Background: Magnetic resonance imaging (MRI) has become one of the most essential diagnostic medical imaging techniques. The most common disadvantage of MRI is that patients may feel anxious before the examination, which can negatively affect them, prevent them from attending or completing the examinations, and cause patient movement during the examination, which accordingly results in misinterpretation issues. Recently, several methods have been suggested to reduce MRI anxiety. Our study aimed to examine nurses' roles in reducing the levels of patient anxiety during pre-MRI scans by using informative video. Methods: A cross-sectional and interventional study was conducted among MRI patients in Tabuk City. A convenience sample of 16 patients as the case group and 28 patients as the control group was included. A 2-minute informative video clip containing comprehensive instructions about MRI was recorded by the research team in the MRI room and introduced to patients 30 minutes before the scan in the waiting area. An Arabic version questionnaire (State-Trait Anxiety Inventory) was used to measure the pre-MRI-related anxiety of patients in the case and control groups. State-trait anxiety scores were analyzed and compared between groups. Median pulse, oxygen saturation, and blood pressure were also compared between the cases and control groups using a p-value of 0.05. Results:The state anxiety score was significantly higher in cases compared to controls. However, the trait anxiety score was not significantly different between cases and controls. Females showed significantly higher state anxiety scores in the cases than in the controls. Based on the previous MRI experience, the cases group who had undergone a previous MRI had significantly higher state anxiety scores than those in the control group. Based on the educational degree, cases with bachelor's degree had higher state anxiety scores than their counterparts in the control group. Conclusion:The present study showed that the self-made visual tool used by nurses 30 minutes before MRI scan did not reduce the level of anxiety significantly in patients. However, state anxiety scores increased in females, patients with previous MRI experience, and patients with a higher educational degree. Healthcare professionals may need to consider the negative effect of informative video before MRI.

Objective: to assess nurses’ knowledge and practice toward computed tomography scan safety guidelines. Methods: a cross-sectional study was conducted using a convenience sample of 131 nurses from two government hospitals. Self-designed questionnaire was used to assess nurses’ sociodemographic characteristics, knowledge, and practice. Descriptive analysis was performed to evaluate characteristics, correlations were evaluated using Spearman’s rank correlation coefficient, and the Mann-Whitney U and the Kruskal-Wallis H tests were used to compare the mean ranks of knowledge and practice scores. Results: most respondents were female (91.6%), were aged 20–29 years (57.3%), and had bachelor’s degrees (74%). Knowledge and practice levels were 58% and 78.9% respectively. A positive correlation between knowledge and practice was observed among nurses (r=0.684, p<0.001). No statistically significant differences were observed between sociodemographic characteristics and knowledge and practice scores. Conclusion: nurses showed adequate level of practice toward computed tomography scan safety preparations while their knowledge level was deficient. Contributions to practice: this study informs the importance of knowledge in guiding nursing practice toward appropriate computed tomography scan safety measures.
