(1) Demographic Data Assessment Questionnaire, (2) Fluid restricted and (3) Diet Restriction Related Questionnaire. Pearson’s correlation (r), T-Test (t) and ANOVA was used for data analysis. Results: The mean score of fluid restriction behavior is 2.04±0.32 and diet restriction behavior is 2.28(±0.41). A significant relationship between fluid restriction behavior with age (p = 0.018) and Nutritional education (p = 0.01). There is also another significant relationship between diet restriction behavior and nutritional education (p = 0.006).
