Iowa Registered Dental Assistant (RDA) Practice Exam

The key idea here is the level of care expected in a clinical setting. In healthcare, the standard of care is the degree of care a reasonably competent professional would provide under similar circumstances. When someone fails to meet that level—skipping a necessary safety step, misjudging a situation, or otherwise not acting with the care expected—and harm results, that is negligence. In a dental context, this could be something like not following infection control protocols or not properly monitoring a patient, which could lead to injury or illness.

Duty refers to the obligation to provide care, not the failure itself. Liability is the legal responsibility for damages. Malpractice describes professional negligence specifically, but the phrase given—that of failing to exercise the required degree of care—directly defines negligence.
