Nitroprusside purpose CORRECT ANSWER decreases preload and afterload by vasodilation (mainly afterload) Dobutamine mechanism of action CORRECT ANSWER contractility Dopamine at a low-end dose "renal dose" CORRECT ANSWER 0.5-4mcg/kg/min increases renal and mesentric perfusion Dopamine at a mid-range dose CORRECT ANSWER 4-10mcg/kg/min increases contractility and heart rate Dopamine at a high-range dose CORRECT ANSWER greater than 10mcg/kg/min vasoconstriction and increases BP ...

Excitability correct answers the ability of non-pacemaker heart cells to respond to an electrical impulse that begins in pacemaker cells. Depolarization correct answers occurs when the normally negatively charged cells within the heart muscle develop a positive charge. Conductivity correct answers the ability to send an electrical stimulus from cell membrane to cell membrane. As a result, excitable cells depolarize in rapid succession from cell to cell until all cells have depolarized. Ex:...

A nurse is monitoring a client who has just returned to the unit following surgery. The client received an initial dose of morphine 5 mg IV bolus for pain relief. Which of the following adverse effects should the nurse report immediately to the provider?
