Methods: According to certain screening criteria, 100 outpatient patients in our hospital were included as the research objects, and the screening period ranged from March 2019 to March 2021. The patients were coded by computer and divided into two groups according to the requirement of 1:1 group to implement different nursing modes, namely the control group (routine nursing, n50) and the study group (comprehensive nursing, n50). The puncture success rate was taken as the observation index to analyze the application value of the two nursing modes, compare the quality of blood samples and nursing effect of the two groups, evaluate the nursing risk and summarize the application value of comprehensive nursing. Results: Compared with the puncture success rate of the two groups, the study group had a significant advantage, that is, the success rate was higher (P 0.05). Compared with the standard rate of blood samples in the two groups, the results showed that the study group had more advantages, that is, the standard rate was higher (P 0.05);Comparing the nursing effects of the two groups, the results showed that the study group had obvious advantages in nursing satisfaction and nursing risk incidence compared with the control group (P 0.05). Conclusions: For outpatient blood sampling patients, nursing interventions such as comprehensive nursing have important application value. This nursing model can improve the success rate of blood specimen treatment and puncture, promote nursing satisfaction and improve nursing safety, which is worthy of clinical thinking and reference.展开更多

The era background of internet + has injected new vitality into senior middle school English teaching, and on the basis of the continuous introduction of information technology and related advanced information teaching methods, micro-course resources have gradually been applied in senior middle school English teaching. With its flexible mobile characteristics and diversified innovation advantages, it has brought more possibilities for the high-quality development of senior middle school English teaching. Based on this, this paper discusses and analyzes the application of micro-lesson resources in senior middle school English teaching in detail.展开更多
