Background: Critical Thinking (CT) dispositions in nursing are prominent predictors of competence in delivering high-quality care, and of professionalism, in newly graduated nurses. CT skills, in isolation of CT dispositions, do not guarantee success in the workplace, because Critical Thinking Dispositions (CTD) are important elements of intellectual reasoning that simulate a person towards using the CT skills. Therefore, nursing educational programs should promote lifelong learning rather than focusing on transferring the content of nursing knowledge only. And for this purpose, quality education is the key. Education should focus on teaching from diverse perspectives, incorporating various teaching learning strategies that are congruent with the modern era. Purpose: The purpose of this study is to explore critical thinking dispositions among final year Baccalaureate Nursing students of various military colleges of nursing, in Pakistan. Methodology: A descriptive qualitative exploratory study design was used to investigate the CTD of BSc final year nursing students. The study population included twelve willing nursing students, from six military colleges across the country. Demographic information and consent was taken from the participants of the study. In-depth interviews, through a semi structured interview guide, and probes were used to obtain data related to personal experiences of CTD amongst the nursing students. Results: Data analysis showed two broad themes: 1) Perceptions of CT, and 2) Experiences of CT dispositions. In theme one, the emerging category was: Clarity of CT;whereas in theme two, the categories that emerged were: a) Truth Seeking, b) Open Mindedness, c) Inquisitiveness, and d) Self Organization. Conclusion: The findings of the study revealed positive dispositions towards truth seeking, open mindedness, and self-organization, whereas disposition towards inquisitiveness was weak. Self-confidence and maturity also emerged as positive factors that

Introduction: Pakistan has a large number of professional nurses but a higher rate of turnover contributes towards the shortage of nurses which is intensified by nurses’ immigration, lack of recruitment of new nurses and retirement of senior nurses. Aim: The study aimed at examining the factors that increase retention of nurses. Research Method: The study is descriptive cross sectional with a sample of 150 nurses including both the genders, from 3 private hospitals located in Pakistan. A convenient sampling technique was used. The data collection was done through close ended questionnaires based on 20 questions. Data collection was done quantitatively and then data was entered in SPSS. Correlation and regression tests were performed. Findings: The analysis revealed that 91.3% nurses are loyal to their hospitals but, 8.7%nurses can switch the hospital for different reasons. It was also found that the idea of leaving the job based on the intention of moving to abroad and public sector was higher than the retirement and other causes. Resultantly, enhancements in nurses’ work environments have the ability to decrease nurses’ job burnout and turnover and increase patients’ satisfaction. Recommendations: Hospital leaders should implement effective strategies to encourage nurses to continue their job by motivation, strengthening management skills within the hospital and improving a positive work environment by promoting teamwork, continuous learning, trust, respect and flexible arrangements which can lead towards achieving better ***, further studies quantitatively and qualitatively can explore more factors related to dissatisfaction of nurses. Health systems policy makers should lead by developing related strategies for the retention of nurses.
