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. A nurse is instructing teenage girls on the importance of adequate calcium intake throughout their life span to prevent complications. Which complication should the nurse include in the teaching?
- A. Goiter
- B. Osteoporosis
- C. Heart disease
- D. Dental caries
Correct answer: B
Rationale: The correct answer is B: Osteoporosis. Adequate calcium intake throughout life helps prevent osteoporosis, a condition characterized by weak and brittle bones, which is common in older adults. Goiter is caused by an iodine deficiency, not calcium. Heart disease is more related to factors like cholesterol and blood pressure. Dental caries are primarily influenced by oral hygiene and sugar intake, not just calcium.
3. Which consumption pattern of fermentable carbohydrate is considered most cariogenic?
- A. A single exposure to a large quantity
- B. A single exposure to a small quantity
- C. Multiple exposures of small quantities
- D. Multiple exposures followed by chewing sugarless gum
Correct answer: C
Rationale: Multiple exposures of small quantities are considered most cariogenic. The total amount of dietary fermentable carbohydrate seems to matter less than the form and frequency in which it is consumed. Having multiple exposures of even small quantities of fermentable carbohydrate throughout the day promotes a highly cariogenic environment in the mouth. Choices A and B, involving single exposures, are less cariogenic as they do not sustain the fermentation process over time. Choice D suggests a beneficial practice by chewing sugarless gum after exposures, which can reduce the risk, making it less cariogenic compared to multiple exposures of small quantities.
4. Which nutrient is most important for wound healing in a patient post-surgery?
- A. Vitamin C
- B. Protein
- C. Iron
- D. Calcium
Correct answer: B
Rationale: Protein is essential for tissue repair and wound healing.
5. A patient has begun taking furosemide to manage heart failure. What food should the nurse recommend that the patient consume frequently while taking this drug?
- A. legumes
- B. cabbage
- C. peanut butter
- D. bananas
Correct answer: D
Rationale: Furosemide is a diuretic that can lead to potassium loss; therefore, it is recommended that patients consume potassium-rich foods like bananas to prevent hypokalemia.
