100
This type of flow is in seen vessels feeding the abdominal organs
What is "low resistant" flow?
100
This abnormal growth has three main features: (1) is located in the common carotid artery bifurcation (2) can cause widened carotid bifurcation angle (3) tumor blood flow is extremely rich
What is "carotid body tumor"?
100
The vertebral arteries fuse at the pontomedullary junction to form this artery
What is "basilar artery"?
100
These are the names of the two superficial veins of the upper extremity
What are "cephalic and basilic veins"?
100
This is often cited as the primary weapon in the infection control arsenal in the health care setting
What is "hand washing"?
200
This type of flow is always abnormal in any branch of the portal vein, and is common in patients with liver disease
What is "hepatofugal (away from the liver) flow"?
200
The most helpful diagnostic ultrasound finding for this disease is the demonstration of a membrane within the artery in the longitudinal and transverse views
What is "dissection"?
200
This word describes a condtion where there is constriction or narrowing of one or more of the major basal intracranial blood vessels. It is often caused by the constriction prompted by chemical signals from hemorrhage as it breaks down.
What is "vasospasm"?
200
The cephalic vein joins this deep vein
What is the "axillary vein"?
200
This relates to a test's ability to identify positive results
What is "sensitivity"?
300
This pulsed Doppler index is often elevated when sampling the parenchymal arteries of the kidney in cases of renal vein thrombosis
What is "resistance index"?
300
Hemodynamically significant stenosis or occlusion of this vessel always causes abnormal blood flow in the right vertebral and right common carotid arteries
What is the "innominate artery"?
300
The transcranial pulsed Doppler sample volume is positioned at approximately 55mm depth via the temporal area and moved until this vessel is located
What is the "middle cerebral artery"?
300
This is often inserted in a peripheral vein such as the cephalic vein, basilic vein, or brachial vein, and then advanced through increasingly larger veins toward the heart until the tip rests in the distal superior vena cava or cavoatrial junction
What is a "PICC (peripherally inserted central catheter)"?
300
Some 3 to 20% of inpatients do this at least once during their hospital stay resulting in injuries, increased lengths of stay, malpractice lawsuits, and more than $4,000 in excess charges per hospitalization.
What is "fall"?
400
DOUBLE JEOPARDY!!!!!! This term describes compression of the left renal vein between the aorta and the superior mesenteric artery
What is "nutcracker (or renal vein entrapment) syndrome"?
400
The medial type of this disease is by far the most common and is classically diagnosed on the basis of a "string of beads" appearance on angiography and/or power Doppler
What is "fibromuscular dysplasia"?
400
The circle of Willis is formed by the posterior cerebral, posterior communicating, internal carotid, anterior cerebral as well as these arteries
What are "anterior communicating arteries"?
400
DOUBLE JEOPARDY!!!!!! The veins that travel along their companion arteries are categorized as this type of vein
What are "deep veins"?
400
The following formula is used to calculate this type of statistic: true negatives/(true negatives + false positives)
What is "specificity"?
500
This disease accounts for less than 10 percent of cases of renal-artery stenosis, and 90 percent of these cases involves the media. It tends to affect females between 15 and 50 years of age and frequently involves the distal two thirds of the renal artery and its branches.
What is "fibromuscular dysplasia"?
500
Carotid restenosis may occur following angioplasty and stenting. Narrowing of the stented segment is most frequently caused by this abnormality.
What is "neointimal hyperplasia"?
500
These are considered to be normal mean velocities for the MCA
What is "<120 cm/s"?
500
The brachiocephalic and subclavian veins are often not able to be assessed with compressions due to bony structures. Asking the patient to do this will alter the venous flow and may cause the venous lumen to briefly collapse, confirming lack of thrombus.
What is "sniff"?
500
A quality assurance program involves these activities (name at least 3 possible activities)
What are "quality control testing, preventive maintenance, in-service education of technologists, bid specification writing and bid response, acceptance testing of new equipment, and evaluation of new products"?
