Which characteristic is true about the carotid pulse?

• A. Palpable
• B. Inward deflection
• C. Changes with position
• D. Height falls with inspiration

Answer: (A)

The key idea is that the carotid arterial pulse is palpable. The carotid artery sits close to the heart and transmits the pressure wave of systole so you can feel a discrete, brisk upstroke in the neck with each beat. That palpable impulse is a fundamental, expected finding of a normal carotid pulse. An inward deflection is not a feature of the carotid arterial pulse; that description aligns more with certain venous waveforms or abnormal conditions. Likewise, in a healthy adult the height of the carotid pulse is not primarily determined by body position or by inspiration, so those statements don’t describe the carotid pulse’s normal behavior.
