NUR 376 Exam #2 questions with
verified answers
Which nursing intervention must a nurse perform when
administering prescribed vasopressors to a client with a
cardiac dysrhythmia? - CORRECT ANSWERS ✔✔Monitor
vital signs and cardiac rhythm
Which ECG waveform characterizes conduction of an
electrical impulse through the left ventricle? - CORRECT
ANSWERS ✔✔QRS complex
Which is not likely origination point for cardiac
dysrhythmias? - CORRECT ANSWERS ✔✔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? - CORRECT ANSWERS ✔✔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? - CORRECT ANSWERS ✔✔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? - CORRECT ANSWERS
✔✔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? - CORRECT ANSWERS
✔✔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. -
CORRECT ANSWERS ✔✔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? - CORRECT ANSWERS ✔✔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? -
CORRECT ANSWERS ✔✔A defibrillator
The nurse is working on a monitored unit assessing the
cardiac monitor rhythms. Which waveform pattern needs
attention first? - CORRECT ANSWERS ✔✔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? - CORRECT ANSWERS ✔✔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? - CORRECT ANSWERS
✔✔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? - CORRECT ANSWERS
✔✔Premature ventricular contraction (PVC)
The nurse identifies which of the following as a potential
cause of premature ventricular complexes (PVCs)? -
CORRECT ANSWERS ✔✔hypokalemia
