1. Which vitamin is also known as Niacin?

• A. Vitamin B1
• B. Vitamin B2
• C. Vitamin B3
• D. Vitamin B12

Correct answer: C

Rationale: The correct answer is Vitamin B3, also known as Niacin. Niacin is essential for energy metabolism and can help improve cholesterol levels. Vitamin B1 is Thiamine, Vitamin B2 is Riboflavin, and Vitamin B12 is Cobalamin. These vitamins have different functions in the body and are not synonymous with Niacin.

2. When should a newborn transition to whole milk according to dietary teaching for breastfeeding parents?

• A. 6 months
• B. 8 months
• C. 10 months
• D. 12 months

Correct answer: D

Rationale: Breast milk or formula should be the primary source of nutrition for infants up to around 1 year of age. The transition to whole cow's milk is recommended at 12 months of age, not earlier. Introducing whole milk before 12 months can lead to digestive issues and nutrient deficiencies. Therefore, choices A, B, and C are incorrect as they suggest transitioning to whole milk before the recommended age of 12 months.

3. An elderly man is hospitalized with a diagnosis of malnutrition three months following his wife's death. What risk factor for malnutrition does this scenario illustrate?

• A. A history of chronic illness
• B. Depression or social isolation
• C. Age
• D. Impaired mobility

Correct answer: B

Rationale: This scenario illustrates depression or social isolation as a risk factor for malnutrition. After the death of his wife, the elderly man may have experienced depression or social isolation, which can lead to decreased food intake and poor nutritional status. Although age, chronic illness, and impaired mobility can also contribute to malnutrition, they are not the primary factors described in this scenario. The history of chronic illness (Choice A) and impaired mobility (Choice D) were not mentioned in the scenario, and while age (Choice C) is a factor, it's not the main factor depicted in this case.

4. What physiologic role does calcium 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: A

Rationale: The correct answer is A: 'Blood clotting, transmission of nerve impulses, muscle contraction and relaxation.' Calcium plays a crucial role in various physiological functions such as blood clotting, transmission of nerve impulses, muscle contraction and relaxation, membrane permeability, and activation of certain enzymes. Choice B is incorrect because while calcium is involved in calcium homeostasis, it is not the only role it plays in the body. Choice C is incorrect as calcium indeed has several known metabolic functions, and it is not solely for preventing caries. Choice D is also incorrect as the functions mentioned are primarily carried out by other nutrients and not specifically by calcium.

5. A nurse is providing nutritional education to a client who is obese. The nurse should include in the information that which of the following gastrointestinal disorders is commonly associated with obesity?

• A. Peptic ulcer disease
• B. Gastroesophageal reflux disease
• C. Celiac disease
• D. Crohn’s disease

Correct answer: B

Rationale: Gastroesophageal reflux disease (GERD) is commonly associated with obesity due to increased abdominal pressure and other factors. Peptic ulcer disease (Choice A) is not commonly associated with obesity. Celiac disease (Choice C) is an autoimmune disorder triggered by gluten consumption and is not directly linked to obesity. Crohn’s disease (Choice D) is a type of inflammatory bowel disease and is not specifically associated with obesity.
