Accepted Answer

Dietary fats or lipids are crucial for several reasons: A) They serve as a concentrated source of energy and provide essential fatty acids that the body cannot synthesize on its own. B) Fats play a significant role in maintaining healthy skin by supporting cell structure and integrity. E) Fats are also necessary for the absorption of fat-soluble vitamins (A, D, E, and K), which are vital for various bodily functions including vision, bone health, and blood coagulation.

Question 2

A nursing instructor teaches a group of nursing students that the functions of protein include which of the following?

Accepted Answer

The answer of A nursing instructor teaches a group of...

Question 3

A dietician explains that a rapid increase in the blood glucose level that stimulates the pancreas to produce more insulin, which rapidly decreases blood glucose and increases appetite, is caused by the ingestion of

Accepted Answer

The ingestion of simple carbohydrates can quickly increase blood glucose levels, causing the pancreas to produce more insulin. This rapid decrease in blood glucose levels can stimulate appetite. Saturated fats and proteins do not have the same effect on blood glucose levels. Complex carbohydrates can also cause an increase in blood glucose levels, but the increase is typically slower and sustained over a longer period of time compared to simple carbohydrates.

Question 4

A nurse educates a patient about digestion. The nurse explains to the patient that digestive enzymes are released from which of the following organs?

Accepted Answer

The answer of A nurse educates a patient about digestion....

Question 5

A dietician teaches a group of student nurses about different types of fat. The dietician says the type of fats that primarily come from animal sources, are solid at room temperature, and are implicated in cardiovascular disease because they increase blood cholesterol are known as

Accepted Answer

The description given matches that of saturated fats, which are mostly derived from animal sources and are solid at room temperature. Saturated fats have been linked to an increased risk of cardiovascular disease as they can increase blood cholesterol levels. Monounsaturated and polyunsaturated fats are typically liquid at room temperature and have been shown to have health benefits when consumed in moderation. Trans fats are mostly found in processed foods and are also linked to an increased risk of cardiovascular disease.

Question 6

A nurse explains to a vegetarian that he or she must be careful to ingest a greater amount of beans, dried fruit, whole grains, and molasses to prevent

Accepted Answer

Vegetarians are at a higher risk of developing iron deficiency due to the lack of heme iron found in meat. Beans, dried fruit, whole grains, and molasses are good plant-based sources of iron.

Question 7

A dietician explains that insoluble fiber is not digested, but passes through the intestines, acting like a bulk laxative and drawing water into the intestines, helping to prevent constipation. A good source of insoluble fiber would be

Accepted Answer

The answer of A dietician explains that insoluble fiber is...

Question 8

A dietician teaches a group of student nurses that water-soluble vitamins cannot be stored in the body. Some are lost in the urine, making it necessary to consume them on a daily basis. The dietician says one example of a water-soluble vitamin is

Accepted Answer

The dietician states that water-soluble vitamins cannot be stored in the body and are lost in the urine, requiring daily consumption. Vitamin C is an example of a water-soluble vitamin. Vitamin A, D, and E are all fat-soluble vitamins and can be stored in the body.

Question 9

A dietician teaches that minerals are inorganic compounds used by all body tissues for numerous functions except

Accepted Answer

Minerals do not directly aid in the absorption of fat-soluble vitamins, although their presence can improve the absorption process. Instead, minerals have a variety of other functions in the body, including forming the structure of bones and teeth, aiding in muscle contraction, and assisting in water metabolism.

Question 10

A dietician teaches a group of student nurses that omega-3 and omega-6 fatty acids are found in walnuts, flaxseed, and several types of fatty fish, and are essential for normal cell development. The dietician says these types of fats are known as

Accepted Answer

Omega-3 and omega-6 fatty acids are types of polyunsaturated fats that are essential for normal cell development. Trans fats are harmful and should be avoided, while monounsaturated and saturated fats have health benefits but are not considered essential.

Question 11

An instructor is explaining the functions, sources, and intake recommendations for vitamins. The instructor realizes additional instruction is required when a student says:

Accepted Answer

Fat-soluble vitamins do not serve as coenzymes for metabolism; rather, they play roles in vision, blood clotting, antioxidant activity, and bone health. Water-soluble vitamins typically serve as coenzymes in metabolic processes.

Question 12

A homeless man is admitted to the hospital with severe emaciation, a swollen abdomen, lethargy, and skin infections. The patient is diagnosed with a disease known as kwashiorkor, a condition caused by

Accepted Answer

Kwashiorkor is caused by a lack of adequate protein in the diet. This results in edema, or swelling due to fluid build-up in the tissues, particularly in the abdomen. The other options listed are not associated with this condition.

Accepted Answer

Adequate levels of fiber can decrease LDL cholesterol and increase HDL cholesterol, leading to improved cardiovascular health.
