1. Which change during pregnancy is related to the slowing of the gastrointestinal tract?

• A. Diarrhea
• B. Constipation
• C. Decreased absorption of iron
• D. Decreased absorption of calcium

Correct answer: B

Rationale: During pregnancy, the gastrointestinal tract tends to slow down, leading to constipation. This is due to hormonal changes that relax the intestinal muscles, allowing more time for nutrient absorption and ultimately leading to constipation. Diarrhea is not typically associated with the slowing of the gastrointestinal tract during pregnancy. Decreased absorption of iron and calcium may occur during pregnancy due to increased demands, but they are not directly related to the slowing of the gastrointestinal tract.

2. What is a major constituent of cell membranes?

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

Correct answer: B

Rationale: Phospholipids are a major component of cell membranes, providing structural integrity and facilitating cell signaling. Cholesterol (choice A) is also present in cell membranes but in smaller amounts and plays a different role. Saturated (choice C) and triglyceride (choice D) are not major constituents of cell membranes.

3. What is the digestive action of lipase?

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

Correct answer: C

Rationale: Lipase is an enzyme that specifically breaks down lipids (fats) during the process of digestion, converting them into fatty acids and glycerol. This is why option C is the correct answer. Although option D is partially correct, it's less specific than option C. Lipase does not break down carbohydrates or proteins, so options A and B are incorrect.

4. Each of the following is a form of vitamin K, except one. Which is the exception?

• A. Phylloquinone
• B. Tocopherol
• C. Menaquinone
• D. Menadione

Correct answer: B

Rationale: Tocopherol, Choice B, is not a form of vitamin K; it is another name for vitamin E. Phylloquinone (Choice A), menaquinone (Choice C), and menadione (Choice D) are all forms of vitamin K. Phylloquinone is vitamin K1 found in green plants, menaquinone is vitamin K2 produced in the large intestine and found in animal tissues, and menadione is a synthetic form of vitamin K. Therefore, Choice B is the correct answer because it does not belong to the vitamin K group, unlike the other options.

5. The term associated with loss of taste is:

• A. Xerostomia
• B. Hypogeusia
• C. Dysphagia
• D. Anosmia

Correct answer: B

Rationale: The correct answer is B, 'Hypogeusia.' Hypogeusia refers to a diminished sense of taste, which can impact nutritional intake, especially in older adults. Xerostomia (choice A) is dry mouth, Dysphagia (choice C) is difficulty swallowing, and Anosmia (choice D) is the loss of the sense of smell. These conditions are different from loss of taste, making them incorrect choices for this question.
