Congestive Heart Failure And Angina Pectoris! Quiz - Quiz

What do you know about congestive heart failure and angina pectoris? Could you pass this quiz? Congestive heart failure ensues when your heart muscles do not pump blood as well as they should. Angina is a disorder marked by severe pain in the chest, but it is not a heart attack. Take this quiz and learn more about congestive heart failure and angina.


Questions and Answers
  • 1. 
    What are the causes of CHF?
    • A. 

      Disease of the myocardium; circulatory factors

    • B. 

      Atherosclerosis; myocardial infarction

    • C. 

      Unidrectional block; decreased conductivity of Purkunje fibres

  • 2. 
    What are the compensatory mechanisms in response to CHF?
    • A. 

      Decreased sympathetic tone; RAAS activation; decreased body fluid volume

    • B. 

      Increased sympathetic tone; RAAS deactivation; decreased body fluid volume

    • C. 

      Increased sympathetic tone; RAAS activation; increased body fluid volume

  • 3. 
    What are the effects of cardiac glycosides?
    • A. 

      Bind to Na binding site on Na/K exchanger; decreased C/Na exchange; increase Ca levels; increased contractility

    • B. 

      Bind to K binding site on Na/K exchanger; decreased C/Na exchange; increase Ca levels; decreased contractility

    • C. 

      Bind to Na binding site on Ca/Na exchanger; decreased Ca/Na exchange; decrease Ca levels; decreased contractility

  • 4. 
    What causes unstable angina?
    • A. 

      Atherosclerosis which ruptures, thrombus forms on top, often leading to complete occlusion

    • B. 

      Atherosclerosis which reduces O2 to tissue

    • C. 

      Atherosclerosis which ruptures, thrombus forms on top, always followed by breaking up and embolus formation leading to complete occlusion and infarction

  • 5. 
    What are the drug therapy targets for angina treatment?
    • A. 

      Decrease heart rate; increase activation of RAAS system

    • B. 

      Increase cardiac output; decrease body fluid volume

    • C. 

      Improve myocardial perfusion; reduce metabolic demand

  • 6. 
    What are the effects of organic nitrates?
    • A. 

      Vasodilation; dilation of large veins results in decreased after-load and decreased cardiac output

    • B. 

      Vasodilation; dilation of large veins results in decreased pre-load and decreased cardiac output

    • C. 

      Vasodilation; dilation of large veins results in decreased pre-load and decreased blood pressure

  • 7. 
    What is the mechanism by which organic nitrates exert their effects?
    • A. 

      Increased PKG which causes relaxation of smooth muscle

    • B. 

      Increased PKG which causes relaxation of large veins and arteries

    • C. 

      Decreased PKG which causes relaxation of smooth muscle

  • 8. 
    What are the anti-anginal actions of organic nitrates?
    • A. 

      Increase O2 consumption; redistribution of coronary flow to infarct areas; relief of coronary spasm; improve perfusion to other organs

    • B. 

      Decrease O2 consumption; redistribution of coronary flow to ischemic areas; relief of coronary spasm; improve perfusion

    • C. 

      Decrease O2 consumption; redistribution of coronary flow to infarct areas; relief of coronary spasm; improve perfusion
