What is the most common nutritional disorder for the older adult?
- A. Obesity
- B. Underweight
- C. Vitamin deficiency
- D. Dehydration
Correct Answer: A
Rationale: The correct answer is A: Obesity. Among older adults, obesity is the most common nutritional disorder. This is often attributed to reduced physical activity levels and changes in metabolism that occur with aging. Choice B (Underweight) is less common among older adults as compared to obesity. While choices C (Vitamin deficiency) and D (Dehydration) are important nutritional issues, they are generally not as prevalent as obesity in the older adult population.

A condition that often progresses to become type 2 diabetes mellitus is:
- A. type 1 diabetes mellitus
- B. high blood pressure
- C. chronic pancreatitis
- D. impaired glucose tolerance
Correct Answer: D
Rationale: Impaired glucose tolerance is a pre-diabetic state characterized by higher than normal blood sugar levels. It is often associated with insulin resistance and can progress to type 2 diabetes mellitus. Type 1 diabetes mellitus (Choice A) is an autoimmune condition where the body attacks insulin-producing cells, leading to a lack of insulin production. High blood pressure (Choice B) and chronic pancreatitis (Choice C) are not directly linked to the progression to type 2 diabetes mellitus.
Which nutrients might people who follow a vegan diet be deficient in?
- A. Vitamin B12
- B. Vitamin C
- C. Vitamins A and D
- D. Calcium
Correct Answer: C
Rationale: People who adhere to a vegan diet might indeed be deficient in vitamins A and D, which are primarily found in animal-derived foods. While vitamin B12 and calcium can also be lacking in a vegan diet, these were not choices given that would correctly answer the question. Vitamin C, on the other hand, is widely available in numerous plant-based foods, making it less likely for vegans to be deficient in it. Therefore, the correct answer is 'Vitamins A and D'. It's important to note that deficiencies can be avoided through careful meal planning or supplementation.
Which enzyme initiates protein digestion in the stomach?
- A. Pepsin
- B. Salivary Amylase
- C. CCK
- D. Secretin
Correct Answer: A
Rationale: Pepsin is the enzyme that initiates protein digestion in the stomach. It breaks down proteins into smaller peptides, aiding in their further digestion and absorption in the intestines. Salivary Amylase (Choice B) functions in breaking down dietary carbohydrates in the mouth, not proteins. CCK (Choice C) and Secretin (Choice D) are hormones involved in the digestion of fats and carbohydrates, not proteins. Therefore, Choices B, C, and D are incorrect in the context of protein digestion in the stomach.
Which biomolecule is responsible for the storage and transfer of genetic information?
- A. Carbohydrates
- B. Proteins
- C. Lipids
- D. Nucleic acids
Correct Answer: D
Rationale: Nucleic acids, such as DNA and RNA, are the biomolecules responsible for storing and transferring genetic information within cells. Carbohydrates, proteins, and lipids do not have this specific function. Carbohydrates are mainly used for energy storage, structural support, and cellular communication. Proteins are involved in various cellular functions such as enzymatic reactions, structural support, and signaling. Lipids play roles in energy storage, cell membrane structure, and signaling.
