1. Which nutrient is most closely associated with the prevention of neural tube defects in a developing fetus for a woman planning to become pregnant?

• A. Calcium
• B. Folate
• C. Vitamin A
• D. Choline

Correct answer: B

Rationale: The correct answer is folate. Folate, also known as Vitamin B9, is vital for the prevention of neural tube defects in the developing fetus. It is primarily responsible for the creation and repair of DNA, which is essential during rapid growth stages such as pregnancy. While nutrients like calcium, vitamin A, and choline are important for pregnancy, they are not as directly linked to preventing neural tube defects as folate. Calcium is crucial for the baby's bone and teeth development. Vitamin A is essential for vision, immune function, and cellular growth. Choline supports brain development and neural functioning. However, none of these nutrients have the same direct impact on preventing neural tube defects as folate.

2. A nurse is teaching a group of clients about stress. Which of the following should the nurse include in the teaching?

• A. Protein requirements decrease in times of stress.
• B. Acute stress causes an increase in metabolism.
• C. Stress causes a positive nitrogen balance in the body.
• D. Glucose is broken down more slowly during times of stress.

Correct answer: B

Rationale: The correct answer is B: Acute stress causes an increase in metabolism. During acute stress, the body's fight-or-flight response is activated, leading to an increase in metabolism to provide energy for the body to respond to the stressor. Choices A, C, and D are incorrect. Protein requirements actually increase during times of stress to support the body's needs. Stress typically leads to a negative nitrogen balance in the body, not a positive one. Glucose is broken down more rapidly, not slowly, during times of stress to provide immediate energy.

3. Saturated fats are generally found in animal products with a few exceptions. Which of the following is a plant product that contains a large proportion of saturated fat?

• A. canola oil
• B. olive oil
• C. soybean oil
• D. coconut oil

Correct answer: D

Rationale: Coconut oil is a plant-based oil that is high in saturated fat, unlike most other plant oils, which are typically unsaturated.

4. What is the role of fat in digestion?

• A. Digest fats in the stomach
• B. Emulsify fats in the small intestine
• C. Transport fats through the circulatory system
• D. Split fats into smaller components

Correct answer: B

Rationale: The correct answer is B: Emulsify fats in the small intestine. Bile emulsifies fats in the small intestine, breaking them down into smaller droplets that can be more easily digested by enzymes like lipase. Choice A is incorrect as fats are not digested in the stomach but rather in the small intestine. Choice C is incorrect as fats are transported through the lymphatic system instead of the circulatory system. Choice D is incorrect as fats are broken down into smaller components through emulsification, not splitting.

5. What dietary strategy would most likely be used as part of lifestyle management to reduce the risk of coronary heart disease?

• A. Avoid foods that contain polyunsaturated fat
• B. Limit saturated fat to less than 10 percent of total calories
• C. Limit alcohol intake to one drink daily for women and two drinks daily for men
• D. Avoid consumption of fish and shellfish

Correct answer: C

Rationale: Limiting alcohol intake is part of a strategy to reduce the risk of coronary heart disease by avoiding the negative cardiovascular effects associated with excessive alcohol consumption.
