CIL& blood - diagnostic terms not built from word parts

Question 1

digital subtraction angiography (DSA)

Answer 1

process of digital radiographic imaging of the blood vessels that “subtracts” or removes structures not being studied

Question 2

doppler ultrasound

Answer 2

study that uses high-frequency sound waves for detection of blood flow within the vessels; used to assess intermittent claudication, deep vein thrombosis, and other blood flow abnormalities.

Question 3

sestamibi test

Answer 3

nuclear medicine test used to diagnose coronary artery disease and assess revascularization after coronary artery bypass surgery. Sestamibi, a radioactive isotope, is taken up by normal myocardial cells, but not in ischemia or infarction. These areas are identified as “cold” spots on the images produced.

Question 4

single-photon emission computed tomography (SPECT)

Answer 4

nuclear medicine scan that visualizes the heart from several different angles, producing three-dimensional images; used to asses damage to cardiac tissue

Question 5

transesophageal echocardiogram (TEE)

Answer 5

ultrasound test that examines cardiac function and structure by using an ultrasound probe placed in the esophagus, which provides more direct views of the heart structures.

Question 6

cardiac catheterization

Answer 6

diagnostic procedure performed by passing a catheter into the heart from a blood vessel in the groin or arm to examine the condition of the heart and surrounding blood vessels; used to diagnose and treat cardiovascular condition such as coronary artery disease.

Question 7

exercise stress test

Answer 7

study that evaluates cardiac function during physical stress by riding a bike or walking on a treadmill. Electrocardiography is the most common method, but echocardiography, and nuclear medicine scanning (diagnostic imaging tests) can also be used to measure cardiac function while exercising.

Question 8

blood pressure (BP)

Answer 8

pressure exerted by the blood against the blood vessel walls. A blood pressure measurement written as systolic pressure (120) and diastolic pressure (80) is commonly recorded as 120/80

Question 9

pulse

Answer 9

contraction of the heart, which can be felt with a fingertip. The pulse is most commonly felt over the radial artery (in the wrist)

Question 10

sphygmomanometer

Answer 10

device used for measuring blood pressure

Question 11

C-reactive protein (CRP)

Answer 11

blood test to measure the amount of C-reactive protein in the blood, which when elevated, indicates inflammation in the body. It is sometimes used in assessing the risk of cardiovascular disease.

Question 12

creatine phosphokinase (CPK)

Answer 12

blood test used to measure the level of creatine phosphokinase, an enzyme of heart and skeletal muscle released into the blood after muscle injury or necrosis. The test is useful in evaluating patients with acute myocardial infarction.

Question 13

lipid profile

Answer 13

blood test used to measure the amount and type of lips (fat-like substances) in a sample of blood. This test is used to evaluate one of the risks of cardiovascular disease, and to monitor therapy for patients taking lipid-lowering medications.

Question 14

troponin

Answer 14

blood test that measures troponin, a heart muscle enzyme. Troponins are released into the blood approximately 3 hours after necrosis of the heart muscle and may remain elevated from 7 to 10 days. The test is useful in the diagnosis of a myocardial infarction.

Question 15

activated partial thromboplastin time (aPTT)

Answer 15

blood test used to monitor anticoagulation therapy for patients taking heparin, an intravenous anticoagulant medication.

Question 16

coagulation time

Answer 16

blood test to determine the time it takes for blood to form a clot.

Question 17

complete blood count (CBC) and differential (Diff)

Answer 17

laboratory test for basic blood screening that measures various aspects of erythrocytes, leukocytes, and thrombocytes (platelets); this automated test quickly provides a tremendous amount of information about the blood.

Question 18

hematocrit (Hct)

Answer 18

percentage of a blood sample that is composed of erythrocytes. It is used in the diagnosis and evaluation of anemic patients.

Question 19

hemoglobin (Hgb)

Answer 19

blood test that measures the amount of hemoglobin (the protein in red blood cells that carries oxygen) in the blood.

Question 20

prothrombin time (PT)

Answer 20

blood test used to determine certain coagulation activity defects and to monitor anticoagulation therapy for patients taking warfarin, an oral anticoagulant medication.
