A nurse is teaching a class about professionalism. The nurse should include that leaving a computer terminal unattended after logging on is an example of which of the following?

The correct answer is B: Unprofessionalism. Leaving a computer terminal unattended after logging on is unprofessional because it violates patient privacy and confidentiality. It exposes sensitive information to unauthorized individuals, compromising patient trust and confidentiality. Negligence (A) would involve a failure to provide proper care or attention, which is not the case here. Malpractice (C) refers to professional misconduct or negligence, typically involving patient care, which is not directly related to the scenario. Defamation of character (D) involves making false statements that harm someone's reputation, which is unrelated to leaving a computer terminal unattended.
