Lewis's Medical-Surgical Nursing: Assessment and Management of Clinical Problems 11th Edition TEST BANK [ 211581]

A 74-yr-old patient has just arrived in the emergency department. After assessment reveals a pulse deficit of 46 beats, the nurse will anticipate that the patient may require a. emergent cardioversion. b. a cardiac catheterization. c. hourly blood pressure (BP) checks. d. electrocardiographic (ECG) monitoring. - -ANS: D Pulse deficit is a difference between simultaneously obtained apical and radial pulses. It indicates that there may be a cardiac dysrhythmia that would best be detected with ECG monitoring. Frequent BP monitoring, cardiac catheterization, and emergent cardioversion are used for diagnosis and/or treatment of cardiovascular disorders but would not be as helpful in determining the immediate reason for the pulse deficit. -The nurse is reviewing the 12-lead electrocardiograph (ECG) for a healthy 74-yr- old patient who is having an annual physical examination. What finding is of most concern to the nurse? a. A right bundle-branch block. c. The QRS duration is 0.13 seconds. b. The PR interval is 0.21 seconds. d. The heart rate (HR) is 41 beats/min. - -ANS: D The resting HR does not change with aging, so the decrease in HR requires further investigation. Bundle-branch block and slight increases in PR interval or QRS d
