week 6 peripheral vascular system Questions and
Answers with Solutions UPDATED!!!
ischemia - ANSWER a deficient supply of oxygenated arterial
blood to a tissue caused by obstruction
peripheral arterial disease (PAD) - ANSWER narrowing of
arteries which reduces blood flow to the extremities
usually due to atherosclerosis or a build up of plaque in the
lumen of the artery
cardinal symptom: leg pain due to intermittent claudication
(relieved by rest or smoking cessation)
treated with diet, exercise and anti platelet medication
exertion extremity pain
thinning of skin
hair loss to extremities
, Page |2
pulse weak, thready, or absent pulses
lesion sites; toes
capacitance vessels - ANSWER means that veins are able to
stretch which means that they can expand and hold more blood
when blood volume increases
incompetent valves - ANSWER lumen is so wide that the valve
cups cannot approximate leading to increase venous pressure
which further dilates the vein
peripheral venous disease (PVD) - ANSWER obstruction of
venous return of the superficial or deep veins
due to venous stasis -- inactivity, obesity, diabetes, post surgery
can be acute or chronic
cardinal sig is pain at rest and edema of extremities
