1. What is the factor most likely to stimulate digestive secretions?

• A. Smelling or seeing food
• B. Grocery shopping
• C. Fasting
• D. Exercise

Correct answer: A

Rationale: The correct answer is A: Smelling or seeing food. When an individual smells or sees food, it can trigger the body to start producing digestive secretions in anticipation of food consumption. This physiological response helps prepare the digestive system for the incoming meal. Choices B, C, and D are incorrect because grocery shopping, fasting, and exercise do not directly stimulate digestive secretions in the same way that the sight or smell of food does.

2. Cholecystokinin (CCK) is produced in the:

• A. duodenum.
• B. stomach.
• C. pancreas.
• D. liver.

Correct answer: A

Rationale: Cholecystokinin (CCK) is produced in the duodenum, not the stomach, pancreas, or liver. It is released in response to the presence of food in the duodenum, where it plays a crucial role in regulating digestive processes by stimulating the release of bile from the gallbladder and enzymes from the pancreas. Therefore, the correct answer is the duodenum (Choice A). Choices B, C, and D are incorrect because CCK is not produced in the stomach, pancreas, or liver.

3. 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.

4. Which compound is necessary for emulsification of fat in the body?

• A. Bile salts
• B. Cholecystokinin
• C. Chyme
• D. Trypsin

Correct answer: A

Rationale: Bile salts are essential for emulsifying fats in the body. They break down fats into smaller droplets, increasing the surface area for enzymes to work on during digestion. Cholecystokinin is a hormone that stimulates the release of bile and pancreatic enzymes, but it is not directly involved in emulsification. Chyme is the semi-fluid mass of partly digested food that moves from the stomach to the small intestine and does not play a role in emulsifying fats. Trypsin is an enzyme produced by the pancreas that acts on proteins, not fats.

5. What is the recommended dietary intake of protein for adults?

• A. 0.5 g/kg.
• B. 0.8 g/kg.
• C. 1.0 g/kg.
• D. 1.5 g/kg.

Correct answer: B

Rationale: The recommended dietary intake of protein for adults is 0.8 grams per kilogram of body weight. This amount is considered adequate for most healthy adults. Choices A, C, and D are incorrect as they do not align with the generally recommended protein intake for adults.
