Which of the following is an example of how the principle of beneficence is applied to a study involving human subjects? Providing detailed information about the study to potential subjects. Ensuring that the selection of subjects is fair. Ensuring that risks are reasonable in relationship to anticipated benefits. Ensuring that subjects understand that participation is voluntary.

Answer 1

The answer is ensuring that risks are reasonable in relationship to anticipated benefits

When the principle of beneficence is applied to a study involving human subjects it is important to safeguard subjects in the experiment. No matter how important the anticipated benefits may be, the risks have to be  reasonable to protect the people involved.  

Answer 2

The right answer is:

Ensuring that risks are reasonable in relationship to anticipated benefits.

The reason why is:

The main concept of beneficence is "do no harm", different from the other aspects of beneficence is morality and ethical theory which allows for judging relative costs and risks, so in the case when harm could be inflicted in violating the principal could only take place if substantial benefit may be gained.
