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? Select the correct answer to this question. Rib fracture Esophageal injury Pneumothorax Hypertension ✔✔Pneumothorax 1 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? Select the correct answer to this question. 5 to 10 mL 10 to 20 mL Final Exam ACLS Questions and Answers 100% Pass 20 to 30 mL 30 to 40 mL ✔✔When administering medications during a cardiac arrest, all medications administrated through the IV or intraosseous infusion route should be followed by a 10- to 20- mL fluid bolus. 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? Wide-complex ventricular rhythm and tall, peaked T waves ST-segment changes, T-wave inversion Flat T waves, prominent U waves and possibly prolonged QT intervals Narrow-complex ventricular tachycardia ✔✔Wide-complex ventricular rhythm and tall, peaked T waves In hyperkalemia the patient's 12-lead ECG rhythm strip will show wide-complex ventricular rhythm and tall, peaked T waves. A patient with an ischemic stroke arrives at the emergency department at 2 a.m. The patient's symptoms started about 12:30 a.m. After completing the necessary assessments, the healthcare team diagnoses an ischemic stroke, and the patient is determined to be a candidate for 7:50 p.m. ✔✔2 Within 20 minutes of the patient's arrival, a comprehensive neurologic assessment should be completed and brain imaging should be performed. That would be 7:30 p.m. for this patient. The emergency department team is providing care to a patient who is experiencing ventricular tachycardia. The patient's serum electrolyte levels are a contributing cause of the patient's current condition. Which electrolyte imbalance(s) would most likely be involved? Select all correct options that apply. Hyperkalemia Hypochloremia Hypernatremia Hypomagnesemia Hypocalcemia ✔✔Hypomagnesemia Hypocalcemia 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? ✔✔The rhythm is ventricular fibrillation. Precipitating causes of ventricular fibrillation include electrocution, myocardial ischemia or infarction, shock, stimulant overdose and ventricular tachycardia. electrocution A patient enters the emergency department in respiratory compromise. The team is monitoring the patient using capnography and identifies that ETCO2 levels are initially 33 mmHg and later 40 mmHg. From these readings, the team identifies that the patient is progressing in what stage of respiratory compromise? Respiratory acidosis Respiratory failure Respiratory distress Respiratory arrest ✔✔3 Capnography can objectively assess the severity of a patient's respiratory distress. Early on, the patient will often hyperventilate, leading to hypocapnia that is reflected by a low ETCO2 value (less than 35 mmHg). As respiratory distress increases, and the patient begins to tire, the ETCO2 value may return to the normal range (35 to 45 mmHg). However, if the patient progresses to respiratory failure, the ETCO2 level will increase to greater than 45 mmHg, which indicates hypoventilation. 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? Atrial fibrillation Ventricular tachycardia Ventricular fibrillation Atrial flutter ✔✔Atrial flutter 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 would deliver 1 ventilation at which interval? Every 3 to 4 seconds Every 5 to 6 seconds Every 7 to 8 seconds Acidosis Hypothermia ✔✔Tension pneumothorax Prearrest signs of tension pneumothorax in the advanced stage include jugular venous distension, cyanosis, apnea and hyperresonance on percussion. Difficulty ventilating the patient may also be a sign of tension pneumothorax. A 40-year-old patient in the waiting room of the primary care provider's office approaches a staff member and says, "I'm having really severe, crushing chest pain that is moving to both my arms." The patient is diaphoretic and dyspneic. Which action would be appropriate for the staff member to take? Activate the emergency medical services system. Take the patient to an exam room immediately. Give the patient an aspirin. Obtain a 12-lead ECG. ✔✔Activate the emergency medical services system. 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 care for the patient, including initiating cardiac monitoring and pulse oximetry; providing supplemental oxygen and ensuring adequate ventilation; and obtaining 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? Amiodarone 150 mg over 10 minutes Atropine 0.5 mg every 3 to 5 minutes Dopamine 5 to 10 mcg/min Epinephrine 2 to 10 mcg/min ✔✔Atropine 0.5 mg every 3 to 5 minutes A patient is brought to the emergency department by their spouse. The spouse says, "I think it's a stroke." The stroke team assesses the patient using the National Institutes of Health Stroke Scale (NIHSS). Which area(s) would the team include in this assessment? Select all correct options that apply. Facial palsy Level of consciousness Language deficits Visual function Cranial nerve function ✔✔Level of consciousness Language deficits Visual function A patient is brought into the emergency department with a suspected opioid overdose. The patient is in cardiac arrest. Which action would be the team's priority? Select the correct answer to this question. Giving naloxone intravenously (IV) Obtaining a 12-lead electrocardiogram (ECG) Administering supplemental oxygen Initiating high-quality CPR ✔✔Initiating high-quality CPR Although no evidence supports any benefit to naloxone administration during cardiac arrest, administration of naloxone during both respiratory and cardiac arrest is recommended when opioid overdose is suspected. However, for a patient in cardiac arrest, high-quality CPR is prioritized over the administration of naloxone. A patient with a diagnosis of ACS is experiencing cardiogenic shock. Which adjuvant therapy would be contraindicated? Select the correct answer to this question. Adenosine administration Sedation Vagal maneuvers Synchronized cardioversion ✔✔Vagal maneuvers A patient experiencing an unstable bradyarrhythmia does not respond to atropine. Which interventions could the healthcare provider use next? Select all correct options that apply. Carotid massage Epinephrine or dopamine infusio Transcutaneous pacing Synchronized cardioversion ✔✔Epinephrine or dopamine infusio Transcutaneous pacing 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? ✔✔ventricular tachycardia A patient with suspected acute coronary syndromes (ACS) is placed on a cardiac monitor.

At the fourth intercostal space, right sternal border On the lower right abdomen On the lower left abdomen Under the left clavicle, at the midclavicular line ✔✔On the lower right abdomen 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? Select the correct answer to this question. Acidosis Hyperkalemia Hypoxia Hypothermia ✔✔Hyperkalemia Suspect hyperkalemia in all patients with acute or chronic renal failure who exhibit a wide- complex ventricular rhythm or tall, peaked T waves on an ECG before cardiac arrest. 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? Select all correct options that apply. A patient experiencing STEMI comes to the emergency department of a large medical center at 9:30 p.m. The patient states that the symptoms started about 8 p.m. After confirming the diagnosis and initiating care, the healthcare team schedules the patient 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? Select the correct answer to this question. 11:00 p.m. 12:00 a.m. 1:00 a.m. 1:30 a.m. ✔✔11:00 p.m. Reperfusion therapy should be administered within 1 hour, 30 minutes of the patient's first medical contact if the patient does not need to be transferred to another facility. The patient arrived at 9:30 p.m., so the latest the therapy should be administered would be 11 p.m. Assessment of a patient reveals an ETCO2 level of 55 mmHg and an arterial oxygen saturation (SaO2) level of 88%.
