Which term describes a pulse that can only be obliterated with difficulty?

The correct term for a pulse that can only be obliterated with difficulty is a bounding pulse. A bounding pulse is characterized by a strong and forceful heartbeat that can be felt easily and may not be easily compressed or stopped by applying pressure. This type of pulse is often related to conditions such as fever, anxiety, or increased cardiac output.

In contrast, a weak pulse is typically faint and may be easier to obliterate with minimal pressure, while a thready pulse is often weak, thin, and difficult to detect. A normal pulse is one that has a regular rhythm and strength, indicating stable cardiovascular function yet not necessarily indicating the strength seen in a bounding pulse. Thus, the term bounding pulse best describes a pulse that requires significant effort to obliterate.
