1. Low levels of physical activity are more commonly associated with which type of cancer?

• A. Esophageal cancer
• B. Pancreatic cancer
• C. Lung cancer
• D. Colon cancer

Correct answer: D

Rationale: Low physical activity is most strongly associated with an increased risk of colon cancer. Regular exercise helps regulate bowel movements and reduce inflammation, which are factors that can contribute to the development of colon cancer. Esophageal cancer, pancreatic cancer, and lung cancer are not as directly linked to low levels of physical activity.

2. Why is atherosclerosis dangerous to arterial function?

• A. It diminishes central circulation
• B. It causes decreased blood pressure on artery walls
• C. It narrows the arterial lumen so a clot can easily block it
• D. It increases arterial elasticity

Correct answer: C

Rationale: Atherosclerosis is dangerous to arterial function because it narrows the arterial lumen, increasing the risk of a clot completely blocking the blood flow. This can lead to severe cardiovascular events such as heart attacks or strokes. Choice A is incorrect since atherosclerosis does not primarily diminish central circulation, but rather, it impedes local blood flow where the plaque is present. Choice B is also incorrect as atherosclerosis increases the pressure on artery walls due to the narrowed space for blood flow, not decrease it. Lastly, choice D is incorrect as atherosclerosis causes the arteries to lose their elasticity, not increase it.

3. Which is the best description of a full-liquid diet?

• A. Most suitable for individuals with an ileostomy
• B. Suitable for individuals with lactose intolerance
• C. Contains low saturated fat and high fiber
• D. Provides adequate nutrients and is easily digested

Correct answer: D

Rationale: The correct answer is D because a full-liquid diet is designed to provide adequate nutrients while being easily digested. Choices A and B are incorrect because a full-liquid diet is not specifically tailored for individuals with an ileostomy or lactose intolerance. Choice C is also incorrect as it describes characteristics that are not defining features of a full-liquid diet.

4. Sugar alcohols have anticariogenic properties and can protect the teeth by decreasing demineralization, enhancing remineralization, or increasing salivary flow, even in the presence of a fermentable carbohydrate. Name 3 sugar alcohols.

• A. Sorbitol
• B. Mannitol
• C. Xylitol
• D. Erythritol

Correct answer: D

Rationale: Sugar alcohols such as sorbitol, mannitol, and xylitol are commonly used in sugar-free products and have properties that help protect teeth from caries by promoting remineralization and increasing salivary flow. Erythritol is another common sugar alcohol used as a sweetener in various products, but it was not listed in the question.

5. Each of the following describes the physiologic roles of water, except one. Which is the exception?

• A. Acts as a solvent for chemical reactions.
• B. Maintains stability of body fluids.
• C. Enables transport of nutrients and excretion of waste.
• D. Regulates temperature by pooling as perspiration on skin.

Correct answer: D

Rationale: The correct answer is D. Water regulates body temperature by evaporating as perspiration from the skin, not by pooling. When sweat evaporates from the skin, it takes away heat, which helps cool the body. Choices A, B, and C are correct because water acts as a solvent for chemical reactions, maintains the stability of body fluids, and enables the transport of nutrients and excretion of waste, respectively.
