E. Construct a conceptual framework - CORRECT ANSWER✔✔- B, C, E --- Rationale:
Literature reviews lay the foundation for new research studies. During the process of
conducting a literature review, information from peer-reviewed sources serve to inform the
researcher about appropriate methods, conceptual frameworks, and research questions.

clinical questions?

Case study
Qualitative
Quantitative
Historical - CORRECT ANSWER✔✔- Qualitative
The nurse locates a meta-analysis study on a clinical topic. When evaluating the research
question or hypothesis for the individual studies, what characteristic is to be expected?
A. The research questions and hypotheses should be different across studies.
B. There should be general similarities between studies' questions and hypotheses.
,C. Some studies may have research questions and other studies have hypotheses
