1. Where is Vitamin E commonly found?

A. produced by bacteria in the GI tract
B. synthesized by the body through sunlight exposure
C. associated with beriberi deficiency
D. present in vegetable oils

Correct answer: D

Rationale: Vitamin E is an antioxidant commonly found in sources like vegetable oils, nuts, seeds, and green leafy vegetables. It plays a crucial role in protecting cells from damage. Choices A and B are incorrect as Vitamin E is not produced by bacteria in the GI tract nor synthesized by sunlight exposure. Choice C is incorrect as beriberi is a deficiency of Vitamin B1 (thiamine), not Vitamin E.

2. A healthcare provider is on a med-surg unit caring for a client who follows the dietary laws of Orthodox Judaism. Which of the following menu selections should the healthcare provider recommend for this client?

A. Fried catfish
B. Broiled shrimp
C. Pork sausage
D. Grilled vegetables

Correct answer: D

Rationale: The correct answer is D: Grilled vegetables. Orthodox Judaism restricts the consumption of certain animals, including catfish, shrimp, and pork, making choices A, B, and C inappropriate for a client following these dietary laws. Grilled vegetables are a safe and suitable option that complies with Orthodox Jewish dietary guidelines.

3. Bacterial growth and plaque formation are enhanced by a diet with frequent intake of retentive carbohydrates. Gingivitis is an irreversible change in the interdental papillary tissues.

A. Both statements are true
B. Both statements are false
C. The first statement is true; the second is false
D. The first statement is false; the second is true

Correct answer: C

Rationale: The correct answer is C. The first statement is true; retentive carbohydrates promote bacterial growth and plaque formation. However, the second statement is false; gingivitis is not irreversible and is often reversible with proper care. Gingivitis is the inflammation of the gums due to plaque buildup and poor oral hygiene. With good oral hygiene practices and professional dental care, gingivitis can be reversed. The other choices are incorrect because gingivitis is not irreversible, making statement two false.

4. In approximately what percentage of cases is the prevalence seen?

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

Correct answer: A

Rationale: The correct answer is A, Type 1 Diabetes. The prevalence of Type 1 Diabetes is seen in approximately 5% to 10% of cases. This statement highlights a key epidemiological characteristic of Type 1 Diabetes. Choice B, Type 2 Diabetes, is incorrect because the prevalence mentioned does not align with Type 2 Diabetes, which has a much higher prevalence in the general population. Choices C and D are not relevant to the question and can be disregarded.

5. Which enzyme digests fiber in the large intestine?

A. salivary amylase
B. pancreatic amylase
C. cellulase
D. none of the above

Correct answer: D

Rationale: The correct answer is 'none of the above.' Human digestive enzymes like salivary amylase and pancreatic amylase cannot digest fiber. Instead, fiber is fermented by gut bacteria in the large intestine. Cellulase, which is an enzyme produced by some animals and microorganisms, can break down cellulose found in plants, but it is not a human digestive enzyme, making it an incorrect choice in this context.
