Please, post a short response to the following discussion.

Use a reference from scholarly literature : Peer-reviewed Nursing journal not older than 5 years or your textbook:

 Polit, D. E. & Beck, C. T. (2018). Essentials of nursing research: Appraising evidence for nursing practice(9th. ed.). Philadelphia, PA: Wolters Kluwer. 

Nursing researches, evidence-based practice (EBP), and theories can be subject to reviews and readings. Nursing is an ever-changing science and profession, even though nurses based their knowledge on previous studies. Literature review is significant to the research process because it balances the strength of the knowledge obtained and review the previous information obtained. The nursing research process includes the review or creation of concepts and theories (Polit & Beck, 2018). Therefore, a deep reading and investigation of the research allows for either confirmation, or exclusion, of that research. As Bernhofer (2015) expresses, a thorough review of the literature can show that there is no need to change the practice or, in the other hand, it can show that there is a possibility to improve the outcomes desired by changing the practice protocols. A literature review may influence new researches process and practices as it proves the knowledge already obtained is based on strong and appropriate evidences that were not biased.
