1. Which monosaccharide is the most sweet?
- A. Glucose
- B. Dextrose
- C. Fructose
- D. Sucrose
Correct answer: C
Rationale: Fructose is the sweetest of the monosaccharides. Note that glucose and dextrose are the same, and sucrose is a disaccharide, not a monosaccharide.
2. A nurse is instructing a group of clients regarding calcium-rich foods. Which of the following foods should the nurse include in the teaching as the best source of calcium?
- A. 1⁄2 cup ice cream
- B. 1 ounce Swiss cheese
- C. 1 cup milk
- D. 1 cup cottage cheese
Correct answer: 1 cup cottage cheese
Rationale: Cottage cheese is the best source of calcium among the options provided. It is rich in calcium and provides a significant amount per serving. 1 cup of cottage cheese contains more calcium compared to 1⁄2 cup of ice cream, 1 ounce of Swiss cheese, or 1 cup of milk. Ice cream is not a significant source of calcium and is often high in sugar and fat. Swiss cheese and milk contain calcium, but cottage cheese has a higher calcium content per serving, making it the best choice for meeting calcium needs.
3. Which factor has been shown to increase the risk of development of atherosclerosis?
- A. Menopause
- B. Age older than 35
- C. Increased levels of arachidonic acid
- D. Elevated HDL cholesterol
Correct answer: A: Menopause
Rationale: The correct answer is A: Menopause. Menopause is associated with an increased risk of atherosclerosis due to hormonal changes that affect lipid profiles and vascular health. Conversely, B: Age older than 35 is not necessarily a risk factor for atherosclerosis on its own, though atherosclerosis risk does generally increase with age. C: Increased levels of arachidonic acid is not specifically linked to atherosclerosis; it's a fatty acid that can be both beneficial and harmful to health depending on its metabolic pathway. D: Elevated HDL cholesterol is actually beneficial rather than harmful because HDL cholesterol is known as 'good' cholesterol that helps to reduce the risk of heart disease and atherosclerosis.
4. Being in contact with reality and the environment is a function of the:
- A. conscience
- B. ego
- C. id
- D. super ego
Correct answer: B
Rationale: Being in contact with reality and the environment is a function of the ego. The ego is responsible for mediating between the id's basic desires, the superego's idealistic standards, and the real world. The conscience (not listed as a choice) is related to feelings of guilt or moral responsibility. The id represents primal instincts, and the superego represents the internalized ideals and moral standards.
5. Which vitamin is primarily obtained from sunlight exposure?
- A. Vitamin A
- B. Vitamin C
- C. Vitamin D
- D. Vitamin E
Correct answer: C
Rationale: The correct answer is Vitamin D. Vitamin D is synthesized in the skin when it is exposed to sunlight. This process allows the body to produce Vitamin D naturally. Vitamin A (Choice A) is found in foods like liver and carrots and is not primarily obtained from sunlight. Vitamin C (Choice B) is commonly found in fruits and vegetables. Vitamin E (Choice D) is present in foods like nuts and seeds and is not primarily obtained from sunlight.
