Objective: To explore the application effect of micro-teaching in the training of intravenous indwelling needle for clinical nursing students. Methods: A total of 102 undergraduate nursing students who were interned in our department from July 2016 to February 2018 were assigned randomly to the experimental group and the control group, 51 for each. The traditional teaching method was used in the control group for the training of intravenous indwelling needle infusion skills, whereas the micro-teaching method was used in the experimental group. Before the end of the internship, the two groups of interns were given a score test of intravenous indwelling needle infusion skills and an anonymous questionnaire survey on teaching effects. Results: The results of the skill test showed that the total scores of the control group and the experimental group were (76.73 ± 1.67) and (84.12 ± 1.90), respectively, and the difference was statistically significant (p < 0.01). According to the questionnaire survey, the percentage of the students in experimental group who had a positive attitude toward teaching methods, interest in learning, self-learning ability, and learning efficiency, was higher than that in the control group, and there was a statistical significance (p < 0.05). Conclusion: Microteaching can effectively promote the nursing students' mastery of intravenous indwelling needle infusion skills, stimulate interest in learning, improve self-learning ability, improve learning efficiency and achieve satisfactory teaching effects.

Objective: To assess and compare the clinical application value of nursing risk management in the diagnosis and treatment of severe peptic ulcer bleeding. Methods: A total of 70 patients with severe peptic ulcer bleeding were selected as the research objects, randomly divided into observation group and control group, 35 cases for each. The nursing risk management and conventional nursing management were implemented for the two groups, respectively. The success rate of hemostasis, average length of stay, cure rate, complication rate, dyspnea rate, nursing dispute rate, SAS score, and SDS score were compared between the two groups. Patients' satisfaction with nursing quality was also compared. Results: After the implementation of two different nursing management methods, all the above-mentioned metrics were better in the observation group than in the control group, and the differences were statistically significant (P < 0.01 or P < 0.05). Conclusion: The application of nursing risk management in the nursing intervention process of patients with severe peptic ulcer bleeding can effectively reduce the probability of nursing risk events, increase the cure rate, shorten the patient's hospital stay, but also improve the patients' psychological state and increase the patient's satisfaction with nursing quality, which is worth clinical promotion.
