Capacity to consent means the patient can do what?

• A. Consent is valid if patient signs a form, regardless of understanding
• B. Capacity to consent means patient must be legally married
• C. Capacity to consent means the patient can understand information, reason about treatment options, and communicate a choice
• D. Capacity to consent is the same as age alone

Answer: (C)

Understanding, reasoning, and communication form what capacity to consent means. A patient has the ability to engage in a real medical decision when they can grasp the information presented, weigh the potential options and outcomes, and clearly express a choice about their care. It’s not enough to simply sign a form; that doesn't prove understanding. Likewise, capacity isn’t determined by age or marital status—some younger or older individuals can understand and decide, while others may not, depending on cognitive ability at the moment.

So, the best description is that capacity to consent involves understanding information, reasoning about treatment options, and communicating a choice.
