Which statement best differentiates carotid from jugular pulses?

Which statement best differentiates carotid from jugular pulses?

• A. Carotid shows outward deflection while the jugular shows inward deflection
• B. Carotid changes with position while the jugular does not
• C. Jugular height falls with inspiration while the carotid does
• D. Jugular is not palpable while the carotid is palpable

Answer: (A)

Carotid versus jugular pulses are distinguished by arterial versus venous origin, giving the clearest practical cue: the carotid pulse is a palpable arterial impulse with a brisk upstroke and a dome-shaped contour that shows an outward deflection on a pulse tracing. The jugular venous pulse is a venous waveform reflecting right atrial pressure, not palpable, and its tracing deflects inward and is highly influenced by breathing and position. So, the outward deflection signifies the arterial pulse, while the inward deflection corresponds to the venous pulse.
