Which element is NOT described as part of extra protections for informed consent in vulnerable populations?

• A. Simplified language
• B. Independent consent advocates
• C. Ongoing re-consent
• D. Parental consent waivers

Answer: (D)

The idea here is about safeguards that strengthen informed consent for people who may be vulnerable. Simplified language makes the study details easier to understand, which helps participants truly grasp what they’re agreeing to. Independent consent advocates provide an external, impartial voice to protect the participant’s interests and ensure that consent remains voluntary. Ongoing re-consent recognizes that consent isn’t a one-time event; as new information appears or circumstances change, participants can reaffirm or withdraw their consent.

Parental consent waivers, by contrast, do not add a protective layer. They remove or bypass an important safeguard for minors—requiring parental permission—under circumstances that can reduce protection rather than enhance it. So this option isn’t described as an extra protection for informed consent in vulnerable populations.
