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?
You selected this option
Verify and possibly readjust the placement of the sensors as incorrect positioning may be impacting the trace quality.
You selected this option
Double-check the patient's comfort and temperature as patient discomfort or cold could result in physiological responses that alter the monitor's readings.
You selected this option
Reassess the patient for potential physical causes of these anomalies, such as involuntary movements or muscle contractions, and document for further clinical review.
You selected this option
Investigate and rectify any electrical disturbances near the monitoring setup by repositioning or disconnecting non-essential electrical devices.
The observed rhythmic, sharp elevations on the cardiac monitor strip at frequent intervals suggest the presence of interference from other electrical devices, rather than stemming from the patient’s physiological activity. To resolve this, a Medical Assistant should ensure that other electrical devices, which may include personal electronics or medical machinery such as infusion pumps, are not positioned too close to the cardiac monitoring equipment. If these devices are present, they should be moved away or turned off. This type of interference would not be related to the patient's bodily functions like tremors, shivering, or an irregular heartbeat, which typically manifest with varying patterns of disturbance on the monitor.
