Critique and Evidence in Nursing

Words: 565
Topic: Health & Medicine


The literature review provides evidence of techniques used in nursing practice. Additionally, literature review unveils theory on nursing practice. The literature review presents past evidence of a practice problem. Furthermore, the literature review presents available methodologies for nursing practice. In essence, literature presents evidence-based practice on practice problems. It should be noted that credible literature is vital for research. To achieve credibility, literature is reviewed for proof of validity.

Moreover, proof of applicability is also tested. Practice problems in nursing require sound as well as a valid theoretical framework. This paper will explore the significance of analyzing evidence (Elkins, 2010).

How literature strengthens or weakens the merit of your selected theoretical framework and practice problem?

As mentioned above, literature is essential because it supports selected theoretical framework. Additionally, literature is essential because it validates the practice problem. Consequently, theory frameworks or practice problems that are validated can be utilized in nursing. However, theoretical frameworks and practice problems that fail validation are usually ignored or researched further for validation before they are applied in nursing practices.

This shows that literature is significant to nursing practice. It should be noted that literature from credible sources strengthens the merit of any selected theoretical framework. This is true because credible sources in nursing practice provide evidence-based practice or research-based practice on the selected theoretical framework chosen (Powers, 2010).

Additionally, credible sources provide past applications of the theoretical framework as well as the results of such applications. These applications are usually verified by professional individuals who validate the theoretical frameworks chosen.

However, literature from disputed sources or unreliable sources tends to provide weak support for the chosen theoretical framework or practice problem. In this regard, such literature is usually scantily researched or invalidated by professionals in the field of practice (Cushing/Whitney Medical Library, 2009).

Levels of evidence that is most prevalent in these articles

Evidence in strong literature materials include sources, professional bodies, as well as a validation of research-based or evidence-based practice from qualified individuals. In essence, the evidence presented in such articles is usually strong and indisputable.

It is also necessary to note that such evidence is usually under constant review for applicability in the present and new areas. It can thus be noted that the level of evidence that is most prevalent in these articles are level VI evidence. Evidence from such literature are case studies, which have recommendations (Powers, 2010).

Reasons why I think that the level of evidence is most prevalent

I believe that levels of evidence, which are most prevalent, are level VI pieces of evidence because they contain systematic reviews. Moreover, they are critically appraised for application on patients. In essence, applying weak or disputable evidence on patients may risk their lives.

Additionally, most evident in the literature includes case studies with recommendations. This ensures that the theoretical framework chosen is practicable and applicable to patients. This evidence is usually tested severally by professionals before use on patients. Additionally, they are usually thoroughly researched with great focus on risks posed to the patient in practice (Fineout-Overholt, Melnyk, Stillwell & Williamson, 2010).


Literature is essential to any theoretical framework or practice problem. Literature provides evidence for the use of any given theoretical framework or practice problem. Additionally, literature provides information on past practice or future need for a theoretical framework or practice problem. Essentially, strong literature is usually backed by credible sources.
