With nursing basic practical training course as the carrier, the resource base of ideological and political elements is dug up and established, and the comprehensive quality of teachers is improved with the help of various teaching methods. The ideological and political education should be organically integrated into the practical teaching to cultivate high-quality nursing talents in the new era and give full play to the educational function of the basic practical training course of nursing science. This paper discusses the teaching method of integrating ideological and political elements into the nursing basic practical training course and the importance of ideological and political elements in the nursing practical training course.展开更多
