nur 390 exam 2
The ECG monitor of a patient in the cardiac care unit after an
MI shows ventricular bigeminy with a rate of 50 beats/min.
Which action would the nurse take?
a. Perform defibrillation.
b. Administer IV amiodarone.
c. Prepare for pacemaker insertion.
d. Assess the patient's response.
d
. In the patient with supraventricular tachycardia, which
assessment indicates decreased cardiac output?
a. Hypertension and dyspnea
b. Chest pain and palpitations
c. Abdominal distention and tachypnea
d. Bounding pulses and a systolic murmur
b
The nurse prepares a patient for elective synchronized cardioversion. Which
information would the nurse consider in
planning for the procedure?
a. Defibrillation delivers a lower dose of electrical energy.
b. Cardioversion is a treatment for atrial bradydysrhythmias.

c. Defibrillation delivers a shock during the QRS complex.
d. Cardioversion is painful for an awake patient.
d
Which patient teaching points would the nurse include when
providing discharge instructions to a patient with a new permanent
pacemaker? (select all that apply)
a. Avoid or limit air travel.
b. Take and record a daily pulse rate.
c. Obtain and wear a Medic Alert ID device at all times.
d. Avoid lifting arm on the side of the pacemaker above
shoulder.
e. Do not use a microwave oven because it interferes with
pacemaker function.
bcd
The nurse is interpreting an ECG strip to determine whether there is a delay in
impulse
conduction above the ventricles. Which of the following components of an
ECG strip should
the nurse measure?
a. P wave
b. P-R interval
c. Q-T interval
d. QRS complex
ANS: B The P-R interval represents depolarization of the atria, atrioventricular (AV)
node, bundle of His, bundle branches, and the Purkinje fibres. The QRS represents
ventricular depolarization. The Q-T interval represents depolarization and
repolarization of the entire conduction system.
A patient has a junctional escape rhythm on the monitor. The nurse will expect
the patient to
have a heart rate of how many beats/minute?
a. 20-30
b. 40-60

The nurse obtains a monitor strip on a patient who has had a myocardial
infarction and makes
the following analysis: P wave not apparent, ventricular rate 162, R-R interval
regular, P-R
interval not measurable, and QRS complex wide and distorted, QRS duration
0.18 second.
Which of the following cardiac rhythms should the nurse interpret from these
findings?
a. Atrial fibrillation
b. Sinus tachycardia
c. Ventricular fibrillation
d. Ventricular tachycardia
D
The absence of P waves, wide QRS, rate >150, and the regularity of the rhythm
indicate ventricular tachycardia. Atrial fibrillation is grossly irregular, has a narrow
QRS configuration, and has fibrillatory atrial activity. Sinus tachycardia has P waves.
Ventricular fibrillation is irregular and does not have a consistent QRS duration.
The nurse notes that a patient's cardiac monitor shows that every other beat is
earlier than
expected, has no P wave, and has a QRS complex with a wide and bizarre
shape. How should
the nurse document the rhythm?
a. Ventricular couplets
b. Ventricular bigeminy
c. Ventricular R-on-T phenomenon
d. Ventricular multifocal contractions
, Page 4 of 71
ANS: B Ventricular bigeminy describes a rhythm in which every other QRS complex
is wide and bizarre looking. Pairs of wide QRS complexes are described as couplets.
There is no indication that the premature ventricular contractions (PVCs) are
multifocal or that the R-on-T phenomenon is occurring.
The nurse is caring for a patient who has a normal cardiac rhythm and a heart
rate of 72
beats/minute, except that the P-R interval is 0.24 seconds. Which of the
following actions
should the nurse implement?
a. Notify the patient's health care provider immediately.
b. Administer atropine per agency bradycardia protocol.
c. Prepare the patient for temporary pacemaker insertion.
d. Document the finding and continue to monitor the patient.
ANS: D First-degree atrioventricular (AV) block is asymptomatic and requires
ongoing monitoring because it may progress to more serious forms of heart block.
The rate is normal, so there is no indication that atropine is needed. Immediate
notification of the health care provider about an asymptomatic rhythm is not
necessary.
The nurse is caring for a patient who was admitted with a myocardial infarction
and
experiences a 50-second episode of ventricular tachycardia, then converts to
sinus rhythm
with a heart rate of 98 beats/minute. Which of the following actions should the
nurse take
next?
a. Notify the health care provider.
b. Perform synchronized cardioversion.
c. Administer the PRN IV lidocaine.
d. Document the rhythm and monitor the patient.
C
The nurse administers IV atropine to a patient with symptomatic type 1,
second-degree
atrioventricular (AV) block. Which of the following findings indicate that the
