By asking this question, your interviewer is simply looking to see that you are ready and able to handle tasks that are not always pleasant. As a Certified Nursing Assistant, the direct care you provide to patients can involve some tasks that some people wouldn't ever do with another person. Bathing, grooming, feeding, and bandaging patients isn't the most glamorous work but vitally important nonetheless in their care. As you prepare for this question, you need to make it clear to your interviewer that you are willing to do anything required of you in the role, even if you say that you are a bit reluctant or fearful of any certain duties.
