The nurse notes that the client's cardiac rhythm strips show more P
waves than QRS complexes. There is no relationship between the atria
and the ventricles. How should the nurse interpret this rhythm strip?
First degree
atrioventricular (AV) block Second degree AV block Mobitz I
(Wenckebach) Second degree AV block Mobitz II Third
degree AV block (complete heart block)
D. Third degree AV block (complete heart block)
A client's cardiac monitor indicates ventricular tachycardia. The
nurse assesses the client and identifies an increase in apical pulse
rate from 100 to 150 beats per minute. What is an appropriate
treatment plan?
Amiodarone bolus
Intracardiac epinephrine Insertion of a pacemaker
Cardiopulmonary resuscitation (CPR) Rationale
A. Amiodarone bolus
What potentially dangerous adverse effect of an intravenous titrated
drip of lidocaine should the nurse immediately report to the
healthcare provider?
Tremors
Anorexia Tachycardia Hypertension
A. Tremors
The nurse is interpreting the client's rhythm strip and finds that
the P and QRS waves are consistent, with a P wave preceding every QRS
complex. The PR interval is 0.26 seconds long. The rate is 64 beats
per minute. How should the nurse interpret this rhythm?
Complete heart
block Normal sinus rhythm (NSR) Sinus rhythm with
first degree AV block Sinus rhythm with second degree
atrioventricular (AV) block
C. Sinus rhythm with first degree AV block
It is determined that a client with heart block will require
implantation of a permanent pacemaker to assist heart function. In
explaining the pacemaker to the client, what does the nurse say it is
necessary for?
Simulating a normal
heartbeat Shocking the atrioventricular (AV) node to
contract Slowing the heart to a more normal rate
Synchronizing the action of the heart valves
A. Simulating a normal heartbeat
A client is receiving metoprolol. Which side effect should the nurse
teach the client to expect?
Dizziness with
strenuous activity Acceleration of the heart rate after
eating a heavy meal Flushing sensations for a few minutes
after taking the drug Pounding of the heart for a few
minutes after taking the drug
A. Dizziness with strenuous activity
The nurse notices that the client's cardiac rhythm has become
irregular; QRS complexes are missing after some of the P waves. The
nurse also notes that the PR intervals become progressively longer
until a P wave stands without a QRS; then the PR interval is normal
with the next beat and starts the cycle again with each successive PR
interval getting longer until there is a missing QRS. The nurse
notifies the primary healthcare provider. Which rhythm does the nurse
share with the provider?
First degree
atrioventricular (AV) block Second degree AV block Mobitz I
(Wenckebach) Second degree AV block Mobitz II Third
degree AV block (complete heart block)
B. Second degree AV block Mobitz I (Wenckebach)
A client is admitted to the hospital with multiple signs and symptoms
associated with a cardiac problem. What clinical finding alerts the
nurse that the primary healthcare provider probably will insert a pacemaker?
Angina Chest
pain Heart block Tachycardia
C. Heart block
A nurse identifies premature ventricular complexes (PVCs) on a
client�s cardiac monitor. What does the nurse conclude that these
complexes are a sign of?
Atrial
fibrillation Cardiac irritability Impending
heart block Ventricular tachycardia
B. Cardiac irritability
A client is admitted to the cardiac care unit with a myocardial
infarction. The cardiac monitor reveals several runs of ventricular
tachycardia. The nurse anticipates that the client will be receiving a
prescription for which drug?
Atropine
Epinephrine Amiodarone Sodium bicarbonate
C. Amiodarone
When a client exhibits severe bradycardia, which type of drug should
the nurse be prepared to administer?
Cardiac nitrate
Anticholinergic Antihypertensive Cardiac
glycoside
B. Anticholinergic
While a pacemaker catheter is being inserted, the client's heart rate
drops to 38 beats/min. What medication should the nurse expect the
healthcare provider to prescribe?
Digoxin
Lidocaine Amiodarone Atropine sulfate
D. Atropine sulfate
A client with supraventricular tachycardia (SVT) has a heart rate of
170 beats per minute. Following treatment with diltiazem
hydrochloride, what assessment indicates to the nurse that the
diltiazem hydrochloride is effective?
Increased urine
output Blood pressure of 90/60 mm Hg Heart rate of
110 beats per minute No longer complaining of heart
palpations
C. Heart rate of 110 beats per minute
A client with a history of heart failure and hypertension is admitted
with reports of syncope. Which prescribed medication should the nurse
prepare to administer based on the electrocardiogram (ECG) rhythm
strip image?
This rhythm strip reflects sinus bradycardia.
Digoxin
Enalapril Atropine Metoprolol
C. Atropine
A client is brought to the emergency department with chest pain. The
client asks why an electrocardiogram (ECG) has been prescribed. What
does the nurse explain that the ECG will do?
Indicates acutely
impaired blood flow to the heart muscle Detect altered
heart sounds Determine the flow of blood to the heart
muscle Evaluate the spatial relationship of structures within
the heart
A. Indicates acutely impaired blood flow to the heart muscle
