Dysrhythmia and Treatment Modalities Practice
Questions 2025-2026
You are the nurse working on the telemetry unit and you have finally gotten
to sit down to work on some charting. Suddenly the heart monitors at the
station start beeping. Patient in room 18 is showing this rhythm on the
monitor. The medical team advances together into the room and finds them
unconscious. What is priority action by the nurse?
A) Prepare to administer adenosine to the patient
B) Begin chest compressions
C) Prepare for defibrillation
D) Check for a pulse - ANSWER>>ANSWER: D
A pulse would be assessed for first. Then the patient will be defibrillized
and chest compressions will begin immediately.
The patient who has recently been experiencing runs of ventricular
tachycardia suddenly loses consciousness. The patient is defibrillated, and
the rate returns as the following. What should the nurse do first?
A) Begin compressions
B) Shock the client again immediately
C) Prepare for intubation
D) Administer adenosine - ANSWER>>ANSWER: A
Following defibrillation, CPR is immediately initiated if a perfusable rhythm
is not initiated. The client may need to be shocked again, but chest
compressions must begin first.
The patient with a history of hypertension and diabetes has the following
rhythm strip. The patient's vitals are as follows: BP 145/89, HR 90, SpO2
95%, RR 19. Which of the following does the nurse expect to do at this
time?
a) Prepare the client for cardioversion STAT
b) Begin administering anticoagulants
,c) Grab the crash cart for administration of adenosine
d) Teach the client about possibility of pacemaker installation -
ANSWER>>ANSWER: B
Atrial flutter places the client at high risk for development of clot formation
in the atria. Because the client is stable at this time, cardioversion or
adenosine would not be performed at this time. Before cardioversion can
occur in a patient, anticoagulant therapy should be begun at least 48 hours
beforehand if possible.
The nurse is preparing to administer adenosine to the patient with the
following rhythm which is symptomatic. What should the nurse plan on
having in the patient room? Select All That Apply: a) Physician
b) Crash cart
c) IV pump
d) EKG monitor
e) Lidocaine - ANSWER>>ANSWER: A, B, and D
Adenosine is administered as a very quick IV push. The physician must be
present in the room and the crash cart must be on hand. An ekg monitor
should be in the room to monitor the effectiveness of the medication.
The nurse has just administered adenosine via IV push and sees the
following rhythm on the monitor. What is the nurse's priority intervention? a)
Apply conductive gel and defibrillate the patient
b) Document the findings and continue to monitor
c) Administer another mg of the medication
d) Begin chest compressions - ANSWER>>ANSWER: B
This finding would be expected upon administration of adenosine. The
rhythm should then begin again in some other rhythm, hopefully normal
sinus rhythm. It would be important to document the exact time of this
change and continue to monitor the change back to NSR. If this change
does not occur, or if another rhythm is produced, appropriate action would
then be taken based on the result.
, A group of nursing students are discussing atrial flutter. These students
recognize that which of the following are seen with atrial flutter? Select all
that apply:
1) Ventricular rate of 220-300 bpm.
2) Regular rhythm
3) Saw-tooth pattern
4) Measurable PR interval
5) Long QRS interval - ANSWER>>ANSWER(s): 2, 3
The ATRIAL rate is 250-400 bpm. Ventricular is about 75-150. The rhythm
is regular, with the P wave appearing as little flutter or a "saw tooth
pattern". The PR interval is not measurable r/t this saw-tooth P wave. The
QRS is normal.
A nursing student is aware that which of the following is the treatment for
unstable atrial flutter?
1) Adenosine (Adenocard) 6 mg rapid IVP. 2)
Cardioversion with adjacent Heparin therapy 3)
Defibrillation STAT followed by CPR.
4) Altemose 3 mg IVP over 1-2 seconds. - ANSWER>>ANSWER: 2
Cardioversion is used if the patient is unstable. Anticoagulants are used if
the arrhythmia has stuck around for 48 hr +. Adenosine may be used with a
narrow QRS and regular RR interval
A nurse working on a CVT unit receives report from day shift. After
receiving report, which patient should the nurse see first?
1) A 23-year-old professional tennis player with a HR of 47 bpm.
2) A 69-year-old male with atrial fibrillation who has new onset confusion.
3) A 72-year-old female with atrial flutter who reports feeling unusually
tired today and yesterday.
4) A 33-year-old female with sinus tachycardia who is asking for her at-
home Metoprolol. - ANSWER>>ANSWER: 2
