Which statement is TRUE regarding organ and tissue donation designation?

Answer: D — Surviving family members must consent to organ donation.

Surviving family members must consent to organ donation is true because, even if an individual has designated their wish to be an organ donor, family members are often consulted to ensure that the decision aligns with the deceased's values and wishes. This practice respects the emotional weight of the situation and acknowledges the family's involvement in the final decisions regarding their loved one. The other statements present inaccuracies about the process of organ and tissue donation. Designating a wish to donate can often be updated, but this typically involves specific legal or procedural steps rather than a straightforward online change. Paramedics do not decide what organs can be donated; rather, this determination is made by medical professionals after careful assessments at healthcare facilities. The idea that the donor registry is managed by a local library misrepresents the organizational structure; donor registries are usually maintained by health authorities or specialized organizations dedicated to organ donation.
