Final answer:
To be eligible for the nurse practitioner program, one must generally be a Registered Nurse with a bachelor's degree in nursing. LPNs and Nursing Assistants typically need to attain RN status first, and MDs are on a separate track.
Step-by-step explanation:
The eligibility criteria for the nurse practitioner program typically require that an applicant must be a Registered Nurse (RN) with a bachelor's degree in nursing (BSN). Licensed Practical Nurses (LPNs) and Nursing Assistants usually do not meet the education requirements for direct entry into a nurse practitioner program; they would first need to become RNs. Medical Doctors (MDs), while highly trained in the field of medicine, follow a different educational and professional track and thus would not enroll in a nurse practitioner program designed for nurses.
