The minimum size of crystal that can typically be studied using a laboratory single crystal diffractometer is 50 x50x 50 μm. The X-ray flux from a synchrotron source is expected to be 106 times the intensity of a laboratory source. Calculate the minimum size of a cubic crystal that could be studied on a diffractometer by using this source. A neutron flux is 103 times weaker. Calculate the minimum size of crystal that could be studied by single crystal neutron diffraction. (5 points)

When nurses are confronted with ethical dilemmas that challenge their values and beliefs, what is the best source to rely on to make the right decision?

A newly licensed nurse has submitted an application, letter of interest, and resume to the human resource department of a hospital and has an interview scheduled for next week. How should the nurse prepare for this interview?

The nurse observes unsafe practice by a physician and reports it to the risk management department of the hospital. Which ethical principle does this represent?
