1. Which food provides a 1-ounce serving of grains for a preschool child?

A. 1 cup of ready-to-eat cereal flakes
B. 1â„2 slice of whole wheat bread
C. 1â„2 of a 6-inch flour tortilla
D. 1 cup of cooked rice

Correct answer: A

Rationale: The correct answer is A: 1 cup of ready-to-eat cereal flakes. For a preschool child, 1 cup of ready-to-eat cereal flakes provides a 1-ounce serving of grains, meeting the requirement. Choice B, 1â„2 slice of whole wheat bread, is not the correct answer as it does not constitute a 1-ounce serving of grains. Similarly, choice C, 1â„2 of a 6-inch flour tortilla, does not offer a 1-ounce serving of grains. Choice D, 1 cup of cooked rice, also does not provide a 1-ounce serving of grains for a preschool child, making it an incorrect choice.

2. Bones continuously lose and gain minerals. This ongoing process is called?

A. reorganization
B. reorienting
C. demineralizing
D. remodeling

Correct answer: D

Rationale: The correct answer is D, 'remodeling.' Remodeling is the process by which bones continuously lose and gain minerals, maintaining bone strength and integrity over time. 'Reorganization' (choice A), 'reorienting' (choice B), and 'demineralizing' (choice C) do not accurately describe the process of bones continuously losing and gaining minerals.

3. A client with Crohn's disease is receiving parenteral nutrition. Which of the following interventions should the nurse not include in the care of this client?

A. Remove the parenteral nutrition solution from the refrigerator 2 hours before infusion.
B. Remove unused parenteral nutrition after 12 hours of use.
C. Monitor daily laboratory values and report abnormalities as needed.
D. Monitor the flow rate of the parenteral nutrition carefully and adjust it if necessary.

Correct answer: B

Rationale: In caring for a client receiving parenteral nutrition, it is important to follow proper guidelines to ensure safety and effectiveness. Unused parenteral nutrition should be removed after 24 hours, not 12 hours, to prevent contamination and reduce the risk of infection. Option A is correct as it ensures the solution is at room temperature before infusion. Option C is essential for monitoring the client's response to parenteral nutrition. Option D is important to maintain the correct flow rate and adjust it as needed. Therefore, option B is the incorrect choice among the options provided.

4. What describes a common physical change of aging that can affect an older adult's nutrition?

A. reduced salivary output
B. increased gastrointestinal motility
C. abnormal cortisol production
D. increase in number of taste buds

Correct answer: A

Rationale: Reduced salivary output is a common physical change in aging. This can affect an older adult's nutrition by impacting chewing, swallowing, and taste perception. The decrease in saliva production can make it harder to chew and swallow food effectively, affecting the overall eating experience. Additionally, saliva plays a role in taste perception, so a reduction in salivary output can lead to alterations in how food tastes, potentially impacting an individual's appetite and food choices. Increased gastrointestinal motility (choice B) is not typically associated with aging and would not directly affect nutrition. Abnormal cortisol production (choice C) is related to hormonal changes and is not a common physical change of aging that affects nutrition. An increase in the number of taste buds (choice D) is not a typical change associated with aging and would not have a significant impact on an older adult's nutrition.

5. Each statement is true of proteins, except one. Which is the exception?

A. Proteins are composed of building blocks called amino acids
B. The classification of the 20 common amino acids is based on the properties of their side chains
C. The general structure of an amino acid varies considerably
D. Amino acids polymerize to form long chains called polypeptides

Correct answer: B

Rationale: The correct answer is B. The classification of the 20 common amino acids is not based on the properties of their side chains, but rather on the structure of their amino and carboxyl groups. These groups are consistent among all amino acids, while the side chains, also known as R groups, are what vary and give each amino acid its unique properties. Choice A is correct because proteins are indeed composed of amino acids. Choice C is incorrect because while the side chains of amino acids can vary, the general structure of an amino acid - a central carbon atom bonded to an amino group, a carboxyl group, a hydrogen atom, and a side chain - is consistent. Choice D is correct because amino acids do polymerize to form long chains called polypeptides, which can then fold into complex shapes to form proteins.
