Which example demonstrates the principle of beneficence in research studies?

The principle of beneficence in research studies is centered around the idea of maximizing benefits while minimizing harm to participants. This principle dictates that researchers have an ethical obligation to ensure that the potential benefits of their research outweigh any risks involved.

The correct example illustrates this by emphasizing the importance of ensuring reasonable risks relative to anticipated benefits. In practice, this means that researchers need to carefully assess the potential positive outcomes of their study against the risks that participants might face. For instance, if a study involves a certain level of risk, the anticipated benefits should be significant enough to justify those risks.

This ethical consideration is fundamental in research involving human subjects, as it aims to protect participants from unnecessary harm while providing them with valuable research outcomes. Therefore, assessing the risk-benefit ratio is a key aspect of conducting ethical research, aligning perfectly with the principle of beneficence.
