A nurse is teaching a class about the novice-to-expert model for nursing competence to a group of nurses.
A nurse who has some experience but still requires clinical support is in which of the following stages of competence?

Choice A rationale:
Quality of practice involves the nurse's competence in providing care to patients and ensuring that the care meets established standards. Violating the quality of practice standard would typically involve issues related to the quality and safety of care provided. In this scenario, the nurse's violation is related to accessing a client's medical record without being involved in their care, which is an ethical breach rather than a violation of the quality of practice standard.
Choice B rationale:
Code of ethics is the standard of professional performance that the nurse is violating. Accessing a client's medical record without being involved in their care is a violation of the ethical principles outlined in the Code of Ethics for Nurses. This action breaches patient confidentiality and privacy, which are fundamental ethical obligations for nurses.
Choice C rationale:
Collaboration involves working effectively with other healthcare professionals to provide optimal patient care. Violations of the collaboration standard would typically involve issues related to teamwork, communication, and interdisciplinary relationships. The scenario described does not pertain to collaboration but rather concerns ethical conduct.
Choice D rationale:
Evidence-based practice refers to the integration of current research evidence into clinical decision-making and patient care. Violations of evidence-based practice would involve not following the latest research and best practices in patient care. In this case, the nurse's violation is related to ethical principles and patient privacy rather than evidence-based practice.
