Nursing advocacy for patients is considered to be an essential component of nursing practice. This phenomenological qualitative pilot study explored registered nurses' lived experience of nursing advocacy with patients using a sample of three medical-surgical registered nurses. The guiding research questions were: (1) how do registered nurses practicing in the medical-surgical specialty area describe their experiences with nursing advocacy for their patients; and (2) what reflections on educational preparation for their professional roles do registered nurses identify as related to their (...) practices of nursing advocacy with their patients? Data analysis procedures were based on Moustakas' data analysis method, and Lincoln and Guba's criteria were applied for rigor. The emergent themes were: speaking out and speaking for patients; being compelled to act on unmet needs of patients; fulfillment and frustration; the patient is changed; primarily learned on the job; and confidence gained through practice. The findings increase the body of knowledge surrounding nursing advocacy as practiced by nurses. (shrink)
