Not all work situations are ideal. Talk to the interviewer about how you would handle working in tough situations with limited resources and/or low morale.
Here is a sample answer "I have been accustomed to working in ideal work situations where morale is high and resources are plenty. I have, however, worked as a volunteer in third world situations. It's important to work in situations like this so that we can appreciate what we have here in America. During this volunteer time I was able to really think outside of the box when it came to care of patients. You have to utilized what you are given and keep a positive attitude."
