The theoretical framework you select for your DNP scholarly project sets the backbone, tone, and process for your project, but you cannot usually simply search the literature for 'nursing frameworks' to select one. The framework you select should be based on how well it will work for your project - does it aid in assessing what you want it to? is it easy to implement? does it work within your timeframe? To find one, return to any course readings that discussed potential frameworks. Also look at studies that are similar to your own for the researcher's process. Searching for frameworks be field and type of research. Below are a few links to spark your thinking, but by no means an exhaustive list of options.
This USC guide outlines the purpose of a theoretical framework for your research, and how to go about selecting one.
This guide from SUNY Buffalo lists some commonly used frameworks.
