DYSRHYTHMIAS PRACTICE
QUESTIONS 2025 WITH CORRECT
ANSWERS (GRADE A+)




You are the nurse working on the telemetry unit and you have finally gotten to sit down to work on some
1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1




charting. Suddenly the heart monitors at the station start beeping. Patient in room 18 is showing this rhythm
1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1




on the monitor. The medical team advances together into the room and finds them unconscious. What is
1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1




priority action by the nurse?1 1 1 1




A) Prepare to administer adenosine to the patient
1 1 1 1 1 1 1




B) Begin chest compressions
1 1 1




C) Prepare for defibrillation
1 1 1




D) Check for a pulse - correct answers Answer: D
1 1 1 1 1 1 1 1 1




A pulse would be assessed for first. Then the patient will be defibrillized and chest compressions will begin
1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1




immediately.

,The patient who has recently been experiencing runs of ventricular tachycardia suddenly loses
1 1 1 1 1 1 1 1 1 1 1 1 1




consciousness. The patient is defibrillated, and the rate returns as the following. What should the nurse do 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1




first?

A) Begin compressions
1 1




B) Shock the client again immediately
1 1 1 1 1




C) Prepare for intubation
1 1 1




D) Administer adenosine - correct answers Answer: A
1 1 1 1 1 1 1




Following defibrillation, CPR is immediately initiated if a perfusable rhythm is not initiated. The client may
1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1




need to be shocked again, but chest compressions must begin first.
1 1 1 1 1 1 1 1 1 1




The patient with a history of hypertension and diabetes has the following rhythm strip. The patient's vitals are
1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1




as follows: BP 145/89, HR 90, SpO2 95%, RR 19. Which of the following does the nurse expect to do at this time?
1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1




a) Prepare the client for cardioversion STAT
1 1 1 1 1 1




b) Begin administering anticoagulants
1 1 1




c) Grab the crash cart for administration of adenosine
1 1 1 1 1 1 1 1




d) Teach the client about possibility of pacemaker installation - correct answers Answer: B
1 1 1 1 1 1 1 1 1 1 1 1 1




Atrial flutter places the client at high risk for development of clot formation in the atria. Because the client is
1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1




stable at this time, cardioversion or adenosine would not be performed at this time. Before cardioversion can
1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1




occur in a patient, anticoagulant therapy should be begun at least 48 hours beforehand if possible.
1 1 1 1 1 1 1 1 1 1 1 1 1 1 1




The nurse is preparing to administer adenosine to the patient with the following rhythm which is
1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1




symptomatic. What should the nurse plan on having in the patient room? Select All That Apply: 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1




a) Physician
1




b) Crash cart
1 1




c) IV pump
1 1




d) EKG monitor
1 1




e) Lidocaine - correct answers Answer: A, B, and D
1 1 1 1 1 1 1 1 1

, Adenosine is administered as a very quick IV push. The physician must be present in the room and the crash
1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1




cart must be on hand. An ekg monitor should be in the room to monitor the effectiveness of the medication.
1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1




The nurse has just administered adenosine via IV push and sees the following rhythm on the monitor. What is
1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1




the nurse's priority intervention?
1 1 1




a) Apply conductive gel and defibrillate the patient
1 1 1 1 1 1 1




b) Document the findings and continue to monitor
1 1 1 1 1 1 1




c) Administer another mg of the medication
1 1 1 1 1 1




d) Begin chest compressions - correct answers Answer: B
1 1 1 1 1 1 1 1




This finding would be expected upon administration of adenosine. The rhythm should then begin again in
1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1




some other rhythm, hopefully normal sinus rhythm. It would be important to document the exact time of this
1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1




change and continue to monitor the change back to NSR. If this change does not occur, or if another rhythm is
1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1




produced, appropriate action would then be taken based on the result.1 1 1 1 1 1 1 1 1 1




A group of nursing students are discussing atrial flutter. These students recognize that which of the following
1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1




are seen with atrial flutter? Select all that apply:
1 1 1 1 1 1 1 1




1) Ventricular rate of 220-300 bpm.
1 1 1 1 1




2) Regular rhythm
1 1




3) Saw-tooth pattern
1 1




4) Measurable PR interval
1 1 1 1




5) Long QRS interval - correct answers Answer(s): 2, 3
1 1 1 1 1 1 1 1 1




The ATRIAL rate is 250-400 bpm. Ventricular is about 75-150. The rhythm is regular, with the P wave appearing
1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1




as little flutter or a "saw tooth pattern". The PR interval is not measurable r/t this saw-tooth P wave. The QRS is
1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1




normal.



A nursing student is aware that which of the following is the treatment for unstable atrial flutter?
1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1




1) Adenosine (Adenocard) 6 mg rapid IVP.
1 1 1 1 1 1




2) Cardioversion with adjacent Heparin therapy
1 1 1 1 1




3) Defibrillation STAT followed by CPR.
1 1 1 1 1




4) Altemose 3 mg IVP over 1-2 seconds. - correct answers Answer: 2
