Which statement best describes CVP's clinical relevance?

• A. CVP measures blood glucose
• B. CVP primarily reflects fluid volume status
• C. CVP measures cognitive function
• D. CVP monitors airway pressure

Answer: (B)

Central venous pressure measures the pressure in the central venous system near the right atrium, which reflects right atrial pressure and the heart’s preload. Because preload is closely tied to intravascular volume and venous return, CVP serves as a practical gauge of fluid status and helps guide fluid management in many patients. It isn’t a measure of blood glucose, cognitive function, or airway pressure—those are assessed by other tests or monitors. Remember that CVP can be influenced by factors like intrathoracic pressure and right heart function, so it’s most useful when interpreted alongside other clinical data. In this light, CVP’s clinical relevance is best described as reflecting fluid volume status.
