1. An advance directive known as a durable power of attorney involves appointing another person called a(n) _____ to act as the decision maker in the event of the patient's incapacitation.

A. witness
B. primary caregiver
C. health care agent
D. state proxy

Correct answer: C

Rationale: The correct answer is 'health care agent.' A health care agent is appointed through a durable power of attorney to make medical decisions on behalf of a patient who becomes incapacitated. The term 'witness' (choice A) is incorrect because a witness only observes the signing of the directive and does not make decisions. 'Primary caregiver' (choice B) is also incorrect as they may provide care but are not necessarily legally empowered to make decisions. 'State proxy' (choice D) is not commonly used in the context of advance directives or health care decision making, making it an incorrect choice.

2. When is Prevident indicated?

A. High caries risk
B. Crown and bridge work
C. Orthodontic decalcification
D. All of the above

Correct answer: D

Rationale: Prevident is indicated for all the situations listed in the choices. It is recommended for patients with a high risk of caries to reduce the risk of tooth decay. It is also used in dental procedures like crown and bridge work to strengthen enamel and prevent cavities. Furthermore, it is utilized for orthodontic decalcification to aid in remineralizing the tooth structure and prevent further damage. Therefore, the correct answer is 'All of the above.' While choices A, B, and C are individually correct, selecting 'All of the above' is the most appropriate as it encompasses all the possible indications for Prevident.

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. The ideal time to begin taking folate to prevent neural tube defects is:

A. Before conception
B. Once pregnancy begins
C. At 6 weeks
D. Upon completion of the first trimester

Correct answer: A

Rationale: Folate is crucial before conception to prevent neural tube defects. Neural tube development occurs early in pregnancy, often before a woman knows she is pregnant.

5. The Acceptable Macronutrient Distribution Ranges state that half of your calories should come from protein.

A. TRUE
B. FALSE
C.
D.

Correct answer: B

Rationale: The statement is FALSE. The Acceptable Macronutrient Distribution Ranges recommend that 10-35% of daily calories come from protein, not half. The remaining calories should be derived from a combination of carbohydrates and fats to ensure a balanced diet. Choosing option A is incorrect because it misinterprets the recommended percentage for protein intake. Options C and D are left blank as they are not applicable to the question.
