Chapter 26 : Caring for Clients With Cardiac Arrhythmias Questions
Question 1 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.
Question 2 of 5
The nurse is instructing on home care after placement of an implanted cardioverter defibrillator (ICD). Which statement, made by the client, needs clarification by the nurse?
Correct Answer: C
Rationale: Similar to hand tools, microwaves have shields or are grounded, making them safe for clients with ICDs. There is no restriction from microwave use. All of the other options are correct.
Question 3 of 5
Which of the following does the nurse recognize as the therapeutic goal of radiofrequency catheter ablation for a client with cardiac arrhythmias?
Correct Answer: C
Rationale: The therapeutic goal of radiofrequency catheter ablation is to destroy errant tissue, in hopes of allowing impulse conduction to travel over appropriate pathways. The goal does not include dilation of blood vessels or reperfusion of heart tissue. There is no stimulation of the heart.
Question 4 of 5
The nurse is preparing to defibrillate a client with no breathing or pulse. Which nursing action precedes the nurse pressing the discharge button?
Correct Answer: C
Rationale: Preceding pressing the discharge button, the nurse shouts 'All clear' to ensure that no one is in contact with the client. The other options are correct but not the nursing action immediately preceding.
Question 5 of 5
The nurse is working on a monitored unit assessing the cardiac monitor rhythms. Which waveform pattern needs attention first?
Correct Answer: D
Rationale: Ventricular fibrillation is called the rhythm of a dying heart. It is the rhythm that needs attention first because there is no cardiac output, and it is an indication for CPR and immediate defibrillation. Sustained asystole either is from death, or the client is off of the cardiac monitor. Supraventricular tachycardia and atrial fibrillation are monitored and reported to the physician but not addressed first.
