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

The correct answer focuses on the Common Alerting Protocol (CAP) within the context of a Public Safety Answering Point (PSAP). In this environment, the pANI (pseudo Automatic Number Identification), which is crucial for identifying the location and callback number associated with emergency calls, is delivered in a systematic way that ensures both location data and the caller's information are routed together.

This capability is typically found in a CAS (Carrier Access Service) environment, where systems are specifically designed to handle such data efficiently, enabling quicker and more effective responses to emergency situations. The integration of voice calls with essential data like pANI allows PSAPs to receive all necessary information seamlessly, facilitating rapid response and enhancing the efficacy of emergency services.

In contrast, environments like campuses, corporate offices, or rural areas may lack the specialized infrastructure or technology required for such integrations, making CAS the most fitting environment for this context.
