiese en onafhankilke denke, bevoegdheid en selfvertroue, asook kennis, vaardigheid en kundigheid die kwaliteit van pasiëntsorg beïnvloed, uitgebeeld. Die voortkomende data het daartoe aanleiding gegee dat die faktore wat die fasilitering en beperking van kritiese denke beïnvloed, bespreek kon word. Data rakende fasilitering het getoon hoedat die ondersteuning van die span, ervaring, blootstelling en die verruiming van die gees, kritieke-sorgverpleegsters positief kan beïnvloed om kritiese denke in hulle daaglikse verplegingsaktiwiteite effektief te kan toepas. Data wat verband hou met beperkings het getoon hoedat stres, professionele kwessies en besigwees kritieke-sorgverpleegsters negatief kan beïnvloed in die toepassing van kritiese denke gedurende daaglikse verplegingsaktiwiteite. Verskeie aanbevelings vir toekomstige navorsing is voorgestel.
