a student query about power/knowledge

A student struggling to write an essay about Foucault writes me as follows:

How is my essay? I am trapped by Foucault's concept of knowledge. This is
because I have
focused on power, and I did not read enough about his argument of
knowledge and discourse. My arguments about the relationship between
power and knowledge is, therefore, quite confusing.

Could anyone offer a few concrete pointers (specific works and page numbers)
to help her? Thank you!
