1. Give aspirin 160 to 325 mg chewed immediately. - 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.

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. - 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.

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?

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 - 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
