Electrocardiography and Dysrhythmia Monitoring
1. A nurse is assisting with the care of a group of clients. The nurse should recognize which
of the following clients as being at risk for the development of a dysrhythmia? (Select all that
apply.)
A. A client who has metabolic alkalosis.
B. A client who has a blood potassium level of 4.3 mEq/L.
C. A client who has an SaO2 of 96%.
D. A client who has alcohol use disorder.
E. A client who underwent stent placement in a coronary artery.
answer: A client who has metabolic alkalosis.
A client who has an acid-base imbalance (metabolic alkalosis) is at risk for a dysrhythmia.
A client who has alcohol use disorder.
A client who has substance use disorder (alcohol or opioids) is at risk for dysrhythmias.
A client who underwent stent placement in a coronary artery.
A client who has cardiac disease and underwent a stent placement is at risk for a dysrhythmia.
A blood potassium of 4.3 mEq/L is within the expected reference range and does not increase the
risk of a dysrhythmia.

SaO2 of 96% is within the expected reference range and does not increase the risk of a
dysrhythmia.
2. A nurse is caring for a client who experienced defibrillation. Which of the following should
be included in the documentation of this procedure? (Select all that apply.)
A. Follow-up ECG.
B. Energy settings used.
C. IV fluid intake.
D. Urinary output.
E. Skin condition under electrodes.
answer: Follow-up ECG.
The client’s ECG rhythm is documented following the procedure.
Energy settings used.
Energy settings used during the procedure are documented.
Skin condition under electrodes.
The condition of the client’s skin where electrodes were placed is documented.
IV fluid intake is not documented during defibrillation.
Urinary output is not documented during defibrillation.

3. A nurse is caring for a client who is on telemetry. The nurse recognizes the client’s heart
rate is 46/min and notifies the provider. Which of the following prescriptions might be
appropriate for this client?
A. Defibrillation.
B. Pacemaker insertion.
C. Synchronized cardioversion.
D. Administration of IV lidocaine.
answer: Pacemaker insertion.
A client who has bradycardia is a candidate for a pacemaker to increase his heart rate.
Defibrillation is used when a client has ventricular fibrillation or pulseless ventricular
tachycardia.
Synchronized cardioversion is used when a client has a dysrhythmia such as atrial fibrillation,
supraventricular tachycardia (SVT), or ventricular tachycardia with pulse.
The administration of IV lidocaine is used in clients who have a pulseless ventricular
dysrhythmia to stimulate cardiac electrical function.
4. A nurse is reinforcing teaching with a client who is scheduled for synchronized
cardioversion for treatment of atrial fibrillation. The client asks why it is necessary that an
anticoagulant be taken for several weeks prior to the procedure. Which of the following
responses should the nurse make?

A. “The medication will improve the effectiveness of the cardioversion.”
B. “The medication may cause the heart to resume a normal rhythm so the procedure wouldn’t
be necessary.”
C. “The medication will prevent infection.”
D. “The medication will decrease the risk of blood clots causing further complications.”
answer: “The medication will decrease the risk of blood clots causing further
complications.”
Clients who have atrial fibrillation are at increased risk for the development of thrombus. The
use of an anticoagulant decreases the blood clotting ability and the risk of a thromboembolism
occurring during cardioversion.
Cardioversion is used to treat dysrhythmias by passing an electric current through the heart
which depolarizes all the heart cells at the same time, allowing a normal heart rhythm to resume.
Anticoagulant medications do not any effect on the effectiveness of the procedure.
Antidysrhythmic medications (procainamide) can allow the heard to resume a normal rhythm
because it slows the sodium channel and prolongs the time of depolarization while increasing the
refractory period.
Antibiotic medications (cefuroxime) can be administered prophylactically to prevent an infection
from occurring if a client is undergoing an invasive procedure.
