EXAM STUDY MATERIALS July 23, 2024 4:26 PM Dysrhythmias Practice Exam Questions With Verified Answers 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 bee ping. 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 ventr icular 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 adenos ine - 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 cardi oversion STAT b) Begin administering anticoagulants EXAM STUDY MATERIALS July 23, 2024 4:26 PM 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 poss ible. 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) Li docaine - 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 a trial flutter. These students recognize that which of the following are seen with atrial flutter? Select all that apply: EXAM STUDY MATERIALS July 23, 2024 4:26 PM 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 receive s 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 Patients with a -fib are at risk for pulmonary and systemic emboli, an d new onset of confusion may indicate a stroke in this patient. Patients with atrial flutter may feel more tired some days than others. A nurse on a CVT unit views the monitor and sees the patient in room 452 has just begun having occasional PVCs. Which ac tion should the nurse take first?
