Chapter 26 : Caring for Clients With Cardiac Arrhythmias Questions
Question 1 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.
Question 2 of 5
Which diagnostic study best evaluates different medications' ability to restore normal heart rhythm?
Correct Answer: C
Rationale: An electrophysiology study is a procedure that enables the physician to examine the electrical activity of the heart, produce actual arrhythmias, and determine the best method for care. Cardioversion uses synchronized electricity to change the rhythm pattern. Electrocardiogram and echocardiograms provide diagnostic information.
Question 3 of 5
The nurse and student nurse are observing a cardioversion procedure. The nurse is correct to tell the student that electrical current will be initiated at which time?
Correct Answer: C
Rationale: The electrical current is initiated at the R wave when ventricular depolarization occurs. The electrical current completely depolarizes the entire myocardium with the goal of restoring the normal pacemaker of the heart.
Question 4 of 5
The client has just been admitted with bradycardia and scheduled for the insertion of a pacemaker. The nurse notifies the physician that the client's heart rate has dropped into the 40 beats/minute range. The physician orders a temporary pacemaker. The nurse knows that there are different types of temporary pacemakers. What types of temporary pacemakers are there? Select all that apply.
Correct Answer: B,C,D
Rationale: The three types of temporary pacemakers are transcutaneous, transvenous, and transthoracic. Transatrial and transabdominal are not types of temporary pacemakers.
Question 5 of 5
The nurse reports to the cardiac nurse practitioner that the client is consistently exhibiting a normal sinus rhythm. What characteristic(s) has the nurse noted to determine the rhythm is normal? Select all that apply.
Correct Answer: B,C,E,F
Rationale: Characteristics of normal sinus rhythm include a regular impulse originating in the SA node and with impulses continuing to the AV node. There is a P wave initially with depolarization at the QRS complex and ending with a T wave. Normal heart rate is between 60 to 100 beats/minute.
