ACLS Final Exam| Questions and Verified Answers (2023/ 2024 New Update)

ACLS Final Exam| Questions and Verified Answers (2023/ 2024 New Update) Q: An ECG strip of a patient in the emergency department reveals the following rhythm. Which feature would the healthcare provider interpret as indicating atrial fibrillation? Answer: Absence of discrete P waves and presence of irregularly irregular QRS complexes Q: A patient is brought into the emergency department. The patient does not have a pulse. The cardiac monitor shows the following rhythm. The team interprets this as which condition? Answer: Ventricular tachycardia Q: A patient with acute renal failure experiences cardiac arrest. Just before the cardiac arrest, the patient's ECG showed peaked T waves. What might be causing the patient's cardiac arrest? Answer: Hyperkalemia Q: A member of the resuscitation team is preparing to defibrillate a patient in cardiac arrest using a biphasic defibrillator. The team member would set the energy dose according to the manufacturer's recommendations, which is usually: Answer: 120 to 200 joules Q: A member of the resuscitation team is preparing to administer medications intravenously to a patient in cardiac arrest. The team member follows each medication administration with a bolus of fluid. How much would the team member give? Answer: 10 to 20 mL Q: A 30-year-old patient has been brought to the emergency department in full cardiac arrest. The cardiac monitor shows the following rhythm. Interpretation of this rhythm would suggest which of the following as a possible precipitating factor? Answer: Electrocution Q: Cardiac monitoring of a patient in cardiac arrest reveals ventricular fibrillation. What intervention would the team perform next? Answer: Administer 1 shock. Q: A patient has experienced return of spontaneous circulation (ROSC) after cardiac arrest. The healthcare team is conducting a secondary assessment to determine the possible cause of the patient's cardiac arrest. Before the arrest, the patient exhibited jugular venous distension, cyanosis, apnea and hyperresonance on percussion. The patient was also difficult to ventilate during the response. The team would most likely suspect which condition as the cause? Answer: Tension pneumothorax Q: A patient in cardiac arrest experiences return of spontaneous circulation. As part of post-cardiac arrest care, the patient is receiving mechanical ventilation. Which finding(s) would indicate the need for change in the ventilator settings to optimize the patient's ventilation and oxygenation?
