MOCK EXAM (WITH145Q&A)SOCIAL PSYCHOLOGY (1ST YEAR INTERNATIONAL PSYCHOLOGY BA) f a renal artery Doppler exam demonstrates stenosis but normal flow is identified on angiography evaluation, the US results are described as: false positive When a clot is present on a venogram, how does it appear on the image? "empty" vein with no contrast opacification The Doppler tracing demonstrates electrical noise. How can you reduce or eliminate the artifact? Increase the wall filter settings What explains why a patient can receive an US diagnosis of 70% IC A stenosis, but an angiography diagnosis of 50% ICA stenosis? Angiography only evaluates the longitudinal axis of the vessel which can lead to over - or under -estimation of the stenosis What can cause an increase in the resistive index (RI) of the distal common carotid artery? proximal ICA stenosis What correctly describes the positive predictive value (PPV) of a testing technique? If the test result is positive, PPV is the probability that the patient actually has disease What is the gold standard method of diagnosing temporal arteritis? biopsy This image demonstrates what? Peripheral edema What is caus e the waveform displayed? arrhythmia Bilateral homonymous hemi anopia is most commonly seen with: vertebrobasilar disease - unilateral visual symptoms are most commonly related What describes chronic lower extremity DVT echogenic vein walls __________ refers to a collection of mucinous material within the adventitial wall layer of the affected vessel adventitial cyst What would cause flow in the left ECA to reverse direction during systole? left CCA occlusion What is a congenital vascular abnormality that commonly causes decreased ankle pressures bilaterally? Coarctation of the aorta What cardiac abnormality usually has No effect on the peak systolic velocities in the carotid arteries? mitral valve regurgitation What describes collateral flow from the ECA tot eh ICA on the same side of the body? superficial temporal artery to the ophth almic artery Unilateral swelling of the lower extremity would be an expected clinical finding with: Left popliteal DVT - bilateral swelling is associated with renal disease, CHF, and IVC thrombosis A patient presents with gangrene of the foot and toes. Th e most likely cause of these symptoms is: extensive deep and superficial vein thrombosis Where should the second caliper be placed to measure the acceleration time of the renal artery? When evaluating the Doppler waveform at a focal stenosis in the proximal ICA, which of the following Doppler characteristics will be demonstrated? increased peak systolic velocity, increased end diastolic velocityThe benefits of buying summaries with Stuvia:
