Which statement best describes biotelemetry?

Which statement best describes biotelemetry?

• A. It measures heart rate only.
• B. It records data locally and does not transmit.
• C. It monitors environmental sensors unrelated to the patient.
• D. It measures vital signs and transmits data to a distant terminal

Answer: (D)

Biotelemetry is about remotely collecting a patient’s physiological data and transmitting it to a distant location where clinicians can monitor it. Sensors attached to or worn by the patient continuously measure vital signs—heart rate, rhythm, respiratory rate, blood pressure, oxygen saturation, and more—and this information is sent wirelessly to a distant terminal for real-time review or later analysis. This capability is what makes biotelemetry useful during transport or in settings where on-site monitoring isn’t feasible, because it provides continuous data and alerts to clinicians far away. The other statements fall short because they either describe data that isn’t being transmitted, limit the data to a single parameter, or refer to sensors unrelated to the patient. The true essence is measuring vital signs and transmitting that data to a distant terminal.
