Final answer:
MECP appointees must complete an undergraduate degree program at a university or college to obtain a Bachelor of Science in Nursing. This prepares them to qualify for a commission as a naval officer and to take the NCLEX-RN licensing examination.
Step-by-step explanation:
The school that must be completed by MECP (Medical Enlisted Commissioning Program) appointees is a university or college where they can obtain a Bachelor of Science in Nursing (BSN). This is an undergraduate degree program that provides the necessary education for a nurse to then qualify for a commission as a naval officer. MECP appointees will have to meet certain academic requirements, which typically involve completing prerequisites and nursing-related coursework essential for earning their degree and preparing for the NCLEX-RN licensing examination, which is a requirement for practice as a registered nurse (RN) in the United States.
