Nonmaleficence is an ethical principle that emphasizes the obligation to avoid causing harm to others. It is a fundamental concept in fields like medicine and healthcare, guiding professionals to ensure that their actions do not negatively impact patients. This principle is often summarized by the phrase "do no harm," highlighting the importance of safety and well-being in decision-making. In practice, nonmaleficence requires careful consideration of the potential risks and benefits of any intervention. Healthcare providers, such as doctors and nurses, must weigh the consequences of treatments and procedures to minimize harm while promoting patient health. This principle is essential for maintaining trust and integrity in the caregiver-patient relationship.
