Primary malignant tumor

,correct answer: lack of organization of cells.
glucocorticoids
correct answer: used in combination with other agent to treat lymphoid
tissue (leukemia). glucocorticoids are directly toxic to lymphoid tissues.

Heart failure
correct answer: impairment of the ventricle to fill with or eject blood; heart
cannot meet metabolic need of the body.
CHF
correct answer: heart cannot keep up with metabolic needs; volume
overload in pulmonary area.
Left Ventricular Dysfunction
correct answer: reduced ejection fraction; ventricle having issue ejecting
blood.
normal ejection fraction
correct answer: 55 - 60 % (blood pumped out with each heartbeat).
Ejection fraction of 50% - reduced or preserved?
Correct answer: preserved.
Diastolic CHF
correct answer: preserved ejection fraction, problem is with filling.
Systolic CHF
correct answer: reduced ejection fraction, problem is with ejecting.
Left sided CHF
correct answer: pulmonary (JVD, fluid volume overload, rails, S-3 murmurs)
** #1 cause of Right sided CHF.
BNP
correct answer: gold standard lab test to diagnose CHF.

patients using cardiotoxins with family history.

metabolic syndrome.
Meds: ACEI or Angiotensin II RB for vascular disease or
diabetes (avapro, losartan, benicar, diovan, etc).

HF.

fatigue, reduced exercise tolerance.
Therapy for Stage C HF
correct answer: dietary salt restriction, MEDS: diuretic, ACEI, beta blockers.
Some patients: aldosterone antagonist, ARBs, digitalis, hydralazine/nitrates,
biventricular pacing, implantable defibrillators.
