ACLS PreTest: Pharmacology and Practical Application Part 2 Complete Review 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. Which drug should be administered? - Adenosine 6mg A 35-year-old woman presents with a chief complaint of palpitations. She has no chest discomfort, shortness of breath, or light-headedness. Her blood pressure is 120/78 mm Hg. Which intervention is indicated first?SVT Adenosine 3 mg IV bolus Adenosine 12 mg IV slow push (over 1 to 2 minutes)Metoprolol 5 mg IV and repeat if necessary Vagal maneuvers - Vagal maneuvers A 35-year-old woman presents with a chief complaint of palpitations. She has no chest discomfort, shortness of breath, or light-headedness. Her blood pressure is 120/78mm Hg. Which intervention is indicated first? - Vagal maneuvers 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 Administer adenosine 12 mg IV Perform unsynchronized cardioversion Perform vagal maneuvers Perform synchronized cardioversion - Administer adenosine 12 mg IV A 45-year-old woman with a history of palpitations develops light-headedness and palpitations. She has received adensoine 6mg IV for the rhythm shown here, without conversion of the rhythm. She is now extremely apprehensive. Her blood pressure si 128/70mm Hg. What is the next appropriate intervention? - Administer adenosine 12 mg IV A 57-year-old woman has palpitation, chest discomfort, and tachycardia. The monitor shows a regular wide-QRS at a rate of 180/min. She becomes diaphoretic, and her blood pressure is 80/60 mm HG/ Which action do you take next? - Perform electrical cordioversion A 57-year-old woman has palpitations, chest discomfort, and tachycardia. The monitor shows a regular wide-complex QRS at a rate of 180/min. She becomes diaphoretic, and her blood pressure is 80/60 mm Hg. Which action do you take next? Establish IV access Obtain a 12-lead ECG Perform electrical cardioversion Seek expert consultation - Perform electrical cardioversion A 62-year-old man suddenly experienced difficulty speaking and left-sided weakness. He meets initial criteria for fibrinolytic therapy, and a CT scan of the brain is ordered. Which best describes the guidelines for antiplatelet and fibrinolytic therapy? Give aspirin 160 to 325 mg to be chewed immediately Give aspirin 160 mg and clopidogrel 75 mg orally Give heparin if the CT scan is negative for hemorrhage Hold aspirin for at least 24 hours if rtPA is administered - Hold aspirin for at least 24 hours if rtPA is administered A 62-year-old man suddenly experienced difficulty speaking and left-sided weakness. He meets initial criteria for fibrinolytic therapy, and a CT scan of the brain si ordered. Which best describes the guidelines for antiplatelet and fibrinolytic therapy? - Hold aspirin for at least 24 hours if rtPA is administered A monitored patient in the ICU developed a sudden onset of narrow-complex tachycardia at a rate of 220/min. The patient's blood pressure is 128/58 mm Hg, the PETCO2 is 38 mm Hg, and the pulse oximetry reading is 98%. There is vascular access in the left arm, and the patient has not been given any vasoactive drugs. A 12-lead ECG confirms a supraventricular tachycardia with no evidence of ischemia or infarction. The heart rate has not responded to vagal maneuvers. What is your next action? Administer adenosine 6 mg IV push Administer amiodarone 300 mg IV push Perform synchronized cardioversion at 50 J Perform synchronized cardioversion at 200 J - Administer adenosine 6 mg IV push
