Emergency Nurse Practitioner (ENP) Practice Test 2025 – Comprehensive All-in-One Guide to Exam Success

The ISINet is a modern network architecture used for emergency services, which is capable of integrating voice, video, text, and data calls to Public Safety Answering Points (PSAPs). The protocol used to deliver these calls over the network is IP Multimedia Subsystem (IMS) and Session Initiation Protocol (SIP). This protocol allows for real-time communication and efficient delivery of emergency calls to PSAPs. Unlike the other options provided, which are not specifically designed for emergency services, IMS and SIP are specifically designed and optimized for this purpose. International Postal Service is a physical means of sending mail and is not relevant to emergency services. Internet Protocol Television Protocol is used for delivering television content over IP networks and does not have any relation to emergency services. ISO Management System is a system for managing quality standards and is not directly related to emergency services or call delivery.
