A client asks for a simple explanation of the difference between fat-soluble and water-soluble vitamins. The nurse explains the main difference by stating:
1. "Water-soluble vitamins are readily available in foods and fat-soluble vitamins are not as available.".
2. "The body has greater need for water-soluble vitamins than fat-soluble vitamins.".
3. "Fat-soluble vitamins can be stored by the body and water-soluble vitamins are not stored.".
4. "Fat-soluble tend to be found in meat and dairy products and water-soluble vitamins are found in carbohydrates.".

Rationale: Fat-soluble vitamins are stored in the liver and can become toxic if consumed in excess. Water-soluble vitamins are not stored and the excess in excreted on a daily basis. All vitamins are readily available in foods and are needed by the body. Different foods have varying amounts of each vitamin; therefore a diet that has balance, variety, and moderation will meet vitamin needs.
