Final answer:
A wandering baseline artifact is a type of interference that can occur during an electroencephalogram (EEG) due to various factors such as muscle movements, poor electrode contact, patient movement, or external electrical interference.
Step-by-step explanation:
A wandering baseline artifact is a type of interference that can occur during an electroencephalogram (EEG), which is a test that measures electrical activity in the brain.
This artifact can be caused by various factors, such as muscle movements, poor electrode contact, patient movement, or external electrical interference from nearby equipment.
For example, if a patient moves their head or jaw during the EEG, it can cause the electrodes to shift, resulting in a wandering baseline artifact.
