Which pulse points are critical during a lower extremity assessment?

• A. Femoral and popliteal pulses
• B. Dorsalis pedis and posterior tibial pulses
• C. Radial and ulnar pulses
• D. Axillary and brachial pulses

Answer: (B)

In the context of a lower extremity assessment, the dorsalis pedis and posterior tibial pulses are indeed critical. These pulses are located in the lower leg and foot, and their assessment is essential for evaluating the perfusion and vascular status of the lower extremities.

The dorsalis pedis pulse can be palpated on the dorsum of the foot, between the first and second metatarsal bones, and indicates blood flow to the anterior part of the foot. The posterior tibial pulse is found behind the medial malleolus of the ankle and reflects blood flow to the posterior and plantar aspects of the foot. Assessing these pulses allows healthcare providers to determine if there are any circulation issues, peripheral artery disease, or other vascular conditions affecting the lower limbs.

In contrast, while the femoral and popliteal pulses (another option) are important, they are higher in the vascular system and do not provide as direct an assessment of the lower extremities as the pulses at the ankle and foot. The radial and ulnar pulses, and the axillary and brachial pulses, are relevant to the upper extremities and not applicable to the lower extremity assessment. Thus, the choice focusing on the dorsalis pedis and
