____     1.   A patient is diagnosed with a disorder affecting the P wave within the cardiac cycle. The nurse should plan care to address which cardiac action?

____     2.   The nurse is reviewing a patient’s electrocardiogram. Which wave should the nurse recognize as being the first positive wave in a normal cardiac cycle?

____     3.   A patient is having an electrocardiogram. Which wave should the nurse identify as being the first negative wave after a P wave in a normal cardiac cycle?

____     4.   The nurse is reviewing a patient’s electrocardiogram. Which wave should the nurse identify as being the second positive wave in a normal cardiac cycle?

____     5.   A patient is experiencing electrocardiogram changes. Which wave should the nurse recognize as representing ventricular repolarization?
