Which enzyme initiates protein digestion in the stomach?
- A. Pepsin
- B. Salivary Amylase
- C. CCK
- D. Secretin
Correct Answer: A
Rationale: Pepsin is the enzyme that initiates protein digestion in the stomach. It breaks down proteins into smaller peptides, aiding in their further digestion and absorption in the intestines. Salivary Amylase (Choice B) functions in breaking down dietary carbohydrates in the mouth, not proteins. CCK (Choice C) and Secretin (Choice D) are hormones involved in the digestion of fats and carbohydrates, not proteins. Therefore, Choices B, C, and D are incorrect in the context of protein digestion in the stomach.

Which dietary recommendation is most appropriate for a patient with gout?
- A. Increase protein intake
- B. Reduce carbohydrate intake
- C. Avoid purine-rich foods
- D. Increase calcium intake
Correct Answer: C
Rationale: The most appropriate dietary recommendation for a patient with gout is to avoid purine-rich foods. Purine-rich foods such as red meat and shellfish can lead to increased uric acid levels in the body, triggering gout flare-ups. Increasing protein intake (Choice A) is not recommended as some high-protein foods are also high in purines. Reducing carbohydrate intake (Choice B) and increasing calcium intake (Choice D) are not directly related to managing gout symptoms.
According to the DASH Eating Plan, Carmen's daily sodium intake should not exceed how many milligrams to ensure the plan's effectiveness?
- A. 1000 milligrams
- B. 2500 milligrams
- C. 3000 milligrams
- D. 1500 milligrams
Correct Answer: D
Rationale: The DASH Eating Plan is designed to lower blood pressure and is most effective when daily sodium intake is limited to 1500 milligrams or less. Therefore, choice D is the correct answer. Choices A (1000 milligrams), B (2500 milligrams), and C (3000 milligrams) are incorrect because they either fall below or exceed the recommended daily sodium intake for the DASH Eating Plan.
Can a person with Celiac disease eat Poptarts that contain gluten?
- A. Yes
- B. No
- C. Only in small quantities
- D. Only if they are gluten-free Poptarts
Correct Answer: B
Rationale: A person with Celiac disease cannot consume Poptarts that contain gluten because gluten is a protein found in wheat, barley, and rye, triggering an autoimmune response in individuals with Celiac disease and damaging their small intestine. Even small quantities of gluten can lead to this harmful response, making choices 'A' and 'C' incorrect. While gluten-free Poptarts may be suitable for individuals with Celiac disease, regular Poptarts containing gluten are not safe for consumption by them, rendering choice 'D' incorrect as well.
With which type of cancer is asbestos exposure most strongly associated?
- A. Liver cancer
- B. Peritoneal cancer
- C. Skin cancer
- D. Esophageal cancer
Correct Answer: B
Rationale: Asbestos exposure is most strongly associated with peritoneal cancer, a type of cancer that affects the lining of the abdomen. While asbestos can potentially contribute to other types of cancer, there is a significant body of research indicating a robust correlation between asbestos exposure and peritoneal cancer. Asbestos exposure can also lead to mesothelioma, a cancer that affects the lining of the chest. The other options - liver cancer, skin cancer, and esophageal cancer - are not typically associated with asbestos exposure.
Men generally have a higher RDA than women, except during pregnancy and lactation when women's nutritional needs increase significantly.
- A. TRUE
- B. FALSE
Correct Answer: A
Rationale: The statement is TRUE. Men typically require a higher Recommended Dietary Allowance (RDA) than women due to physiological differences. However, during pregnancy and lactation, women's nutritional needs increase significantly to support the growth and development of the baby. Therefore, during these stages, women may require a higher RDA compared to men. This exception is crucial to consider when evaluating nutritional requirements based on gender.
