Which of the following scenarios embodies the concept of negligence?

Negligence in a medical context refers to the failure to provide the standard of care that a reasonably competent healthcare professional would provide, which ultimately results in patient harm. Scenario B illustrates negligence because it involves a failure to deliver necessary care, which could directly harm the patient. This failure could stem from a lack of appropriate action, such as not diagnosing a condition, not following up on test results, or ignoring a patient's risk factors, all of which could lead to negative health outcomes.

In contrast, intentional harm to a patient points to a deliberate act, which is not negligence but rather a violation of ethical and legal standards. Accidental disclosure of patient information relates more to a breach of confidentiality and privacy laws, not necessarily negligence in providing care. Deliberate misinformation provided to a patient involves intentional deceit, which also falls outside the realm of negligence. Overall, negligence is characterized by a lack of intent to harm but results in harm due to carelessness or inaction, making scenario B the embodiment of this concept.
