A patient is admitted to the critical care unit with the diagnosis of cardiogenic shock. The nurse knows the initial management procedure of a patient with cardiogenic shock and is aware that which of the following medications is not given?
A) Norepinephrine (Levophed)
B) Furosemide(Lasix)
C) Dobutamine (Dobutrex)
D) Nitroprusside (Nipride)
Ans: A
Feedback: Medication therapy is selected and guided according to cardiac output, other cardiac parameters, and mean arterial pressure. Diuretics such as furosemide (Lasix) may be administered to decrease preload and afterload, reducing the workload of the heart. Vasodilators such as nitroprusside (Nipride) may be administered to reduce the volume returning to the heart, decrease blood pressure, and decrease cardiac workload. Positive inotropic medications such as dobutamine (Dobutrex) are administered to increase myocardial contractility. Vasopressors such as norepinephrine (Levophed) are not administered in the early stages of cardiogenic shock, as this medication classification tends to increase oxygen demands. Vasopressors are used to increase blood pressure and increase cardiac output and may be used after the initial stages of cardiogenic shock are managed.
