(14e): Management of Patients with
Dysrhythmias and Conduction Problems
Terms in this set (40)
1). The nurse is caring for a patient who has had an ECG. The nurse notes that leads I, II, and III
differ from one another on the cardiac rhythm strip. How should the nurse best respond?
A) Recognize the view of the electrical current changes in relation to the lead placement.
B) Recognize the electrophysiological conduction of the heart differs with lead placement.
C) Inform the technician that the ECG has malfunctioned
D) Inform physician patient is experiencing a new onset of dysrhythmia
A) Recognize the view of the electrical current changes in relation to the lead placement.
%
Feedback:
Each lead offers a different reference point to view the electrical activity of the heart. The lead
displays the configuration of electrical activity of the heart. Differences between leads are not
necessarily attributed to equipment malfunction or dysrhythmias.

2). The nurse is analyzing a rhythm strip. What component of the ECG corresponds to the resting
state of the patient's heart?
A) P wave
B) T wave
C) U wave
D) QRS complex
B) T wave
Feedback:
The T wave specifically represents ventricular muscle depolarization, also referred to as the resting
state. Ventricular muscle depolarization does not result in the P wave, U wave, or QRS complex.

3). The nursing educator is presenting a case study of an adult patient who has abnormal ventricular
depolarization. This pathologic change would be most evident in what component of the ECG?
A) P wave
B) T wave
C) QRS complex
D) U wave
C) QRS complex
Feedback:
The QRS complex represents the depolarization of the ventricles and, as such, the electrical activity
of that ventricle.
3 multiple choice options
4). An adult patient with third-degree AV block is admitted to the cardiac care unit and placed on
continuous cardiac monitoring. What rhythm characteristic will the ECG most likely show?
A) PP interval and RR interval are irregular.
B) PP interval is equal to RR interval.
C) Fewer QRS complexes than P waves
D) PR interval is constant.
%
C) Fewer QRS complexes than P waves
Feedback:
In third-degree AV block, no atrial impulse is conducted through the AV node into the ventricles. As a
result, there are impulses stimulating the atria and impulses stimulating the ventricles. Therefore,
there are more P waves than QRS complexes due to the difference in the natural pacemaker (nodes)
rates of the heart. The other listed ECG changes are not consistent with this diagnosis.

5). The nurse is writing a plan of care for a patient with a cardiac dysrhythmia. What would be the
most appropriate goal for the patient?
A) Maintain a resting heart rate below 70 bpm.
B) Maintain adequate control of chest pain.
C) Maintain adequate cardiac output.
D) Maintain normal cardiac structure.
C) Maintain adequate cardiac output.
Feedback:
stuvia
, STUVIA 2024/2025
For patient safety, the most appropriate goal is to maintain cardiac output to prevent worsening
complications as a result of decreased cardiac output. A resting rate of less than 70 bpm is not
appropriate for every patient. Chest pain is more closely associated with acute coronary syndrome
than with dysrhythmias. Nursing actions cannot normally influence the physical structure of the heart.

6). A patient has returned to the cardiac care unit after having a permanent pacemaker implantation.
For which potential complication should the nurse most closely assess this patient?
A) Chest pain
B) Bleeding at the implantation site
C) Malignant hyperthermia
D) Bradycardia
B) Bleeding at the implantation site
Feedback:
Bleeding, hematomas, local infections, perforation of the myocardium, and tachycardia are
complications of pacemaker implantations. The nurse should monitor for chest pain and bradycardia,
but bleeding is a more common immediate complication. Malignant hyperthermia is unlikely because
it is a response to anesthesia administration.

7). A patient the nurse is caring for has a permanent pacemaker implanted with the identification code
beginning with VVI. What does this indicate?
A) Ventricular paced, ventricular sensed, inhibited
B) Variable paced, ventricular sensed, inhibited
C) Ventricular sensed, ventricular situated, implanted
D) Variable sensed, variable paced, inhibited
A) Ventricular paced, ventricular sensed, inhibited
Feedback:
The identification of VVI indicates ventricular paced, ventricular sensed, inhibited.
3 multiple choice options
8). The nurse is caring for an adult patient who has gone into ventricular fibrillation. When assisting
with defibrillating the patient, what must the nurse do?
A) Maintain firm contact between paddles and patient skin.
B) Apply a layer of water as a conducting agent.
C) Call "all clear" once before discharging the defibrillator.
D) Ensure the defibrillator is in the sync mode.
A) Maintain firm contact between paddles and patient skin.
