define LEUKEMIA
cancer w/progressive increase in abnormal WBC in blood-forming tissues, organs, & blood
define APLASTIC ANEMIA
no formed elements (leukopenia & thrombocytopenia)
describe IRON DEFICIENCY ANEMIA
most common; not enough iron to make hemoglobin
cause: iron-deficiency anemia
blood loss, poor iron absorption, inadequate iron intake
describe MEGALOBLASTIC ANEMIA
blood disorder w/symptom of anemia; RBCs bigger than normal
cause: megaloblastic anemia
deficiency of folic acid/vitamin B12

describe MEGALOBLASTIC ANEMIA | blood disorder w/symptom of anemia; RBCs bigger than normal |
cause: megaloblastic anemia | deficiency of folic acid/vitamin B12 |
describe PERNICIOUS ANEMIA | lack protein intrinsic factor to absorb vitamin B12 --> vitamin B12 deficiency |
define HEMOLYTIC ANEMIA | inherited/acquired; not enough RBCs bc spleen destroying them too early |
describe SICKLE CELL ANEMIA | inherited & recessive; RBCs malformed after giving up O2 --> lose flexibility & surface area for gas exchange |
describe THALASSEMIA | inherited & common around Mediterrarian; mild/severe from low hemoglobin & RBCs |
thalassemia is also called | Cooley's anemia |
define ORTHOSTATIC HYPOTENSION | hypotension when standing |
orthostatic hypotension is also called | postural hypotension |
define FLUTTER/ATRIAL FLUTTER | atria beats faster than ventricles --> quivering |
define PREMATURE VENTRICULAR CONTRACTIONS | extra, abnormal heartbeats that disrupt regular ventricular rhythm |
define CARDIAC TAMPONADE | excess fluid in pericardium |
define EDEMATOUS | swelling often associated w/insufficient function of LV |
s/s: shock | agitation, anxiety, restlessness, confusion, cool/pale/clammy skin, cyanosis, chest pain, dizziness, lightheadedness |
define SHOCK | peripheral blood flow insufficient to return to heart |
define ANGIOGRAPHY | x-ray of blood vessels w/contrast |
describe CARDIAC CATHETERIZATION (card cath/CC) | diagnostic & treatment; catheter in vein/artery to heart for angiographies, angioplasties, pressure readings, or take samples |
define DUPLEX ULTRASOUND | capture blood vessels & flow of blood |
define VENOGRAPHY | shows specific veins w/contrast |
define ELECTROCARDIOGRAPHY (EKG/ECG) | records electrical activity of myocardium |
define HOLTER MONITOR | portable ECG on ambulatory patient over 24-48 hr period to diagnose arrhythmia |
define STRESS TEST | see cardiovascular health & function while on treadmill/injected with meds to increase bpm |
define THALLIUM STRESS TEST | how well blood flows thru coronary arteries during exercise |
describe DOPPLER SONOGRAPHY/DOPPLER ULTRASOUND | measure blood flow & BP; sound waves bounce off RBCs |
define ECHOCARDIOGRAM | ultrasound visualize internal structure |
echocardiogram is also called | multigated acquisition (MUGA) scan |
define APHERESIS | separate blood into components to remove toxic substances/autoantibodies or harvest blood cells |
define COMPLETE BLOOD COUNT | determine # of formed elements including hematocrit & WBC differential |
define TYPE & CROSSMATCH | check blood type compatibility |
define NUCLEAR VENTRICULOGRAPHY | tracer injected to make images of LV & RV to measure volume of blood pumped by ventricles |
define POSITION EMISSION TOMOGRAPHY SCAN | tracer look for disease/poor blood flow in heart or brain |
what can diagnose heart damage, scar tissue, CVA, Alzheimer's & epilepsy | PET scan |
define ANTIPHYPERTENSIVE | lower BP |
define ACE INHIBITOR | blocks action of angiotensin II contracting blood vessel to treat hypertension & heart failure |
ACE inhibitor is also known as | angiotensin-converting enzyme |
describe BETA BLOCKER | decrease workload of heart by slowing bpm; treats hypertension, angina, heart failure, heart rhythm disorders, migraines, panic attacks, & tremors |
