Final answer:
The correct credentialing verification process is that hospitals verify a healthcare professional's licensure and competence, from the primary source or a CVO, at initial granting, renewal, and revision of privileges and at license expiration.
Step-by-step explanation:
During the process of credentialing, a hospital is responsible for verifying the credentials of healthcare professionals before they are allowed to practice within the facility. The correct statement is C: the hospital verifies, from the primary source whenever feasible, or from a credentials verification organization (CVO), the applicant's current licensure at the time of initial granting, renewal, and revision of privileges and at the time of license expiration, as well as the applicant's relevant training and current competence. This process is critical in ensuring that healthcare providers have the necessary qualifications and remain competent to provide care, thus reflecting the concept of credentialism.
