1. Which set of guidelines is intended to assess nutrient adequacy or plan intakes of population groups, not individuals?

• A. Old Recommended Dietary Allowances (RDA)
• B. Estimated Average Requirement (EAR)
• C. New Recommended Dietary Allowances (RDA)
• D. Tolerable Upper Intake Level (UL)

Correct answer: B

Rationale: The Estimated Average Requirement (EAR) is specifically designed to assess nutrient adequacy or plan intakes for population groups, not for individuals. The Old and New Recommended Dietary Allowances (RDA) are meant for individuals, not groups, as they provide guidelines for specific nutrient intake levels for healthy individuals. The Tolerable Upper Intake Level (UL) is used to set the highest level of nutrient intake that is likely to pose no risk of adverse health effects for most individuals in a group, which is different from assessing nutrient adequacy for groups.

2. 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.

3. The preferred route of administration of medication in the most acute care situations is which of the following routes?

• A. Intravenous C. Subcutaneous
• B. Epidural D. Intramuscular
• C.
• D.

Correct answer: A

Rationale: Patient safety and efficacy of care depend on actions rooted in established nursing protocols that consider both the immediate and long-term needs of the patient.

4. What should be the next step in the nursing research process?

• A. Review related literature
• B. Seek permission from the hospital administrator
• C. Identify the research problem
• D. Develop methods for data collection

Correct answer: D

Rationale: The correct answer is 'Develop methods for data collection' (Choice D). In the nursing research process, after the research problem has been identified, the next step would typically be to develop methods for how data will be collected. This is essential to effectively address the research problem. 'Review related literature' (Choice A), while an important step, usually occurs after the research problem has been identified and before methods for data collection are developed. 'Seek permission from the hospital administrator' (Choice B) might be necessary at some point in certain situations, but it is not the immediate next step in the research process. 'Identify the research problem' (Choice C) would typically come before developing methods for data collection. Therefore, according to the typical sequence of steps in the nursing research process, Choice D is correct.

5. Protein-energy malnutrition (PEM) may be responsible for the increased incidence of noma and necrotizing ulcerative gingivitis (NUG) because these conditions are associated with depressed immune responses caused by nutritional deficiencies.

• A. Both the statement and the reason are correct and related
• B. Both the statement and the reason are correct but are not related
• C. The statement is correct, but the reason is not correct
• D. The statement is not correct, but the reason is correct

Correct answer: A

Rationale: The corrected question highlights that protein-energy malnutrition weakens the immune system, making individuals more susceptible to conditions like noma and NUG, which are linked to compromised immunity. Choice A is correct because the statement and reason are both accurate and directly related. Protein-energy malnutrition does result in depressed immune responses, which can predispose individuals to noma and NUG. Choice B is incorrect because the statement and reason are indeed related. Choice C is incorrect as both the statement and reason are accurate. Choice D is also incorrect as the statement is correct and directly supports the reason provided.
