A(n) ___ allows for two-way communication.

• A. Intercom System
• B. Public Address System
• C. Nurse Call System
• D. Paging System

Answer: (A)

Two-way communication means you can both send and receive audio in real time. An intercom system is built to link multiple stations so you can talk from one location and hear a response from another, enabling direct back-and-forth conversation. Public address and paging systems are designed to broadcast messages to one or many receivers, but they don’t inherently support a real-time, two-way dialogue. A nurse call system is mainly about signaling for assistance from a patient to staff, with the emphasis on a prompt response rather than ongoing two-way conversation. So, the intercom best fits the idea of true two-way communication.
