Twelve-Lead Electrocardiography phần 9

2. Bước thủ tục tiếp theo của bạn sẽ là: a) quản lý nitroglycerin 0,4 mg ngậm dưới lưỡi. b) quản lý furosemide 80 mg IV. c) thực hiện một điện tâm đồ 12 đạo trình. d) quản lý lidocaine 75 mg IV. e) | 136 Chapter 14 Case Presentations 2. Your next procedural step would be to a administer nitroglycerin sublingually. b administer furosemide 80 mg IV. c perform a 12-lead ECG. d administer lidocaine 75mg IV. e administer a unit dose of nebulized albuterol sulfate. f start another twin-cath IV. g administer 325mg aspirin. 3. Your next procedural step would be to a administer nitroglycerin sublingually. b administer furosemide 80mg IV. c perform a 12-lead electrocardiogram. d administer lidocaine 75mg IV. e administer a unit dose of nebulized albuterol sulfate. f start another twin-cath IV. g administer 325mg aspirin. While performing the above procedures you are able to elicit no further history that would contraindicate thrombolytic therapy. An ECG has been performed and is now available to you as appears in Figure . 4. On the basis of currently available information you conclude that thrombolytic agents if they were to be needed would be a absolutely contraindicated. b relatively contraindicated. c not contraindicated. 5. Upon completion of the ECG you quickly note that the patient s electrocardiogram shows Figure . Answers and Case Discussion 137 a a normal axis. b RAD. c LAD. d an indeterminate axis. 6. Upon further examination of the ECG you conclude that it shows a acute inferior STEMI b acute anterior STEMI c inferior myocardial infarction that may be old d anterior myocardial infarction that may be old e benign early repolarization changes f LBBB simulating anterior myocardial infarction g acute pericarditis h normal ECG i nonspecific ST changes 7. Your partner has established contact with medical command. Your field assessment as reported to the command physician is that a sufficient evidence of STEMI exists to recommend thrombolytic therapy and to institute the prehospital thrombolytic protocol. b evidence of STEMI exists but absolute contraindications prohibit thrombolytic therapy. c evidence of STEMI exists but relative .
