Question

which artifact is most likely caused by other electrical equipment in the room? a wandering baseline b somatic tremor c interrupted baseline d 60 - cycle interference

Explanation:

• Wandering baseline (A) is often due to electrode issues or patient movement, not electrical equipment.
• Somatic tremor (B) comes from muscle activity/tremors, not electrical interference.
• Interrupted baseline (C) may relate to disconnections or other non - electrical interference issues.
• 60 - cycle interference (D) is typically caused by electrical interference from other electrical devices in the room (as the 60 - cycle frequency is related to electrical power systems, and other equipment can introduce this interference).

Answer:

D. 60 - cycle interference
