Which term describes sources of supply located within a medical facility?

The term that best describes sources of supply located within a medical facility is internal. This designation indicates that the supplies are stored or managed on-site, allowing for immediate access by healthcare providers. Internal sources streamline the logistics of supply chain management within the facility, ensuring that essential medical supplies are readily available for patient care without the need for external procurement processes.

In contrast, the external category refers to suppliers or warehouses outside the facility, which would involve more complex logistics, potential delays in delivery, and could be less efficient in emergencies when immediate supplies are needed. The other terms, primary and secondary, typically pertain to the classification of supplies based on their usage or role in patient care, rather than their location within or outside a facility. Thus, recognizing "internal" as the correct term emphasizes the importance of on-site resources in the effective delivery of medical services.
