Final answer:
Reciprocity is a true aspect of nurse licensing allowing nurses to be endorsed by states other than where they initially obtain their license, via mechanisms such as the Nursing Licensure Compact.
Step-by-step explanation:
True, reciprocity is indeed the process that allows a nurse to apply for and be endorsed as a registered nurse by a state different from the one where they originally obtained their license. This arrangement is especially important in allowing for a flexible nursing workforce, capable of crossing state lines, particularly in the United States where nursing regulation is managed state by state. Nurses must meet the requirements of the Nursing Licensure Compact (NLC) for multistate licensure which streamlines the process of working in multiple states for nurses who qualify.
