Question 1

Which of the following is the recommended percentage of total daily fat calories of an average person?

Accepted Answer

The recommended percentage of total daily calories from fat for an average person is about 25-30%. This guideline helps ensure a balanced diet that supports overall health while providing enough energy and essential fatty acids.

Question 2

Which of the following may be caused by a deficiency of vitamin B12?

Accepted Answer

Pernicious anemia is a type of anemia that occurs when the body cannot absorb vitamin B12 properly, which can lead to a deficiency. Vitamin B12 is necessary for the production of healthy red blood cells, and a deficiency can cause anemia, fatigue, and weakness. Weight loss, diarrhea, nervousness, and headaches are not typically associated with a deficiency of vitamin B12.

Question 3

Which of the following best describes a stage of life when there is a decreased need for calories because of general decline in physical activity?

Accepted Answer

Elderly individuals generally experience a decline in physical activity and muscle mass, and thus have a decreased need for calories compared to younger individuals. Pregnancy, infancy, and adolescence are all stages of life with increased calorie needs due to growth and development.

Question 4

Which of the following terms is used to describe the physical and chemical changes to food that the body makes?

Accepted Answer

Digestion refers to the process of breaking down food into smaller components that can be absorbed into the bloodstream.

Question 5

Which of the following is the most rapidly absorbed form of carbohydrate?

Accepted Answer

Monosaccharides are the simplest form of carbohydrates and can be quickly absorbed by the body without any digestion necessary. Examples of monosaccharides include glucose, fructose, and galactose.

Question 6

Which of the following are minerals that become ionized and carry a positive or negative charge?

Accepted Answer

Electrolytes are minerals that become ionized and carry a positive or negative charge. They play important roles in regulating fluid balance, nerve and muscle function, pH balance, and many other physiological processes in the body. Catalysts and coenzymes are not minerals, and while water-soluble minerals can dissolve in water, they may not necessarily carry a charge.

Question 7

Which of the following is the nutrient used as building components of body proteins and as the basic structural unit in all body tissues and cells?

Accepted Answer

Amino acids are the building blocks of proteins and are used to create and maintain body tissues and cells.

Question 8

Which of the following is NOT considered a classification of nutrients?

Accepted Answer

Preservatives are not considered a classification of nutrients as they are used to prevent food spoilage and degradation rather than providing any nutritional value to the body. The other options (water, fats, vitamins, and proteins) are all considered essential nutrients that provide various functions and benefits to the body.

Question 9

Which of the following statement is most correct concerning weight control?

Accepted Answer

Weight is a highly individualized matter and varies based on factors such as height, body composition, and genetics. Therefore, there is no one ideal weight for the entire population, but there is an ideal weight range for each individual. Charts may give ranges, but they are only general guidelines and not always accurate. Lastly, while it is true that individuals will gain weight if they consume more calories than they expend, this only applies to weight gain and not necessarily weight control - which can include maintaining or losing weight.

Question 10

Which of the following is true regarding vitamins?

Accepted Answer

Vitamins B and C are water soluble, meaning they dissolve in water and are not stored in the body for any length of time.

Answer: B 
 Vitamins A, B, D, and E are fat soluble, meaning they dissolve in fat and are stored in the body's fatty tissues.

Answer: A, D, and E are incorrect.
 Vitamins are needed in small quantities, and water-soluble vitamins (such as vitamins B and C) are not stored in fatty tissues. Finally, vitamins are not simple molecules, as they often have complex structures and functionalities.

Question 11

Which of the following is the most important recommendation when you encourage patients to read and evaluate food labels?

Accepted Answer

The most important recommendation when encouraging patients to read and evaluate food labels is to check the calories from fat, not more than 30 percent of total calories. This is because a high intake of fat, especially saturated and trans fats can increase the risk of heart disease, stroke, and other health problems. By reading food labels, patients can make informed choices about the fat content of the foods they consume and make adjustments to their diet if necessary.

Question 12

Which of the following best classifies most dietary fiber?

Accepted Answer

Dietary fiber is a type of carbohydrate found in plant-based foods such as fruits, vegetables, whole grains, and legumes.

Question 13

Which of the following statements is false regarding digestion?

Accepted Answer

The entire process of digestion does not take place in the stomach. It involves different organs such as the mouth, esophagus, stomach, small intestine, and large intestine. Each organ plays a unique role in breaking down food and absorbing nutrients.

Question 14

Which of the following best describes a stage of life in which individuals experience the greatest levels of growth and the need for total nutrients is greater at this stage?

Accepted Answer

Adolescence is a stage of life in which individuals experience the greatest levels of growth and the need for total nutrients is greater at this stage.

Question 15

In cancer patients receiving treatment, increased nutrients are needed for repair and replacement of the lost cells.Which nutrient level in particular needs to be increased?

Accepted Answer

Cancer patients receiving treatment require increased protein intake to support the repair and replacement of cells. Proteins are essential for tissue growth, cell division, and repairing damaged tissues. Carbohydrates, fibers, lipids, and minerals are also important nutrients, but their increased intake may not be as critical as proteins in these patients.

Question 16

Which of the following is NOT an example of a B-complex vitamin?

Accepted Answer

Cholecalciferol, also known as vitamin D, is not a B-complex vitamin. The B-complex vitamins include thiamine, riboflavin, niacin, and folic acid, among others.

Question 17

Which of the following is the main function of protein?

Accepted Answer

The main function of protein is to provide amino acids, which are essential for building and repairing tissues, as well as for the production of enzymes and hormones. Protein can also be used for energy, but this is not its primary function. Maintaining heat and fluid balance are not functions of protein.

Question 18

A patient who is obese has a total body weight that is what percentage greater than their ideal weight?

Accepted Answer

Obesity is generally defined as a total body weight that is 20% or more above the individual's ideal body weight.

Question 19

Which of the following best describes the action of the two minerals sodium and potassium?

Accepted Answer

Sodium and potassium are both electrolytes, meaning they conduct electrical charges in the body and are crucial for maintaining proper fluid balance, nerve function, and muscle function.

Question 20

Which of the following includes lignin, cellulose, gums, and pectins?
