The primary purpose of palpating the popliteal pulse is to assess blood flow to the lower leg. The popliteal artery runs behind the knee, and feeling for its pulse provides important information regarding the circulation in the lower extremities. A strong, palpable pulse indicates good blood flow, while an absent or weak pulse could suggest vascular issues or blockages, thereby compromising circulation to the lower leg and potentially affecting the health of the tissues in that area. Monitoring this pulse is essential in clinical evaluations, especially when assessing conditions like peripheral artery disease or injuries that may affect blood supply.

The other choices, while relevant in a clinical context, do not pertain directly to the primary function of palpating the popliteal pulse. Evaluating nerve function typically involves different testing methods, measuring blood pressure is done at specific anatomical sites, and checking for swelling requires visual or manual assessment, not pulse palpation.
