A patient undergoing a routine cardiac monitoring procedure appears anxious and is taking deep, regular breaths. Subsequently, the tracing shows an undulating baseline instead of the expected steady trace. What is the most appropriate step to rectify this so that a reliable recording can be obtained?
Enhance the calibration of the device to compensate for the fluctuating tracing.
Reassure the patient and instruct them to breathe calmly and regularly before continuing the procedure.
Inspect the electrodes for any detachment that might be creating interference.
Remove and reapply all the leads in anticipation that they are malfunctioning.
