Emergency Nurse Practitioner (ENP) Practice Test

What distinguishes RX only sites in a radio system design?

1. They are designed for receiving but not transmitting signals

2. They have enhanced coverage areas compared to other sites

3. They operate on a unique radio frequency band

4. They are designed exclusively for emergency service signals

The correct answer is: They are designed for receiving but not transmitting signals

In the context of a radio system design, the defining characteristic of RX only sites is that they are specifically set up to receive signals without transmitting any themselves. This design is typically employed in scenarios where receiving critical information, such as alerts or emergency signals, is paramount while eliminating the complexity and potential interference of transmission capabilities. While RX only sites may indeed receive emergency service signals, they are not exclusively designed for that purpose; they could be utilized in other communication systems as well. Enhanced coverage areas pertain more to the overall design of the system rather than specifically to RX only sites. Additionally, operating on a unique radio frequency band is not inherently a feature of RX only sites, as they can operate on the same frequencies as other sites; it is their receiving-only capability that truly distinguishes them.
