A nursing student has begun a clinical placement at a large hospital that serves a diverse population. The student has consequently acquired a new appreciation for the fact that nursing combines art with science. What is the clearest manifestation of the scientific basis for nursing

Answer is Providing evidence - based nursing care.

Explanation:

It should be note noted that, the development of an accumulating body of unique scientific knowledge, which makes it easier to predict the specific nursing interventions that are most likely to produce the expected or desired result, is referred to as the evidence-based practice.

It should be understood that the process of participating in continuing education and mentoring are important and beneficial, but, they are not considered as the direct manifestation of the scientific basis for nursing.

The evidence-based practice is made possible due to the scientific basis that underlies nursing.
