1. Approximately 75% of reputable producers of bottled water use groundwater as their water source. Plain tap water is the most natural source of fluids.

• A. Both statements are true.
• B. Both statements are false.
• C. The first statement is true; the second is false.
• D. The first statement is false; the second is true.

Correct answer: A

Rationale: Both statements are true. Approximately 75% of reputable producers of bottled water use groundwater as their water source, which is the same source as the public water supply. Plain tap water, coming from underground sources or reservoirs, is indeed a natural source of fluids. The first statement is supported by the fact that groundwater is a common source for bottled water due to its purity and taste. The second statement is true as tap water is sourced from natural reservoirs or underground aquifers in most cases, making it a natural fluid source for consumption. Other choices are incorrect because both statements are factually accurate based on common practices in the production and sourcing of bottled water and tap water.

2. What is the desirable resting systolic blood pressure for adults?

• A. <130 mmHg>
• B. <105 mmHg>
• C. <120 mmHg>
• D. <140 mmHg>

Correct answer: C

Rationale: The desirable resting systolic blood pressure for adults is less than 120 mmHg. This blood pressure is associated with a lower risk of cardiovascular disease. Measurements higher than 120 mmHg (choices A and D) indicate elevated blood pressure, which can lead to hypertension and other health complications if not managed. A reading of less than 105 mmHg (choice B) could indicate low blood pressure, which also poses health risks such as dizziness and fainting.

3. What best describes a task of the registered dietitian?

• A. administering total parenteral nutrition
• B. administering formula through feeding tubes
• C. prescribing diet orders
• D. conducting nutrition assessments

Correct answer: D

Rationale: The correct answer is D, conducting nutrition assessments. Registered dietitians are responsible for assessing an individual's nutritional status, dietary intake, and health needs. This assessment forms the basis for developing personalized nutrition care plans. Choices A and B involve the administration of specialized nutrition support, which is typically done by healthcare providers with specific training in those areas. Choice C, prescribing diet orders, may fall outside the scope of practice for a dietitian as they focus more on assessment, education, and counseling related to nutrition rather than prescribing medical treatments.

4. Which condition is an example of a potential cause of gastritis?

• A. bile reflux
• B. low salt intake
• C. hypophosphatasia
• D. gallstones

Correct answer: A

Rationale: Bile reflux is a potential cause of gastritis as it can irritate the stomach lining when bile backs up into the stomach. Choices B, C, and D do not directly cause gastritis. Low salt intake is not a common cause of gastritis. Hypophosphatasia is a rare genetic disorder affecting bone development, not the stomach. Gallstones, while related to the gallbladder, are not a direct cause of gastritis.

5. What is the primary goal of a dental hygienist when making dietary recommendations for a patient with a new dental prosthesis?

• A. To promote healing and repair by ensuring an adequate and nutrient-dense diet
• B. To promote healing and repair by recommending consumption of only liquids for the first week
• C. To promote a balanced diet by recommending a variety of fibrous foods
• D. To encourage the patient to become accustomed to the prosthesis by eating as usual

Correct answer: A

Rationale: The primary goal of a dental hygienist when making dietary recommendations for a patient with a new dental prosthesis is to promote healing and repair. This can be achieved by ensuring the patient maintains an adequate and nutrient-dense diet. This is why option 'A' is the correct answer. Option 'B' is incorrect because while liquids are easier to consume with a new dental prosthesis, a diet consisting only of liquids for a week may not provide all necessary nutrients. Option 'C' is incorrect because while a variety of fibrous foods can contribute to a healthy diet, it's not specifically relevant to the healing and adjustment to a new dental prosthesis. Option 'D' is incorrect because eating as usual may not be feasible or comfortable for a patient with a new prosthesis, and it doesn't specifically focus on promoting healing and repair.
