1. Scurvy is caused by a deficiency of ascorbic acid (Vitamin C) because ascorbic acid is required for collagen synthesis. Is this statement true or false?

A. TRUE
B. FALSE
C. Not applicable
D. Not applicable

Correct answer: A

Rationale: The statement is accurate. Scurvy is indeed caused by a deficiency in ascorbic acid, which is another name for Vitamin C. This vitamin plays a crucial role in the synthesis of collagen, a protein that helps in the formation and strength of skin, blood vessels, tissues, and bones. When the body lacks Vitamin C, it cannot produce enough collagen, leading to symptoms associated with scurvy such as bleeding gums and weakened immunity. The choice 'False' is incorrect because it contradicts the proven medical and scientific understanding of the causes of scurvy. Choices 'C' and 'D' are marked as 'Not applicable' because the question only requires a true or false answer.

2. Can soluble fibers be fermented by gut bacteria?

A. TRUE
B. FALSE
C.
D.

Correct answer: A

Rationale: Soluble fibers can indeed be fermented by gut bacteria in the large intestine, leading to the production of beneficial short-chain fatty acids. This fermentation process is important for gut health and provides various health benefits. Therefore, the statement is true. Choice B is incorrect as it contradicts the known scientific fact that soluble fibers can be broken down by gut bacteria through fermentation.

3. During which stage of life is it most critical to build bone mass to prevent osteoporosis?

A. Infancy
B. Early childhood
C. Adolescence
D. Young adulthood

Correct answer: C

Rationale: Adolescence is the most critical stage for building bone mass, which plays a significant role in preventing osteoporosis in later life. During adolescence, approximately 45% of adult bone mass is formed. Although bone mass can be built during infancy, early childhood, and young adulthood, it is not as significant as during adolescence, making choices A, B, and D incorrect. Therefore, focusing on adequate nutrition and physical activity during adolescence is vital for long-term bone health.

4. A client who was normal weight before pregnancy asks about the recommended weight gain during pregnancy. What should the nurse advise?

A. 18-40 pounds
B. 25-35 pounds
C. 11-20 pounds
D. 15-25 pounds

Correct answer: B

Rationale: The correct answer is B: 25-35 pounds. According to standard prenatal guidelines, a client with a normal pre-pregnancy weight is recommended to gain between 25-35 pounds during pregnancy. This weight gain is important for the overall health of the mother and the developing baby. Choices A, C, and D are incorrect because they do not fall within the recommended weight gain range for a client with a normal pre-pregnancy weight.
