A single lead used for this purpose is called a ____ _____.

• A. Monitoring Lead
• B. Recording Lead
• C. Lead II
• D. Standard Limb Lead

Answer: (A)

A single lead used for watching the heart's rhythm in real time is called a monitoring lead. This term describes the purpose: continuous observation on a bedside monitor to detect any rhythm or rate changes. It’s about ongoing surveillance rather than capturing a full diagnostic tracing.

The other options don’t fit as well for this purpose. A recording lead isn’t a standard label used to designate a lead kept on a patient for continuous monitoring, and Lead II is a specific view among the limb leads rather than a general term for a lead used to monitor. A Standard Limb Lead refers to one of the classic limb leads (I, II, or III) as a group, not to the generic concept of a single lead used for ongoing monitoring.
