Nursing Care of Patients With Cardiac Dysrhythmias Multiple Choice Identify the choice that best completes the statement or answers the question. ____ 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? a. Atrial repolarization b. Atrial depolarization c. Ventricular repolarization d. Ventricular depolarization ____ 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? a. P wave b. Q wave c. R wave d. S wave ____ 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? a. Q wave b. R wave c. S wave d. T wave ____ 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? a. Q wave b. R wave c. S wave d. T wave ____ 5. A patient is experiencing electrocardiogram changes. Which wave should the nurse recognize as representing ventricular repolarization? a. Q wave b. R wave c. S wave d. T wave ____ 6. A patient is admitted for diagnosis of an electrocardiogram abnormality. Which wave should the nurse plan care based upon changes in the patient’s ventricular depolarization? a. P wave b. QRS complex c. U wave d. T wave ____ 7. After reviewing an electrocardiogram the nurse determines that an electrical impulse originated in a patient’s the sinoatrial node. What did the nurse see on this tracing? a. An upright T wave b. An inverted T wave c. A positive P wave before a QRS complex d. A negative P wave before a QRS complex ____ 8. The nurse is reinforcing teaching for a patient who has a pacemaker. Which measure should the nurse include when explaining how the pulse should be monitored? a. Take radial pulse for 1 minute. b. Take apical pulse for 1 minute. c. Take jugular pulse for 30 seconds. d. Take brachial pulse for 30 seconds. ____ 9. The nurse is teaching a patient what complications to report with a pacemaker rate set at 72 beats/minute. Which patient response indicates that further teaching is necessary? a. “A pulse of 74 is still considered sa MULTIPLE CHOICE 1. ANS: B P waves represent atrial depolarization. A. C. D. The P wave does not represent atrial repolarization, ventricular repolarization, or ventricular depolarization.

C. D. These are not the first positive waves in the cardiac cycle. PTS: 1 DIF: Moderate KEY: Client Need: Physiological Integrity—Reduction of Risk Potential | Cognitive Level: Application 3.
