    Elevated Lp(a) presents a far greater risk than elevated LDL because it is both atherogenic and thrombogenic

      True

    • B. 

      False

  • 9. 
    In unhealthy lipoprotein metabolism (unhealthy eating), more particles are created than the body can use and remove, causing a greater particle load to progress through the metabolic pathway, with the particles getting progressively more cholesterol-rich throughout the process. This leads to an increased number of particles that are high in cholesterol, thus increasing the patient’s risk for atherosclerosis.

      True

    • B. 

      False

  • 10. 
    Which of the following statements are true regarding lipoprotein particles and atherosclerosis?

      Smaller particles more easily infiltrate the vessel wall, initiating the atherosclerotic process

    • B. 

      More particles means more opportunity for infiltration to occur.

    • C. 

      Higher cholesterol content can result in a more rapid advancement in atherosclerosis.

    • D. 

      All of the above are true

  • 11.

      False

  • 12.
