Nursing Elites

1. 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.

2. A person who consumes mostly pre-packaged meals is likely consuming too much ____.

• A. iron
• B. zinc
• C. sodium
• D. riboflavin

Correct answer: C

Rationale: Pre-packaged meals often contain high levels of sodium, which can contribute to hypertension and other health issues when consumed in excess.

3. Located in the middle of the brain, what organ is responsible for satiety and hunger?

• A. Medulla Oblongata
• B. Pituitary Gland
• C. Hypothalamus
• D. Parathyroid

Correct answer: C

Rationale: The hypothalamus, located in the middle of the brain, plays a crucial role in regulating hunger and satiety. It contains specific regions that control appetite and feeding behavior. The Medulla Oblongata (Choice A) is responsible for regulating vital functions like heartbeat and breathing, not hunger. The Pituitary Gland (Choice B) is an endocrine gland that secretes hormones but is not primarily involved in hunger regulation. The Parathyroid (Choice D) is responsible for regulating calcium levels in the body and not related to hunger or satiety.

4. To raise HDL levels, what is Mrs. Smith advised to do?

• A. quit smoking
• B. increase dietary sodium
• C. take iron supplements
• D. avoid dairy products

Correct answer: A

Rationale: The correct answer is A: quit smoking. Smoking lowers HDL levels, so quitting smoking is crucial to raising HDL levels. Increasing dietary sodium (choice B) is not linked to raising HDL levels and can have negative effects on cardiovascular health. Taking iron supplements (choice C) is not directly related to increasing HDL levels. Avoiding dairy products (choice D) is not necessary to raise HDL levels; in fact, some dairy products like low-fat options can be part of a heart-healthy diet.

5. What are the responsibilities of a nurse towards a patient?

• A. A registered nurse is responsible for a group of patients from their admission to their discharge
• B. A registered nurse only provides care for the patient with the assistance of nursing aides
• C. A nurse's only responsibility is to perform administrative duties in a healthcare setting
• D. A nurse's only responsibility is to maintain hospital equipment

Correct answer: A

Rationale: A registered nurse is responsible for a group of patients from their admission to their discharge. This responsibility encompasses assessing patient needs, formulating care plans, administering medications, monitoring patient progress, and coordinating with other members of the healthcare team. Choice B is not entirely accurate because, even though nurses often work with nursing aides, the nurses themselves hold the ultimate responsibility for the overall care of the patient. Choices C and D are incorrect as they depict an incomplete and inaccurate representation of a nurse's role, which extends beyond administrative duties and equipment maintenance to primarily focus on direct patient care.
