20.  Choice A is the correct answer.  This patient has the typical ST depression in the septal leads V1 and V2.  This patient is also has ST elevation in the inferior leads (II, III, and aVf) suggestive of an inferior wall MI.  There is no ST depression in the lateral leads (I, avL, V5 and V6)

Answer 19

19.  Choice D is the correct answer.  Dihydropyridines dilate arterioles only (Nifedipine, Amlodipine, and Felodipine) and Non Dihydropyridines slow calcium channels in the heart and dilates arterioles (verapamil and diltazem).

Question 19

19.  What is the difference between dihydropyridines and nondihydropyridines?

A.  Dihydropyridines slow down calcium channels in the heart and nondihydropyridines do not

B.  Dihydropyridines constrict arterioles

C.  Both dihydropyridines dilate arterioles and nondihydropyridines constrict arterioles

D.  Nondihydropyridines slow calcium channels in the heart and dilate arterioles

Answer 18

18.  Choice B is the correct answer.  Patients with ACE inhibitor induced angioedema are typically deficient in C1 Esterase.  Treatment involves Fresh Frozen Plasma.  Corticosteroids and antihistamines should be administered also.  Patients with airway issues should be intubated until this can be treated.  Prostaglandins and bradykinnin are increased in patients taking ACE inhibitors.  TNF has nothing to do with this disease process.

Question 18

18.  Your patient is a 45 year old male that presents with the swelling below.  He has been taking lisinopril for hypertension.  Which of the following enzymes deficiency is likely responsible for the swelling?
