1. Which two dietary components may help decrease blood cholesterol levels?

• A. Omega-3 fatty acids and soluble fiber
• B. Short-chain fatty acids and insoluble fiber
• C. Trans fatty acids and potassium
• D. Cis fatty acids and calcium

Correct answer: A

Rationale: The correct answer is A: Omega-3 fatty acids and soluble fiber. Omega-3 fatty acids are known to reduce triglycerides, while soluble fiber helps to lower LDL cholesterol levels. Both of these components are beneficial in managing blood cholesterol levels. Choice B, short-chain fatty acids and insoluble fiber, is incorrect as they do not have the same cholesterol-lowering effects as omega-3 fatty acids and soluble fiber. Choice C, trans fatty acids and potassium, is incorrect as trans fatty acids can raise LDL cholesterol levels and increase the risk of heart disease. Choice D, cis fatty acids and calcium, is incorrect as cis fatty acids are common in natural fats and do not specifically help in reducing blood cholesterol levels.

2. Which of the following converts starch to disaccharides, and this reaction occurs in the _____?

• A. pancreatic amylases, small intestine
• B. brush border enzymes, small intestine
• C. luminal enzymes, large intestine
• D. pancreatic amylases, pancreas

Correct answer: A

Rationale: The correct answer is A. Pancreatic amylases break down starch into disaccharides in the small intestine. This process occurs in the small intestine, not the large intestine or pancreas. Brush border enzymes act on disaccharides to break them down into monosaccharides, while luminal enzymes are not specifically involved in the conversion of starch to disaccharides.

3. Which nutrient is most important for the prevention of osteoporosis?

• A. Vitamin A
• B. Iron
• C. Calcium
• D. Protein

Correct answer: C

Rationale: Calcium is the most important nutrient for bone health and the prevention of osteoporosis. Calcium plays a crucial role in maintaining bone density and strength. Vitamin A is important for vision and immune function but is not directly related to bone health. Iron is essential for oxygen transport in the blood, while protein is important for muscle growth and repair. However, in the context of preventing osteoporosis, calcium is the key nutrient.

4. Worldwide, what is the most common nutrient deficiency?

• A. magnesium deficiency
• B. iron deficiency
• C. selenium deficiency
• D. zinc deficiency

Correct answer: B

Rationale: Iron deficiency is the most common nutrient deficiency globally. It leads to anemia and affects many populations, especially women and children. Magnesium, selenium, and zinc deficiencies are important, but they are not as prevalent as iron deficiency on a global scale.

5. Which of the following interventions should be considered the highest priority when caring for June, who has hemiparesis secondary to a stroke?

• A. Position June in an upright lateral position
• B. Perform range of motion exercises
• C. Apply antiembolic stockings
• D. Use hand rolls or pillows for support

Correct answer: C

Rationale: The correct answer is C, 'Apply antiembolic stockings'. In the case of a patient who has experienced a stroke and is suffering from hemiparesis, the highest priority intervention is to prevent further complications such as deep vein thrombosis (DVT), which can be life-threatening. Antiembolic stockings are used to increase venous blood flow velocity and reduce the risk of DVT. Choice 'A', positioning June in an upright lateral position, while important for overall care, is not the highest priority. Choice 'B', performing range of motion exercises, is an important part of recovery but not the immediate priority. Choice 'D', using hand rolls or pillows for support, is also a valuable intervention but does not address the most pressing risk of further complications.
