Knowledge of the levels of evidence in healthcare research is important to nurses, because this can ultimately lead to an improvement in the quality of care. Which source of information is most likely to be based on high levels of evidence?
Sources such as PubMed
Recommended readings from physicians
Comprehensive searches on Google and other search engines
Magazine and newspaper articles
The Correct Answer is A
A. Sources such as PubMed. – PubMed is a database of peer-reviewed medical literature, providing access to high-quality research and systematic reviews, often with high levels of evidence.
B. Recommended readings from physicians. – Physician recommendations may vary in quality and are not guaranteed to be based on the highest level of evidence or peer-reviewed sources.
C. Comprehensive searches on Google and other search engines. – These searches yield mixed sources of varying quality and do not necessarily prioritize high-level evidence-based research.
D. Magazine and newspaper articles. – These are typically not peer-reviewed or scientifically rigorous, often intended for the general public rather than professionals, and may not rely on high levels of evidence.

Correct Answer is A
Explanation
A. The electronic documentation section – This is the appropriate place for documenting precautions like reverse isolation, so all healthcare staff can see the need for protective measures upon entry.
B. The clinical decision support system – This system provides alerts or suggestions based on clinical data, not specifically used to document isolation requirements.
C. The picture archiving and communication system – This system stores medical imaging, not isolation precautions or patient care notes.
D. The physiological monitoring system – This is used for real-time monitoring of vital signs, not for documenting patient isolation precautions.
Correct Answer is C
Explanation
A. A nursing department determining staffing levels. – While a gap analysis could theoretically be used to assess staffing needs, it is more commonly applied to evaluate broader strategic gaps rather than specific resource allocation like staffing levels.
B. A nursing director conducting focus group interviews with five nurses. – Focus groups can be part of data collection, but they don’t constitute a full gap analysis, which requires a more structured assessment to compare current versus desired states.
C. A nursing director evaluating needs prior to transitioning to a new EHR. – A gap analysis is used here to assess current system capabilities versus the requirements for the new EHR, helping to identify what resources, training, or systems are needed for the transition.
D. A nursing leader observing nurses as they work. – Observation can inform a gap analysis but, on its own, does not constitute a complete analysis of needs or gaps in the current state versus future requirements.
