Which statement accurately describes aging-related changes in peripheral pulses?

• A. Peripheral pulses always become easier to locate with age
• B. The dorsalis pedis and posterior tibial arteries may be difficult to locate due to arteriosclerosis or rigid arteries
• C. All peripheral pulses strengthen with age
• D. Arterial pulses disappear completely in older adults

Answer: (B)

Aging often brings stiffness and calcification of the arteries, especially in the legs. When vessels lose elasticity and become rigid or atherosclerotic, the pulses in the lower extremities—like the dorsalis pedis and posterior tibial—can become faint or hard to locate. This makes the statement that these arteries may be difficult to locate due to arteriosclerosis or rigid arteries the best description of how peripheral pulses change with age.

Pulses do not universally strengthen with age, and they don’t disappear completely in everyone. In many older adults they’re weaker or harder to find because of vascular changes, which is why this particular description fits aging best. If needed, a Doppler can help identify pulses when palpation is challenging.
