Dr. Watson is interested in health care for children whose families are homeless. She decides to investigate how parents who are homeless go about finding health care for their children including well-child care as well as emergency care. She decides to interview homeless parents beginning with the question, "Can you tell me how you find health care for your children?" After data analysis, she develops a theory based on the data that describes how homeless families find pediatric healthcare. The best way for Dr. Watson to find literature for her literature review is by:
A) copying the review of literature from a similar article that has been published in the journal she plans to submit her article to.
B) using the nursing data bases and key words
C) using the reference lists from articles she already has on hand
D) going through nursing journals, looking for articles on the topic
