Step-by-step explanation:
The Sigma Theta Tau study of 20,000 healthcare publications revealed that nurses were rarely cited, discouraging the perception of them as expert clinicians. The study found that nurses were not frequently portrayed as expert clinicians and their role in healthcare was often downplayed. This lack of representation may contribute to misconceptions about the skills and expertise of nurses.
