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, without conversion of the rhythm. She is now extremely apprehensive. Her blood pressure is 128\/70 mm Hg. What is the next appropriate intervention? SVT<\/p>\n\n\n\n

After initiation of CPR and 1 shock for ventricular fibrillation, this rhythm 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? V fib<\/p>\n\n\n\n
Administer 3 sequential (stacked) shocks at 360 J (monophasic defibrillator)
Give amiodarone 300 mg IV\/IO
Give epinephrine 1 mg IV\/IO
Intubate and administer 100% oxygen
Give epinephrine 1 mg IV\/IO<\/p>\n\n\n\n
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? vfib<\/p>\n\n\n\n
Atropine 0.5 mg IV
Epinephrine 1 mg IV
Endotracheal intubation
Transcutaneous pacing
Epinephrine 1 mg IV<\/p>\n\n\n\n
What is the recommended depth of chest compressions for an adult victim?<\/p>\n\n\n\n
At least 1.5 inches
At least 2 inches
At least 2.5 inches
At least 3 inches
At least 2 inches<\/p>\n\n\n\n
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. 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? PEA<\/p>\n\n\n\n
Atropine 1 mg
Dopamine at 10 to 20 mcg\/kg per minute
Epinephrine 1 mg
Intubation and administration of 100% oxygen
Epinephrine 1 mg<\/p>\n\n\n\n
Your patient is not responsive and is not breathing. You can palpate a carotid pulse. Which action do you take next?<\/p>\n\n\n\n
Apply an AED
Obtain a 12-lead ECG
Start an IV
Start rescue breathing
Start rescue breathing<\/p>\n\n\n\n
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 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? ST Elevation<\/p>\n\n\n\n
Application of transcutaneous pacemaker
Atropine administration
Nitroglycerin administration
Reperfusion therapy
Reperfusion therapy<\/p>\n\n\n\n
You are providing bag-mask ventilations to a patient in respiratory arrest. How often should you provide ventilations?<\/p>\n\n\n\n
About every 5-6 seconds
About every 8-10 seconds
About every 12-14 seconds
About every 17-18 seconds
About every 5-6 seconds<\/p>\n\n\n\n
Which action is likely to cause air to enter the victim’s stomach (gastric inflation) during bag-mask ventilation?<\/p>\n\n\n\n
Giving breaths over 1 second
Ventilating too quickly
Providing a good seal between the face and the mask
Providing just enough volume for the chest to rise
Ventilating too quickly<\/p>\n\n\n\n
A patient was in refractory ventricular fibrillation. A third shock has just been administered. Your team looks to you for instructions. What is your next action?
