The nursing profession can be physically demanding. Standing and walking for long stretches, assisting in lifting patients, and staying awake for odd hours and long periods are some of the physical demands of the job. If your interviewer poses this question during your interview, you can expect some physical demands in working as a Registered Nurse for their organization. For the position you are interviewing for, make sure to research the physical demands of the job and point out how you can handle those tasks. Discussing your self-care methods can also be beneficial because being a nurse often requires being in great shape.
