• C. The capacity to memorize all medical terminology.
• D. The willingness to follow physician orders without question.

Answer: (B)

Health literacy is the ability to obtain, read, understand, and use health information to make appropriate health decisions. It goes beyond reading speed or memorizing medical terms; it includes interpreting instructions, labels, and risk information, and applying that knowledge to choices about care. It also involves navigating the health system, communicating with providers, and knowing when to ask questions. People with solid health literacy can understand medication labels, follow treatment plans, weigh options, and participate in decisions with clinicians. The other ideas—speed of reading, memorizing terminology, or following orders without question—don’t capture the essential ability to comprehend and apply information to act safely and effectively. For example, understanding how to take a prescription correctly and recognizing potential side effects demonstrates health literacy in action.
