23
Q

Where is the femoral pulse palpated?

A

Halfway between the ASIS and the pubic tubercle.

-just inferior to inguinal ligament

24
Q

Where is the popliteal pulse palpated, and why is it difficult?

A

In the popliteal fossa.

  • difficult as it’s the deepest structure
  • knee should be flexed with foot resting to relax hamstrings
25
Q

Where is the posterior tibial pulse palpated?

A

Posterior to the medial malleolus.

26
Q

Where is the dorsalis pedis pulse palpated?

A

Lateral to the tendon of extensor hallucis longus.

27
Q

Why might it be necessary to palpate all the pulse points of the lower limb?

A

Check for differences.

-e.g. due to thrombosis/embolism

28

34
Q

Where does the small saphenous vein run?

A

Posterior leg.
