Nokea
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.
- A. Transatrial
- B. Transcutaneous
- C. Transvenous
- D. Transthoracic
- E. Transabdominal
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.

The nurse is caring for a client who has premature ventricular contractions. What sign or symptom is observed in this client?
- A. Fluttering
- B. Nausea
- C. Hypotension
- D. Fever
Correct Answer: A
Rationale: Premature ventricular contractions usually cause a flip-flop sensation in the chest, sometimes described as 'fluttering.' Associated signs and symptoms include pallor, nervousness, sweating, and faintness. Symptoms of premature ventricular contractions are not nausea, hypotension, and fever.
The nurse is preparing to defibrillate a client with no breathing or pulse. Which nursing action precedes the nurse pressing the discharge button?
- A. Placing gel on the chest
- B. Checking the ECG rhythm
- C. Shouting, 'All clear'
- D. Stating, 'Charging'
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.
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?
- A. Bigeminy
- B. Couplets
- C. Multifocal PVCs
- D. R-on-T phenomenon
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.
Elective cardioversion is similar to defibrillation except that the electrical stimulation waits to discharge until an R wave appears. What does this prevent?
- A. Disrupting the heart during the critical period of atrial repolarization
- B. Disrupting the heart during the critical period of ventricular repolarization
- C. Disrupting the heart during the critical period of ventricular depolarization
- D. Disrupting the heart during the critical period of atrial depolarization
Correct Answer: B
Rationale: It is similar to defibrillation. One difference is that the machine that delivers the electrical stimulation waits to discharge until it senses the appearance of an R wave. By doing so, the machine prevents disrupting the heart during the critical period of ventricular repolarization.
The staff educator is teaching a class in arrhythmias. What statement is correct for defibrillation?
- A. It is a scheduled procedure 1 to 10 days in advance.
- B. The client is sedated before the procedure.
- C. It is used to eliminate ventricular arrhythmias.
- D. It uses less electrical energy than cardioversion.
Correct Answer: C
Rationale: The only treatment for a life-threatening ventricular arrhythmia is immediate defibrillation, which has the exact same effect as cardioversion, except that defibrillation is used when there is no functional ventricular contraction. It is an emergency procedure performed during resuscitation. The client is not sedated but is unresponsive. Defibrillation uses more electrical energy (200 to 360 joules) than cardioversion.
