On reviewing a patient's cardiac monitor strip, you observe rhythmic, sharp elevations happening at intervals much shorter than the patient's actual pulse. What should be your first action in troubleshooting this anomalous pattern on the monitor?
Verify and possibly readjust the placement of the sensors as incorrect positioning may be impacting the trace quality.
Double-check the patient's comfort and temperature as patient discomfort or cold could result in physiological responses that alter the monitor's readings.
Investigate and rectify any electrical disturbances near the monitoring setup by repositioning or disconnecting non-essential electrical devices.
Reassess the patient for potential physical causes of these anomalies, such as involuntary movements or muscle contractions, and document for further clinical review.
