To check for jugular venous distention, which head position is used?

• A. 90 degrees
• B. 45 degrees
• C. Sit them straight up
• D. Raise the feet

Answer: (B)

Visualizing jugular venous distention depends on getting the neck veins to present their pulsations clearly, which is best achieved by a specific head-of-bed angle. Elevating the head to about 45 degrees places the right atrium closer to the chest wall and reduces glare from overlying tissues, allowing the internal jugular venous pulsation to be seen above the clavicle more reliably. If you’re too flat, the pulsation can be hard to distinguish or masked by surrounding structures; if you’re too upright (like at 90 degrees), the vein can collapse and the pulsation becomes difficult to observe. Raising the legs changes venous return rather than the central venous pressure you’re trying to gauge, so it doesn’t aid JVD assessment. That’s why the standard position is approximately 45 degrees.
