American Red Cross-ACLS-Final 50 Questions with 100% Verified Solutions

American Red Cross-ACLS-Final 50 Questions with 100% Verified Solutions A patient with suspected acute coronary syndromes (ACS) has a pulse oximetry reading of 86% and is given supplemental oxygen. The provider determines that the supplemental oxygen dose is correct based on which SaO2 level? - ANSWER 93% After cardiac arrest and successful resuscitation, the patient has a return of spontaneous circulation. The patient is unable to follow verbal commands. Targeted temperature management is initiated. Which method(s) would be appropriate for the resuscitation team to use? - ANSWER --Applying cooling blankets to the patient's body -Using an endovascular catheter -Giving an ice-cold IV fluid bolus A patient comes to the emergency department complaining of palpitations and "some shortness of breath." Cardiac monitoring is initiated and reveals the following ECG rhythm strip. The provider interprets this strip as indicating which arrhythmia? - ANSWER -Atrial flutter A 35-year-old female patient's ECG is consistent with STEMI. The ECG reveals a new ST-segment elevation at the J point in leads V2 and V3 of at least which size? - ANSWER -0.15 mV The following capnogram is from a patient experiencing respiratory distress. At which point in the waveform would the patient's ETCO2 level be measured? - ANSWER -D For a patient with third-degree atrioventricular (AV) block and a blood pressure of 70/48 mmHg, what interventions should be considered? - ANSWER --Initiate a dopamine infusion -Administer atropine -Initiate transcutaneous pacing A patient arrives at the emergency department complaining of shortness of breath. The patient has a long history of chronic obstructive pulmonary disease. Assessment reveals respiratory failure. Which action would be the initial priority to address the respiratory failure? - ANSWER -Assisted ventilation with BVM resuscitator The ECG rhythm strip of a patient who arrived in the emergency department complaining of dizziness, syncope and shortness of breath reveals sinus bradycardia. When reviewing the patient's medication history, the healthcare provider identifies which agent(s) as a potential cause of the patient's current condition? - ANSWER --Verapamil -Digoxin -Metoprolol 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 A patient is experiencing respiratory distress secondary to an exacerbation of chronic obstructive pulmonary disease. The patient begins to exhibit signs and symptoms of worsening respiratory function and experiences respiratory arrest. The team intervenes, delivering ventilations via BVM resuscitator. The team should provide ventilations at a rate of 1 ventilation: - ANSWER -Every 6 seconds A patient is being treated in the emergency department and is determined to have NSTE-ACS. Invasive management is planned based on which finding? - ANSWER -Ventricular tachycardia A patient's ECG reveals a narrow QRS complex with a regular rhythm, indicating a narrow-complex supraventricular tachyarrhythmia. The patient is not showing signs of hemodynamic compromise. Which intervention would be initiated first if it does not delay other interventions? - ANSWER -Vagal maneuvers A resuscitation team is debriefing following a recent event. A patient experienced cardiac arrest, and advanced life support was initiated. The patient required the placement of an advanced airway to maintain airway patency. Which statement indicates that the team performed high-quality CPR? - ANSWER -"We provided chest compressions at a rate of 100 to 120 compressions per minute while giving 1 ventilation every 6 seconds without pausing compressions." A patient experiences cardiac arrest, and the resuscitation team initiates ventilations using a bag-valve-mask (BVM) resuscitator. The development of which condition during the provision of care would lead the team to suspect that improper BVM technique is being used? - ANSWER -Pneumothorax 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 Which statements accurately reflect the recommendations for post-cardiac arrest neuroprognostication? - ANSWER --Post-cardiac arrest neuroprognostication should be multimodal. -Decision-making related to the continuation or withdrawal of life-sustaining treatments should be delayed until 72 hours after return of spontaneous circulation (ROSC) and following return to normothermia. The resuscitation team suspects that hyperkalemia is the cause of cardiac arrest in a patient brought to the emergency department. Which finding on a 12-lead ECG would confirm this suspicion? - ANSWER -Wide-complex ventricular rhythm and tall, peaked T waves A 30-year-old patient has been brought to the emergency department in 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 What is the correct technique for performing left uterine displacement (LUD) for a pregnant patient in cardiac arrest whose fundus is at or above the umbilicus? - ANSWER -Position yourself on the patient's left side. Reach across the patient, place both hands on the right side of the uterus and pull the uterus to the left and up. Which areas are evaluated using the National Institutes of Health Stroke Scale (NIHSS)? - ANSWER --Visual function -Language deficits -Facial Palsy -Level of consciousness A patient is in cardiac arrest. The underlying cause is thought to be opioid toxicity. Which statement accurately describes the use of naloxone for this patient? -
