Final answer:
The NCLEX-RN is a standardized examination used by all U.S. state boards of nursing to evaluate if a candidate is prepared for entry-level nursing practice. The examination for registered nurse licensure is known as the NCLEX-RN and is exactly the same across all U.S. states.
Step-by-step explanation:
The examination for registered nurse (RN) licensure is indeed the same in every state in the United States. This examination is called the NCLEX-RN (National Council Licensure Examination for Registered Nurses). It is a standardized exam that each state board of nursing uses to determine whether a candidate is prepared for entry-level nursing practice. The organization responsible for the creation and administration of the examination is the National Council of State Boards of Nursing (NCSBN). While the test itself is standardized, each state may have additional requirements for licensure beyond passing the NCLEX-RN exam.
