An EKG technician should recognize that which of the following situations could result in wandering baseline artifact on an EKG tracing? Loose electrodes Patient tremors Wating in the room apprehension

To determine which situations could result in wandering baseline artifact on an EKG tracing, let's analyze each option: 1. **Loose electrodes**: Loose electrodes can cause poor contact with the skin, leading to fluctuations in the electrical signals picked up by the EKG machine. This can result in a wandering baseline artifact. 2. **Patient tremors**: Tremors can create movement that affects the EKG tracing, but they typically cause more of a jagged or erratic line rather than a wandering baseline. However, if the tremors are mild, they could contribute to a wandering baseline. 3. **Waiting in the room apprehension**: Anxiety or apprehension can lead to physiological changes such as increased heart rate or muscle tension, which may not directly cause a wandering baseline but can contribute to overall noise in the EKG signal. Based on this analysis, the most likely causes of wandering baseline artifact are: - Loose electrodes - Patient tremors (to a lesser extent) Therefore, the situation that could result in wandering baseline artifact on an EKG tracing is primarily **loose electrodes**.
