Chapter 22 Management of Patients With Arrhythmias and Conduction Problems1.A group of new nurses are going to work on the telemetry unit. They are taking a class on
electrocardiograms (ECGs) and arrhythmias. What would the staff educator tell this class about ST
segments?
A) The part of an ECG that reflects repolarization of the ventricles
B) The part of an ECG used to calculate ventricular rate and rhythm
C) The part of an ECG that reflects the time from ventricular depolarization through repolarization
D) The part of an ECG that reflects the end of the QRS complex to the beginning of the
T wave
2.A patient is undergoing preoperative teaching before cardiac surgery. The nurse explains that a
temporary pacemaker will be placed later that day, and it will be removed after the surgery. The
patient asks the nurse what will happen if the pacemaker quits functioning. What is the nurse's
best response?
A) “Monitoring for pacemaker malfunctioning and battery failure is something the nurse caring for you
does.”
B) “Monitoring for pacemaker malfunctioning and battery failure is something the technician down
the hall does.”
C) “Monitoring for pacemaker malfunctioning and battery failure is something the secretary at the
nurse's station does.”
D) “Monitoring for pacemaker malfunctioning and battery failure is something the health care provider
caring for you does when he makes rounds every day.”
3.The staff educator is teaching a CPR class. What is an important aspect of defibrillating that the
educator stresses to their class?
A) Use a conducting sheet between the paddles and the skin.
B) Use a conducting medium between the multifunction paddles and the skin. C)
Always use a squeeze-on gel between the paddles and the skin.
D) You can use any gel or paste between the paddles and the skin.
, 4.While teaching a CPR class, a student in the class asks what the difference is between cardioversion
and defibrillation. What would be the nurse's best response?
A) “Cardioversion is done on a beating heart; defibrillation is not.”
B) “The difference is the timing of the delivery of the electric current.”
C) “Defibrillation is synchronized with the electrical activity of the heart; cardioversion is not.”
D) “Cardioversion is always attempted before defibrillation because it is not as dangerous.”
5.A patient has been admitted to the unit for an electrophysiology (EP) study. For what is an
electrophysiology study primarily performed?
A) To facilitate cardioversion
B) To freeze hypersensitive cells
C) To diagnose the dysrhythmia
D) To determine the nursing plan of care
6.The nurse is analyzing a rhythm strip. What does the nurse look at to identify ventricular
repolarization?
A) P wave B) T wave C) U wave
D) QRS complex
7.A patient has returned from the operating room after having a permanent pacemaker
implantation. What potential complication should the nurse assess for most closely in a
postoperative patient immediately following permanent pacemaker implantation?
A) Decreased urinary output
B) Bleeding at the implantation site
C) Decreased respiratory rate
D) Deep venous thrombosis (DVT)
