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. Which systolic blood pressure measurement is classified as prehypertension?

• A. 106 mmHg
• B. 119 mmHg
• C. 130 mmHg
• D. 141 mmHg

Correct answer: B

Rationale: According to the blood pressure classification, a systolic blood pressure between 120-139 mmHg is considered prehypertension. This range indicates an increased risk for developing hypertension if not managed appropriately. Therefore, a systolic blood pressure of 119 mmHg falls into the prehypertension category. A systolic pressure of 106 mmHg is within the normal range, while 130 mmHg and above would be classified as stage 1 and stage 2 hypertension respectively, not prehypertension.

3. Overweight and obesity often accompany conditions such as _____ that limit mobility or result in short stature, which can lead to feeding difficulties.

• A. Parkinson's disease
• B. muscular dystrophy
• C. Down syndrome
• D. multiple sclerosis

Correct answer: C

Rationale: The correct answer is C, Down syndrome. Down syndrome is often associated with short stature and limited mobility, which can contribute to feeding difficulties and obesity. Parkinson's disease (choice A) primarily affects motor function, but it is not typically associated with short stature. Muscular dystrophy (choice B) primarily impacts muscle strength and does not necessarily lead to short stature. Multiple sclerosis (choice D) is a neurological condition affecting the central nervous system and does not directly cause short stature or feeding difficulties as seen in Down syndrome.

4. Which food item interferes with the effectiveness of warfarin?

• A. Cauliflower
• B. Zucchini
• C. Green beans
• D. Broccoli

Correct answer: D

Rationale: Broccoli is high in vitamin K, which can affect the effectiveness of warfarin. Warfarin is an anticoagulant medication that functions by reducing the activity of vitamin K in the body. When one consumes broccoli, which is rich in vitamin K, it could counteract the anticoagulant effect of warfarin, thereby interfering with its effectiveness. On the other hand, cauliflower, zucchini, and green beans do not have significant levels of vitamin K and hence, are not known to impact the effectiveness of warfarin.

5. In cleaning the stoma, the nurse would use which of the following cleaning mediums?

• A. Hydrogen Peroxide, water and mild soap
• B. Providone Iodine, water and mild soap
• C. Alcohol, water and mild soap
• D. Mild soap and water

Correct answer: D

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.
