1. Low levels of high-density lipoproteins (HDL) are?

A. associated with being underweight
B. more prevalent in males
C. highly predictive of CHD risk
D. not a good predictor of CHD risk

Correct answer: C

Rationale: Low levels of HDL cholesterol are a strong predictor of coronary heart disease (CHD) risk because HDL helps to remove excess cholesterol from the bloodstream. Choice A is incorrect because low HDL levels are not associated with being underweight but rather with increased CHD risk. Choice B is incorrect as low HDL levels are not more prevalent in males but can affect both genders. Choice D is incorrect as low levels of HDL are indeed a good predictor of CHD risk.

2. What food assistance program provides a food debit card for older adults with low incomes?

A. the OAA Nutrition Program
B. Meals on Wheels
C. the Supplemental Nutrition Assistance Program
D. the Emergency Food Assistance Program

Correct answer: C

Rationale: The correct answer is C: the Supplemental Nutrition Assistance Program (SNAP). SNAP provides a food debit card to assist low-income individuals, including older adults, in purchasing food. Choice A, the OAA Nutrition Program, is incorrect as it refers to a different program specifically focused on providing nutrition services to older adults. Choice B, Meals on Wheels, is incorrect as it is a meal delivery service for homebound individuals rather than a food debit card program. Choice D, the Emergency Food Assistance Program, is incorrect as it typically involves the distribution of emergency food supplies rather than providing a food debit card.

3. Onset frequently occurs after the age of 40.

A. Type 1 Diabetes
B. Type 2 Diabetes
C.
D.

Correct answer: B

Rationale: The correct answer is B, Type 2 Diabetes. Type 2 Diabetes commonly presents with an onset after the age of 40, although it is now also seen in younger individuals due to lifestyle factors such as poor diet and lack of exercise. Type 1 Diabetes, on the other hand, typically develops in childhood or adolescence and is not associated with age over 40. Choices C and D are left blank as they are not relevant to the question.

4. Macronutrients include each of the following except one. Which one is the exception?

A. Fat
B. Polyunsaturated fatty acids
C. Carbohydrate
D. Protein

Correct answer: D

Rationale: Macronutrients are nutrients required by the body in large amounts to provide energy and include carbohydrates, fats, and proteins. While protein is essential for the body, it is not classified as a macronutrient. Proteins are made up of amino acids and serve various functions in the body, such as building and repairing tissues, but they are not a direct energy source like carbohydrates and fats. Therefore, protein is the exception among the listed options, making it the correct answer. Choice A, Fat, Choice B, Polyunsaturated fatty acids, and Choice C, Carbohydrate, are all examples of macronutrients that provide energy and support various bodily functions.

5. Dietary fiber has been recommended for its possible benefits in reducing heart disease by lowering blood cholesterol. How is fiber thought to play its role in lowering blood cholesterol?

A. Insoluble fiber binds with cholesterol in the large intestine and is excreted in feces
B. Viscous fiber binds with bile in the intestine and is excreted in feces
C. Soluble fiber binds with cholesterol in the blood and is excreted by the liver
D. Insoluble fiber converts to bile in the large intestine and binds with cholesterol

Correct answer: B

Rationale: The correct answer is B. Viscous (soluble) fiber binds with bile acids in the intestine, which are then excreted. The liver must use cholesterol to make more bile acids, thereby lowering blood cholesterol levels. Choice A is incorrect as insoluble fiber does not bind with cholesterol in the large intestine. Choice C is incorrect as soluble fiber does not directly bind with cholesterol in the blood. Choice D is incorrect as insoluble fiber does not convert to bile in the large intestine to bind with cholesterol.
