ACLS Study Guide

ACLS Study Guide A 68-year-old woman presents with light-headedness, nausea, and chest discomfort. Your assessment finds her awake and responsive but ill-appearing, pale, and goodly disphorttie. Her radial is weak, thready, and fast. You are unable to obtain a blood pressure. She has no obvious dependent edema, and her neck veins are flat. Her lung sounds are equal, with moderate rales present bilaterally. The cardiac monitor shows the rhythm seen here. After your initial assessment of this patient, which intervention should be performed next? - answerSynchronized cardioversion Which type of atrioventricular (AV) block best describes this rhythm? - answerSecond degree type II Your patient is in cardiac arrest and has been intubated. To assess CPR quality, which should you do? - answerMonitor the patient's PetCO2 Which facility is the most appropriate EMS destination for a patient with sudden cardiac arrest who achieved return a spontaneous circulation in the field? - answerCoronary reperfusion-capable medical center Which of the following signs is a likely indicator of cardiac arrest in an unresponsive patient? - answerAgonal gasps Which type of atrioventricular (AV) block best describes this rhythm? - answerSecond degree atrioventricular (AV) block type I To properly ventilate a patient with a perfusing rhythm, how often do you squeeze the bag? - answerOnce every 5 to 6 seconds In addition to clinical assessment, which is the most reliable method to confirm and monitor correct placement of an endotracheal (ET) tube? - answerContinuous waveform capnography You are caring for a patient with a suspected stroke whose symptoms started 2 hours ago. The CT scan was normal, with no signs of hemorrhage. The patient does not have any contraindications to fibrinolytic therapy. Which treatment approach is best for this patient? - answerStart fibrinolytic therapy as soon as possible Which best describes this rhythm? - answerThird-degree atrioventricular block What is the recommended range from which a temperature should be selected and maintained constantly to achieve targeted management after cardiac arrest? - answer32 degrees celsius to 36 degrees celsius Which is the recommended first intravenous (IV) dose of amiodarone for a patient with refractory ventricular fibrillation? - answer300mg Which is the primary purpose of a medical emergency team or rapid response team? - answerImproving patient outcomes by identifying and treating early clinical deterioration Which is the recommended next step after a defibrillation attempt? - answerResume CPR, starting with chest compressions EMS providers are treating a patient with suspected stroke. According to the Adult Suspected Stroke Algorithm, which critical action performed by the EMS team will expedite this patient's care on arrival and reduce the time to treatment? - answerAlert the hospital A responder is caring for a patient with a history of congestive heart failure (CHF). The patient is experiencing shortness of breath, a blood pressure (BP) of 68/50 mmHg, and a heart rate of 190/min. The patient's lead II ECG is displayed here. Which best characterizes this patient's rhythm? - answerUnstable supraventricular tachycardia (SVT) Your rescue team arrives to find a 59-year-old man lying on the kitchen floor. You determine that he is unresponsive. Which is the next step in your assessment and management of this patient? - answerCheck the patient's breathing and pulse Which best describes the length of time it should take to perform a pulse check during the BLS Assessment? - answer5 to 10 seconds You instruct a team member to give 0.5 mg atropine IV. Which response is an example of closed-loop communication? - answer"I'll draw up 0.5 mg of atropine." What is an effect of excessive ventilation? - answerDecreased cardiac output If a team member is about to make a mistake during a resuscitation attempt, which best describes the action that the team leader or other team members should take? - answerAddress the team member immediately Which best describes this rhythm? - answerMonomorphic ventricular tachycardia
