When conducting research, it is important to evaluate all of the sources you encounter. The CRAAP Test, which was originally developed by the University of California's Chico Meriam Library, can help you sift through all the information you uncover to determine what sources are reliable.
Currency relates to the timeliness of the information. Consider the following questions:
Some information will be timeless, meaning that the age of it doesn't affect its usefulness. Historical or theoretical information, for example, could still be useful whether it was published yesterday or more than five years ago.
Other information seems to change on a daily basis, especially in the fields of medicine and technology. You don't need a decades-old diagram on how to perform a specific medical procedure, unless you're looking at the evolution of medical practices over time. You want the most up-to-date information available to inform your nursing practice.
It's not always possible to figure out when something was published, so look for copyright statements, or use other context clues to help you determine the publication date. If the resource cites other items, look at their publication dates. If it doesn't cite anything past 2010, then it was probably published in 2011 or 2012.

Reliability relates to the trustworthiness of the information. Consider the following questions:
Just as you're expected to cite information whenever you write a paper, any author making claims in the resources that you're using should do the same. If they provide information, especially statistics, without giving proper credit to the original source--or without detailing their research methodology--then how can you trust that the data is reliable?
If there aren't any citations or references in the resource, why is that? Do the authors expect that the majority of their readers already agree with the claims that they're making, or are they making claims based solely on their own personal biases or opinions, which might not be supported by any real evidence?
Make sure that you can tell the difference between fact and opinion. Don't blindly trust everything that you read/see. Try to verify all information that you come across, especially if you plan to use it in your own writing.
Relevancy relates to the importance and usefulness of the information to your specific research needs. Consider the following questions:
Consider the course that you're taking and the paper that you're writing. Would a juvenile reference source give you the detailed information that you need to write your senior capstone or graduate-level research paper? What about a magazine article that's meant for everyday easy reading and doesn't require any special knowledge to understand? Neither of those resources would provide the information that you'd need to write a research paper.
Focus your research on resources written by academics and professionals in your field. These types of resources tend to be more authoritative than something that's been written for the general population.

Authority relates to the source of the information, particularly the credentials or education-level of the people who created the resource and whether or not they have the knowledge or expertise required to produce it. Consider the following questions:
Everyone has an agenda, and everyone has a reputation. Make sure that the authors and publishers of your sources are in good standing within their field of study and are truly focused on educating students, professionals, and fellow researchers with verifiable facts.
Accuracy relates to the truthfulness or correctness of the information. Consider the following questions:
You should always be able to trace secondary information back to its original source. If possible, try to get your hands on the original source of information.

Abstract. A brief summary of the key points of the scientific paper.
Methods. Detailed information on how the study was performed.
Results. What the study showed. This section doesn’t attempt to evaluate the meaning of the results. It just presents the data, summaries, and analyses of the data collected from the study. Also, this section often includes tables, graphs, and charts that show the results.
Discussion and Conclusion. What the results mean. This is where you can often find out how the study relates to your own health. This section often includes the authors’ explanation of, and own opinions about, what the results mean. Since the conclusions are the authors’ own, others may or may not completely agree with their explanations of the results.
References. Previously published articles the authors used to review what related research was done before, to help design the study and interpret its results.
