Answer 15

15.  Choice A is the correct answer.  Dilated cardiomyopathy causes systolic dysfunction.  It can effect one or both ventricles.  Presents with symptoms similar to CHF.  Hypertrophic cardiomyopathy is a diastolic problems with small chambers and causes outflow obstruction.  It can present with chest pain or dyspnea on exertion.  Restrictive cardiomyopathy is a diastolic problem with elevated right heart pressures.  Amyloidosis is the most common cause or restrictive cardiomyopathy.



Question 15

15.  Which of the following cardiomyopathies are characterized by systolic dysfunction?

A.  Dilated Cardiomyopathy
B.  Hypertrophic Cardiomyopathy
C.  Restrictive Cardiomyopathy
D.  Post Partum Cardiomyopathy




Answer 14

14.  Choice B is the correct answer.  This is a first degree AV Block.  This is characterized by a long PR interval over 0.2.  There are no dropped QRS complexes.  Pacemaker insertion is appropriate for third degree AV block.  Digoxin is used for rate control with atrial fib and also for patients who need inatropic support with there ejection fraction.  Defibrillation is appropriate for ventricular tachycardia, ventricular fibrillation, and unstable narrow complex tachycardia.



Question 14

14.  Which of the following is the best management option for the rhythm listed below?


A.  Arrange for immediate pacemaker
B.  Observation
C.  Start the patient on digoxin
D.  Defibrillation


Answer 13

13.  Choice D is the correct and answer.  This is demonstrated by ST elevation in the inferior leads, II, III, and aVf.  There is also reciprocal changes seen laterally in some of the lateral leads I and avL.  There is no ST depression in the inferior leads so C is incorrect.  Anteriorly V1-V4 there is just really some ischemic changes.  Laterally there is just ST depression in some of the leads which is the reciprocal changes.  

Question 13

 13.  What is the diagnosis of the EKG listed below:


  1. Lateral Wall MI
  2. Anterior Wall MI
  3. Inferior Wall Ischemia
  4. Inferior Wall Infarction

Answer 12

12.   Choice C is the correct answer.  Indomethacin causes vasoconstriction and can cause a patent ductus to close.  Sometimes in some clinical situations it is desired to keep the ductus arteriosis patent and prostaglandin infusion is appropriate for that.  Nitroglycerin and balloon vulvuloplasty are not options.
