1. What is a disadvantage of using a food frequency questionnaire?

A. It does not influence the food choices of the consumer
B. It is not affected by seasonal changes in the diet
C. It is not effective for monitoring short-term changes in food intake
D. It does not take too long to obtain the results

Correct answer: C

Rationale: Option C is correct because a food frequency questionnaire is designed to capture a person's typical food intake over an extended period and is not suitable for monitoring short-term changes in diet. The questionnaire's purpose is to provide insights into long-term dietary patterns rather than immediate changes. Option A is incorrect as the questionnaire does not influence food choices; it merely records them. Option B is also incorrect because, while seasonal changes can impact food availability and thereby influence diet, the questionnaire itself is not affected by these changes. Lastly, option D is incorrect as the time to obtain results from a food frequency questionnaire would depend on the respondent's speed and accuracy rather than being intrinsically linked to the questionnaire.

2. 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.

3. When assessing for criteria that signify malnutrition risk, which element would most likely be included as part of the functional assessment data?

A. severity of illness
B. presence of pressure sores
C. localized edema
D. generalized weakness

Correct answer: D

Rationale: Generalized weakness is a key indicator of malnutrition and is often assessed as part of functional status, reflecting muscle wasting and reduced physical function. The other choices, such as severity of illness, presence of pressure sores, and localized edema, are important factors to consider in a clinical assessment but are not primarily indicative of malnutrition risk. Generalized weakness directly relates to the functional impact of malnutrition on physical performance.

4. For patients with anemia, which vitamin is crucial for the absorption of iron?

A. Vitamin A
B. Vitamin C
C. Vitamin D
D. Vitamin E

Correct answer: B

Rationale: The correct answer is Vitamin C. Vitamin C enhances the absorption of non-heme iron, which is crucial for patients with anemia. Vitamin A (Choice A) is not directly involved in iron absorption. Vitamin D (Choice C) helps with calcium absorption, not iron. Vitamin E (Choice D) does not have a significant role in iron absorption.
