A.  Usually affects the aortic arch and the great vessels
B.  Treated with corticosteroids
C.  Surgery is almost always necessary

Answer 44

44.  Choice C is the correct answer.  The anterior leads V3 and V4, and the lateral leads I, avL, V5, and V6 exhibit   ST elevation.  ST elevation is also seen in one of the septal leads lead V2.  There is no ST depression in these leads so there is no ischemia, just infarction.


Question 44

44.  Your patient is a 46 year old with chest pain.  Below is his EKG.  Which of the following is the correct diagnosis?



A.  Posterior Wall MI
B.  Anteriolateral ischemia
C.  Anteriolateral MI

Answer 43

43.  Choice A is the correct answer.  NSTEMI's are also none as non Q wave MI have a higher mortality rate.  They usually do not have occlusion of the related coronary artery.  The infarction does not go all the way through the wall.  These are medically treated with beta blockers, nitrates, morphine, oxygen, and ASA.  ACE inhibitors are helpful for those with decreased ejection fraction.



Question 43

43.  Which of the following is not true of a non ST elevation MI (NSTEMI)?

A.  They have a lower mortality rate than STEMI's
B.  They have a higher mortality rate than STEMI's
C.  They have elevated Troponin without any ST elevation on the EKG
D.  Medical management includes beta blockers, nitrates, morphine, oxygen, and ASA

Answer 42

42.  Choice C is the correct answer.  Hydralazine is safe in pregnancy and works great in this situation. The patients HR is too low to increase the dose of labetolol which would be ideal.  Delivery is recommended in severe preclampsia but not pregnancy induced hypertension.  In addition, the patient is only 22 weeks and is not viable.  ACE inhibitors should be avoided late in pregnancy due to increasing prostaglandin levels.
