Sept 15 - PV Exam Flashcards
Define terms arterial occlusion, arteriosclerosis, atherosclerosis, arteriostenosis, thrombus, embolus, and aneurysm.
arterial occlusion: full blockage of an artery
arteriostenosis: partial blockage of an artery
atherosclerosis: collection of fatty deposits in arteries
arteriosclerosis: dec elasticity/hardening of arteries
thrombus: clot formed in vessel
embolus: mobile blood clot or other object in vessel
aneurysm: weakening with bulging of arterial wall
What questions are important when taking a history for a PV exam?
Pain in limbs? Pain during exercise? Cold extremities? Edema? Varicose veins? Surgery or trauma?
If an enlarged node or mass is noted, what is important to ask about?
Was it slow or quick onset?
Is it tender or non-tender?
What skin changes may be noted on physical exam?
temp, hair loss, lesions, color changes, ulcers, edema.
What are the three major risk factors for a PE?
surgery, cancer, travel
How is the popliteal pulse best palpated?
patient laying flat with knee slightly bent
How and where is the posterior tibialis palpated?
Just posterior to medial malleolus with foot relaxed.
Describe the grading system of pulses.
3+ = bounding 2+ = normal 1+ = diminished 0+ = absent
Describe Allen’s Test.
Occlude radial and ulnar arteries while patient clenches fist - palm will turn pale
Release ulnar artery - color should return < 5 sec. This is a normal finding described as a positive test.
Describe Buerger’s Test
Patient lays supine with legs elevated at 60 deg until color leaves their feet
Pt sits up with feet dangling - color should return in 10-15 sec.
Describe the ankle brachial index (ABI)
Most important bedside test for arterial insufficiency. Take BPs in all 4 extremities - ratio of highest ankle SBP to average arm SBP is calculated.
Describe the findings of the ankle brachial index.
> 1.4 = calcification or vessel hardening 1.0 - 1.4 = normal 0.9 - 1.0 = acceptable 0.8 - 0.9 = mild disease 0.5 - 0.8 = moderate disease < 0.5 = severe disease
Describe the grading scale for evaluating pitting edema.
0+ = absent 1+ = 2mm depression that disappears rapidly 2+ = 4mm depression that disappears in 10-15 sec 3+ = 6mm depression lasting > 1 min 4+ = 8mm depression lasting > 1 min
Describe physical exam findings consistent with venous stasis, aka venous insufficiency.
Everything below line of demarcation is swollen and red with skin breakdown.
What is Raynaud’s phenomenon?
blanching of distal extremities - can cause necrosis if severe
