  6. B or D. They both look right..

  7. D

  8. D-take asprin before niacin

  9. Answer D: Patients almost always have flushing associated with Niacin intake, reason being the receptor that causes the reduction in lipids is also the same receptor that causes flushing but by targeting COX through aspirin can reduce flushing symptoms big time. As COX is upstream of PGD2, NSAIDs have the ability to block production of PGD2, PGE2 and PGI2 the likely culprits.

    Counseling should be done in terms of health benefits of niacin and for the next dose of niacin the patient should take aspirin 30 minutes before giving him an extended release niacin.
