During assessment of the jugular venous pressure (JVP), the advanced practice registered nurse (APRN) measures a JVP >5cm above the sternal angle. How will this finding be described?

A. Abnormal: indicating elevated right atrial pressure (central venous pressure) is correct because the normal JVP is ≤3–4 cm above the sternal angle when the patient is at a 30–45° incline. A measurement greater than 5 cm above the sternal angle indicates elevated central venous pressure (CVP), which reflects increased right atrial pressure. Causes may include right-sided heart failure, fluid overload, tricuspid regurgitation, or constrictive pericarditis. B. Normal: Indicating normal left atrial pressure is incorrect because JVP reflects right atrial pressure, not left atrial pressure. Left atrial pressure is assessed indirectly via pulmonary capillary wedge pressure, not by JVP. C. Normal: Indicating normal right atrial pressure is incorrect because a JVP >5 cm is above the normal range. Normal right atrial pressure corresponds to a JVP ≤3–4 cm above the sternal angle. D. Abnormal: indicating decreased right atrial pressure (central venous pressure) is incorrect because elevated JVP indicates increased, not decreased, right atrial pressure. A decreased JVP would be observed as flattened or nearly invisible jugular veins, which is the opposite finding.
