ALSACLS-RED CROSS FINAL EXAM WITH 100% CORRECT QUESTIONS AND ANSWERS

ALSACLS-RED CROSS FINAL EXAM WITH 100% CORRECT QUESTIONS AND ANSWERS A patient isbrought into the emergency department. The patient does nothavea pulse. The cardiac monitor shows the following rhythm. The team interprets this as which condition? - answer-Ventricular tachycardia A patient with acute renal failure experiences cardiac arrest. Just before the cardiac arrest, thepatient's ECG showedpeaked T waves. What mightbecausing thepatient's cardiac arrest? - answer-Hyperkalemia 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 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 abolus of fluid. How much wouldtheteam member give? -answer- 10 to 20 mL The resuscitation team suspects that hyperkalemia is the cause of cardiac arrest in a patientbrought totheemergencydepartment. Whichfinding ona12- lead ECG would confirm this suspicion? – answer - Wide-complex ventricular rhythm or tall, pointed T waves A patient with dyspnea and a change in mental status arrives at the emergency department. The healthcare team completes the necessary assessments and begins to carefor thepatient, including initiatingcardiac monitoring,pulse oximetry, supplemental oxygen and vascular access. The team reviews the patient's ECG rhythm strip, as shown in the following figure. Which agent would the team most likely administer? – answer - Atropine 0.5 mg every 4 to 5 minutes A patient experiencing an unstable bradyarrhythmia does not respond to atropine or transcutaneouspacing. Whichintervention wouldthehealthcare providerusenext? - answer- Administration of an epinephrine infusion A patient's ECG reveals a tachyarrhythmia. The patient is hemodynamically stable and has aheart rate ranging from 120 to 135 beats per minute. Based onthe findings of the secondary assessment, whichstatement(s)by thepatient would theteam interpretas a possible contributing cause? - answer-1. "I've had a terrible cold with a horrible cough and fever the past week." 2. "I'vebeensoanxious lately becauseI just lost my job." 3. "I'vebeenvomitingfor thepast2days from agastrointestinalbug." A patient's ECG reveals a narrow QRS complex with a regular rhythm, indicating a narrow-complex supraventricular tachyarrhythmia. The patient is hemodynamically stable. Which intervention would be initiated first? - answer-Vagal maneuvers A patient in the telemetry unit is stable. Cardiac monitoring indicates the patient has ventricular tachycardia with apulse. Furtherassessment reveals that the corrected QT interval is greater than 0.46 seconds. Which treatment would be appropriate at this time? - answer-Synchronized cardioversion An ECG strip of a patient in the emergency department reveals the following rhythm. Whichfeature would thehealthcareprovider interpretas indicating atrial fibrillation? - answer-Absence of discrete P waves and presence of irregularly irregular QRS complexes A 30-year-old patient has beenbrought to the emergency department infull cardiac arrest. Thecardiac monitorshows thefollowing rhythm. Interpretationof this rhythm would suggest which of the following as a possible precipitating factor? - answer- Electrocution Cardiac monitoring ofapatient incardiacarrest reveals ventricular fibrillation. What intervention would the team perform next? - answer-Administer 1 shock. A patient has experienced return of spontaneous circulation (ROSC) after cardiac arrest. Thehealthcareteam is conducting a secondary assessment to determine thepossible cause of the patient's cardiac arrest. Beforethe arrest, the patient exhibited jugular venous distension, cyanosis, apneaand hyperresonance on percussion. The patient was alsodifficult toventilateduring theresponse. Theteam would most likely suspect which condition as the cause? - answer-Tension pneumothorax A patient incardiacarrest experiences returnof spontaneous circulation. Aspart of post-cardiacarrestcare, thepatient 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? - answer-1. SaO2 92% 2. PaCO2 35 mmHg 3. ETCO2 50 mmHg After cardiac arrest and successful resuscitation, the patient has a return of spontaneous circulation. The patient is unable to follow verbal commands and has a Glasgow Coma Scalescoreof 7. Targeted temperature management is initiated. Which method(s) would beappropriatefor theresuscitationteam touse? - answer-1. Applying cooling blankets to the patient's body 2. Giving anice-cold IVfluidbolus 3. Usinganendovascular catheter A 40-year-old patient in the waiting room of the primary care provider's office approachesastaff memberand says, "I'm having really severe, crushing chest painthat is moving to both my arms." The patient is diaphoretic and dyspneic. Which action would be appropriate for the staff member to take? - answerActivate the emergency medical services system. A patient with suspected acute coronary syndromes (ACS) is placed on a cardiac monitor. Thepatient is complainingofdyspnea and isgiven supplemental oxygen. Theproviderdetermines that theoxygenis effectivebasedon which SaO2level? -answer- 95% A 35-year-old female patient's ECG is consistent with STEMI. The ECG reveals a new ST-segmentelevationat theJpoint inleadsV2andV3 of at least whichsize? -answer0.15 mV A patient with STEMI is experiencing chest pain that is refractory to sublingual nitroglycerin. Intravenous nitroglycerin is prescribed. When administering this medication, it would betitrated to maintain whichsystolic bloodpressure? - answer-90 mmHg A patient experiencing STEMI comes tothe emergencydepartmentof alarge medical center at 9:30 p.m. The patient states that the symptoms started about 8 p.m. After confirming thediagnosis andinitiatingcare, thehealthcareteam schedules thepatient for percutaneous coronary intervention (PCI). The facility is capable of administering PCI. To achieve the best outcomes, therapy should be administered to this patient by which time? - answer-11:00 p.m. A patientpresents totheemergencydepartment with mild to moderate recurrentchest pain, without any nausea or vomiting. A 12-lead ECG is obtained and shows ST- segment depression with transient T-wave elevation indicative of NSTE-ACS. Cardiac enzyme levels are obtained and are not elevated. These findings suggest which condition? - answer-Unstable angina A patient isbeing treated intheemergencydepartment and isdetermined to have NSTE-ACS. Invasive management is planned based on which finding? - answer-Ventricular tachycardia A patient presents to the emergency department with suspected ACS. Electrocardiogram and cardiac biomarkers show thepatienthas ST-segment elevation myocardial infarction (STEMI). Physical examination reveals signs of left ventricular dysfunction. Which finding(s) would support this? - answer-1. Pulmonary edema 2. Crackles 3. Hypotension
