1. Which nutrient group provides the primary source of energy for the body?

A. Carbohydrates.
B. Fats.
C. Proteins.
D. Vitamins.

Correct answer: A

Rationale: Carbohydrates are the body's primary source of energy. When carbohydrates are consumed, they are broken down into glucose, which is used by the body's cells for energy production. Fats and proteins are also essential nutrients, but carbohydrates are the preferred energy source for the body due to their quick conversion into fuel. Vitamins are not a direct source of energy but play crucial roles in various bodily functions.

2. The professional primarily responsible for the application of nutrition science in clinical practice settings is the:

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

Correct answer: D

Rationale: The correct answer is D: registered dietitian. A registered dietitian is a healthcare professional with specialized training in nutrition and dietetics, making them primarily responsible for applying nutrition science in clinical practice settings. Nurses (choice A) and physicians (choice B) may have some knowledge of nutrition, but a registered dietitian has specific expertise in this area. Public health nutritionists (choice C) typically focus on community nutrition and public health programs, rather than clinical practice settings.

3. Which enzyme is secreted by the salivary glands?

A. Pepsin.
B. Trypsin.
C. Sucrase.
D. Amylase.

Correct answer: D

Rationale: The correct answer is D, amylase. Amylase is an enzyme produced by the salivary glands that initiates the digestion of carbohydrates in the mouth. Pepsin (choice A) is produced in the stomach to digest proteins, trypsin (choice B) is produced in the pancreas to digest proteins, and sucrase (choice C) is produced in the small intestine to break down sucrose. Therefore, choices A, B, and C are incorrect in the context of an enzyme secreted by the salivary glands.

4. Which of the following sandwiches is high in saturated fatty acids?

A. Tuna salad
B. Grilled cheese
C. Turkey and sprouts
D. Peanut butter and jelly

Correct answer: B

Rationale: The correct answer is Grilled cheese because it is high in saturated fatty acids due to the dairy fat content in cheese. Tuna salad, turkey and sprouts, and peanut butter and jelly do not contain as high levels of saturated fatty acids as grilled cheese. Tuna salad typically contains mayonnaise which may contribute to some saturated fat content, but it is generally lower compared to the cheese in grilled cheese. Turkey and sprouts are leaner options, while peanut butter and jelly are higher in unsaturated fats rather than saturated fats.

5. To prevent symptoms of fatigue, dehydration, and energy loss, what is the daily recommended minimum intake of carbohydrates?

A. 130 g.
B. 230 g.
C. 330 g.
D. 430 g.

Correct answer: A

Rationale: The correct answer is A: 130 g. The recommended minimum intake of carbohydrates to prevent fatigue, dehydration, and energy loss is 130 grams per day. Consuming an adequate amount of carbohydrates provides the body with energy and helps prevent symptoms associated with insufficient carbohydrate intake. Choices B, C, and D are incorrect as they suggest higher amounts of carbohydrate intake, which may not necessarily align with the recommended daily minimum intake for preventing symptoms of fatigue, dehydration, and energy loss.
