If you use AI Tools, like ChatGPT, in your paper or presentation, describe how you used the tool. For example, which tool did you use, which version, what did you ask the tool to do. In your text, provide the prompt you gave the AI tool and and then the generated response.
Unfortunately, the results you get will not be retrievable by others. This type of material is usually cited as personal communication, however there is no other person communicating so quoting from ChatGPT's text session is more like sharing an algorithm's output. In this case, you credit the author of the algorithm with a reference list entry and an in-text citation.

If the image is from a book/book chapter or journal article, and was created by the authors of that source, just cite the book/chapter or article. If you are using the image in your work cite it as you would a direct quote, and include a page number.
Note: Although for most images you must look at the license on a case-by-case basis, images and clip art from programs such as Microsoft Word and Microsoft PowerPoint can be used without attribution. By purchasing the program, you have purchased a license to use the clip art and images that come with the program without attribution.
For clipart or stock images found online:
To use the image as a figure in an APA Style paper, provide a figure number and title and then the image. Below the image, provide a copyright attribution in the figure note. In a presentation, the figure number and title are optional but the note containing the copyright attribution is required. The copyright attribution is used instead of an in-text citation. The copyright attribution consists of the same elements as the reference list entry, but in a different order (title, author, date, site name, URL).

Notes for citing videos:
If you have more than one director use (Directors) instead and separate their names with commas, adding an ampersand (&) before the final name. If the director is unknown, credit someone in a similar role (producer/writer) and put their job title in round brackets after their name. You can often find all the information you need on the Internet Movie Database website.
For in-text citations, because videos do not have page numbers, provide a time stamp for the beginning of the scene you are citing.

In APA, in-text citations are inserted in the text or body of your document to briefly cite the source of your information. Brief in-text citations point the reader to the full information in the Reference list at the end of your document.
When using APA format, follow the author-date method of in-text citation. For this method include the author and date within the body of your document and include a corresponding reference in the list at the end of the document. This method allows the reader to identify sources used in your document, then easily locate them in the alphabetical reference list.
Create an in-text citation whenever you quote another work or paraphrase another work in your own words.
If you are referring to the idea in another work (paraphrasing or summarizing) but NOT directly quoting it, you do not need to include the page numbers in your in-text reference.
If you are directly quoting - using the exact same words- from another work, you should include the page numbers at the end of the parenthetical citation. For example, (Simerlein, 2023, p. 47).
There are two ways to integrate sources into your assignment:
Readers should be able to move from your own words to the words of your references without feeling an abrupt shift. Signal phrases provide clear indicators to prepare the reader for the quotation/paraphrase. In APA verbs are typically used in the past tense when introducing a quote or paraphrased section. Choose verbs that reflect the author's intent. Some common signal phrases are:
Author Type |
Parenthetical Citation |
Narrative Citation |
---|---|---|
One Author | (Corso, 2013) | Corso (2013) |
Two Authors | (Aros & Nooraldeen, 2014) | Aros and Nooraldeen (2014) |

If a quotation is 40 or fewer words, treat it as a short quotation:
Note: If page numbers are not available (e.g., webpages, some e-books, etc), provide readers with another way of locating the quoted material. You can use a heading or section name, a paragraph number (count them manually), or a combination of both.

Researchers have studied how stress affects nursing students: Nursing students often face significant stress due to the demanding nature of their coursework, clinical rotations, and high-stakes examinations, which can lead to feelings of burnout and decreased academic performance if not properly managed. To manage stress during nursing school prioritize self care, practice effective time management strategies, build a support network of peers and mentors, and don't be afraid to ask questions.
