Which type of source would be classified as a secondary source in nursing literature?

A literature review is classified as a secondary source because it synthesizes, analyzes, and interprets findings from multiple primary research studies rather than presenting new, original research. Secondary sources are valuable for providing a broad overview of existing knowledge on a topic, summarizing trends, and identifying gaps in the literature. They help guide practitioners in understanding the bigger picture by compiling findings from various studies, thus informing evidence-based practice.

In contrast, a clinical trial report, original research article, and patient case study are all examples of primary sources. These sources present original research findings, data collection, and firsthand accounts of clinical experiences or interventions. They provide the foundational evidence needed for the development of guidelines and practices in nursing and other healthcare fields.
