Chapter 4: Cardiovascular System Flashcards
Permanent catheterization
Interventional angiography procedure, in which a catheter is placed in the subclavian or jugular vein and tunneled under skin to allow for improved dialysis access.
Phlebitis
Inflammation of a vein, often associated with venous thrombosis.
Pulmonary embolus
A mass of foreign matter present in a pulmonary artery or one of its branches.
A decrease in tissue blood supply is termed:
A) Atheroma
B) Infarction
C) Ischemia
D) Necrosis
C) Ischemia
Transposition of Great Vessels
Additive/Subtractive/Both/Neither
Subtractive
Veins
any of the tubes forming part of the blood circulation system of the body, carrying in most cases oxygen-depleted blood toward the heart
Atherosclerosis
A common form of arteriosclerosis in which deposits of fibrofatty plaque or thickenings form within the intima or intermedia of large and medium sized arteries
Atrial septal defects
An abnormal opening between the right and left atria of the heart which allows mixing of oxygenated and unoxygenated blood within the atria
Capillaries
Small blood vessels connecting venues and arterioles which allow the exchange or water, gases, and nutrients within the blood
Cardiomegaly
The appearance of an enlarged heart, as indicative of many cardiovascular disorders
The heart chamber located most anteriorly and forming the anterior border of the cardiac shadow on a lateral chest radiograph is the:
- Left atrium
- Left ventricle
- Right atrium
- Right ventricle
D
Aneurysm
Additive/subtractive/both/neither
Neither
Fusiform Aneurysm
An arterial aneurysm in which the entire circumference of the vessel wall is affected.
Gated cardiac blood pool scans
A gated nuclear medicine procedure of the heart that demonstrates heart motion and the ejection of blood from the heart.
In a fetus, the ductus arteriosus connects the: A: Aorta and the superior vena cava B: Aorta and pulmonary trunk C: Right and Left Artria D: Right and Left Ventricles
B: Aorta and pulmonary trunk
Infarct
As plaques accumulate in the coronary arteries, blood supply to the heart muscle is decreased, resulting in ischemia, a local and temporary impairment of circulation caused by obstruction of circulation, and myocardial damage as an infarct, which is an area of ischemic necrosis.
Heart
The heart acts as a pump to propel blood throughout the body via the circulatory vessels.
Myocardium
The muscular layer of the heart.
Septal Defects: additive/subtractive/both/neither
Additive
Patent ductus arteriosus
Abnormal persistence of an open ductus arteriosis after birth, resulting in recirculation of arterial blood through the lungs.
Percutaneous transluminal angioplasty
Use of a specialized catheter, typically equipped with an inflatable balloon, to perform vessel repair from within the artery or vein during angiography.
Question 8: Risk factors associated with atherosclerosis include: A. Low blood sugar levels B. Hypertension C. Cigarette smoking a. A & B b. A & C c. B & C d. A, B, & C
c. B & C
Thrombophlebitis
The presence of inflammation and blood clots within a vein
Embolization
Interventional angiography procedure in which devices such as coils are used to intentionally clot off vessels, often before surgery to prevent excessive bleeding
Endocardium
The inner membrane layer of tissue lining the heart
Epicardium
The inner layer of pericardium surrounding the heart which forms an outer layer of connective tissue covering the heart
Foramen Ovale
An opening between the right and left atria of the fetal heart which should normally close at birth
How many posterior ribs should be visible on a good inspiration PA chest radiograph? A. 12 B. 10 C. 8 D. 6
B. 10
Pulmonary Embolism: additive, subtractive, both, neither
Neither
Thrombus
A blood clot that obstructs a blood vessel
Transesophageal echocardiography
A type of echocardiographic procedure in which the patient swallows a mobile, flexible probe. The hearts structure can then be readily visualized without having structures such as the skin, rib cage, and chest muscles interfere
