1. Diseases of the heart and blood vessels are collectively referred to as _____.

• A. Coronary artery disease
• B. Cardiovascular disease
• C. Coronary heart disease
• D. Coronary vessel disease

Correct answer: B

Rationale: The correct term for diseases of the heart and blood vessels is cardiovascular disease. While coronary artery disease (Choice A) specifically involves the narrowing of coronary arteries, it is just one type of cardiovascular disease. Coronary heart disease (Choice C) is also a specific condition related to the heart's blood vessels. Choice D, coronary vessel disease, is not a commonly used term to describe diseases of the heart and blood vessels. Therefore, Choice B, cardiovascular disease, is the most inclusive and appropriate term to refer to these conditions.

2. One of the most common factors that compromise the vitamin D status of older adults, particularly those living in assisted living communities is _____.

• A. decreased intake of fruits and vegetables
• B. lack of physical activity
• C. malabsorption due to atrophic gastritis
• D. lack of exposure to sunlight

Correct answer: D

Rationale: The correct answer is 'D: lack of exposure to sunlight.' Older adults, especially those in assisted living communities, are at risk of vitamin D deficiency due to spending most of their time indoors, which reduces their exposure to sunlight. Sunlight is essential for the body to produce vitamin D. Choices A, B, and C are less likely to be major factors in compromising vitamin D status. While a decreased intake of fruits and vegetables and lack of physical activity can impact overall health, they are not as directly related to vitamin D status. Malabsorption due to atrophic gastritis may affect the absorption of certain nutrients, but vitamin D synthesis primarily depends on sunlight exposure.

3. A nurse is teaching a group of adults about nutrition. The nurse should include which of the following amounts as an appropriate daily intake of fiber for adult women?

• A. 5 to 10 g
• B. 10 to 15 g
• C. 20 to 35 g
• D. 40 to 50 g

Correct answer: C

Rationale: The correct answer is 20 to 35 g. This range is the recommended daily intake of fiber for adult women. Fiber is essential for maintaining a healthy digestive system and overall well-being. Option A (5 to 10 g) is too low and may not provide sufficient fiber intake. Option B (10 to 15 g) is also below the recommended range. Option D (40 to 50 g) is too high and can lead to gastrointestinal discomfort and other complications if consumed in excess.

4. Each statement is true of proteins, except one. Which is the exception?

• A. Proteins are composed of building blocks called amino acids
• B. The classification of the 20 common amino acids is based on the properties of their side chains
• C. The general structure of an amino acid varies considerably
• D. Amino acids polymerize to form long chains called polypeptides

Correct answer: B

Rationale: The correct answer is B. The classification of the 20 common amino acids is not based on the properties of their side chains, but rather on the structure of their amino and carboxyl groups. These groups are consistent among all amino acids, while the side chains, also known as R groups, are what vary and give each amino acid its unique properties. Choice A is correct because proteins are indeed composed of amino acids. Choice C is incorrect because while the side chains of amino acids can vary, the general structure of an amino acid - a central carbon atom bonded to an amino group, a carboxyl group, a hydrogen atom, and a side chain - is consistent. Choice D is correct because amino acids do polymerize to form long chains called polypeptides, which can then fold into complex shapes to form proteins.

5. Which of the following amino acids are considered indispensable?

• A. Lysine
• B. Methionine
• C. Tryptophan
• D. Valine

Correct answer: A

Rationale: The correct answer is A: Lysine. Indispensable amino acids are those that the body cannot synthesize and must be obtained from the diet. Lysine, methionine, and tryptophan are all examples of indispensable amino acids. However, the question specifically asked for 3 out of the 9 indispensable amino acids, making 'Lysine' the correct choice. Choices B, C, and D are also indispensable amino acids but are not the focus of the question.
