During calibration, the technician verifies electrode response commands. Which option lists an equivalent way to phrase this?

• A. Electrode response commands
• B. Keyboard calibration
• C. Bed calibration
• D. ECG polarity verification

Answer: (A)

The main idea is confirming that the system correctly recognizes and responds to the signals from the electrodes when prompted. Verifying electrode response commands means you’re checking that the electrodes produce the expected responses to calibration prompts, ensuring the device properly interprets those signals and that the leads are functioning and contacting correctly. This is essentially the same concept as the stem’s statement, just stated in the term that directly describes the signals from the electrodes. Why the other options don’t fit: keyboard calibration would relate to input devices, not to electrode signals. Bed calibration targets the physical bed setup, not the electrode system. ECG polarity verification focuses on the directionality of the ECG leads, not on whether the electrode signals themselves respond to calibration commands.
