1. The primary responsibility for nutrition care of people in the community belongs to the:

A. community physician.
B. public health nurse.
C. public health nutritionist.
D. registered dietitian.

Correct answer: C

Rationale: Public health nutritionists work within communities to ensure that populations have access to nutritional resources. They focus on promoting good nutrition, developing programs, and educating the public about healthy eating habits. While community physicians, public health nurses, and registered dietitians may also play roles in promoting nutrition in the community, the primary responsibility for nutrition care typically falls under the purview of public health nutritionists.

2. Which lipoprotein increases the risk of cardiovascular disease?

A. Low-density lipoprotein (LDL)
B. High-density lipoprotein (HDL)
C. Very low-density lipoprotein (VLDL)
D. Chylomicrons

Correct answer: A

Rationale: The correct answer is A: Low-density lipoprotein (LDL). LDL is often referred to as 'bad cholesterol' because it can lead to plaque buildup in arteries, increasing the risk of cardiovascular disease. High-density lipoprotein (HDL) is considered 'good cholesterol' as it helps remove LDL from the arteries, reducing the risk of cardiovascular issues. Very low-density lipoprotein (VLDL) and chylomicrons are also lipoproteins that transport fats in the bloodstream, but they are not as strongly associated with an increased risk of cardiovascular disease as LDL.

3. Which monosaccharide only occurs naturally in foods in combination with another sugar as a disaccharide?

A. Fructose.
B. Galactose.
C. Sucrose.
D. Maltose.

Correct answer: B

Rationale: The correct answer is B, galactose. Galactose naturally occurs in foods only when it is combined with glucose to form lactose, a disaccharide found in milk. Fructose is a monosaccharide found in fruits and honey. Sucrose is a disaccharide composed of glucose and fructose, commonly known as table sugar. Maltose is a disaccharide formed by the combination of two glucose molecules.

4. The release of gastric secretions is stimulated by nerve and hormonal stimuli and the:

A. ingestion of water.
B. swallowing reflex.
C. presence of food in the stomach.
D. closing of the pyloric sphincter.

Correct answer: C

Rationale: The correct answer is C: 'presence of food in the stomach.' Gastric secretions are stimulated when food enters the stomach, triggering nerve and hormonal responses. This process prepares the stomach for digestion. Choices A, B, and D are incorrect because ingesting water, swallowing reflex, and the closing of the pyloric sphincter do not directly stimulate the release of gastric secretions.

5. What is the primary function of protein in the body?

A. Provide energy.
B. Regulate metabolic processes.
C. Control muscle contractions.
D. Build tissue.

Correct answer: D

Rationale: The primary function of protein in the body is to build and repair tissues. Proteins are crucial for growth, maintenance, and repair of body tissues, including muscles, organs, and skin. While proteins can be a source of energy, their primary role is not to supply energy. Regulating metabolic processes and controlling muscle contractions are functions typically attributed to other nutrients and compounds in the body, such as vitamins and minerals.
