1. What is the function of villi and microvilli in the GI tract?
- A. produce bile
- B. kill bacteria
- C. produce vitamin K
- D. increase the surface area for absorption
Correct answer: D
Rationale: Villi and microvilli in the GI tract serve to increase the surface area of the small intestine, aiding in the absorption of nutrients into the bloodstream. Choices A, B, and C are incorrect as villi and microvilli are primarily involved in enhancing absorption, not in producing bile, killing bacteria, or producing vitamin K.
2. Which type of nutritional deficiency results from inadequate absorption?
- A. Unmeasurable
- B. Primary deficiency
- C. Secondary deficiency
- D. Codependent
Correct answer: C
Rationale: The correct answer is C: Secondary deficiency. A nutritional deficiency resulting from decreased intake is called a primary deficiency. On the other hand, a secondary deficiency refers to a vitamin deficiency caused by inadequate absorption or use, increased requirements, excretion, or destruction. Choice A, 'Unmeasurable,' is incorrect as it does not describe a type of nutritional deficiency. Choice B, 'Primary deficiency,' is incorrect as it refers to a deficiency caused by decreased intake, not inadequate absorption. Choice D, 'Codependent,' is incorrect as it is unrelated to the context of nutritional deficiencies.
3. In the US, low iron intake is often associated with?
- A. low intake of fruits and vegetables
- B. pregnancy
- C. high sugar and fat intakes
- D. high protein intake
Correct answer: C
Rationale: Diets high in sugar and fat often lack essential nutrients like iron, leading to a risk of iron deficiency anemia, especially when iron-rich foods are not consumed adequately.

5. A nurse is teaching a client about strategies to prevent constipation. Which of the following statements by the client indicates an understanding of the teaching?
- A. Drinking four to five glasses of water per day will prevent constipation.
- B. I should consume mineral oil once per day.
- C. Eating foods high in fiber will make elimination easier.
- D. I can skip a meal if I feel bloated.
Correct answer: C
Rationale: The correct answer is C. Eating foods high in fiber increases stool bulk and promotes easier elimination, thus preventing constipation. Choices A, B, and D are incorrect. Drinking water is important, but the emphasis should be on high-fiber foods. Mineral oil is not a recommended first-line treatment for constipation, and skipping meals can disrupt regular bowel movements, potentially leading to constipation.
