Which statement about Tuskegee Phase II (1936-1965) is accurate?

• A. No medical student involvement.
• B. Penicillin was provided to all participants from the start.
• C. The study authorized spinal taps but did not obtain informed consent.
• D. Participants were informed and consented to all procedures.

Answer: (C)

The main idea being tested is informed consent and respecting participants’ autonomy in research. In the Tuskegee Phase II study, invasive procedures such as spinal taps were carried out without obtaining proper informed consent. The men were not told the true purpose of these procedures or the study’s real nature, and they were misled about treatment goals. This reflects a fundamental breach of ethical standards: participants should be fully informed about what is being done to them and consent to it before any procedure. Additionally, even after effective treatment (penicillin) became available, participants did not receive it, underscoring the violation of beneficence and respect for persons.

The other statements don’t fit because medical student involvement did occur, penicillin was not provided from the start, and participants were not informed and consented to all procedures.
