Chapter 26 : Caring for Clients With Cardiac Arrhythmias Questions
Question 1 of 5
The licensed practical nurse is monitoring the waveform pattern on the cardiac monitor of the client admitted following a myocardial infarction. The nurse notes that every other beat includes a premature ventricular contraction (PVC). The nurse notes which of the following in the permanent record?
Correct Answer: A
Rationale: The nurse is correct to note bigeminy on the permanent record when every other beat is a PVC. Couplets are two PVCs in a row. Multifocal PVCs originate from more than one location. R-on-T phenomenon occurs when the R wave falls on the T wave.
Question 2 of 5
Which of the following medications does the nurse anticipate administering to a client preparing for cardioversion?
Correct Answer: D
Rationale: Prior to cardioversion, cardiac medications are held, and the client is sedated with a medication such as diazepam.
Question 3 of 5
For which client does the nurse anticipate cardioversion as a possible medical treatment?
Correct Answer: D
Rationale: The nurse is correct to identify a client with atrial arrhythmias as a candidate for cardioversion. The goal of cardioversion is to restore the normal pacemaker of the heart, as well as normal conduction. A client with a myocardial infarction has tissue damage. The client with poor perfusion has circulation problems. The client with heart block has an impairment in the conduction system and may require a pacemaker.
Question 4 of 5
The licensed practical nurse is setting up the room for a client arriving at the emergency department with ventricular arrhythmias. The nurse is most correct to place which of the following in the room for treatment?
Correct Answer: B
Rationale: The nurse is most correct to place a defibrillator close to the client room if not in the room. The nurse realizes that clients with ventricular arrhythmias are at a high risk for fatal heart arrhythmia and death. A suction machine is used to remove respiratory secretions. Cardioversion is used in a planned setting for atrial arrhythmias. An ECG machine records tracings of the heart for diagnostic purposes. Most clients with history of cardiac disorders have an ECG completed.
Question 5 of 5
The nurse is providing instruction to a group of new nurses orienting on the unit, highlighting the benefits of the implantable cardioverter defibrillator (ICD). While pointing at a diagram of the heart, at which location would the nurse identify the placement of the electrical lead?
Correct Answer: B
Rationale: The nurse is correct to explain that an ICD consists of a generator with a battery and one or two electrical leads that resemble a wire. The generator is placed under the skin, and the lead wire is inserted transvenously through the subclavian or cephalic vein to the apex or septum of the right ventricle. The other options are incorrect.
