The nurse is caring for a patient admitted with cardiogenic shock.Hemodynamic readings obtained with a pulmonary artery catheter include a pulmonary artery occlusion pressure (PAOP)of 18 mm Hg and a cardiac index (CI)of 1.0 L/min/m².What is the priority pharmacological intervention?
A) Dobutamine (Dobutrex)
B) Furosemide (Lasix)
C) Phenylephrine (Neo-Synephrine)
D) Sodium nitroprusside (Nipride)

Positive inotropic agents (e.g.,dobutamine)are given to increase the contractile force of the heart.As contractility increases,cardiac output and index increase and improve tissue perfusion.Administration of furosemide will assist only in managing fluid volume overload.Phenylephrine administration enhances vasoconstriction,which may increase afterload and further reduce cardiac output.Sodium nitroprusside is given to reduce afterload.There is no evidence to support a need for afterload reduction in this scenario.
