2˚ AV block (Mobitz type II)
no p-r prolonged, random drops - correct answer. Identify the rhythm.
Sinus bradycardia - correct answer. Identify the rhythm.
Atrial flutter - correct answer. Identify the rhythm.

Fine ventricular fibrillation - correct answer. Identify the rhythm.
2˚ AV block
(Mobitz type I Wenchkebach) - correct answer. Identify the rhythm.

2. Magnesium is indicated for VF/pulseless VT associated with torsades de pointes. -
correct answer. Which of the following statements about the use of magnesium in
cardiac arrest is most accurate?
1. Magnesium is indicated for shock-refractory monomorphic VT.
2. Magnesium is indicated for VF/pulseless VT associated with torsades de pointes.
3. Magnesium is contraindicated for VT associated with a normal QT interval.
4. Magnesium is indicated for VF refractory to shock and amiodarone or lidocaine.
1. Give aspirin 160 to 325 mg chewed immediately. - correct answer. A patient with ST-
segment elevation MI has ongoing chest discomfort. Fibrinolytic therapy has been
ordered. Heparin 4000 units IV bolus was administered, and a heparin infusion of 1000
units per hour is being administered. Aspirin was not taken by the patient because he
had a history of gastritis treated 5 years ago. Your next action is to:
1. Give aspirin 160 to 325 mg chewed immediately.
2. Give 75 mg enteric-coated aspirin orally.
3. Give 325 mg enteric-coated aspirin rectally.
4. Substitute clopidogrel 300 mg loading dose.
4. Start epinephrine 2 to 10 mcg/min. - correct answer. A patient has sinus bradycardia
with a heart rate of 36/min. Atropine has been administered to a total of 3 mg. A
transcutaneous pacemaker has failed to capture. The patient is confused, and her blood
pressure is 110/60 mm Hg. Which of the following is now indicated?
1. Give additional 1 mg atropine.
2. Start dopamine 10 to 20 mcg/kg per minute.
