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. 3. Give normal saline bolus 250 mL to 500 mL. 4. Start epinephrine 2 to 10 mcg/min. 1. Do not give aspirin for at least 24 hours if rtPA is administered. - correct answer A 62-year-old man suddenly experienced difficulty speaking and left-side weakness. He was brought to the emergency department. He meets initial criteria for fibrinolytic therapy, and a CT scan of the brain is ordered. What are the guidelines for antiplatelet and fibrinolytic therapy? 1. Do not give aspirin for at least 24 hours if rtPA is administered. 2. Give aspirin 160 mg and clopidogrel 75 mg orally. 3. Administer heparin if CT scan is negative for hemorrhage. 4. Administer aspirin 160 to 325 mg chewed immediately. 4. Use of a phosphodiesterase inhibitor within 12 hours - correct answer A patient with possible ST-segment elevation MI has ongoing chest discomfort. Which of the following would be a contraindication to the administration of nitrates? 1. Heart rate 90/min. 2. Left ventricular infarct with bilateral rales. 3. Blood pressure greater than 180 mm Hg. 4. Use of a phosphodiesterase inhibitor within 12 hours 1. Epinephrine 1 mg - correct answer A patient is in cardiac arrest. Ventricular fibrillation has been refractory to a second shock. Of the following, which drug and dose should be administered first by the IV/IO route? 1. Epinephrine 1 mg 2. Vasopressin 20 units 3. Sodium bicarbonate 50 mEq 4. Atropine 1 mg 2. Adenosine 6 mg - correct answer A 35-year-old woman has palpitations, light-headedness, and a stable tachycardia. The monitor shows a regular narrow-complex QRS at a rate of 180/min. Vagal maneuvers have not been effective in terminating the rhythm. An IV has been established. What drug should be administered IV? 1. Lidocaine 1mg/kg 2. Adenosine 6 mg 3. Epinephrine 2 to 10 mcg/kg per minute 4. Atropine 0.5 mg
