A. atropine 0.5 mg IV

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

A. give an immediate unsynchronized high-energy shock (defibrillation dose)

What action minimizes the risk of air entering the victim's stomach during bag-mask ventilation? A. ventilating until you see the chest rise B. ventilation as quickly as you can C. squeezing the bad with both hands D. delivering the largest breath you can

A. ventilating until you see the chest rise

B. at least 2 inches

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

B. epinephrine 1 mg IV

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

B. start high-quality CPR

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 mask D. providing just enough volume for the chest to rise

B. ventilation too quickly

You are the code team leader and arrive to find a patient with CPR in progress. On the next rhythm check, you see the rhythm shown here (looks like normal sinus rhythm). Team members tell you that the patient was well but reported chest discomfort and then collapsed. She has no pulse or respirations. Bag-mask ventilations are producing visible chest rise, and IO access has been established. which intervention would be your next action? A. atropine 1 mg B. dopamine at 10 to 20 mcg/kg per minute C. epinephrine 1 mg D. intubation and administration of 100% oxygen

C. epinephrine 1 mg

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

C. give epinephrine 1 mg IV / IO

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

C. resume chest compressions

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

D. 100 to 120 compressions per minute

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
