1. A patient is admitted to the hospital with confusion, memory loss, and ataxia. What other information would lead you to suspect that his symptoms may be caused by secondary thiamin deficiency?

ANS:  B

Alcoholism may be associated with a secondary thiamin deficiency because the liver needs increased amounts of thiamin to detoxify alcohol. Limited food intake may cause primary deficiency (although legumes are a good source of thiamin, and so primary deficiency is unlikely). Strokes and Alzheimer’s disease may cause confusion, memory loss, and ataxia, but not in relation to a secondary vitamin deficiency.

ANS:  C

The best way to ensure intake of a variety of phytochemicals is to eat a variety of plant-based foods, including whole grains, fruits, and vegetables. Multivitamin supplements do not necessarily contain phytochemicals. Soy-based foods contain only a limited selection of phytochemicals. Dairy products do not contain phytochemicals; herbs and spices may provide some but are used in small quantities and so would not provide significant amounts.
