1What are signs of heart failure?
progressive, often fatal disorder
fluid retention = in lungs so causes trouble breathing
2Patho of heart failure
inadequate tissue perfusion = circulation issues
volume overload
dysrhythmias = common with heart failure
aging of the myocardium = typical in elderly
3Which two categories would be the worst classification of heart disease?
AHA = Category D
NYHA = IV
4Why do patients with heart failure need a diuretic?
they are retaining fluid = edema
they have fluid in the lungs = crackles
5Dopamine
catecholamine
drip to help regulate
helps cardiac status
6Digoxin positive inotropic action
increase myocardial contractile force = can help heart to beat better IF you can take them
alter electrical activity of the heart
favorably affect neurohormonal systems
Second-line agents
7Digoxin
naturally occurring compound
profound effects on the mechanical and electrical properties of the heart
adverse: can cause severe dysrhythmias, narrow therapeutic range 0.5-0.8mg/mL
potassium levels must be kept in normal physiologic range
half life about 1.5 days = strong drug that stays in your system
8Toxicity or OD Digoxin
N,V and visual effects (will see halos around objects)
if heart rate is <60, notify provider, hold drug
if they have dysrhythmias = listen to heart at apical point
