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. What is a major feature of the therapeutic lifestyle changes (TLC) recommended for the treatment of high blood cholesterol?

A. Avoiding all foods that contain cholesterol
B. Reducing sodium intake to less than 2 g/day
C. Limiting total fat intake to less than 30% of energy intake
D. Limiting saturated fat intake to less than 7% of energy intake

Correct answer: D

Rationale: The correct answer is D, 'Limiting saturated fat intake to less than 7% of energy intake.' This is a central feature of the therapeutic lifestyle changes (TLC) recommended for treating high blood cholesterol. Saturated fats can increase low-density lipoprotein (LDL) cholesterol, a significant risk factor for heart disease. Choice A is incorrect because while it is recommended to limit cholesterol intake, it's not suggested to avoid all foods containing cholesterol entirely in the TLC. Choice B is also incorrect as although reducing sodium intake is beneficial for controlling blood pressure, it's not specifically targeted in the TLC for managing high cholesterol. Lastly, while limiting total fat intake is a healthy guideline, it's not as specific or effective as limiting saturated fat intake, making choice C also incorrect.

3. What are the best food sources of magnesium?

A. oils, bananas, and pork
B. pizza, potatoes, and tomatoes
C. milk, rice, and apples
D. legumes, whole grains, and chocolate

Correct answer: D

Rationale: The correct answer is D: legumes, whole grains, and chocolate. These foods are rich sources of magnesium, an essential mineral that plays a role in over 300 biochemical reactions in the body. Choices A, B, and C do not contain as high levels of magnesium compared to legumes, whole grains, and chocolate.

4. A 52-year-old male patient recently required surgery for the removal of a large calcium oxalate stone. To prevent further stone formation, the nurse advises against drinking?

A. apple juice
B. tea
C. orange juice
D. coffee

Rationale: Tea contains oxalates, which can contribute to the formation of calcium oxalate stones; therefore, patients prone to kidney stones should avoid excessive tea consumption.
