Which of the following is a bioethical concern?

Child abuse is a serious social and legal issue, but it does not specifically pertain to bioethics. While it certainly raises ethical questions about welfare and protection, it is more aligned with law enforcement and child protection services rather than the specific concerns of bioethics, which focus on medical and biological issues.

Informed consent is indeed a crucial aspect of bioethics, as it relates to the ethical obligation of healthcare providers to ensure that patients understand the risks and benefits of medical procedures. However, it serves as a principle applicable to many medical practices and is not a specific concern in itself, unlike genetic testing, which directly embodies ethical dilemmas.

Patient confidentiality is an essential ethical principle in healthcare that protects patient privacy. While it is a significant concern within bioethics, it is broader in scope and does not specifically address the unique ethical issues that arise from genetic testing, such as the sharing of genetic information with third parties.

Sexual harassment is a social and legal issue that relates to workplace and personal conduct, but it is not a bioethical concern. Although it raises ethical questions about power dynamics and consent, it does not fall under the domain of bioethics, which focuses on the intersection of biology and healthcare ethics.
