Additional help can be found below or at APA Style Help
A DOI (Digitial Object Identifier) is a unique code for an electronic document. The DOI will never change, even even if the URL changes.
Some citation formats require the DOI if there is one.
To look for a document's DOI: crossref.org.
To find a document using the DOI: click on the DOI or go to doi®.
Nursing, education, and many of the sciences use APA citation style.
The final authority for APA is the American Psychological Association, specifically the Publication manual of the American Psychological Association (7th ed., 2020). The final authority for the bibliographic form used in your paper is your professor.

From Publication manual of the American Psychological Association, 7th ed, 2020:
When a work has six or more authors, cite only the surname of the first author followed by et al. and the year for the first and subsequent citations.
List by last names and initials; commas separate author names. After the first 19 authors’ names, use an ellipsis in place of the remaining author names. Then, end with the final author's name (do not place an ampersand before it). There should be no more than twenty names in the citation in total. (e.g. Author, A. A., Author, B., B., Author, C. C., Author, D. D., Author, E. E., Author, F. F., Author, G. G., Author, H. H., Author, I. I., Author, J. J., Author, K. K., Author, L. L., Author, M. M., Author, N. N., Author, O. O., Author, P. O., Author, Q. Q., Author, R. R., Author, S. S., ... Author, T. T.).
