What distinguishes peripheral venous access from central venous access?

Peripheral venous access is characterized by the use of veins located in the arms or hands for the administration of fluids, medications, or other therapies. This method is typically preferred for its ease of access and is commonly utilized in various healthcare settings for a wide range of patients.

The choice of veins in the arms or hands is practical because these areas are generally more accessible and provide sufficient blood flow for the administration of IV therapies. In contrast, central venous access involves the insertion of a catheter into larger veins, often in the chest or neck area, allowing for administration of fluids and medications directly into the central circulation. This difference in site selection plays a crucial role in determining the uses and limitations of each access method.

While peripheral access may indeed be associated with less discomfort or pain, this can vary based on the individual and the situation. Utilizing peripheral access primarily for short-term use (as suggested by another choice) is also a common practice; however, the defining factor that clearly delineates peripheral from central venous access is specifically the anatomical location of the veins accessed. Therefore, identifying peripheral access as employing veins in the arms or hands accurately reflects a fundamental aspect of IV therapy practices. It emphasizes the basic anatomical differences that are essential in guiding clinical decisions regarding vascular
