Document Summary
Questions: what should the nurse recognize as an indication for the use of dopamine in the care of a patient with heart failure, acute anxiety, hypotension and tachycardia, peripheral edema and weight gain, paroxysmal nocturnal dyspnea (pnd) Dopamine is a -adrenergic agonist whose inotropic action is used for treatment of severe heart failure accompanied by hemodynamic instability. Such a state may be indicated by tachycardia accompanied by hypotension. Pnd, anxiety, edema, and weight gain are common signs and symptoms of heart failure, but these do not necessarily warrant the use of dopamine: a patient with a recent diagnosis of heart failure has been prescribed furosemide (lasix). What outcome does the nurse anticipate will occur that demonstrates medication effectiveness: promote vasodilation, reduction of preload, decrease in afterload, increase in contractility. Diuretics such as furosemide are used in the treatment of heart failure to mobilize edematous fluid, reduce pulmonary venous pressure, and reduce preload.
