A charge nurse is discussing evidence-based practice (EBP) and the hierarchy of evidence with a newly licensed nurse.
Which of the following examples should the nurse provide when discussing Level I evidence?

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.

The correct answer is Choice B: A client who has a family history of breast cancer is scheduled for a mammogram.

Choice A rationale:

Receiving an influenza vaccination is an example of primary prevention, which aims to prevent the onset of disease.

Choice B rationale:

Scheduling a mammogram for a client with a family history of breast cancer is an example of secondary prevention. Secondary prevention involves the early detection and treatment of disease to reduce the impact of the disease. Mammograms help in the early detection of breast cancer, which can significantly improve treatment outcomes.

Choice C rationale:

Not scheduling tests for an asymptomatic client does not relate to secondary prevention. Secondary prevention involves screening and early detection of diseases in at-risk populations.

Choice D rationale:

Scheduling an echocardiogram for a client with heart failure is an example of tertiary prevention. Tertiary prevention aims to reduce the impact of an ongoing illness or injury that has lasting effects by helping patients manage long-term, complex health problems.
