The nurse notices interference on the ECG monitor that looks like a wandering or fuzzy baseline. When encountering a strange reading from an ECG, which action should the nurse take first? A Remind the client to be as still as possible. B. Check electrodes placement. C. Request new equipment and replace electrodes. D. Tap on the electrodes to initiate a reading.
The Correct Answer and Explanation is :
Correct Answer: B. Check electrode placement.
Explanation:
When interference on an ECG monitor appears as a wandering or fuzzy baseline, the nurse’s first action should be to check the placement and condition of the electrodes. Proper electrode placement and contact with the skin are essential for obtaining an accurate ECG reading. Wandering baselines are often caused by issues such as loose, improperly placed, or dried-out electrodes.
Here’s why checking the electrodes is the best first action:
- Common Causes of Wandering Baselines:
- Poor electrode-skin contact due to dried-out gel.
- Loose or detached electrodes.
- Excessive hair, sweat, or oils on the skin.
- Incorrect placement of electrodes.
- Patient movement or respiratory artifact.
- Prioritizing Accuracy:
Checking the electrode placement allows the nurse to address the most common and easily fixable cause of baseline interference. Ensuring electrodes are secure and properly applied usually resolves the issue without the need for additional interventions. - Other Interventions:
- Option A: While reminding the client to remain still is important to reduce movement artifacts, it is not the primary cause of a wandering baseline.
- Option C: Replacing equipment may be unnecessary and time-consuming unless the issue persists after troubleshooting.
- Option D: Tapping the electrodes is inappropriate as it does not resolve the issue and could damage the equipment or worsen the interference.
- Safety and Efficiency:
Proper troubleshooting minimizes unnecessary delays or costs and avoids creating confusion or anxiety for the client.
In conclusion, when a wandering or fuzzy baseline is noted, the nurse should first check the electrode placement and ensure proper contact with the skin. This is the most effective initial step to correct the issue and obtain an accurate ECG reading.
