Which right is ensured by informed consent?

• A. Right to withdraw from the study at any time.
• B. Right to a guaranteed cure
• C. Right to free treatment regardless of risk
• D. Right to choose the research outcome

Answer: (A)

Informed consent centers on respecting a person’s autonomy to decide about participation in research. A fundamental part of that autonomy is the ability to withdraw at any time without penalty. If someone feels uncomfortable, changes their mind, or learns new information, they should be free to leave the study and stop participating, and this choice should be supported by the consent process. This withdrawal right ensures participation remains voluntary throughout the study.

The other aims listed aren’t guaranteed by informed consent. A cure is not promised by simply consenting to participate, as outcomes depend on the study design and responses. Free treatment regardless of risk isn’t an entitlement—studies must weigh risks and benefits, and participation isn’t a blanket guarantee of treatment. Finally, individuals don’t control the research outcomes; the purpose of the study is to investigate questions and produce results, not to grant participants the power to decide those results.
