ATI Nutrition Practice A

1. What is the absorbable unit of a protein?

A. Amino acid
B. Pepsin
C. Glucose
D. Sucrose

Correct answer: A

Rationale: Amino acids are the correct answer because they are the building blocks of proteins that the body absorbs after digestion. Pepsin, choice B, is incorrect as it is an enzyme that aids in the digestion of proteins, not the absorbable unit of them. Choices C and D, glucose and sucrose, are wrong because they are types of sugars, not proteins.

2. Which types of lipids must be listed on the food label? Select all that apply.

A. Total fat
B. Saturated fat
C. Trans fat
D. All of the above

Correct answer: D

Rationale: The correct answer is 'D. All of the above'. This is because, according to regulations, food labels must include the information on total fat, saturated fat, and trans fat. These types of fats are crucial for consumers to monitor, as they can significantly affect heart health. Choices A, B, and C are all correct, but they are only parts of the total information that must be provided. Therefore, the most comprehensive answer is 'D. All of the above'.

3. People with only one arm or hand may benefit from using a ____ when eating?

A. dish with suction cups
B. rocker knife
C. utensil holder
D. flexible straw

Correct answer: B

Rationale: A rocker knife is specifically designed for individuals with limited use of one hand or arm, allowing them to cut food easily. This makes it a suitable option for people with only one arm or hand. Choice A, a dish with suction cups, may not directly aid in cutting food with one hand. Choice C, an utensil holder, is not typically used for cutting food. Choice D, a flexible straw, is more related to drinking liquids and not specifically designed to assist in cutting food one-handed.

4. During early tooth development, vitamin A deficiency leads to enamel hypoplasia and defective dentin formation. Because of its effect on soft tissues and bone, vitamin A contributes to normal spacing of teeth.

A. Both statements are true.
B. Both statements are false.
C. The first statement is true; the second is false.
D. The first statement is false; the second is true.

Correct answer: A

Rationale: Both statements are true. The effect of vitamin A on the growth of soft tissues and bones naturally extends to the teeth and surrounding structures. Enamel hypoplasia, involving defective enamel matrix and incomplete calcification of enamel and dentin, can be due to vitamin A deficiency. The effect of this vitamin upon surrounding bone directly affects spacing patterns of the teeth within the bone and dentition. Choice A is correct because both statements accurately describe the influence of vitamin A on tooth development. Choices B, C, and D are incorrect as they do not reflect the accuracy of the statements provided.

5. A healthcare provider is admitting a client who practices Hinduism. The healthcare provider should identify that which of the following foods is prohibited according to Hindu dietary practices?

A. Pork
B. Chicken
C. Beef
D. Seafood

Correct answer: C

Rationale: In Hindu dietary practices, beef is prohibited due to religious beliefs. Hindus consider cows to be sacred animals, and therefore consuming beef is strictly forbidden. Pork, chicken, and seafood are not prohibited in Hindu dietary practices, making choices A, B, and D incorrect.
