Questions And Complete Answers.
Which nursing intervention must a nurse perform when administering prescribed vasopressors to a
client with a cardiac dysrhythmia? - Answer Monitor vital signs and cardiac rhythm
Which ECG waveform characterizes conduction of an electrical impulse through the left ventricle? -
Answer QRS complex
Which is not likely origination point for cardiac dysrhythmias? - Answer Bundle of His
The nurse is teaching a beginning EKG class to staff nurses. As the nurse begins to discuss the parts of the
EKG complex, one of the students asks what the normal order of conduction through the heart is. What
order does the nurse describe? - Answer Sinoatrial (SA) node, atrioventricular (AV) node, bundle of His,
right and left bundle branches, and the Purkinje fibers
A 28-year-old client presents to the emergency department, stating severe restlessness and anxiety.
Upon assessment, the client's heart rate is 118 bpm and regular, the client's pupils are dilated, and the
client appears excitable. Which action should the nurse take next? - Answer Question the client about
alcohol and illicit drug use.
A patient who had a myocardial infarction is experiencing severe chest pain and alerts the nurse. The
nurse begins the assessment but suddenly the patient becomes unresponsive, no pulse, with the
monitor showing a rapid, disorganized ventricular rhythm. What does the nurse interpret this rhythm to
be? - Answer ventricular fibrillation
A healthy adult client is seeing a health care provider for an annual physical examination. While the
nurse is taking the client's vital signs, the client states, "Occasionally, my heart skips a beat." The nurse
believes that the client is experiencing what condition? - Answer premature atrial complex (PAC)
A nursing instructor is reviewing the parts of an EKG strip with a group of students. One student asks
about the names of all the EKG cardiac complex parts. Which of the following items are considered a
part of the cardiac complex on an EKG strip? Choose all that apply. - Answer P-R Interval
P wave
,T wave
The nurse documents that a client is having a normal sinus rhythm. What characteristics of this rhythm
has the nurse assessed? - Answer The sinoatrial (SA) node initiates the impulse.
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? - Answer A defibrillator
The nurse is working on a monitored unit assessing the cardiac monitor rhythms. Which waveform
pattern needs attention first? - Answer ventricular fibrillation
***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 is monitored and reported to the physician but is not addressed first.
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? - Answer During ventricular
depolarization
A nurse is caring for a client with atrial fibrillation. What procedure would the nurse educate the patient
about for termination of the dysrhythmia? - Answer Elective cardioversion
***Pacemakers are implanted for Sinus Bradycardia.
When the nurse observes an electrocardiogram (ECG) tracing on a cardiac monitor with a pattern in lead
II and observes a bizarre, abnormal shape to the QRS complex, the nurse has likely observed which of
the following ventricular dysrhythmias? - Answer Premature ventricular contraction (PVC)
The nurse identifies which of the following as a potential cause of premature ventricular complexes
(PVCs)? - Answer hypokalemia
, ***PVCs can be caused by cardiac ischemia or infarction, increased workload on the heart (e.g., exercise,
fever, hypervolemia, heart failure, tachycardia), digitalis toxicity, acidosis, or electrolyte imbalances,
especially hypokalemia.
The nurse is caring for a client with atrial fibrillation. What procedure would be recommended if drug
therapies did not control the dysrhythmia? - Answer Elective cardioversion
A client with dilated cardiomyopathy is having frequent episodes of ventricular fibrillation. What medical
treatment does the nurse anticipate the client will have to terminate the episode of ventricular
fibrillation? - Answer internal cardioverter defibrillator insertion
The nurse is placing electrodes for a 12-lead electrocardiogram (ECG). The nurse would be correct in
placing an electrode on which area for V1? - Answer Right side of sternum, fourth intercostal space
The nurse knows that electrocardiogram (ECG) characteristics of atrial fibrillation include what? - Answer
Atrial rate of 300 to 400
The nurse is admitting a client to a telemetry unit with an atrial dysrhythmia. What symptoms will the
nurse further evaluate? - Answer chest pain
A client has an irregular heart rate of around 100 beats/minute and a significant pulse deficit. What
component of the client's history would produce such symptoms? - Answer atrial fibrillation
The nurse analyzes the electrocardiogram (ECG) tracing of a client newly admitted to the cardiac step-
down unit with a diagnosis of chest pain. Which finding indicates the need for follow-up? - Answer QT
interval that is 0. 46 seconds long
Which electrocardiogram (ECG) characteristic is usually seen when a client's serum potassium level is
low? - Answer u wave
The nurse is attempting to determine the ventricular rate and rhythm of a patient's telemetry strip. What
should the nurse examine to determine this part of the analysis? - Answer RR interval
