What is the primary function of an Institutional Review Board (IRB)?

The primary function of an Institutional Review Board (IRB) is to review research proposals for ethical violations. IRBs are committees established to protect the rights and welfare of human research subjects involved in research studies. They evaluate research proposals to ensure that ethical standards are maintained, informed consent is obtained, risks to participants are minimized, and that the benefits of research outweigh any potential risks. The IRB plays a crucial role in ensuring that research is conducted in accordance with applicable regulations and ethical guidelines, thus upholding the integrity of the research process and the safety of participants.

The other options do not align with the primary responsibilities of an IRB. Marketing strategies, hospital administration, and patient care protocols are not within the scope of an IRB's duties. Instead, these areas are typically managed by different departments within healthcare settings that focus on operations, administration, and patient management.
