1. Which type of assessment evaluates a person's risk of malnutrition by ranking key variables from the medical history and physical examination?

• A. Katz index
• B. integrated assessment
• C. subjective global assessment
• D. nutrition care plan

Correct answer: C

Rationale: The Subjective Global Assessment (SGA) is the correct choice. SGA is a comprehensive tool used to assess an individual's risk of malnutrition by integrating key variables from the medical history, physical examination, and other relevant factors. The Katz index is used to assess activities of daily living, not malnutrition risk. An integrated assessment refers to the overall evaluation process involving multiple assessments. A nutrition care plan is a personalized plan developed based on assessment findings, not the assessment itself.

2. What is the primary goal of a dental hygienist when making dietary recommendations for a patient with a new dental prosthesis?

• A. To promote healing and repair by ensuring an adequate and nutrient-dense diet
• B. To promote healing and repair by recommending consumption of only liquids for the first week
• C. To promote a balanced diet by recommending a variety of fibrous foods
• D. To encourage the patient to become accustomed to the prosthesis by eating as usual

Correct answer: A

Rationale: The primary goal of a dental hygienist when making dietary recommendations for a patient with a new dental prosthesis is to promote healing and repair. This can be achieved by ensuring the patient maintains an adequate and nutrient-dense diet. This is why option 'A' is the correct answer. Option 'B' is incorrect because while liquids are easier to consume with a new dental prosthesis, a diet consisting only of liquids for a week may not provide all necessary nutrients. Option 'C' is incorrect because while a variety of fibrous foods can contribute to a healthy diet, it's not specifically relevant to the healing and adjustment to a new dental prosthesis. Option 'D' is incorrect because eating as usual may not be feasible or comfortable for a patient with a new prosthesis, and it doesn't specifically focus on promoting healing and repair.

3. What physiologic role does magnesium play in the body?

• A. Blood clotting, transmission of nerve impulses, muscle contraction and relaxation
• B. Calcium homeostasis, structural integrity of heart muscle
• C. No known metabolic function, caries-preventing properties
• D. ATP energy release; metabolism of fats, carbohydrates, proteins; regulates acid-base balance

Correct answer: B

Rationale: The correct answer is B. Magnesium plays an important role in maintaining calcium homeostasis and preventing skeletal abnormalities. It is involved in more than 300 enzymatic reactions, including energy metabolism, insulin activity, and glucose use. Magnesium is vital to the structural integrity of heart muscle and other muscles and nerves. While magnesium does play a role in blood clotting, nerve impulses, muscle contraction, relaxation, ATP energy release, and metabolism of fats, carbohydrates, proteins, the primary physiologic role of magnesium in the body is related to calcium homeostasis and maintaining the structural integrity of the heart muscle. Choice A is incorrect because it includes functions of magnesium, but they are not its primary physiologic role. Choice C is incorrect as magnesium has several known metabolic functions. Choice D is incorrect because although magnesium is involved in ATP energy release and metabolism, its primary role is related to calcium homeostasis and structural integrity of muscle.

4. Which of the following is NOT required on a food label or nutrition facts panel?

• A. Nutrition facts panel
• B. Ingredients in descending order by weight
• C. The % RDA of ALL the vitamins and minerals in the product
• D. Essential warnings, such as common allergies

Correct answer: C

Rationale: According to food labeling regulations, every food label or nutrition facts panel must include a nutrition facts panel, list of ingredients in descending order by weight, and essential warnings such as common allergies. However, it is not mandatory to list the % Recommended Daily Allowance (RDA) of ALL the vitamins and minerals in the product. Only certain vitamins and minerals, deemed significant to public health, are required to be listed. Therefore, the notion that the % RDA of ALL vitamins and minerals must be displayed is incorrect. Choices A, B, and D are required elements on a food label, making them incorrect answers.

5. _____ neutralizes stomach acid in the small intestine:

• A. saliva
• B. gastric mucus
• C. bicarbonate ions
• D. enzymes

Correct answer: C

Rationale: The correct answer is C: bicarbonate ions. Bicarbonate ions, secreted by the pancreas, neutralize the acidic chyme entering the small intestine from the stomach, creating a more suitable environment for digestive enzymes. Saliva (choice A) helps in the initial breakdown of food in the mouth, not in neutralizing stomach acid. Gastric mucus (choice B) protects the stomach lining from the acidic environment but does not neutralize the acid in the small intestine. Enzymes (choice D) facilitate chemical reactions in digestion but do not neutralize stomach acid.
