IntroductionNurses frequently work in situations where their boundaries are tested. Their response to these "tests" is a matter of professional and nursing integrity, because because of the power inherent in their professional role, they are expected to do the right thing, even if it is not always clear what “doing the right thing” can look like. Similar to the fence around the yard or the walls around the house, boundaries metaphorically mark the parameters of the professional role. (Baron, 2001; Wysoker, 2000). According to Holder & Schenthal (2007), a broad definition of professional boundaries is the “boundary that protects the space between the power of the professional and the vulnerability of the patient.” Professional boundaries are the spaces between nurses and patients, nurses and doctors, or even nurses with other multi-interprofessional health workers. Nurses' power comes from professional position, increased knowledge, role advancement and responsibility. Establishing boundaries allows the nurse to control this power differential and allows for safe connection with others to meet patient needs. Government policymakers have shown that nursing services are provided and affect career paths and education. Policies impact professional roles and boundaries of health care services. Nurses are becoming more individual in their own practice and have been at the forefront of developing new roles. The nursing profession has also faced challenges related to technological advancements in health care. By becoming better informed about decision-making regarding policies, legal standards, and ethics, nurses can address these challenges. The requirement for political, legal and ethical standards would promote better knowledge, taking into account the middle of paper to protect nurses. The standard practice here is medical directive. Medical directive means a medical instruction given to a paramedic regarding the medical management or procedure to be performed on the patient. The document must include approved procedures that may be performed by the nurse and approved by the department head. These documents should also be checked frequently to ensure they are updated and relevant to the current situation and requirements. In conclusion, crossing professional boundaries comes with many advantages and weaknesses. However, nurses must always remember that they are nurses. It is therefore essential to seek advice from the outset when an issue around professional boundaries arises and, as for the medical profession, they must value the knowledge and expertise of nurses in order to share their experience, knowledge and skills. future development of the health professional.
