**Question:** Ethical principles that require health professionals to fully inform their patients and protect their confidentiality is the principle of-

A. Respect for autonomy
B. Beneficence
C. Non-maleficence
D. Justice

**Core Concept:**
The principle under discussion pertains to the ethical guidelines that govern healthcare professionals' interactions with patients. These principles ensure that healthcare providers act in the best interest of their patients and uphold certain moral values in their practice. In this context, health professionals are expected to respect patient autonomy, provide beneficence, avoid causing harm (non-maleficence), and uphold justice in their actions.

**Why the Correct Answer is Right:**
The correct answer, C. Non-maleficence, is a fundamental aspect of medical ethics that mandates healthcare professionals to not cause any harm or damage to their patients. This principle is crucial in ensuring that healthcare providers act in the best interest of the patient and avoid any actions that may cause detrimental effects.

**Why Each Wrong Option is Incorrect:**
A. Respect for autonomy (Option A) is about empowering patients to make informed decisions regarding their healthcare, but it does not specifically address protecting patient confidentiality or ensuring full disclosure of information.
B. Beneficence (Option B) is about acting in the best interest of the patient, which is partially related to the principle discussed, but does not encompass the full scope of protecting patient confidentiality and providing complete information.
D. Justice (Option D) involves distributing healthcare resources fairly among patients and ensuring equitable treatment, but it does not specifically relate to the principles of protecting patient confidentiality and disclosing comprehensive information.

**Clinical Pearl:**
In medical practice, it is essential for healthcare professionals to uphold the principle of non-maleficence, which entails not causing harm or doing no harm to patients. This principle should guide the actions of healthcare providers in maintaining patient confidentiality and providing comprehensive information, ensuring the best possible care and outcomes for their patients.
