1. What physiological role does phosphorus play in the body?

• A. Blood clotting, transmission of nerve impulses, muscle contraction, and relaxation
• B. Calcium homeostasis, structural integrity of heart muscle
• C. No known metabolic function, caries-preventing properties
• D. ATP energy release; metabolism of fats, carbohydrates, proteins; regulates acid-base balance

Correct answer: D

Rationale: The correct answer is D. Phosphorus plays a crucial role in ATP energy release, the metabolism of fats, carbohydrates, and proteins, and regulation of acid-base balance. Choices A, B, and C are incorrect. Phosphorus is not directly involved in blood clotting, transmission of nerve impulses, muscle contraction, or calcium homeostasis. It also has known metabolic functions and is not associated with caries prevention.

2. According to the dietary reference intakes, what percentage of your daily calorie intake should ideally come from carbohydrates?

• A. 10-35%
• B. 20-35%
• C. 40-50%
• D. 45-65%

Correct answer: D

Rationale: Carbohydrates should ideally make up 45-65% of your total daily caloric intake, according to the Dietary Reference Intakes (DRIs). This range provides the necessary energy for bodily functions and activities. Choices A, B, and C are incorrect because they fall outside the recommended range for carbohydrate intake based on the DRIs.

3. Mr. CKK is unconscious and was brought to the E.R. Who among the following can give consent for CKK's operation?

• A. Doctor
• B. Nurse
• C. Next of Kin
• D. The Patient

Correct answer: A

Rationale: In the scenario described, when a patient is unconscious and unable to provide consent, the responsibility usually falls on the physician to make decisions regarding the patient's treatment, including obtaining consent for an operation. While nurses play a crucial role in patient care, they typically do not have the authority to provide consent for a major procedure. The next of kin may be consulted for input, but the ultimate decision-making authority lies with the physician. The patient, being unconscious, is unable to provide consent in this situation.

4. Has Healthy People (HP 2020), issued by the U.S. Department of Health and Human Services, resulted in a reduction of deaths from cardiovascular disease, stroke, and some cancers, as well as decreased dental caries in children aged 2 to 4 years and adults aged 53 to 44 years?

• A. Yes, both statements are true.
• B. No, 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: B

Rationale: Both statements are false. While Healthy People (HP 2020) has contributed to a reduction in deaths from cardiovascular disease, stroke, and some cancers, it did not result in decreased dental caries in children aged 2 to 4 years and adults aged 53 to 44 years. Therefore, the correct answer is B. Choice A is incorrect because the second statement is false. Choice C is incorrect as the first statement is also false. Choice D is incorrect as the second statement is false.

5. An estimated _____ percent of persons in the United States who have HIV infection are unaware that they are infected.

• A. 4%
• B. 21%
• C. 34%
• D. 49%

Correct answer: B

Rationale: The correct answer is B: '21%'. Approximately 21% of persons in the United States who have HIV infection are unaware that they are infected. This percentage represents a significant portion of individuals who are not aware of their HIV status, highlighting the importance of increased testing and awareness campaigns. Choices A, C, and D are incorrect as they do not align with the estimated percentage provided in the context.
