Study Notes

Assessment of Peripheral Vascular System

Posterior tibial pulse is palpated between the malleolus and Achilles tendon; no pulse at lateral malleolus
65-year-old patient experiencing left calf pain during exercise, consistent with ischemia due to partial arterial blockage
Venous blood returns to heart through intraluminal valves, contracting skeletal muscles, and pressure gradients
Superficial veins responsible for most venous return in arm
Great saphenous vein can be removed for open-heart surgery without harming circulation if femoral and popliteal veins remain intact
Prolonged bed rest is a high risk factor for venous disease
Lymph flow is slow compared to blood flow, propelled by skeletal muscles and pressure changes
Enlarged right epitrochlear lymph node indicates the need to examine lower arm and hand for infection or lesions
Inguinal nodes in the groin drain most of the lymph of the lower extremities
In an assessment of a patient with an infection in the left foot, expect to see enlarged and tender inguinal nodes
Lymph vessels have valves, ensuring one-way flow from tissue spaces to bloodstream
The epitrochlear nodes are located in the antecubital fossa and drain the hand and lower arm
