1. Each of the following is a fat-soluble vitamin except for one. Which is the exception?

• A. Vitamin A
• B. Vitamin C
• C. Vitamin D
• D. Vitamin K

Correct answer: B

Rationale: The correct answer is B, Vitamin C. Vitamin C is a water-soluble vitamin, not fat-soluble. Fat-soluble vitamins are Vitamins A, D, E, and K. These vitamins are stored in the body's fat tissues and liver, unlike water-soluble vitamins which are not stored and are eliminated in urine, making them less likely to reach toxic levels.

2. Being in contact with reality and the environment is a function of the:

• A. conscience
• B. ego
• C. id
• D. super ego

Correct answer: B

Rationale: Being in contact with reality and the environment is a function of the ego. The ego is responsible for mediating between the id's basic desires, the superego's idealistic standards, and the real world. The conscience (not listed as a choice) is related to feelings of guilt or moral responsibility. The id represents primal instincts, and the superego represents the internalized ideals and moral standards.

3. Where is Vitamin K synthesized?

• A. by bacteria in the GI tract
• B. by the body by sunlight
• C. deficiency is called beriberi
• D. found in vegetable oils

Correct answer: A

Rationale: Vitamin K is synthesized by bacteria in the gastrointestinal tract. Choice B is incorrect as the synthesis of Vitamin D, not K, can be induced by sunlight exposure. Choice C is incorrect as beriberi is a condition caused by thiamine (Vitamin B1) deficiency, not Vitamin K. Choice D is incorrect as Vitamin E is commonly found in vegetable oils, not Vitamin K.

4. 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.

5. Which type of diabetes is often associated with a BMI greater than 25 and an increased percentage of body fat, particularly in the abdominal region, contributing to insulin resistance?

• A. Type 1 Diabetes
• B. Type 2 Diabetes
• C. Gestational Diabetes
• D. Prediabetes

Correct answer: B

Rationale: The correct answer is B. Type 2 Diabetes is often associated with a BMI greater than 25 and an increased percentage of body fat, particularly in the abdominal region, contributing to insulin resistance. Type 1 Diabetes is an autoimmune condition not primarily linked to BMI or body fat percentage. Gestational Diabetes occurs during pregnancy and is not directly related to BMI. Prediabetes is a condition where blood sugar levels are higher than normal but not high enough to be diagnosed as Type 2 Diabetes; although it can be associated with higher BMI, it is not as definitive as in Type 2 Diabetes.
