Which pulse location should the nurse palpate when assessing the top of the client's foot?

When assessing the top of the client's foot, the nurse should palpate the dorsalis pedis pulse. The dorsalis pedis artery is located on the top of the foot, and it can be felt as a pulse between the first and second metatarsal bones, just lateral to the extensor hallucis longus tendon. This pulse provides essential information about the arterial circulation to the foot and is critical for assessing peripheral circulation in patients, especially those with conditions that may compromise blood flow.

The posterior tibial artery, while important for assessing lower limb circulation, is palpated behind the medial malleolus, not on the top of the foot. The popliteal pulse is found behind the knee, and the brachial pulse is located in the arm, which makes them unsuitable for assessing the top of the foot. Hence, the correct choice directly relates to the anatomical location and clinical significance of assessing foot circulation.
