ACLS - Practical Application

ACLS - Practical Application You arrive on the scene to find CPR in progress. Nursing staff report the patient was recovering from a pulmonary embolism and suddenly collapsed. Two shocks have been delivered, and an IV has been initiated. What do you administer now? A. atropine 0.5 mg IV B. epinephrine 1 mg IV C. endotracheal intubation D. transcutaneous pacing - CORRECT ANSWER B. epinephrine 1 mg IV A 45-year-old woman with a history of palpitations develops light-headedness and palpitations. She has received adenosine 6 mg IV for the rhythm shown here (SVT), without conversion of the rhythm. She is n9ow extremely apprehensive. Her blood pressure is 128/70 mm Hg. What is the next appropriate intervention? A. administer adenosine 12 mg IV B. perform unsynchronized cardioversion C. perform vagal maneuvers D. perform synchronized cardioversion - CORRECT ANSWER A. administer adenosine 12 mg IV What is the recommended depth of chest compression for an adult victim? A. at least 1.5 inches B. at least 2 inches C. at least 2.5 inches D. at least 3 inches - CORRECT ANSWER B. at least 2 inches A patient's 12-lead ECG is transmitted by the paramedics and shows a STEMI. When the patient arrives in the emergency department, the rhythm shown here (ST elevation) is seen on the cardiac monitor. The patient has resolution of moderate (5/10) chest pain after 3 doses of sublingual nitroglycerin. Blood pressure is 104/70 mm Hg. Which intervention is most important in reducing this patient's in-hospital and 30-day mortality rate? A. application of transcutaneous pacemaker B. atropine administration C. nitroglycerin administration D. reperfusion therapy - CORRECT ANSWER D. reperfusion therapy A patient has been resuscitated from cardiac arrest. During post-ROSC treatment, the patient becomes unresponsive, with the rhythm shown here (polymorphic ventricular tachycardia). which action is indicated next? A. give an immediate unsynchronized high-energy shock (defibrillation dose) B. give lidocaine 1 to 1.5 mg/kg IV C. perform synchronized cardioversion D. repeat amiodarone 300 mg IV - CORRECT ANSWER A. give an immediate unsynchronized high-energy shock (defibrillation dose) A patient becomes unresponsive. You are uncertain if a faint pulse is present. The rhythm shown here is seen on the cardiac monitor. An IV is in place. Which action do you take next? A. begin transcutaneous pacing B. start high-quality CPR C. administer atropine 1 mg D. administer epinephrine 1 mg IV - CORRECT ANSWER B. start high-quality CPR Your patient is not responsive and is not breathing. You can palpate a carotid pulse. Which action do you take next? A. apply an AED B. obtain a 12-lead ECG C. start an IV D. start rescue breathing - CORRECT ANSWER D. start rescue breathing After initiation of CPR and 1 shock for ventricular fibrillation, this rhythm (ventricular fibrillation) is present on the next rhythm check. A second shock is given, and chest compressions are resumed immediately. An IV is in place, and no drugs have been given. Bag-mask ventilations are producing visible chest rise. What is your next intervention? A. administer 3 sequential (stacked) shocks at 360 J (monophasic defibrillator) B. give amiodarone 300 mg IV / IO C. give epinephrine 1 mg IV / IO D. intubate and administer 100% oxygen - CORRECT ANSWER C. give epinephrine 1 mg IV / IO What is the recommended compression rate for high-quality CPR? A. 50 to 60 compressions per minute B. 70 to 80 compressions per minute C. 90 to 100 compressions per minute D. 100 to 120 compressions per minute - CORRECT ANSWER D. 100 to 120 compressions per minute A 35-year-old woman presents with a chief complaint of palpitations. She has no chest discomfort, shortness of breath, or light-headedness. Her blood pressure is 120/78 mm Hg. Which intervention is indicated first? A. adenosine 3 mg IV bolus B. adenosine 12 mg IV slow push (over 1 to 2 minutes) C. metoprolol 5 mg IV and repeat if necessary D. vagal maneuvers - CORRECT ANSWER D. vagal maneuvers Which action should you take immediately after providing an AED shock? A. check the pulse rate B. prepare to deliver a second shock C. resume chest compressions D. start rescue breathing - CORRECT ANSWER C. resume chest compressions Which action is likely to cause air to enter the victim's stomach (gastric inflation) during bag-mask ventilation? A. giving breaths over 1 second B. ventilation too quickly C. providing a good seal between the face and the mas
