1. What kinds of foods do people who live in food deserts typically lack?

• A. fresh fruits and vegetables
• B. energy-dense foods
• C. beef or pork products
• D. grains and cereals

Correct answer: A

Rationale: Correct Answer: Fresh fruits and vegetables are often unavailable in food deserts, where access to nutritious, perishable foods is limited. Choice B, energy-dense foods, is incorrect because these are more likely to be available in food deserts, contributing to health issues. Choice C, beef or pork products, is incorrect as the focus is on the lack of fresh produce. Choice D, grains and cereals, is incorrect as these are staple foods that are more commonly found even in areas classified as food deserts.

2. While the client has a pulse oximeter on his fingertip, you notice that sunlight is shining on the area where the oximeter is. Your action will be to:

• A. Set and turn on the alarm of the oximeter
• B. Do nothing since there is no identified problem
• C. Cover the fingertip sensor with a towel or bedsheet
• D. Change the location of the sensor every four hours

Correct answer: B

Rationale: In this scenario, the correct action is to do nothing since there is no identified problem with the sunlight shining on the area where the oximeter is placed. The functionality of the oximeter is not affected by sunlight, so covering it or changing its location unnecessarily could disrupt the monitoring process. Setting the alarm or changing the sensor location every four hours is not indicated in this situation and may lead to unnecessary interventions. It's essential to assess the situation carefully and intervene only when necessary, ensuring that care provided is appropriate and effective.

3. Although a balanced diet is essential for tissue healing and repair, which of the following should the dental hygienist identify as the nutrient of highest priority for a patient with gingivitis or periodontal disease?

• A. Carbohydrates
• B. Vitamin C
• C. Vitamin D
• D. Monosaccharides

Correct answer: B

Rationale: Vitamin C is crucial for collagen production and connective tissue repair, making it a key nutrient for healing gingival tissues in patients with gingivitis or periodontal disease. Carbohydrates are a source of energy and not directly related to tissue repair. Vitamin D is important for bone health but is not the highest priority for gingival tissue healing. Monosaccharides are simple sugars and not as essential for tissue repair as Vitamin C.

4. Each statement regarding the correlation between vitamin D and sun exposure is accurate, except one. Which is the exception?

• A. The body can produce sufficient amounts of vitamin D from sunlight.
• B. UV radiation can convert a precursor of vitamin D to vitamin D3 by penetrating uncovered skin.
• C. Sunscreen blocks the formation of vitamin D3.
• D. By the age of 70 years, the skin generally produces vitamin D at only half the level it did at the age of 20 years.

Correct answer: C

Rationale: While UV radiation can penetrate uncovered skin and convert a precursor of vitamin D to vitamin D3, sunscreen does block the formation of vitamin D3. Sunscreen is recommended by dermatologists to prevent sunburn and reduce the risk of skin cancer. The other choices are correct: the body can produce sufficient vitamin D from sunlight, UV radiation can convert a precursor of vitamin D to vitamin D3, and skin generally produces less vitamin D as a person ages.

5. What is the most common nutritional disorder for the older adult?

• A. Obesity
• B. Underweight
• C. Vitamin deficiency
• D. Dehydration

Correct answer: A

Rationale: The correct answer is A: Obesity. Among older adults, obesity is the most common nutritional disorder. This is often attributed to reduced physical activity levels and changes in metabolism that occur with aging. Choice B (Underweight) is less common among older adults as compared to obesity. While choices C (Vitamin deficiency) and D (Dehydration) are important nutritional issues, they are generally not as prevalent as obesity in the older adult population.
