1. Which observation provides evidence that a person has good nutritional status?

• A. Small muscle mass.
• B. Normal weight-to-height ratio.
• C. Smooth tongue.
• D. Fragile skin.

Correct answer: B

Rationale: A normal weight-to-height ratio is a reliable indicator of good nutritional status as it suggests that the person is well-nourished and not underweight or overweight. Small muscle mass (choice A) can indicate malnutrition, a smooth tongue (choice C) can be a sign of vitamin deficiencies, and fragile skin (choice D) can be a sign of poor nutrition or other health issues, but they are not as direct indicators of good nutritional status as a normal weight-to-height ratio.

2. Where are the parotid, submandibular, and sublingual glands found?

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

Correct answer: A

Rationale: The parotid, submandibular, and sublingual glands are the main salivary glands located in the mouth. They play a crucial role in producing saliva, which aids in digestion. The stomach (choice B) is where gastric juices are produced, the pancreas (choice C) secretes digestive enzymes into the small intestine, and the duodenum (choice D) is the first part of the small intestine where most chemical digestion occurs. Therefore, the correct answer is the mouth (choice A) as it is where these salivary glands are situated.

3. Which hormone is responsible for stimulating the gallbladder to contract and release bile?

• A. gastric lipase
• B. cholecystokinin
• C. vitamin D
• D. enterokinin

Correct answer: B

Rationale: Cholecystokinin (CCK) is the correct answer. It is the hormone responsible for stimulating the gallbladder to contract and release bile to aid in fat digestion. Gastric lipase (Choice A) is an enzyme that breaks down fats in the stomach, not a hormone involved in gallbladder function. Vitamin D (Choice C) is important for calcium absorption and bone health, but it is not directly related to gallbladder function. Enterokinin (Choice D) is a peptide hormone that affects smooth muscle contractions in the gastrointestinal tract, but it is not specifically responsible for stimulating the gallbladder to release bile.

4. The sum of all chemical processes inside living cells of the body that sustain life and health is known as:

• A. physiology
• B. digestion
• C. metabolism
• D. nutrition

Correct answer: C

Rationale: Metabolism is the correct answer as it refers to the sum of all chemical processes that occur within living cells to maintain life and health. Physiology (Choice A) is the study of how living organisms function but does not specifically refer to cellular chemical processes. Digestion (Choice B) is the process of breaking down food in the body, not the overall cellular processes. Nutrition (Choice D) is the process of obtaining and consuming food necessary for health and growth, but it does not encompass all cellular processes related to sustaining life and health.

5. Which of the following is an example of a disaccharide?

• A. Glucose.
• B. Fructose.
• C. Galactose.
• D. Maltose.

Correct answer: D

Rationale: The correct answer is D, Maltose. A disaccharide is formed when two monosaccharides are joined together. Glucose, fructose, and galactose are all monosaccharides, not disaccharides. Therefore, they are not examples of disaccharides.
