Answer to Question 1

ANS: A
Many foods interfere with iron absorption and should be avoided when the iron is consumed. These foods include phosphates found in milk, phytates found in cereals, and oxalates found in many vegetables. Multivitamins may contain iron; no contraindication exists to taking the two together. Vitamin Ccontaining juices enhance the absorption of iron. Meat, fish, and poultry do not have an effect on absorption.

Answer to Question 2

ANS: C
Hypervitaminosis of vitamin D presents the greatest problem because this fat-soluble vitamin is stored in the body. Vitamin D is the most likely of all vitamins to cause toxic reactions in relatively small overdoses. The water-soluble vitamins, primarily niacin, B6, and C, can also cause toxicity but not at the low dose that occurs with vitamin D.
