decreased or absent pedal pulses with cool or cold foot
the presence of stasis ulcers over the medial malleolus
skin atrophy and pallor with elevation of the affected leg
decreased circumference in the affected leg due to venous constriction
Number 2 is correct.
Rationale: Stasis ulcers often form as a result of edema or minor injury to the leg. They occur more often medially than laterally over the malleolus of the affected limb. Decreased or absent pulses with cool or cold feet is a finding of arterial ulcers. Skin atrophy and pallor with elevation are another indication of arterial ulcers. Edema is often present due to valvular damage from the backup of blood and venous hypertension.
