Nurs 6633 Week 7 Disorders of the Circulatory System(updated)
areas of typical aneursyms Correct Answers - brain; if leaks
and ruptures can causes S/S of stroke (weakness on one side of
the body, change in consciousness, sudden headache)
- aorta; due to constant stress on vessel wall, especially from
HTN
areas of typical aortic aneurysms Correct Answers - if gradual
and stays small there will be no S/S
- abdominal aortic aneurysm (AAA); often found by physical
exam of the abdomen; a pulsatile mass palpated with abdominal
or back pain
- thoracic aortic aneurysm; usually found accidentally by x-ray;
if any S/S chest pain and/or back pain
arterial disorders Correct Answers - arterial insufficiency from
lack of amount of O2 getting to the distal tissues (ischemia)
- almost always due to atherosclerosis
Arterial disorders lead too? Correct Answers ischemic
problems, can apply ischemic pattern to any diseased artery,
arteriole or capillary in the body and the tissue they serve.
arterial disorders related to atherosclerosis Correct Answers 1.
peripheral artery disease (PAD)
2. arterial thrombi and emboli
3. aneurysms
4. hypertension
5. coronary artery disease
,barely palpable and thready pulse Correct Answers low blood
pressure and/or the arteries are too narrow to maintain good
pressure
BP cuff sounds Correct Answers - occlusion of an artery in the
arm leads to high pressure, as the pressure is released, the
pressure at which the first sound is heard is the pressure in the
arteries during SYSTOLE
-when the cuff pressure continues to go down and becomes less
than the diastolic pressure, no pulse is heard; when sounds stop
this is the pressure in the arteries during DIASTOLE
cardiovascular Correct Answers the heart and its vessels
cholesterol levels Correct Answers should be a ratio of 3:1 or
lower for a low risk of CAD (high cholesterol to total
cholesterol)
circulatory system Correct Answers cardiovascular and
peripheral vascular systems together
commonalities of arterial disease in ALL parts of the body
Correct Answers - alteration in vasomotor tone; loss of
flexibility/responsiveness leading to constant constriction &
brittleness
- non-patent lumen; blockage material like fats or clots on walls
Contributing factors of CVI Correct Answers - aging, inherited
disposition, obesity, pregnancy, job issues
, - lack of assistance from musculature (poor muscle tone due to
immobility or inactivity)
CVI edema Correct Answers causes mild to moderate
discomfort but over time can also cause dry, tight skin, often
with brown discolorations due to a lack of nutrients from the
blood flow. if very severe, the cells start malfunctioning and
break down especially in bony areas. (venous stasis ulcers)
CVI varicose veins Correct Answers the increased hydrostatic
pressure can also cause back flow pressures in surface veins that
become twisted and distorted.
Describe the forward flow of blood Correct Answers Blood
comes in from the Super Vena Cava and Inferior Vena Cava into
the Right Atrium --> Tricupsid Valve --> Right Ventricle -->
Pulmonic Valve --> Pulmonary Artery --> Pulmonary Capillary
Beds --> O2 and Co2 are exchanged in--> oxygenated Blood
Comes through Pulmonary Venules --> pulmonary veins--> Left
Atrium --> Mitral Value --> Left Ventricle --> Aortic Valve -->
Aorta--> Arterial System (o2 moves to the heart, brain and
tissues)
Arterioles in tissue --> capillaries in tissue (gas exchange) -->
venuoles--> veins --> SV or IV --> RA
diastolic pressure Correct Answers pressure being exerted in
the arteries when the heart is resting (diastole)
estrogen from BCPs can... Correct Answers increase the levels
of certain clotting factors
