1. Any disease that produces ____ malabsorption can bring about deficiencies of vitamins A, D, E, and K.

A. water
B. protein
C. fat
D. carbs

Correct answer: C

Rationale: Vitamins A, D, E, and K are fat-soluble, meaning they require fat for absorption. Diseases that cause fat malabsorption can lead to deficiencies in these vitamins.

2. All of the following are electrolytes except:

A. chloride
B. potassium
C. sodium
D. iron

Correct answer: D

Rationale: Iron is not an electrolyte; electrolytes like sodium, potassium, and chloride help maintain fluid balance and are critical for nerve and muscle function.

3. Which nutrient is most important for pregnant women to prevent neural tube defects?

A. Iron
B. Folate
C. Calcium
D. Vitamin D

Correct answer: B

Rationale: Folate (or folic acid) is crucial for the prevention of neural tube defects during pregnancy.

4. Starting material for sex hormones:

A. cholesterol
B. phospholipid
C. saturated
D. triglyceride

Correct answer: A

Rationale: Cholesterol is a precursor for the synthesis of sex hormones like estrogen and testosterone.

5. What is the digestive action of bile?

A. It breaks down carbohydrates
B. It breaks down proteins
C. It breaks down lipids
D. It aids in fat digestion

Correct answer: D

Rationale: Bile, which is produced by the liver and stored in the gallbladder, aids in the digestion of fats. It does this by emulsifying the fats, which makes them easier for the digestive enzymes, such as lipase, to break down. While choices A, B, and C could be seen as partially correct since fats are a type of lipid and the process of breaking down fats could be seen as breaking down lipids, the most accurate answer is D, as the primary function of bile is to aid in fat digestion, not the digestion of all types of lipids or the digestion of proteins or carbohydrates.
