Question 1
41% answer correctly
The patient was admitted to the general medical unit with a history of alcoholism. A is in progress and he has recurrent episodes of this rhythm. You review his chart. Notes about the 12-lead ECG say that his baseline QT-interval is top normal to slightly prolonged. He has received 2 doses of epinephrine 1 mg and 1 dose of amiodarone 300 mg IV so far. For his next medication you would now order:
give magnesium sulfate 1 to 2 g IV diluted in 10 mL D5W given over 10 -20 mins.
lidocaine 1 to 1.5 mg IV and start infusion 2 mg/minute
repeat amiodarone 300 mg IV
give sodium bicarb 50 mEq IV
repeat amiodarone 150 mg IV
Question 2
83% answer correctly
Following initiation of CPR and one shock for VF, this rhythm is present on the next rhythm check. A second shock is given and chest compressions are immediately resumed. An IV is in place and no drugs have been given. Bag-mask ventilations are producing visible chest rise. What is your next order?
prepare to give epinephrine 1 mg IV
perform endotracheal intubation; administer 100 % oxygen
prepare to give amiodarone 300 mg IV
administer 3 sequential (stacked) shocks at 360J (monophasic defibrillator)
administer 3 sequential (stacked) shocks at 200J (biphasic defibrillator)
Question 3
27% answer correctly
A patient has been resuscitated from cardiac arrest and is being prepared for transport. She is intubated and is receiving 100% oxygen. During the resuscitation she received 2 doses of epinephrine 1 mg, atropine 1 mg, and lidocaine 100 mg IV. You now observe the above rhythm on the cardiac monitor. The rhythm abnormally is becoming more frequent and increasing in number. You should order:
give amiodarone 150 mg IV, start infusion
give lidocaine 1- 1.5 mg IV
give amiodarone 300 mg IV, start infusion
give lidocaine 0.5-0.75 mg/kg IV, start lidocaine infusion
repeat epinephrine 1 mg IV
