DYSRHYTHMIAS NCLEX QUESTIONSMINE WITH CORRECT ANSWERS
You are the nurse working on the telemetry unit and you have finally gotten to sit down
g g g g g g g g g g g g g g g g
to work on some charting. Suddenly the heart monitors at the station start beeping. The
g g g g g g g g g g g g g g g
patient in room 18 is showing a ventricular fibrillation rhythm on the monitor. The
g g g g g g g g g g g g g g
medical team advances together into the room and finds them unconscious. What is
g g g g g g g g g g g g g
priority action by the nurse?
g g g g g
A) Prepare to administer adenosine to the patient
g g g g g g g
B) Begin chest compressions
g g g
C) Prepare for defibrillation
g g g
D) Check for a pulse - Correct Answer - D) Check for a pulse
g g g g g g g g g g g g g
A pulse would be assessed first. Then the patient will be defibrillated and chest
g g g g g g g g g g g g g
compressions will begin immediately.
g g g g
The nurse sees a sinus tachycardia rhythm on the monitor. Which of the following lab
g g g g g g g g g g g g g g
values does the nurse identify as being most likely to have caused this dysrhythmia?
g g g g g g g g g g g g g g
a) K 3.0g g
b) Ca 10.5
g g
c) Hgb 9
g g
d) Magnesium 2.1 - Correct Answer - c) Hgb 9
g g g g g g g g g
Anemia can contribute to sinus tachycardia.
g g g g g
The patient who has recently been experiencing runs of ventricular tachycardia
g g g g g g g g g g
suddenly loses consciousness. The patient is defibrillated, and the rate returns as
g g g g g g g g g g g g
ventricular fibrillation. What should the nurse do first?
g g g g g g g g
A) Begin compressions
g g
B) Shock the client again immediately
g g g g g
C) Prepare for intubation
g g g
D) Administer adenosine - Correct Answer - A) Begin compressions
g g g g g g g g g
Following defibrillation, CPR is immediately initiated if a perfusable rhythm is not
g g g g g g g g g g g
initiated. The client may need to be shocked again, but chest compressions must begin
g g g g g g g g g g g g g g
first.

A patient with cardiomyopathy has been given an ICD. Which of the following
g g g g g g g g g g g g
medications would the nurse expect to see in the MAR for this patient?
g g g g g g g g g g g g g
, A) Warfarin
g
B) Cardizem
g
C) Nitroglycerin
g
D) Digoxin - Correct Answer - B) Cardizem
g g g g g g g
Antiarrhythmic medications are prescribed with the use of an ICD in order to prevent theg g g g g g g g g g g g g g
tachycardia (or other deadly arrhythmias) from occurring in the first place. This makes
g g g g g g g g g g g g g
sure that the ICD is used only when absolutely necessary.
g g g g g g g g g g
The patient with a history of hypertension and diabetes has a rhythm strip indicating
g g g g g g g g g g g g g
atrial flutter. The patient's vitals are as follows: BP 145/89, HR 90, SpO2 95%, RR 19.
g g g g g g g g g g g g g g g g
Which of the following does the nurse expect to do at this time?
g g g g g g g g g g g g g
a) Prepare the client for cardioversion STAT
g g g g g g
b) Begin administering anticoagulants
g g g
c) Grab the crash cart for administration of adenosine
g g g g g g g g
d) Teach the client about possibility of pacemaker installation - Correct Answer - b)
g g g g g g g g g g g g g
Begin administering anticoagulants
g g g
Atrial flutter places the client at high risk for development of clot formation in the atria.
g g g g g g g g g g g g g g g
Because the client is stable at this time, cardioversion or adenosine would not be
g g g g g g g g g g g g g g
performed at this time. Before cardioversion can occur in a patient, anticoagulant
g g g g g g g g g g g g
therapy should be begun at least 48 hours beforehand if possible.
g g g g g g g g g g g
The nurse is preparing to administer adenosine to the patient with the following rhythm
g g g g g g g g g g g g g
which is symptomatic. What should the nurse plan on having in the patient room?
g g g g g g g g g g g g g g
a) Physician
g
b) Crash cart
g g
c) IV pump
g g
d) EKG monitor
g g
e) Lidocaine - Correct Answer - a) Physician
g g g g g g g
b) Crash cart
g g
d) EKG monitor
g g
Adenosine is administered as a very quick IV push. The physician must be present in
g g g g g g g g g g g g g g
the room and the crash cart must be on hand. An ekg monitor should be in the room to
g g g g g g g g g g g g g g g g g g g
monitor the effectiveness of the medication.
g g g g g g
The nurse has just administered adenosine via IV push and sees the following rhythm
g g g g g g g g g g g g g
on the monitor. What is the nurse's priority intervention?
g g g g g g g g g
a) Apply conductive gel and defibrillate the patient
g g g g g g g
b) Document the findings and continue to monitor
g g g g g g g
c) Administer another mg of the medication
