Gerontological Nursing Certification (GERO-BC) Practice Exam

The ability to understand and process medical information is decisional capacity. This concept refers to a person’s cognitive ability to grasp the relevant facts about a medical option, appreciate the potential consequences, reason about the choices, and clearly communicate a preference. Capacity is decision-specific and can fluctuate with factors like pain, delirium, medications, or illness, so it may vary over time or between different medical decisions. In practice, informed consent relies on decisional capacity but is the broader process of disclosure, understanding, voluntariness, and agreement to a plan. A living will and documents like 5 Wishes express a person’s preferences for future care, but they do not define or measure current ability to understand medical information.
