ACLS EXAM PREP B| 50 QUESTIONS AND ANSWERS.

What should be done to minimize interruptions in chest compressions during CPR? Continue CPR while the defibrillator is charging. which condition is an indication to stop or withhold resuscitative efforts? Safety threat to providers. After verifying the absence of a pulse, you initiate CPR with adequate bag-mask ventilation. The patient's lead II ECG appears below. What is your next action? (strip missing displays PEA) IV or IO access After verifying unresponsiveness and abnormal breathing, you activate the emergency response team. What is your next action? Check for pulse What is the recommendation on the use of cricoid pressure to prevent aspiration during cardiac arrest? Not recommended for routine use What survival advantages does CPR provide to a patient in ventricular fibrillation? Produces a small amount of blood flow to the heart. What is the recommended compression rate for performing CPR? At least 100 per minute EMS personnel arrive to find a patient in cardiac arrest. Bystanders are performing CPR. After attaching a cardiac monitor, the responder observes the following rhythm strip. What is the most important early intervention? (strip missing displays Ventricular fibrillation) Defibrillation A patient remains in ventricular fibrillation despite 1 shock and 2 minutes of continuous CPR. Administer a 2nd shock What is the recommended next step after a defibrillation attempt? Begin CPR, starting with chest compressions. Which of the following is the recommended first choice for establishing intravenous access during the attempted resuscitation of a patient in cardiac arrest? Antecubital What is the recommended first intravenous dose of aAmiodarone for a patient with refractory ventricular fibrillation? 300mg IV/IO drug administration during CPR should be given rapidly during compressions How often should the team leader switch chest compressors during a resuscitation attempt? Every 2 minutes Which finding is a sign of ineffective CPR? PETCO2 <10 mm Hg A team leader orders 1mg of epinephrine, and a team member verbally acknowledges when the medication is administered. What element of effective resuscitation team dynamics does this represent? Closed-loop communication How long should it take to perform a pulse check during the BLS survey? 5-10 seconds Your team arrives to find a 59-year-old man lying on the kitchen floor. You determine that he is unresponsive and notice that he is taking agonal breaths. What is the next step in your assessment and management of this patient? Check the patient's pulse Which treatment or medication is appropriate for the treatment of a patient in asystole? Epinephrine An AED advises a shock for a pulseless patient lying in snow. What is the next action? Administer the shock immediately and continue as directed by the AED. What is the minimum depth of chest compressions for an adult in cardiac arrest? 2 inches A patient with pulseless ventricular tachycardia is defibrillated. What is the next action? Start chest compressions at a rate of at least 100/min. You have completed your first 2-minute period of CPR. You see an organized, nonshockable rhythm on the ECG monitor. What is the next action? Have a team member attempt to palpate a carotid pulse. Emergency medical responders are unable to obtain a peripheral IV for a patient in cardiac arrest. What is the next most preferred route for drug administration? Intraosseous (IO) What is the appropriate rate of chest compressions for an adult in cardiac arrest? At least 100/min You are receiving a radio report from an EMS team en route with a patient who may be having an acute stroke. The hospital CT scanner is not working at this time. What should you do in this situation? Divert the patient to a hospital 15 minutes away with CT capabilities . A 53-year-old man has shortness of breath, chest discomfort, and weakness. The patients blood pressure is 102/59 mm hg, the heart rate is 230/min, the respiratory rate is 16 breaths/min, and the pulse oximetry reading is 96%. The lead II ECG is displayed below. Patient has a peripheral IV is in place. What is the next action? (strip missing displays tachycardic sinus rhythm with narrow QRS) Vagal maneuvers A 49-year-old man has retrosternal chest pain radiating into the left arm. The patient is diaphoretic, with associated shortness of breath. The blood pressure is 130/88 mm Hg, the heart rate is 110/min, the respiratory rate is 22 breaths/min, and the pulse oximetry value is 95%. The patient's 12-lead ECG shows ST-segment elevation in the anterior leads. First responders administered 160 mg of aspirin, and there is a patent peripheral IV. The pain is described as an 8 on a scale of 1 to 10 and is unrelieved after 3 doses of nitroglycerin. What is the next action? Administer 2 to 4 mg of morphine by slow IV bolus. A 56-year-old man reports that he has palpitations but not chest pain or difficulty breathing. The blood pressure is 132/68 mm Hg, the pulse is 130/min and regular, the respiratory rate is 12 breaths/min, and the pulse oximetry reading is 95%. The lead II ECG displays a wide-complex tachycardia. What is the next action after establishing an IV and obtaining a 12-lead ECG? Seeking expert consultation A postoperative patient in the ICU reports new chest pain. What actions have the highest priority? Obtain a 12-lead ECG and administer aspirin if not contraindicated. An 80-year-old woman presents to the emergency department with dizziness. She now states she is asymptomatic after walking around. Her blood pressure is 102/72 mm Hg. She is alert and oriented. Her lead II ECG is below. After you start an IV, what is the next action? (strip missing displays a 2nd degree AV block AKA Wenkebach) Conduct a problem-focused history and physical examination. What is the recommended oral dose of aspirin for patients suspected of having one of the acute coronary syndromes? 160 to 325 mg A responder is caring for a patient with a history of congestive heart failure.
