NTA Telemetry Equipment and Technology Flashcards

What is the most appropriate first action when a telemetry monitor displays a 'leads off' alarm?

Answer: Check the patient and verify electrode placement

A 'leads off' alarm requires direct patient assessment to confirm stability and inspection of all electrode and lead wire connections.

What does adjusting the 'gain' setting on a telemetry monitor change?

Answer: The amplitude (height) of the waveform displayed on screen

Gain controls the vertical size of the displayed waveform; increasing gain makes waves appear taller without altering the actual cardiac signal.

How often should telemetry electrodes typically be replaced on a continuously monitored patient?

Answer: Every 24–72 hours or per facility protocol

Electrode gel dries out over time, reducing adhesion and signal quality, so replacement every 24–72 hours is standard practice.

If a telemetry transmitter displays a weak signal, what should be checked first?

Answer: Battery level, electrode contact quality, and patient proximity to the receiver

Weak signal is most commonly caused by a low battery, poor electrode contact, or the patient being at the edge of the transmission range.

Which situation can trigger a false asystole alarm on a telemetry monitor?

Answer: A detached electrode or complete signal loss

A detached electrode or total signal loss produces a flat line identical in appearance to true asystole, generating a false cardiac arrest alarm.

What is the purpose of the 'memory' or 'recall' function on a telemetry monitor?

Answer: To retrieve and review previously recorded cardiac rhythm data

The recall function retrieves stored rhythm data so technicians and clinicians can review, document, and report rhythm events that occurred earlier.
