Final answer:
The dental assistant would be violating Professional conduct guidelines by working outside her scope of practice, as this action goes against legal and ethical standards in healthcare. This could lead to serious consequences and disciplinary action.
Step-by-step explanation:
If a dental assistant ignored her employer's instructions and worked outside her scope of practice, she would be violating C) Professional conduct guidelines. The scope of practice is defined by law and is regulated to ensure that dental assistants perform only the tasks for which they are licensed or certified. Working outside the scope of practice can result in serious legal and professional consequences, including putting patients at risk and breaching the trust placed in healthcare professionals. Additionally, every healthcare practitioner, including dental assistants, is expected to adhere to a Code of Ethics that defines the values and responsibilities of the profession. Violating these ethical standards can damage the reputation of the individual and the practice they work for, and result in disciplinary action from the appropriate regulatory body. While workplace regulations are important and patient confidentiality is an essential part of healthcare, these are not the primary concerns when working beyond one's allowed scope of practice. The main issue at hand is adhering to professional conduct guidelines and maintaining the high standards expected in medical professions.
